Gasless transfer availability
FurlPay has implemented an EIP-3009 gas-sponsored USDC transfer flow, but the production relayer is not configured. Gasless sending is not currently available as a live service.
Do not promise a zero-gas transfer
/api/rails before offering a sponsored transfer. If the rail is unconfigured or its status cannot be read, stop the flow.How the development flow works
EIP-3009 lets a USDC holder sign an authorization that binds the sender, recipient, amount and expiry. A configured relayer can submit it and pay network gas. The signature alone is not a transfer, and the relayer cannot change its signed fields.
Network fees
When a user submits a transaction directly from their wallet, the wallet needs the network's gas token and the transaction may incur network fees. A FurlPay sponsor may pay those fees only when a production rail is enabled and its current conditions are shown to the user.
Developer status
The implementation and route contract are documented for integration planning. Do not enable customer-facing gasless transfers based only on code presence. See agent payment protocols and the service availability overview.
