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!

Hi ProductHunt community!

We’re building x402r, a refund and arbitration protocol for agentic payments.

AI agents can’t use credit cards because fees kill micropayments, agents can’t be KYC’d, and existing dispute system is too slow and messy for agentic payments.

x402 and Stablecoins work for agentic payments, but they’re now missing the one critical thing that credit cards have: refunds and dispute resolution. We saw this firsthand at ETH Devconnect in Argentina, even in places with massive stablecoin adoption and need, people still rely on cards because they trust the refund system.

x402r solves this problem by adding refunds and arbitration to stablecoin payments. Payments are held in an escrow smart contract, and if there's a dispute, an independent arbiter resolves it. Works for both agents and humans.

We just put out the v2 of the protocol and wanted to share it with the ProductHunt community!
