Arbitrum Bridge
Project Links
Description
Arbitrum Bridge is a decentralized token-bridging application comprising a web interface and canonical contracts deployed across parent and Arbitrum child chains. It supports deposits and withdrawals of ETH and ERC-20 tokens across relationships such as Ethereum and Arbitrum One, Ethereum and Arbitrum Nova, and Arbitrum One and Layer 3 Arbitrum chains. The implementation uses Arbitrum cross-chain messaging together with paired gateway and router contracts, while the interface lets users select networks and tokens, initiate transfers, monitor transactions, and claim completed withdrawals. Offchain Labs implemented the canonical bridge and maintains its interface and contract repositories.Category: Bridge
