Promote with Leviathan News25 bps is already baked into the sample app’s env, so the repo is closer to a monetizable FX checkout template than a toy demo. USDC/EURC/cirBTC on Arc gives Circle a clean wedge into the same stable-swap surface Curve and Uniswap fought over, but with Wallets, CCTP/Gateway, and sub-second USDC-gas settlement bundled at the platform layer. Bullish for fintech distribution; less clean for DeFi purists, because routing, custody, and fee capture sit inside Circle’s stack unless builders deliberately break them back out.
