Arbitrum token bridge and peripheral contracts

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.

	Arbitrum is a Layer 2 cryptocurrency platform that makes smart contracts scalable, fast, and private. Arbitrum interoperates closely with Ethereum, so Ethereum developers can easily cross-compile their contracts to run on Arbitrum. Arbitrum achieves these goals through a unique combination of incentives, network protocol design, and virtual machine architecture. Arbitrum has three modes: channels, AnyTrust sidechains, and rollup. Channels and sidechains provide the AnyTrust Guarantee which ensures that the code will run correctly as long as any validator is honest.
