Episode description

Without a doubt, the introduction of stablecoins has vastly increased overall crypto liquidity, adoption and real-world use cases as they offered a safe haven against the industry’s volatility, especially during bearmarkets. However, despite being extremely efficient, the main stablecoin actors (i.e. Circle & Tether) are centralised entities. Many attempts have been made to create a reliable decentralised stablecoin, but regulations and the resounding collapse of Terra’s UST have only pushed towards more established, yet centralised, variants.

f(x) is a new generation CDP (collateralised debt position) protocol that offers on-chain perpetual trading for BTC & ETH with near-0 funding rates and a novel liquidation mechanism which protects users against hard liquidations. The leverage component is powered by emitting fxUSD, the protocol’s decentralised stablecoin, which boasts robust peg-keeping mechanisms, the main one being fxSAVE’s stability pool. The fxSAVE strategy bestows nearly 10% APY to the yield-bearing fxUSD-USDC pair.

Transcript

FX offers 2 products. The first one is a leveraged product. It delivers leverage on EVE and BTC without funding costs. Without borrowing costs, users just pay a one time opening and closing fee and that's it. And in most cases they won't have to pay any fundings. And the difference with regular CDP is that we abstract the looping so we give overexposure to the collateral and we have this very innovative liquidation mechanism that prevents any hard

liquidation. FX protocol is an evolved CDP. Whenever people are longing the collateral, it involves selling the stable coin for more collateral. Different pack keeping mechanisms. The first one is that stability pool on F of X. The stability pool is a yield strategy that takes both FX USD

and USDC as pays assets. Each time FX USD is traded below 1, the USDC from the YE strategy will buy a fixed USD in the market to put it closer to peg, and each time it's traded above 1, it's sold back for USDC and goes back to the stability pool.

Hey guys, I want to tell you about Nosis, a collective of builders creating real tools for real people on the open Internet. Nosis has been around since 2015. In fact, it started as one of Ethereum's very first projects, and today it's grown to a whole ecosystem designed to make open finance actually work for everyday people. At the center of it all is Nosis Chain. It's a low cost, highly decentralized layer, one that's compatible with Etherium and secured by over 300,000 validators.

So whether you're building a DAP, experimenting with D Phi, or working on autonomous agents, Nosis Chain gives you a solid, neutral foundation to build on. But Nosis is more than just infrastructure. It's also tools that people can actually use, like Circles, for example. Let's anyone issue their own digital currency through networks of trust, not banks. And then there's Metri. It's their smart contract wallet that makes it easy to access circles, manage group currencies, and even spend

anywhere. Visa is accepted. Thanks to their integration with Nosus Pay, all this is governed by Nosus Dow where anyone can propose, vote and help guide the network. And if you want to get involved, running a validator is super easy. All you need is 1 GNO and some basic hardware.

To learn more and start building on the open Internet, head to nosus dot IO nosus Building the Open Internet One Block at a Time. Welcome to Epicenter of the show, which talks about technologies, projects and startups driving decentralization and the global blockchain revolution. I'm Sebastian Kuchiro and today I'm here with Cyril, who is our core contributor at FX Protocol. FX is a really interesting yield bearing stablecoin that also

utilizes A perps market. There's an interesting stability mechanism there that we'll get into. And also right now I think it's like probably one of the best yielding stable coins on the market with their stability pool yielding somewhere around like 1213%. So that's that's really sort of compelling and interesting. And I wanted to talk to you soon today about about FX and understand the core mechanism, you know, and also you know how, how they fit in the broader stable corn landscape.

So hey, so nice, nice to see you today. Thanks for joining. Hey, thanks Sebastian for having me. It's a real pleasure to be here today. So, so you're actually based in France. I see you got the Ethereum France T-shirt. What's your like, What's your background? How did you get interested in D5? Like a, you know, have you worked in any of those big French protocols or?

Yeah. I, I, I started D5 because I got wrecked with the crypto markets and I figured I wanted to make yields that and that getting yield on stable coins would be some somehow more predictable income than just betting on, on the market volatility. So and I had to, I had a bit of as funds on my on my company actually. And I went to the bank and I asked for yield opportunities to the bank and as a professional in France, they would offer me .15% APR with a six month look up.

And I figured that it's point. 15% or 15%? No, no, .15 point 15 with a not 1%. Yeah, yeah. So I figured it was a theft and I should find something else. And I heard about Defy at that point. And, and actually what I didn't hear about Defy, I heard about Celsius as I was offering something like 8% and Nexo as well. And I started putting Euro there at the at that time and I figured, OK, how do these guys actually make yields? And this is how I heard about Defy.

And it was right after the Defy summer and I bumped into a French community called Defy France. It's pretty close to maybe Lobster Dow, but for French people. And it's a group of Defy passionate people talking mostly about Defy and with 0 bullshit, it's mostly doing about building stuff. And there's a lot of builders actually in the group. And I started by reading everything, every single message

in that group for months. And I learned a lot of stuff starting practicing Defy as well and getting involved into Defy France by sharing what I learned from the community and organizing meetups in Toulouse. And I've organized almost a meet up a month for the past three years. I just stopped before this summer. And this is how I I got to meet with people that came to the meet up to talk about their their projects and stuff like that and how I got people to reach out to me to get my

opinion and different stuff. And regarding F of X, I did a meet up about F of X in September 23, so right after the first iteration launch. I've been following Aladdin Dao which is the the DAO behind F of X and and as well as concentrator and clever protocols.

