Circle Gateway Adds ERC-1271 Support

August 4, 2026

Circle Gateway now supports ERC-1271, enabling smart contracts, smart wallets, and other applications to access unified USDC balances while preserving their existing authorization logic. Key benefits include:

No delegate accounts required
Existing policy controls preserved
Expanded crosschain compatibility

The upgrade makes it easier for onchain applications to integrate USDC without modifying their security model.
