UTOx402

UTOx402 is an on-chain payment protocol built on the Binance Smart Chain (BSC), designed to enable secure, instant, and non-custodial digital payments. Inspired by the HTTP 402 “Payment Required” status code, UTOx402 introduces a new way to handle automated, on-chain invoice payments via API — without registration, emails, or OAuth complexity. With UTOx402, users and developers can easily create, send, and verify blockchain-based invoices directly on BSC. Every transaction flows from wallet to wallet, ensuring full ownership and eliminating intermediaries or centralized custody. The API-first architecture allows seamless integration with both Web2 and Web3 systems, making it ideal for microtransactions, SaaS tools, pay-per-API access, content gating, and IoT billing.
