}Gas Sponsorship
Prepare gas-sponsored transaction
Prepare a gas-sponsored transaction from signed EIP-712 typed data.
Submit the owner’s off-chain signature along with the EIP-712 typed data that was signed. Returns an unsigned transaction for the sender to sign and broadcast.
How gas sponsorship works:
- Call an endpoint with
gas_sponsorship=true(e.g., /earn/transfer, /earn/manage, /credit/transfer) to get EIP-712 typed data - Owner signs the typed data off-chain
- Submit signature + typed data to this endpoint
- Sender signs and broadcasts the returned transaction, paying gas on behalf of the owner
Note: For gas-sponsored deposits via /earn/transfer or /credit/transfer, the owner must first set up a Permit2 allowance using /approve_transfer (once per token).
