What is Arbitrum One?

Arbitrum One is a Layer-2 network for scaling Ethereum, with low fees, fast transactions, and most of the major DeFi protocols deployed.

Which kind of L2 rollup is Arbitrum?

An optimistic rollup: it assumes transactions are valid, but they can be challenged with a fraud proof during the challenge period. Arbitrum One is fully EVM-compatible, so Ethereum contracts port over easily.

What is the difference between Arbitrum and Arbitrum One?

Arbitrum is the rollup technology, based on fraud proofs. Arbitrum One is a specific L2 chain built with it.

Does Arbitrum have a coin?

Yes — $ARB, an ERC-20 governance token minted on Arbitrum One and distributed as an airdrop to early users and developers.

How do I bridge to Arbitrum?

What makes Arbitrum different?

Arbitrum One is a Layer-2 scaling network for Ethereum. Developed by Offchain Labs and launched in 2021, it uses optimistic rollups, the longest-running rollup design in production, and has grown into the largest L2, home to more DeFi protocols and dApps than any other.

Arbitrum One is the main Arbitrum chain. Arbitrum Nova runs alongside it — a higher-performance chain that accepts additional trust assumptions in exchange for throughput.

Arbitrum hosts some of the deepest DeFi markets outside mainnet — perps, lending, and LPs that mainnet gas prices would make impractical. Zerion detects those positions automatically, values them with rewards and debts included, and bridges assets in and out without a separate bridge app.
