Arbitrum One chain
Overview
Arbitrum One is an Ethereum Layer 2 scaling solution that uses optimistic rollup technology to increase transaction throughput and reduce costs while maintaining Ethereum-level security. It processes transactions off-chain and posts compressed data to Ethereum, with fraud proofs ensuring correctness. The network is fully compatible with Ethereum's existing smart contracts and tooling.
Within the DeFi Intel graph, Arbitrum One connects to 20 tracked entities, most strongly to Ethereum, Offchain Labs, Offchain Labs.

Frequently asked questions
What is Arbitrum One?
Arbitrum One is a Layer 2 rollup chain on Ethereum that uses optimistic rollups to scale transactions. It is developed by Offchain Labs and is fully EVM-compatible.
How does Arbitrum One ensure security without full on-chain execution?
Arbitrum One relies on a fraud proof system where validators can challenge suspicious transactions. If a fraud proof is successful, the invalid state is reverted and the dishonest party is penalized.
What is the difference between Arbitrum One and Arbitrum Nova?
Arbitrum One is an optimistic rollup designed for general-purpose DeFi and dApps, while Arbitrum Nova is a separate chain using AnyTrust technology for lower-fee use cases like gaming and social applications, assuming a lower data availability threshold.
What is Arbitrum One connected to?
In the DeFi Intel knowledge graph, Arbitrum One is linked to 20 other tracked entities, most strongly to Ethereum, Offchain Labs, Offchain Labs.
