infra402

x402 revives HTTP 402 for internet-native payments, enabling services (and AI agents) to declare payment requirements directly in HTTP and settle instantly on-chain. On EVM chains, today's x402 implementations typically rely on EIP-3009 (transferWithAuthorization) so users can sign once and let a facilitator sponsor gas for a true "signature-only" flow. Many widely used assets on BNB Chain (e.g., USDT) don't implement EIP-3009, which blocks the out-of-the-box gasless UX. Infra402 removes that blocker.
