AuthOnce is a non-custodial crypto subscription protocol built on Base Network. Merchants accept gasless USDC recurring payments using EIP-2612 permit-based authorization for standard wallets, or a fresh per-cycle ERC-1271 signature for smart-contract and AI-agent wallets. Funds are pulled automatically every billing cycle, straight to the merchant's wallet. No custody. No chargebacks. 0.5% flat protocol fee.
Unlike custodial crypto payment processors, AuthOnce never holds funds. Every payment is a single atomic transaction from subscriber wallet to merchant wallet.
Subscribers sign a single EIP-2612 permit off-chain — no gas, no on-chain approval transaction. The AuthOnce keeper executes recurring pulls on each billing date.
Configurable 1–30 day grace period built into the smart contract. Failed payments trigger automatic retries before a subscription expires.
