什么是 x402r Refund Protocol？

x402r is the refund extension for the x402 payment protocol. Enable secure, transparent, and automated refund processing for internet-native payments with escrow protection. We’ve been building for three months and won an Ethereum Foundation and Coinbase hackathon with it.
