Join Shafu Elfouly, Staff Software Engineer at Circle, for a conversation on x402, an open protocol for web payments, and Circle Agent Stack. We’ll discuss how API providers accept USDC payments from agents, how wallets and spending controls fit into payment flows on Arc, and the setup and funding challenges builders face, followed by live community Q&A.
