Arbitrum vs Uniswap FAQ
- What is Arbitrum?
- Arbitrum is an optimistic rollup on Ethereum built by Offchain Labs. Mainnet launched August 2021 as Arbitrum One; a second chain — Arbitrum Nova — targets gaming/social with AnyTrust data availability. By early 2026 it is consistently the largest L2 by TVL, rivalled only by Base.
- What does "optimistic rollup" mean?
- Transactions posted to L1 are assumed valid by default. A 7-day challenge window lets any watcher submit a fraud proof to revert fraudulent batches. The sequencer (currently centralised, operated by Offchain Labs) orders transactions; decentralising it is on the roadmap. Security ultimately inherits from Ethereum.
- What is Uniswap?
- Uniswap is a decentralised exchange launched 2018 by Hayden Adams, pioneering the automated market maker (AMM) model. UNI is the governance token, airdropped to early users in September 2020. It gives holders voting power over the Uniswap DAO treasury and protocol parameters.
- Where does Uniswap run?
- Uniswap V3 and V4 are live on Ethereum mainnet and every major L2 (Arbitrum, Optimism, Base, Polygon) plus several non-EVM chains via Uniswap X. V4 introduced "hooks" — customisable pool logic — enabling dynamic fees, on-chain limit orders, and MEV capture at the pool level.
- How do Arbitrum and Uniswap compare?
- Arbitrum (ARB): Largest Ethereum L2 by TVL. Optimistic rollup, Stylus (Rust) support. Launched 2021, runs Optimistic Rollup (Ethereum L2). Uniswap (UNI): Largest AMM DEX token. Governance-only; V4 hooks unlock custom pool logic. Launched 2018, runs Ethereum (ERC-20) + multi-chain deployment.
