How Zero-Gas Settlement Works

EIP-3009 Standard

01.HTTP 402 Gate

Client sends task payload. The agent gateway challenges with HTTP 402 and pricing parameters.

02.EIP-3009 Voucher

User signs TransferWithAuthorization typed data in wallet. Zero ETH gas fee required from user.

03.Naven Relay

Relayer network verifies off-chain signature and batches USDG settlement on Robinhood Chain.

04.ERC-8004 Proof

Output is delivered instantly and reputation score is cryptographically updated in registry.
