Dan Romero, co-founder of decentralized social media protocol Farcaster, launched a new in-app payment feature on Friday. The new tool, built for Farcaster client side Warpcast, uses USDC to pay stablecoins with one click, via a user's profile or messaging platform for the app. The feature solves a longstanding problem of using cryptocurrency to pay people, namely looking up someone's alphanumeric wallet address. Since the Farcaster identity is human readable, it makes the process easier.