I've been following the DAF since the beginning and when I first read about F of XI just loved the design so I figured I should make a meet up about it and shared it on the community and this is how I I started to contribute to the project. Cool. I think like doing meetups is such an underrated kind of low lift thing that you can do early

in your crypto journey. I organized a few meetups back in the day, Lille in the north of France and like, yeah, I know, like, you know, Brian, my Co founder here at Epicenter, like also organized like quite a few minutes in Berlin. And it's such a great way like meet people who, you know, you don't necessarily see online, right, like, but like they come out of the woodwork for the meet ups, right? And they they they it it built. It's like great great way to

build a connection. Yeah, exactly. And it's one of of these few ecosystems left in which you can easily access to people that makes that make the ecosystem and as and you and you can just a gift to the community and and it will just bring so many opportunities, you know, just by being genuinely sharing stuff, it just just meet people and and it brings opportunity. Yeah, yeah.

I guess what I'm trying to say is like, even, you know, even like 15 years into crypto, there's still opportunity for people to like have to. Yeah, exactly. It's like, like I encourage anybody to do that and like what, what's the relationship like? Well, what is Aladdin DAO and the relationship there? And you know someone was already working on FX before you started contributing to it and. Yeah, Yeah, it's a good question. Aladdin DAO is the DAO that

builds F of X protocol. So it's the same team basically. And Aladdin started as an investment DAO something like four years ago and but it quickly created it's first protocol to just to to get what was missing to them in the define landscape. So this they they launched, I wasn't there, I wasn't contributing there at that point, but I was a user. Actually, they launched concentrator, I believe in 2021 maybe or 22. And and then clever, so considerate in a, in a nutshell,

is an auto compounder protocol. So it auto compounds your yields, but instead of compounding into the underlying, it lets you compound into another yield bearing assets such as Steve, for instance, or, or since since Aladdin that has been very close with the Curve ecosystem in the first days, you, you can compound your CRV, for instance, instead of compounding stablecoins. So it's kind of it's a protocol that lets you DCA with your D5 farming basically and that was

so that's the first protocol. It's still around with the over 100 million TBL. And the second is clever that lets you leverage your CVX farming basically with without liquidation. And so the first two protocols are very deep into the Curve and convex ecosystem, while the third one, which is F of X solves the, the, the problem of decentralized Stabrocoins basically. And what I've loved, what I loved about, about the design is that it brings a real decentralized alternative into

the Stabrocoins landscape. And it was the the origin of F of F of X is actually the USDCD peg in March 23, because Aladdin DA with the existing 2 protocols had a treasury mostly made of USDC. And they just figured it's such a nonsense to build defy in, in, in, in on the most centralized infrastructure and to rely on on centralized stable coins and to depend on on Trotfy even such as the SVB failure. And this is how the idea of F of X was raised in the 1st place.

And and if it evolved to what it is today and today we managed to to bootstrap FXUSD to over 100 million market cap as well while having no VC funding while doing things 100% organically. Yeah, No, I I agree that like the the IT, it's, it's, it feels like such a huge failure on the part of the ecosystem.

Sometimes. I think like the fact that centralized Sable coins have of dominance over the stable coin market feels like a pretty big failure on the part of, you know, proponents of decentralized tech. And it's really unfortunate that, you know, protocols like die and, and other decentralized stable coins haven't picked up more, more adoption than than they have. I mean, like there's sizable adoption, right? But it's like it's nowhere near where USDC and Tether are at.

I mean, there's like a lot of regulatory risk there. And also, you know, DPEG risks and, and these sorts of off chain risks, what what is like the kind of core value that you think sort of the core tenants that a decentralized stable coin protocol should embody? Like, you know, if you had to kind of put characteristics on what's like an ideal decentralized stable coin protocol looks like, what would

those be? Yeah, I think for a decentralized stable coin to work, people need to to to trust it to be reliable. So he needs to have a good peg obviously, and and to be liquid enough so that you can come and and buy it and set it in size. And it had, it needs to be collateralized so that the peg actually stays. So it's not just liquidity, but it's actually a good peg by design and good backing and and it also needs to to be scalable. It it all goes back to the stable control lemma.

It needs to be, in my opinion, mostly on chain because so that you can abstract trust from it and just trust the code instead of trusting entities and and people. And yeah, that's that's and and and and it also brings censorship resistance with by by being on chain. So that's all these different key components. I guess that makes a good decentralized stable coin.

In my opinion, the beauty of Ethereum is and, and decentralization is that it abstracts trust and abstracting trust from finance reduce the risk, right? And it's just like people just forget about this and, and, and, and just like the the trust file is used to, to, to, to trust and to have someone to sue if anything goes wrong. And why we can't just avoid trusting people using Ethereum.

