Key characteristics
- Associated asset: ARB, mainly used for governance of the Arbitrum ecosystem.
- Ethereum layer 2: Arbitrum One batches transactions away from layer 1 and posts the required data and proofs to Ethereum according to its optimistic rollup architecture.
- EVM compatibility: many Ethereum applications, wallets and tools can run on Arbitrum with limited adaptation.
Use cases and ecosystem
- DeFi and on-chain trading: DEXs, lending, perpetuals, liquidity, stablecoins and activity dashboards.
- Web3 applications: games, NFTs, consumer services and application chains built with Arbitrum technologies.
- Market tracking: monitoring ARB, fees, volumes, active addresses and smart-contract interactions through explorers and crypto dashboards.
Consensus and security
Arbitrum relies on Ethereum security for settlement and data availability according to its optimistic rollup model, while also depending on its contracts, validators, sequencers, challenge windows and operational parameters.
Fees and performance
Fees are often lower than Ethereum mainnet, but they vary with network activity, Ethereum data costs and operation type. Real-world costs should be checked at time of use.
