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. --- 📣SPOTIFY PREMIUM RSS FEED | USE CODE: SPOTIFY24 https://bankless.cc/spotify-premium --- BANKLESS SPONSOR TOOLS: 🪙FRAXNET | MINT, REDEEM, EARN https://bankless.cc/fraxnet 🦄UNISWAP | SWAP ON UNICHAIN https://bankless.cc/unichain 🛞MANTLE | MODULAR L2 NETWORK https://bankless.cc/Mantle 💤EIGHT SLEEP | IMPROVE YOUR SLEEP https://bankless.cc/eight-sleep 💠BIT DIGITAL ($BTBT) | ETH TREASURY https://bankless.cc/bit-digital We’re being compensated by Bit Digital (NASDAQ BTBT) for this segment promoting their company and BTBT.
