What it does
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!

delegareApr 2026 · delegare.dev · ▲70Hi guys, am building SecureLend.ai and when working on our underwriting agents (free trial, paid after) I had issues with seamless payment options. Of course I looked at x402 which I believe is a great protocol but not a fan of a) sharing private keys with the agent b) having a human in the loop or c) similar workaround e.g. pre-funded wallets So I started building out a solution. For my use case it was important to not only have stablecoins but also a fiat rail which is now implemented using Stripe. Initially I build a mandate system internally but am very glad and big shoutout to the guys…