And in my opinion, makes a lot of sense to, to embrace that technology and to, to bring and, and this is actually what we do with FOX. We manage to deliver higher risk with lower, higher, sorry, that's higher rewards with lower, lower risks because there is no trust involved. And and in my opinion, that's a, a, a paradigm change that will come at some point with when they most of the new transfer guys would be crypto native and understand that that value

proposition. Yeah, I certainly hope so. I mean like there's there's a, you know, centralized stable coins, you know, have a lot of have a lot of tailwinds. So, you know, and, and they have, I think, like for for that to happen, I mean, you know, it could happen, it could happen that like decentralized stable coins take over.

But they would have to be some catastrophic event that like really erodes the trust in like tether or USDC to the point where, you know, decentralized stable course can kind of like come in and start taking that. I, I don't know that I think that, you know, decentralized stable coins can like slowly start creeping up and, and, and building up issuance to, to really surpass in a meaningful way, you know, the, the main

centralized ones. I don't think, I don't think they will take over because the the centralized one will probably always be more convenient and and scalable That that's that's a fact. But I also believe that centralized table coin will all eventually disappoint at some point. And, and at that point, people will need a reliable alternative to use. And why would you use a more risky stable coin?

So a more trusted stable coin with low risks, while you can most of the time use a decentralized one with higher, higher yields. You know, the idea is just to, to, to offer a reliable alternative. And this is what what we're doing. And and looks like people understand it since the protocol has grown pretty well lately. Yeah, that makes sense. I think. I think also maybe there's still like some lingering fear about decentralized stablecoins, right? Like where with with UST.

So that might also contribute a little bit. I think also generally they're they're, they're harder to understand right then like a centralized stable coin. Like centralized stable coin people know like, hey, there's an institution behind this. There's all these banks, there's like, you know, KPMG audits to save the money's there. I, you know, I get that because that's like the model that most people are familiar with, with the decentralized stablecoin.

Like, you know, you have to listen to our one podcast like this. So like, understand what the fuck's going on and. Again, it goes back to that trust paradigm of, of of the the old word in a, in a way. But yeah, definitely there's a PTSD of of UST and in most people I meet and and when the first question they ask about FXUSD is, is it an algorithmic stable coin because they heard

about this. Yeah. It's dangerous and yeah, now it's fully collateralized with exogenous collaterals distance like stable coin. Cool. Yeah, Well, let let's maybe get into a little bit of how it works. And like the first time we chatted, you described it as sort of an evolution on the CDP model that Maker introduced to the world, I guess back in like 2016.

So maybe maybe using that as a, you know, if that's helpful, using that as a comparison, 'cause I think a lot of people have that model and understand that model. Yeah, you know, how's it work and what are the different components? Yeah, for for people used to the CDP model, it's the easiest way to understand how FX works. It's it's indeed an evolved CDP design in the way that. So FX offers 22 products. The first one is a leveraged product. So it it, it delivers leverage

on EVE and BTC or BTC. You can. You can choose directional leverage with without funding costs, without borrowing costs. Users just pay a one time opening and closing fee and that's it. And in most cases they won't have to pay any fundings. It can happen in very rare occasions, but so it brings predictability in the cost. And the difference with regular CDP is that we abstract the looping.

So we give overexposure to the collateral just just like if you would use ACDP with looping protocols such as Defy Saver or Contango or stuff like that to get directional leverage, we abstract it, we, we include it into the, the, the product. So that's called expositions for the lungs, expositions for the shorts. You get directional leverage up to 7X predictable cost, just a one time fee. And we have this very innovative liquidation mechanism that

prevents any hot liquidation. So you don't you don't get the half or 100 or the the entire position wiped out with a with if the market goes on the opposite side and you get this very progressive liquidation that keeps you as much exposure as possible and reduce the the risk. So on the leverage side, in a way it's a zero stress leverage. It's just a Zen perp if if you want using the CDP model in in the back end. OK. So maybe we'll stop it there and and kind of go over those

different parts yet. So, right. So comparing to the CDP model, CDP you borrow against collateral, but leverage isn't included in the protocol. Typically people get that leverage by going through some external protocol like D5 saver or maybe Insta DAP and they're they're do they're kind of exporting the looping functionality to that protocol and then. Bringing the collateral by Yeah, like of the. Yeah, yeah, it's a huge pain in the ass.

Like I've done this. It's just really painful and kind of scary to do. So like, and then you bring the collateral back and then they'll, you know, you're doing this loop and you may like get some levers from that. F of X has this built in so you can do up to 77X leverage. And then the the other part that you mentioned is that there's a gradual liquidation mechanism, which means that your collateral isn't liquidated in sort of a single transaction, It's more.

It's very progressive. It's progressive, right? So, and I guess I've never thought of this, but like what makes that possible? And why is it that typically lighting protocols don't have a progressive? It's a very good question. Liquidation mechanism. Yeah, thank you for asking this. The why the other CDP don't do this is is because most of them we're. Just lending protocols basically, like, you know, why wouldn't Ave. kind of have this, you know? Progressive. Lending mechanism.

