CHAIN-NEUTRAL HUMAN APPROVAL

One payment desk. Three rails.

에이전트는 조건을 준비할 뿐입니다. EVM·Solana·Gno 지갑은 사람이 네트워크, 자산, 금액, 수취인을 확인한 뒤 직접 서명합니다.

MAINNET BOUNDARY

Mainnets are independently locked by default

Ethereum and Solana mainnet routes require an independent opt-in, a chain-specific recipient, RPC configuration and a compatible production facilitator. Gno keeps its own separate lock.

HUMAN-IN-THE-LOOP

No server-held payer keys

EIP-712 or the Solana v0 transaction is signed in the connected wallet. The server receives only the signed x402 payload.
