# Gateway API

> Move USDC natively across chains using Circle's CCTP protocol.

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