Can't do this because they handle each leverage positions individually. So to make the liquidation profitable, it needs to be large enough so that the the keeper of the liquidator will actually be profitable to by handling the liquidation. And the the main difference with F of X is, is that all the leverage positions are handled together based on the the on on price ticks basically. So we aggregate every positions at risks to together to process

the the liquidations. Meaning the liquidations are profitable even if the individual liquidation is very small. So to to illustrate the the design, if you're familiar with the LTV concept, each time your leverage position crosses 88% LTV, the protocol puts it back at 88% LTV, no matter the amount. It represents the dollar amount, the value of the liquidation so that your position never reaches 95% hard liquidation team.

If that process ever fails and your position reaches 95% LTV, at that point the whole position is liquidated. So. But in most cases it shouldn't happen because yeah, it it it works. So you're kind of socializing the liquidate, the liquidation mechanism, Is that exactly the way we look at it? Yeah, it's a good way of of saying it. Yeah, it's so socialized. OK, interesting. And and no other D5 protocol does this like your lending people. Yeah, recently Fluid came up

with a similar approach. They have this whole base liquidity layer, but it it's way, it's a way bigger machine, you know, because it's a it's a whole lending protocol and decks and and so on. We need it's on the FX side is way syncher it's just two collaterals and and CDP, you know, but they have a a similar approach in a way.

The main difference on their side is I believe that the the liquidation penalty can fluctuates while on F of X it's it's fixed 2.5, on fluid I believe it goes from 1% to 8% so. Maybe just to put this another way, say we compare with Ave. Like Ave. each position is can be liquidated, has to be liquidated individually to protect the underlying collateral. Here, the underlying collateral is kind of pooled to represent

all of the positions. And you know that that collateral is going to secure your position as much as it's going to secure someone else's. And the different positions may have different sort of collateral ratios relative to the overall collateral, which which is where you get this kind of socialization mechanism. So someone else's collateral is kind of like backing your position. Right. Not, not, not exactly.

Your position is actually like your, your position collateral ratio is is monitored, you know, so there's no, you're, you're not actually. Each long position has its own collateral, but it's all cooled together and and all the, all the, the the leverage positions are monitored together. So and instead of of liquidating each position individually, you look at what's at risk on each position considering the current price and you liquidate everything all together.

Is that is that easier way? Yeah, I think, I think that makes more sense. OK. And what kind of complications does this in does this because there's always trade-offs, right. So like what? What's the SO trade off of this approach? Regarding other landing, landing and liquidation design or or even CTPI think it's just it's just better because it enables higher LTV. This is how we we managed to deliver up to 7X while on RV for instance, you would get like 5X stops on on E for BTC.

It is it, it gives us like I liquidating way more progressively. It it's, it's, it's, it's more secure in a way. Right. But is it, are there like unintended trade-offs like for example, like the the fee, you know, the the fees you can charge are lower or like you know, liquidations liquid like liquidators are less efficient. Like there must be some some trade off, right? On the liquidation side, no, I don't think, I don't, I don't think, I can't think of any

trade off here. It's it's actually a more efficient way of of doing things now. I don't think of any trade off on that on that side. Actually the the cost of liquid of the liquidations is like the liquidation penalty, which is a keeper bounty. It's actually the same. It's way lower than on, on other

money markets. For instance, if you compare with RV, when you get liquidated in RV, I believe it's, it's at least 5% penalty or maybe 10. And and the, the liquidation on TV on, on if it's or, or stiff something like 80% while it it's 88 on F of X and, and when you get liquidated, you can get up to 50% of your position instantly rebate. That's a hit. You know, on F of X it can be as small as just .1% of your position wiped out. If the price just touches it and, and goes up again, you

don't, don't get wiped more. The penalty is just .5%. These are our money market. It's, it's way more secure and efficient and it, it brings like relief in terms of how you see liquidations to compare with a regular centralized perp. It's still, since it's on chain, it's the, the liquidation of the TV, even if it's a partial progressive liquidation is still lower than on, on their centralized perp because like liquidations are processed with a 99.5% of TV on, on Binance,

for instance. But it's a, it's just a different approach. You know it's. And so with this approach, you have near capital 100% capital efficiency like border to lending is nearly 100%. No, it's, it's still over collateralized, but it, it's since since it's more efficient, we, it's we, we can have a, a lower collateral overall collateral ratio than on the other CDPS. So it's more capital efficient

than than previous CDPS. It's still obviously less scalable than a centralized stable coin, obviously because it's over collateralized, but still it it brings it a better compromise than anything before. OK. I'm I'm looking at the website, it says that $4 billion for almost $5 billion have been liquidated last month on other perp solutions and FX has 0 liquidations. Yeah, because like the hot liquidations only happened once.

It was in the first days of the the current iteration of the protocol when there wasn't enough keepers processing the the, the the liquidation break. So that's the some position reaches not reached reached 95% LTV and got liquidated. But since that evidence, it wasn't on February the second or something like that, there was a massive liquidation event on the market. And since that dates there, there was no hard liquidations on Evox.

