Gateway now supports ERC-1271 for transfer authorization.
In this Release Notes episode, HJ from Circle DevRel explains how to authorize Gateway transfers with ERC-1271 by setting contractSigner: true on the burn-intent request.
Gateway gives developers a unified USDC balance across supported chains. With ERC-1271 support, a smart contract can sign a Gateway burn intent through its own isValidSignature logic.
This episode covers:
- Adding contractSigner: true when posting a burn intent to /v1/transfer
- How Gateway validates contract signatures via ERC-1271
- Read-only validation and replay-resistance requirements
