The CCTP module is technically supported by Circle Internet Financial LLC. (issuer of $USDC and $EURC) to achieve the free $USDC cross-chain bridge function. Shadow Exchange has developed an independent dApp based on this module, called CCTP.TO.
This dApp is open to everyone and provides free $USDC cross-chain bridges service.
Function description
CCTP.TO supports both version 1 and version 2 of CCTP and allows bridging between the following 9 blockchains that support native $USDC: Ethereum, Avalanche, Arbitrum, Optimism, Base, Solana, Polygon, Noble, and Sonic.
This tool does not charge any fees, and anyone can use it to transfer native $USDC from one supported chain to another supported chain.
In the June interface update, CCTP v1 and v2 have been integrated into the cross-chain interface of Shadow Exchange, allowing users to transfer $USDC assets for free.
