$ARB ARB (Arbitrum) is a Layer 2 scaling solution for Ethereum, designed to improve transaction speed and reduce costs while maintaining security. The ARB token is the native governance token of the Arbitrum ecosystem, allowing holders to vote on key protocol decisions via the Arbitrum DAO. Launched by Offchain Labs, Arbitrum uses optimistic rollups to bundle multiple transactions into one, easing the load on Ethereum's mainnet. It supports decentralized applications (dApps) with faster, cheaper transactions. With growing adoption among DeFi platforms and strong developer interest, ARB plays a crucial role in Ethereum's scalability and the broader Web3 ecosystem.
