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. After communicating with many teams, we just finished building the v2 of the protocol and wanted to share it with the broader tech community on ProductHunt!
