About Arbitrum

Arbitrum (ARB) is an Ethereum Layer 2 scaling solution developed by Offchain Labs. It uses optimistic rollup technology to batch transactions off-chain and submit compressed data to Ethereum, achieving significant cost savings while inheriting Ethereum's security. Launched in 2021, Arbitrum has consistently maintained the largest total value locked (TVL) among all Layer 2 networks. The ecosystem includes Arbitrum One (the main rollup chain), Arbitrum Nova (an AnyTrust chain optimized for gaming and social), and Arbitrum Orbit (a framework for building Layer 3 chains). Arbitrum is home to major DeFi protocols including GMX, Camelot, Radiant Capital, and Pendle. The ARB token is used for governance of the Arbitrum DAO, which controls a significant treasury.
