Cross-Chain Transfer Protocol (CCTP) Integration in Interport
Interport Finance integrated the Cross-Chain Transfer Protocol (CCTP) to provide users with advanced cross-chain functionality. This integration enhances the trading experience on Interport by enabling users to perform cross-chain transfers with increased efficiency and security.

What is CCTP?

The Cross-Chain Transfer Protocol (CCTP) is a permissionless on-chain utility designed to facilitate the transfer of USDC tokens across different blockchain networks. It allows for the burning of native USDC tokens on the source chain and the minting of an equivalent amount of native USDC tokens on the destination chain. CCTP empowers developers to embed this functionality into their applications, enabling users to transfer USDC in a capital-efficient manner across chains.
Now available on Ethereum, Arbitrum, and Avalanche.

How does CCTP work?

In the context of Interport, the integration of CCTP simplifies the process of cross-chain transfers for users. The following steps outline how CCTP operates within the Interport ecosystem:
1. Swap source token to USDC with the best trading rate due to Meta DEX aggregation 2. Burning USDC on the source chain: To initiate a transfer of USDC from one blockchain to another
3. After the USDC tokens are burned on the source chain, Circle, a trusted entity, observes and attests to the burn event. The application requests a signed attestation from Circle, which serves as authorization to mint the equivalent amount of USDC on the destination chain.
4. Minting USDC on the destination chain: With the attestation obtained from Circle, the application triggers the minting process on the destination chain. The specified amount of USDC tokens is minted on the destination chain. 5. Swapping USDC to the destination asset with the best rate due to Meta DEX aggregation.
