Circle CCTP

Circle's Cross-Chain Transfer Protocol (CCTP) is a permissionless on-chain utility that facilitates USDC transfers between blockchains via native burning and minting. CCTP eliminates the need for bridges to lock assets during cross-chain transfers. With CCTP:

1. USDC is burned on the source chain

2. A signed attestation is fetched from Circle

3. USDC in minted on the destination chain

Wanchain served as a launch partner during the initial launch of CCTP in 2023. Since then. CCTP has been integrated seamlessly in WanBridge. When a user initiates USDC cross-chain transfers using the WanBridge, the bridge will default to CCTP if it is available. If CCTP is not available, the bridge will use WanBridge’s standard lock, mint, burn, and unlock mechanisms.
