About

thirdweb's x402 stack lets a client pay for HTTP 402 responses, using a React hook that handles wallet connection and payment errors. On the server, a settlePayment function and facilitator add payment to an endpoint. Payment tokens must support ERC-2612 permit or ERC-3009 authorization, such as USDC on all chains.

Use cases: payments-billing, crypto-web3
