$ARB ARB coin is the governance token of the Arbitrum ecosystem. Arbitrum is a Layer 2 expansion solution created by Offchain Labs to solve the congestion and high fee problems on Ethereum. Arbitrum aims to improve the scalability and efficiency of the blockchain while maintaining trustless security. The main role of the ARB token is to achieve decentralized governance of the Arbitrum ecosystem. ARB holders can vote to decide proposals that affect Arbitrum features, protocol upgrades, fund allocation, and security committee elections.

ARB tokens will not be used to pay any fees on the Arbitrum chain, and chain fees will still be paid through ETH. Arbitrum tokens (ARB) were officially issued on March 23, 2023, with a total supply of 1 billion, of which 12.75% were allocated to early users and DAOs built on Arbitrum. ARB tokens can be traded and used on multiple well-known cryptocurrency exchanges and platforms, such as Huobi, Binance, Gate.io, Uniswap, OKEx, etc.

The initial supply of ARB is 10 billion, and new ARB can be minted at a rate of up to 2% of its supply per year, with the first minting taking effect on March 15, 2024. The distribution of ARB tokens decentralizes the governance of Arbitrum One and Arbitrum Nova and their underlying protocols, and ARB holders can jointly shape the future of the Arbitrum protocol and chain.