Some got partially reduced in a way, but there was no hard liquidations. And the main, the main, the main point of of this design is that the leverage users keep as much exposure as possible to recover with the market. If the market ever recovers, if they made a bad trade, it won't, it won't save them. You know, if the market just crashes and goes to 0, they will go to 0, you know, but way more progressively than on any other Unchained leverage solution.

Another thing you mentioned is that the that there's no funding rate for the leverage trades. You just have this one time fee. What's unique? What's unique about this approach? What does it enable? It's been it has been done before by Liquidy for instance. With the LUSD it was similar in a way people would just pay a

one time opening fee. But the the main difference here is that CDP elect LUSD could couldn't scale because they had massive peg issues like the the LUSD peg is is not reliable enough to actually hold the LUSD because you end up buying it at 11.05 and setting it at at .99. So it's not reliable enough. And we fixed this by still having this just fixed one time opening fee and closing fee. But we only add a small funding if the stable crime is ever depegged.

And that funding is an an just like most of the fees generated by the protocol are distributed to a stability pool that acts as a peg keeper to attract more USDC earning. That's that's organic yield and helping with supporting FXUSD spec. So we have this organic peg keeping mechanisms that that just work and that let's FXUAD scale pretty well since we launched earlier this year.

Yeah, let's, let's talk about that stability mechanism, the stability pool And there's, there's also, I think like I, I guess FX save is also. Related to here, yeah. Correct. Yeah. So, so, so like what's really impressive here, I think is the yields which range between like 10 and 20%. No, yeah, those, those, those approach Terra level anchor level yields. But yeah, why, why, why is this sustainable? How? How is this sustainable? It's it's a good question.

Yeah, indeed Fxsafe, which is the main yield strategy on the F of X protocol as since we launched it has been one of the best yield, stable yield in Defy. If you look at the dashboard created by Inverse Finance called stable yields.info, you can compare all the main yield bearing stable strategies around such as FXF obviously S Dollar Stack, USR, SCRVUSDSUSDE and stuff like that and and most of

them. And if you get this on different time frames, you see that FXF has been above all the time and like the next one is like 4 points below FXF. And, and that's, that's a huge success for us. We're very, very proud of of this. And, and most, and the main thing is that most of this youth is 100% organic and doesn't imply any human active management. It's 100% smart contracts on chain. There's yeah, nothing to trust as than the, the, the code, you know.

And so to understand what's how it works, maybe I can break down the different, the, the, the back keeping of FX USD. So if you understand that FX protocol is an evolved CDP, whenever people are longing the, the collateral, it involves selling the stable coin, right? Because in the back end the stable coin is sold for more collateral.

So it brings selling pressure. And this is This is why for instance LUSD ended up under peg are are are the the people getting leverage on liquidity ended up being redeemed because USD was massively sold. And we solved it with different Peck keeping mechanisms. The first one is that stability pool on F of X. The stability pool is a yield strategy that takes both FXUSD, the decentralized stablecoin, and USDC as pays assets and it acts as a Peck keeping

mechanism. Each time FXUSD is traded below 1 on on the main liquidity pool which is on curve against USDC. Each time FXUSD is traded below 1, the USDC from the year strategy will buy FXUSD in the market to put it closer to peg. And each time it's traded above 1 it's sold back for USDC and goes back to the stability pool. So that strategy keeps FXUSD spec and to attract capital, the incentives comes from all the the the the fees generated by the protocol.

At the moment, the protocol generates close to $1 million a month and most of it is distributed to the stability pool or the governance truck and lockers. OK. So just just to stop there for a second, so, so the protocol does rely on on USDC at least in the stability mechanism to find its price. Yeah, it's not backed by USDC at any point. But like USDC is the like if you want, if you want any assets on chain to be back to USD, it's back to USDC or USDT.

And actually on chain USDC is the most liquid. So This is why USDC currently is the most liquid device stable coin around. So if you. Is, is, is, is it? Is it? Is it safe to say then that like this mechanism it wouldn't be possible without an on chain stable coin that has a really high peg stability? The the other option would be companies that could handle their redemption with real

dollars, for instance. But yeah, since we don't want to rely on, I guess the biggest company that does this currently is is Circle and and and Tether. But the most liquid on Shine is is circled with USDC. So that's. Currently the obvious choice. At some point if we scale FXUSD enough, we may not need it anymore and people will build liquidity with FXUSD because they want to be paired with

FXUSC. But when you build the stable coin, if you want it to be liquid and at peg, you need to build liquidity with Currently the the the the most obvious choice is USDC. Right. And and so if if there was a USDCD peg, you know, highly unlikely, but like it happened before, right? What happened before and that actually triggered the creation

of FOX? If the the stability pool cannot accept USDC like the USDC peg is monitored and when if ever D pegs, the stability pool won't accept more anymore USDC. So it's exposed but protected from USDCD peg. So you get exposure to both assets FXUSD and USDC, but it's protected from any USDC D peg. So the main risk here in that strategy for any LP is the FXUSD spec. And This is why there's different layers of peg keeping. The first one is the stability pool itself.

