ChainPort Bridging Methods | External Cross-Chain Protocols

How External Cross-Chain Transfer Protocols Work

An external cross-chain transfer protocol is a framework that facilitates the movement of native tokens across different blockchain networks that are built and managed by the token issuer.

ChainPort seamlessly integrates with external protocols that allow the burning of native tokens on the source blockchain and the minting of corresponding tokens on the target blockchain simultaneously. ChainPort integrates these protocols developed by third parties for specific assets.

Circle's Cross Chain Transfer Protocol, or CCTP, can be used for USDC bridging, for example. Through the integration of CCTP, USDC holders, and protocols using USDC, can leverage ChainPort to bridge their tokens across Ethereum, Avalanche, Base, Optimism and Arbitrum One quickly, securely, and easily.

Wrapped Asset Bridging

A legacy bridging method creates a wrapped version of an asset on the target chain and locks it with fund segregation on the source chain.

External Cross-Chain Protocols

ChainPort is connected to external bridging protocols that allow permissionless burning and minting of native tokens.

Native Token Bridging

ChainPort provides a platform for bridging assets originally minted on multiple chains but managed by their issuer and guaranteed instant finality.

External Cross-Chain Transfer Protocols Features

Interoperability Across Multiple Blockchains

External Cross-Chain Transfer Protocols enhance interoperability by allowing native tokens to move seamlessly across different blockchain networks.

Secure & Permissionless Transactions

Hybrid Bridging Protocol ensures wrapped tokens like wETH and wBTC are transferred safely and without restrictions, combining robust security with open access.

Integration for Asset-Specific Bridging

External protocols, like Circle's Cross Chain Transfer Protocol (CCTP), can be integrated into advanced cross-chain bridges like ChainPort for specific assets.
