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 Resources: - Transfer from a smart contract account: https://developers.circle.com/gateway/howtos/transfer-with-erc-1271 - ERC-1271 programmable authorization: https://developers.circle.com/gateway/references/erc-1271 - Transfer unified USDC balance: https://developers.circle.com/gateway/howtos/transfer-unified-usdc-balance - Manage delegates how-to: https://developers.circle.com/gateway/howtos/manage-delegates - Gateway technical guide: https://developers.circle.com/gateway/references/technical-guide - Gateway docs: https://developers.circle.com/gateway - ERC-1271: https://eips.ethereum.org/EIPS/eip-1271