And, and, and so the, the yield comes from the protocol economic activities. So people taking leverage, they pay this one time fee I told you about they can have in some, in some situation of funding. And I'll, I'll go through this in a, in a second. And and most of the leverage positions are backed by yield generating assets such as RAP state, EEF and that yield also goes to the stability pool.

So if, but if it's not enough, so actually whenever FXUSD is trade below 1 is actually below .998, the stability pool buys FXUSD the market. But if there's not enough USDC into the stability pool. So whenever the ratio of USDC goes below 5%, we may not have enough USDC to support the PEG. So in that very situation, all the leverage positions get a small funding cost applied to their position. It's temporary and it's it's here to support the PEG.

And that funding cost is the RV boring cost of USDC and that goes to the stability pool to attract more USDC deposits that will support the PEG and and then cut the funding because as, as soon as the distribution of USDC, it goes above 5% again, then the funding is, is off. But if it's not enough, there's, you know, different layers you always have to, you know, anticipate what could go wrong. If it's enough and FXU starts to depend for too long, it means when the EMA 42 minutes of FX

USD on curve goes below .998. So it's pretty small DPEC, but long enough to be modicable, we trigger what I call the DPEC mode. And in in that situation, people can no longer open any long positions. So it prevents any further selling pressure on FXUSD. And at that point, a second layer of funding is applied to their leverage positions, which is way higher. It's, it's 5 or 1010 times the UEDC borrowing costs.

I don't believe it happened yet because the previous layer of keeping were have always been enough. But in that situation, it brings a very high incentive for leverages to to to for either leverages to repay to close their loans because they can buy FX USD cheaper and close with a bigger profit and they can avoid these high fundings.

If they keep their lungs open then it brings a very like like massive yield to the stability pool thus attracting USDC That will cut repair FX USD quickly and and cut the fundings. And there is a one last layer of peg keeping mechanism which is the redemption. When FXUSD is in in the PEG mode, people can can buy it and redeem it against the collateral minus a .5% redeeming fee. So that's sets the worst case

scenario PEG at .995 basically. One question here is like, you know, I'm looking at the stable yields dashboard, which is great by the way. And you know the, the yield, the 30 day average is almost 6 points above the second position, but only has well has less than half the the TBL. And if you look at Athena, Athena has 5.7 billion in TBL with also but the same you know 30 day average, there's about 100 million in TBL as we were recording this on on September

3rd. You know, with yields, with yields so attractive and a mechanism that appears to be sustainable and sort of safe, why in your view, why, why isn't there more TBL on FX? There's probably different reasons for that. First thing is that we are doing things 100% organically. There is no VC backing. So there's no, so we don't get it. We, we had to make all of our connections ourselves, you know, just by reaching out to people and meeting people into events

and stuff like that. And, and the overall protocol TVL is over 400 million now and it's been built 100% organically. So it takes and I guess it takes time to build as you, as you said it previously, it takes time to build trust towards a decentralized stable coin. So for people to actually understand that the team want to rack pool, that it's actually secure and that there's the, the liquidation mechanism works and the, the, the state, the pack keeping mechanism works and and so on.

And that did the yield will also be sustainable. The stable coin would be liquid enough so that people can come and exit in size and stuff like that. It, it, it takes time to, to build that. And we've, we've done that and we, we keep doing it and reaching out to, to getting in touch with more and more people.

But I guess it takes longer when you're doing this just organically and without any massively back token TG event to come and stuff like that, You know, because the token has been liquid from scratch with fixed emissions over the next 50 years. And yeah, there is, it's probably less speculative in a way than other VC back projects. And then obviously Efina is not exactly AD 5 products.

It's it's highly centralized and relies on uncentralized fundings, which makes it obviously more scalable. And if if we were having 5 billion right now, the yield wouldn't be that high. But it's what we observed over the past few months and and scaling the protocol to over 400 million is that it actually scales by growing progressively. The more TV there is into the stability pool, the more leverage activity we observe on the leverage side and the more

fees we collect. And, and when, when you look at the collected fees over each month, you can, it's pretty clear that there's a pattern of, of, of stabilizing these fees and having them way more steady over time and growing steady. I don't know if I exactly answered your questions. I, I went to all different topics, but I guess doing things and you can do not VCs and 100% on chain. It's, it's the probably harder to, to, to, to scale a protocol

that way. But in my opinion, and our mission with F of X and Aladdin DAO is to build stuff that will last for decades, if not centuries. And so, yeah, we're here for the long term. Do you think that like with, you know, the track record now that you've built, you know, this TVL and and a, you know, a, a peg that has held and kind of demonstrated that this works?

