According to Odaily Planet Daily, Sui Bridge has integrated Circle's cross-chain transmission 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 on both the origin chain and the target chain.
CCTP destroys the original USDC and mints new USDC on the target chain. Since the value of USDC is pegged to the US dollar, CCTP does not require currency conversion.
