ARB Arbitrum Rank #63 $0.2225 ▲ 2.93%

Arbitrum is an Ethereum Layer 2 scaling network that processes transactions off the main chain while inheriting Ethereum's security model. Built as an optimistic rollup, it batches transactions and posts compressed data back to Ethereum, which significantly reduces gas costs while preserving a development environment that closely mirrors Ethereum's. Arbitrum hosts one of the largest Layer 2 ecosystems by total value locked, supporting a wide range of decentralized applications, including decentralized exchanges, perpetual trading platforms, lending protocols, and liquid staking services. The ARB token functions as the governance token of the Arbitrum DAO. Holders can vote on proposals that shape the protocol's direction, including technical upgrades, treasury allocations, and parameter changes. The token is deployed on Ethereum and serves as the primary coordination mechanism for the Arbitrum community, which also includes the Arbitrum Nova chain designed for cost-sensitive applications. As one of the flagship Ethereum scaling projects, Arbitrum is positioned within the broader Ethereum and smart contract platform landscape, with backing from a number of notable crypto investment firms.