Do you think that it would be useful to now go and like raise money to accelerate growth, to accelerate, you know, fundraising into the protocol, marketing, etcetera. Is that something you consider? We don't consider raising money from VCs because it's, but people are free to buy the token on, on the market. And it's if people do it actually helps because there's other strategies which are

incentivized with the the token. But we're, but it, it definitely helps on one side is that when we talk to new funds and stuff like that. And it's way easier now that the, the, the, the stable coin is more liquid and, and the protocol is bigger than in the in the beginning. So it helps to, to raise in a way stable TVL for the stability pool because the more TVL there is in the stability pool, the more volume we can process on the reverse side because it, it

can be PEC keeps. And so yeah, it helps on and we, and we've definitely seen the difference. For instance, we were discussing it with Paul, another team member like went to ECC with me this year as well as last year. And we've seen a major difference between the two editions in how people were interacting with us. Like when when we're talking to people and other builders, like last year, we felt like they were things.

Oh, that's interesting. Let's see how it goes, you know, and now it was mostly, wow, guys, Congrats on Congrats on the growth. And it definitely it's way easier to to build partnerships when people already heard about the protocol and and start trusting it. So I wanted to switch gears a little bit. You you guys published an article a couple of days ago on your Twitter. It's Ethereum security model and strategic importance of decentralized stable coins.

Yeah, give give me a jest of like what you're arguing for in this article. And you know how how you're thinking about, you know, Ethereum security long term.

Yeah. So, yeah, the idea, the idea of the article is what it was to, to point out that the, the value secured bar if you're in, in centralized asset mostly, which is, which are real world assets and USDT and USDC and stuff like that is going so high that at some point these guys and, and today's Tether tomorrow, it could be another entity has major weights into any, into the, the, the, the protocol security, for instance, if there is any hot fork tomorrow for a

new update, for instance, and that that major centralized entity doesn't want to support it, what's going to happen? You know, and by supporting all these centralized entities, we make that possible. We make, it's may, may not be a technical issue because obviously it's, it's very hard to compromise the proof of stake, but it could be a political issue at some point and, and, and economic issue.

And, and the, the idea is not to say, as I told you earlier, that we should replace centralized table coins with decentralized, but the idea is, is that we want to make sure that there's always an, an alternative that you can use in most cases and just use centralized solutions when it's absolutely needed. And I like to compare some decentralization with privacy, for instance, It's not, it's not white or black, you know, it's

not, it's not binary. You don't, you, you cannot be totally private and, and anonymous on Internet. It's, it's a, it's a scope, you know, and I know people decentralize decentralization. The scope is some kind of a meme, but it's actually true. You do your best, you just do your best. And if you can, you can use private product in most cases, like let's say in for search engines, you can use DuckDuckGo most of the time.

And if you don't find the answer, then you'll go on Google. And it's actually better than using Google all the time and giving them all your private data. And it's, I think it's pretty much the same thing. If, if you can achieve what you want to achieve with your stables using the decentralized 1, there is no point in using a centralized 1.

So if you can get better yields while staying decentralized, you should just do it. And whenever you want to off ramp, because today on on off ramp goes through centralized solutions, then you can go with the centralized solution for that very moment. But in yeah, that's, I guess that's the main idea of what we wanted the the message we wanted to pass with that article. I mean, and I think it makes sense to kind of promote the use of decentralized stable coins.

But like, yeah, it was, as we were saying earlier in the conversation, it's like, you know, at this point, USDC and Tether are so ingrained. It's like it, it almost feels like a little bit of like Ethereum's Achilles heel that, you know, we've built like the ecosystem has built all this amazing decentralized infrastructure only to recreate kind of similar systems that exist in tradfire.

And yeah, the the it's not, it's not clear like what, what the solution is there to kind of mitigate for this as a as a space. Yeah, it's, I think it's a shame, especially when there there are actual, actual reliable alternatives. It's always a compromise between decentralization and, and convenience. You know, if it's convenient, if it's not convenient, you won't do it. It's just like ecology as well. Is, is, is very similar. People won't recycle if it's a

pain to recycle. If they can just do it very easily, they will do it. And and as it and, and now that I believe we we brought a design that is convenient, reliable and secure and, and, and with attractive yields, then why are you using anything else you know? Now one, one other thing I wanted to talk about is kind of where FX sits within the broader perps landscape. So, you know, you guys are competing with Gearbox, GMX and

Hyper Liquid and DYDX. It's a, it's a market that's very dynamic and it's changing all the time. It's like 2 years ago, DYDX was, you know, leading that market, had a lot of traction and now that's sort of lost prominence. Now everyone's kind of focused on Hyper Liquid. And I, I think it is, there is a big part of that that is driven by incentives that's also like driven by capital. And you know, like Hyper Liquid has a lot of money.

How do you guys succeed in that space and, you know, maintain relevance long term when we know that like really well capitalized projects. I do IDX, you know, have lost prominence since in in such a such a short period. And who knows me like maybe hyper liquid in two years from now is like totally irrelevant in something new came along and it's much more interesting. Yeah, maybe.

We don't know. Yeah, I think we mostly do our own path in that market, in that very competitive market, as you stated by we have our own blue ocean. I don't know if you heard about that book, but it's like we have our niche market in a way because we're not exactly a perp, we're not exactly ACDP. We're kind of in between delivering 0 stress leverage. And for many people, getting a leverage position just is a headache. You know, they don't sleep well and they are very nervous and

they get liquidated. We've seen that James Wynn guy getting liquidated all the time and if that guy had been longing or, or trading on F of X, he would still be rich, you know, and, and we, we bring a solution to these guys basically. I don't know. I don't know who that is, but I feel his pain. Yeah, it's a it's a guy on on X that's shares his trades and people just observe. And there was another one fund, I don't remember the the name.

