The best DEXes on Arbitrum, in one place. Oku compares Arbitrum's DEX liquidity in real time and routes your trade through the cheapest path, with no extra fees.
What is a DEX on Arbitrum?
A decentralized exchange (DEX) lets you trade tokens on Arbitrum directly from your wallet, with no account, no custody, and no middleman. Arbitrum's DEX liquidity includes Uniswap and other onchain venues. Prices and depth differ from one venue to the next, so the best price isn't always in the same place. Oku aggregates Arbitrum's DEX liquidity into a single interface: you enter a trade once, and Oku routes it for the best execution. You get the best price on Arbitrum without checking venues yourself, and Oku charges 0% fees on top.

What is Arbitrum?
Arbitrum is an optimistic rollup that scales Ethereum by executing transactions on a separate chain and posting proofs back to L1. It's the largest Ethereum L2 by total value locked, with a mature DeFi ecosystem spanning GMX, Pendle, Camelot, and dozens of protocols that found product-market fit here before expanding elsewhere. Gas fees are a small fraction of Ethereum mainnet while preserving Ethereum-equivalent security. The native token is ETH for gas, with ARB serving as the governance token for the Arbitrum DAO, which controls the protocol treasury and upgrade decisions. Arbitrum is particularly strong for perpetuals, yield strategies, and any application where Ethereum's security matters but its fees don't. Bridging to Arbitrum is one of the most common cross-chain flows in crypto.
