The Stablecoin Chain Wars: Codex’s Bet on On-Chain FX | Cofounder Haonan Li

Payment chains are heating up. Not every “stablecoin chain” is playing the same game.
Codex cofounder and CEO Haonan Li joins David to map the real landscape: what neutrality looks like in practice, why the bottleneck isn’t TPS but fiat-to-stable friction, and how on-chain FX could pull global flows.
We dig into the Bear-Chain incentive trap. Why Codex chose to build as an Ethereum L2. The case for app-specific rollups that return value to ETH. And the growing split between projects that bundle value toward Ethereum and those that pull it away.
