List of Decentralised Exchange projects on Optimism (2026)

Uniswap V3 is a version of the Uniswap decentralized exchange protocol built on concentrated liquidity. Liquidity providers choose the price range in which their capital is active, and each pair can have pools at several fee tiers. Each position is held as a non-fungible token carrying its own range and fee settings, and pools also serve as on-chain price oracles.

Uniswap V4 is the current version of the Uniswap decentralized exchange protocol, with every pool held in a single contract. Developers can attach hooks, contracts that add custom logic such as dynamic fees, limit orders, or automated liquidity management, to individual pools. It keeps concentrated liquidity from earlier versions, lowers gas costs for swaps and pool creation, and supports pairs in native ETH.

Uniswap Protocol is automated market maker through smart contracts, enabling peer-to-peer cryptocurrency trading without intermediaries using liquidity pools and constant product formula.

Uniswap V2 is a version of the Uniswap decentralized exchange protocol that pairs any two ERC-20 tokens in a liquidity pool priced by a constant-product formula. Liquidity providers deposit both tokens and earn a share of the fee on every swap in that pool. Each pair also records cumulative prices that other contracts can read as an on-chain price oracle.

Fraxswap is a decentralized exchange based on an automated market maker model with an embedded time-weighted average market maker for large orders. Long-term orders are split into small trades that execute gradually against the pool, limiting price impact on sizeable trades. It is used for protocol rebalancing, liquidity provision, and trustless execution of large trades across multiple blockchains.

Meson Protocol is a decentralized cross-chain swap protocol that moves stablecoins and other assets across multiple blockchains using signature-based atomic swaps instead of traditional bridges. Liquidity providers pre-fund pools on destination chains and match user swap requests, with meta-transactions covering gas costs so users only sign to authorize the transfer. The protocol also supports withdrawing assets directly from centralized exchanges to a range of chains and converting between stablecoins and other currencies through partner services. It serves users seeking fast, low-cost transfers between blockchain networks without wrapping assets or relying on custodial bridges.

Curve DEX is the automated market maker of Curve Finance for swapping stablecoins, liquid staking tokens and volatile assets on Ethereum and other EVM chains. Stableswap pools serve assets that trade near the same price and Cryptoswap pools serve assets whose prices move independently, both with dynamic fees paid to liquidity providers. Anyone can create pools, and many pools also pay CRV rewards to depositors.

Orbiter Swap is a decentralized cross-rollup bridge enabling asset transfers between Ethereum Layer 2 networks through a Maker-Taker mechanism. Users send assets to Maker addresses on source chains while Makers provide equivalent assets on destination chains.

Orbiter Bridge is a cross-rollup bridge and swap interface for moving Ethereum and Bitcoin-native assets between Layer 1 and Layer 2 networks. It uses a Maker-Taker mechanism in which users send assets to Maker addresses on a source chain while Makers release equivalent assets on the destination chain, avoiding a single pooled custodian. The interface also supports direct token swaps during a transfer, and developers can integrate the same routing logic through a REST API, SDK, and embeddable widget. It is used by individuals moving funds across rollups and by third-party applications embedding cross-chain transfers into their own products.

SushiSwap is a multi-chain decentralized exchange that lets users swap tokens and provide liquidity through automated market maker pools. An aggregator routes each swap across multiple liquidity sources to improve pricing, and cross-chain swaps move value between blockchains in one transaction. Liquidity providers earn a share of trading fees, and users can place limit orders and automate recurring purchases with dollar-cost averaging. The platform also offers perpetual futures trading and a launch tool that deploys new tokens with a live market from the start.

ChangeNOW Exchange is a decentralised exchange that lets users swap cryptocurrencies without creating an account.

Ekubo V3 is a decentralized exchange protocol that consolidates all liquidity pools for a deployment within a single smart contract to reduce gas costs across multi-hop trades. Users swap tokens, provide concentrated liquidity, place limit and time-weighted orders, and vote to direct fee-sharing pool incentives by locking the protocol's governance token, with a shared extension system letting developers add custom pool logic such as oracles and automated strategies. The interface supports staking-based voting, where locked stake sets pool swap fees and reward allocation. Protocol fees are collected at the periphery, keeping the core contracts permissionless and ownerless, and governance token holders vote on protocol-level proposals through an onchain governor contract.

SODA Exchange is a DeFi interface built on the SODAX protocol that enables cross-network swaps, lending, borrowing, staking, and liquidity provision through a single application. Trades execute via the SODAX intent-based solver, which resolves cross-network transactions without exposing users to bridge interactions directly. Users can also supply assets to earn yield, borrow against collateral, stake SODA for protocol revenue sharing, and provide AMM liquidity.

Nostra is a decentralized finance application on Starknet that combines lending and borrowing, liquidity pools, token swaps, and cross-chain bridging in one connected-wallet experience.

Developers can integrate WOOFi as a liquidity source for their own applications.

Peer Protocol is a peer-to-peer onramp and offramp that lets users trade crypto directly with other users through everyday payment apps. Sellers deposit stablecoins into onchain escrow and set rates, while buyers pay through their preferred payment method and receive crypto once payment is verified through privacy-preserving proofs. The protocol keeps funds non-custodial throughout, releasing assets directly to a buyer wallet without a middleman holding funds. It supports trading across multiple blockchains and a range of payment applications and fiat currencies.

UniversalX is a cross-chain trading platform that lets users buy and sell tokens across multiple blockchains without manually bridging assets. It routes orders across multiple chains and decentralized exchange venues while applying protections against front-running to seek optimal price execution.

V2 pools can be created permissionlessly, with Vending Machine pools for long-tail tokens, Private Pools for mainstream tokens and Stable Pools for stablecoins.

DODO V3 is a liquidity vault in which liquidity providers supply funds and strategy providers run market-making strategies on them. Strategy providers post collateral, can run strategies off-chain and adjust depth, price and fees, and pay liquidity providers a guaranteed rate that rises with utilization. One V3 pool holds many tokens with separate bid and ask liquidity, which makes rebalancing cheaper in gas.

CryptoRoute is a self-custodial swap engine that lets users exchange crypto assets across blockchain networks without creating an account. Users pick a source and destination asset and network, receive a live quote with fees and a minimum receivable amount, and send funds to a one-time deposit address after address validation. The swap itself routes wallet-to-wallet through an intent-based settlement layer, with a live status page tracking progress until the destination asset arrives. It supports a wide range of assets and networks, including major blockchains and stablecoins, without CryptoRoute ever holding user funds or keys.

TryBit Exchange is a cryptocurrency exchange that lets users swap between digital assets directly on its own dedicated web application. It routes conversions through a third-party exchange operator, allowing users to execute swaps without holding a merchant account with the payment gateway. The exchange supports conversion among a range of cryptocurrencies and stablecoins across multiple blockchains, functioning as a standalone conversion tool separate from the merchant-facing payment gateway.

Balancer V2 is the second version of the Balancer decentralized exchange protocol, with the tokens of every pool held in one Vault contract per network. It supports weighted, stable, liquidity bootstrapping and boosted pools, and the shared Vault lets traders route batch swaps across several pools in one transaction. Its pools are moving to withdrawals only under the protocol's approved wind-down.

Balancer V3 is the current version of the Balancer decentralized exchange protocol, with a redesigned Vault that takes over work earlier pool contracts did themselves. Developers can attach hooks and dynamic swap fees to pools, and boosted pools hold yield-bearing tokens so idle liquidity earns lending yield. Its pools are scheduled to move to withdrawals only under the protocol's approved wind-down, with some partner pools kept open for a short migration period.
