According to Odaily Planet Daily, Sui Bridge has integrated Circle's cross-chain transfer protocol CCTP, allowing users to directly transfer USDC between Sui and eight other blockchains.
CCTP supports USDC transfers between Arbitrum, Avalanche, Base, Ethereum, Noble, OP Mainnet, Polygon PoS, and Solana. Users need to pay transaction fees for both the source chain and the target chain.
CCTP will burn the original USDC and mint new USDC on the target chain. Since USDC is pegged to the US dollar, CCTP does not require currency conversion.