And these guys just keep getting liquidated and a hyper liquid. And, and I've seen there's not even a a meme saying hyper liquidated. That's a good one. Because the other thing is that on all these semi centralized solutions, there is more risk. And, and on the hyper liquid side, there is a massive trust me, bro stuff on this on the Oracle side, and we've seen it recently. People got liquidated for no reasons on I don't recall what's what ticker it it, it cannot happen on F of X.

Everything is 100% on chain. There's no, there's no, there's no to. To play devil's advocate here, like, like you know, there, there is kind of an Oracle and that Oracle is the US is like the Treasury bonds that are like backing the USDC that they're backing the USDC peg, right, because that that's a mechanism that's in that enables the

stability pool to function. I think it like sure there's there's no Oracle and there's maybe no centralized Oracle, but there is a reliance on some centralized thing that. Yeah, of of. Of course F of X relies on chain link as an Oracle just like all Defy. And obviously we we were talking about Taylor being a, a, a democlist sword for defy earlier and and chaining is another one

obviously. But yeah, as yeah, there is a reliance on, on chaining on, on, on F of X and and on USD spec, yes And no, not, not exactly because as I told you, like for instance the stability pool and FXA which is built on top of the stability pool is protected from from any USDC. OK. Maybe not vulnerable, but it like it relies on on the price on that price feed if you will like that, that's kind of the the equivalent of a price feed.

But we believe that so far Chain Inc is the most secure and reliable Oracle provider, and if chaining fails on the E for BTC Oracle, I guess F of X is going to be the least of your problems. Yeah, yeah, yeah. It'd be, it'd be great to have just like a simulation where that happens just to see like you know how how we just all get rugged. Like a Defy dystopian story.

Yeah, yeah, just just like build the simulation where you know, the, the, the, the, the, the, the chain link Oracle price for ether BTC just goes off haywire and then what happens? Well, I I don't have a because I I'm not the technical guy in the

team. I I don't recall the exact Oracle design, but if I recall correctly there is different safeguards in the Oracle design on on F of X. Looking to the future, like Ethereum aspires to secure hundreds of billions, trillions in in RW as like stable coins are becoming a large part of the kind of crypto narrative. Institutions are hopping on the stable coin.

So train there. I think we all kind of anticipate a proliferation of stable coins with many branded stable coins like PayPal is just like one of many. I think that will come. What are the opportunities here, I think for us as an ecosystem, and where does F of X fit in there? Yeah.

So again, very good question. It it we actually already see opportunities and I think I will also answer in a different way one of your previous questions regarding how we can compete and and why the TBL is lower than Efinas for instance. These products since they are not hardcore define in a way that they're C defy stuff. They are already institution ready, you know, they can talk to institutions and they can build, they can sign contracts, actual legal contracts, not spot

contracts with these guys. And so that these institutions can deploy capital. I know for instance, usual scaled like crazy by onboarding capital that was had no idea about crypto in the 1st place. That's that's crazy. They managed to scale to two 2 billion, if I recall correctly, with people from all around the world that had never done any transaction. You know, and, and, and as a Defy protocol is, is way harder because these institutions don't

want to hear about this. And, and hopefully there's solutions now and there's new protocols filling that gap between OG Defy in a way and, and, and, and institutions. And we're currently working on a product with different partners such such as Lagun Finance 9, Summit, Nexus, Mutwald, APC custody solutions to build a tailored product for institutions so that institutions could harness the FXFX save yield in a very Safeway. And you're actually the first person I'd I'd talk about it

publicly. The idea is to call this FX safe because it could. It would be the FX safe without the defy risks all created and and and institution ready. So that's a way to embrace the arrival of institutional money. And the other way is all these new stable coins you mentioned, I don't really see them as competitors because most of them are very attracted with our organic yields and some of them

are already harnessing them. Many of these new yield bearing stable coins are made of other yield bearing stable coins on, on harnessing, on chain or off chain yields. And they actually use FX save or, or stability pool in the back end. So they contribute to, to our growth in a way. So there's, it's not just centralized solution versus decentralized solutions.

There is a synergy between the, the, the 2 worlds and it's actually good because in the first places I could, I could see it in the like the good guys and the bad guys way. But it's actually, we can build synergies and, and, and these guys can help us bring build the alternative to what they're doing. Well, that's a great note to end on, said, Hey, thanks so much for spending the time on Epicenter Day. And yeah, looking forward to seeing, looking forward to seeing FX go up and to the

right. Yeah, yeah, thank you very much for having me. If you enjoyed that episode, feel free to to join the Aladindao Discord. It's a very open community. We all started by popping up on on the Discord and asking questions and sharing ideas about the design. So it's always a pleasure to to meet new people and and discuss things, discuss defy between passionate people. Great. Thanks, David. Cheers. Thank you very much. Bye.
