Frequently Asked Questions

What is Arbitrum?

Arbitrum is a Layer 2 scaling solution for Ethereum that uses optimistic rollup technology. It processes transactions off-chain in batches and posts compressed data to Ethereum mainnet, achieving dramatically lower gas fees while inheriting Ethereum's security guarantees.

How do optimistic rollups work?

Optimistic rollups assume transactions are valid by default (optimistically) and only run computation through a dispute mechanism if a fraud proof is submitted. This approach allows high throughput while maintaining security, since fraudulent transactions can be challenged and reversed within a 7-day window.

What is the ARB token used for?

ARB is the governance token for the Arbitrum DAO, which controls the Arbitrum One and Nova chains. Token holders vote on protocol upgrades, treasury allocation, and chain parameters. The Arbitrum DAO treasury holds billions in assets to fund ecosystem development.
