Arbitrum Token Bridge Contracts

The Arbitrum Token Bridge is a decentralized application that uses Nitro's arbitrary cross-chain messaging system to implement an ERC20 token bridge between an EVM compatible base-chain and an Arbitrum chain.

All public Arbitrum chains include a canonical token bridge deployment.

The Token Bridge includes "Gateway" contracts — pairs of contracts that implement a particular token-bridging flow — as well as "Gateway Router" contracts, which map tokens to their respective gateways.

See the developer documentation for more info.
