What Arbitrum is and how it works
Arbitrum is an Ethereum layer-2 scaling network (an optimistic rollup) developed by Offchain Labs; Arbitrum One opened on mainnet in 2021. ARB is the governance token airdropped in March 2023.
Transactions execute on layer 2 and are posted to Ethereum in batches, assumed valid with fraud proofs as a safeguard. Gas is paid in ETH; ARB is mainly for DAO governance.
ARB supply and token economics
Initial supply was 10 billion ARB, and the DAO may vote for up to 2% annual inflation; team and investor allocations unlock on a schedule.
What usually moves the price
Layer-2 activity and value locked, unlock timing, DAO treasury decisions and competition with other layer 2s.
These are commonly discussed factors, not a forecast; no single factor guarantees direction.
Where to buy ARB
ARB spot pairs are usually listed on large exchanges such as Binance, OKX, Bybit, Bitget and Gate, but pairs and availability depend on your region and account—check the official listing. Compare fees at the same volume, then check spread and slippage.
Key ARB risks
ARB does not receive network fee revenue, so its value rests largely on governance, and regular unlocks add ongoing supply.
Only use money you can afford to lose entirely, and size positions and liquidation prices before using leverage.
