Accept dollars on Base. USDC is a fully-backed digital dollar that settles quickly for low network fees, without card-network chargebacks or processor fees. x402 separately lets software agents pay HTTP services. If you accept a B20 token, standard ERC-20 transfers work unchanged and memo variants can carry an order reference in the payment transaction.
