About Arbitrum

Arbitrum is an Ethereum Layer 2 scaling solution that uses optimistic rollup technology to deliver faster and cheaper transactions while inheriting Ethereum's security. Developed by Offchain Labs, Arbitrum has become one of the most popular L2 networks with a thriving DeFi ecosystem including major protocols like GMX, Camelot, and Radiant Capital. The network launched its native ARB governance token in March 2023. Arbitrum supports full EVM compatibility, making it easy for developers to deploy existing Ethereum smart contracts.
