Gateway API

The Gateway API enables cross-chain USDC transfers using Circle’s Cross-Chain Transfer Protocol (CCTP). CCTP burns USDC on the source chain and mints it natively on the destination, eliminating bridge risk and wrapped token exposure.

What you can do

Deposit USDC into the Gateway from any supported chain
Withdraw USDC to any supported destination chain
Check Gateway balances and transaction history
Estimate fees for cross-chain transfers
