The best DEXes on Optimism, in one place. Oku compares Optimism's DEX liquidity in real time and routes your trade through the cheapest path, with no extra fees.



A decentralized exchange (DEX) lets you trade tokens on Optimism directly from your wallet, with no account, no custody, and no middleman. Optimism's DEX liquidity includes Velodrome 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 Optimism'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 Optimism without checking venues yourself, and Oku charges 0% fees on top.
Oku aggregates the major DEXes on Optimism and routes every trade to the best price automatically, with no app switching.
Oku compares live quotes across Optimism's DEX routers and splits your trade when that beats a single venue. You always get the strongest available execution.
Oku charges no fee on swaps. You pay only network gas and the underlying DEX's fee. Nothing extra.
Swap, limit orders, LP management, and advanced charting on Optimism, all in one app.
Oku aggregates the leading swap routers it integrates (1inch, 0x, OpenOcean, KyberSwap and more) to tap Optimism's DEX liquidity, including Velodrome, and route every trade to the best available price from one screen.
Optimism is an Ethereum Layer 2 optimistic rollup and one of the original L2 scaling solutions alongside Arbitrum. It pioneered the OP Stack, the open-source rollup framework now used by Base, World Chain, and many others (collectively called the Superchain). ETH is the gas token; OP is the governance token for the Optimism Collective, which distributes retroactive public goods funding to contributors to the ecosystem. The Optimism mainnet hosts a mature set of DeFi protocols including Velodrome, Synthetix (which originated here), Aave, and Uniswap. Gas fees are a small fraction of Ethereum mainnet. For users, bridging to Optimism gives access to the original OP Stack chain and the broader Superchain interoperability story as shared sequencing and cross-chain messaging mature.
Use MetaMask, Coinbase Wallet, WalletConnect, or another Web3 wallet. Make sure you hold a little ETH on Optimism for gas.
Choose what you want to trade. Oku checks Optimism's DEXes and shows you the best available route and price for your size.
Review the quote and confirm in your wallet. Oku executes across the optimal DEX path and your tokens land in your wallet.
The cheapest venue changes with each token and trade size, so there's no single "best" DEX. Velodrome carries deep liquidity on Optimism, but Oku removes the guesswork: it compares Optimism's DEX liquidity in real time and routes your trade to the best price automatically.
Optimism's DEX liquidity includes Velodrome, Uniswap, Curve and other onchain venues. Oku aggregates across them so you can trade the combined liquidity from one interface.
Oku is non-custodial: your funds never leave your wallet until a trade executes. You trade directly against the underlying DEX's audited contracts, and Oku only finds and routes the best path.
You pay Optimism network gas plus the underlying DEX's swap fee. Oku adds 0% on top, with no platform fee.
Bridge assets to Optimism from any chain using Oku's bridge, then trade them on Optimism in the same app. You'll need a small amount of ETH for gas.
A DEX is a single exchange with its own liquidity. A DEX aggregator like Oku searches across many DEXes at once and routes your trade to the best combination, so you get a better price than picking one DEX yourself.
