thirdweb x402
x402 middleware from thirdweb that integrates with their smart contract and wallet tooling.
Using USDC on thirdweb x402
thirdweb's x402 integration lets developers add per-request USDC payments to any application using thirdweb's existing infrastructure. It connects with thirdweb's wallet SDK (supporting embedded wallets, smart wallets, and external wallets), contract deployment tools, and analytics dashboard. This makes it easy to go from zero to a working x402 payment flow without stitching together multiple libraries. thirdweb's x402 support works on Base and Ethereum, and benefits from thirdweb's broader ecosystem of over 70,000 developers.
