List of Decentralised Exchange projects on Starknet (2026)

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.

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.

Rango Exchange is a decentralized exchange aggregator that finds optimal routes for token swaps across multiple blockchains. It aggregates decentralized exchanges and bridges, evaluating many possible paths to identify efficient, secure, and cost-effective routes between tokens on different networks. An intents-based execution layer lets users complete swaps, bridging, lending, staking, and other actions through a single request handled by a solver network. The platform serves traders and everyday users seeking cross-chain liquidity without manually bridging assets themselves.

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.

OpenOcean Gasless Limit Orders lets users place limit orders that execute automatically at a target price without requiring the user to pay gas at order placement. Orders are recorded and filled via a dedicated onchain limit order protocol deployed across multiple chains. The tool sits within the main trading app but relies on its own smart contract system distinct from the swap router.

OpenOcean DEX Aggregator is a decentralized exchange aggregator that routes trades across a wide range of liquidity sources spanning many blockchains. It scans automated market makers, RFQ systems, and other liquidity venues to compute optimal swap paths and return the best available price with minimal slippage. Traders, DeFi protocols, wallets, and AI agents use it to execute swaps directly from self-custodied wallets without paying protocol fees. The same interface also exposes modes for trading tokenized real-world assets and pre-listing tokens, alongside utility tools such as multi-token sweeps, approval revocation, and gas tracking.

OpenOcean Perpetual Trading is a decentralized derivatives interface for opening long or short leveraged positions on tokens and prediction-market outcomes. It routes orders to underlying decentralized perpetual venues and event-outcome markets rather than matching trades itself, giving users a single access point for margin trading and event speculation. The product runs on its own dedicated subdomain separate from the spot swap application.

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. Users supply and borrow assets against tokenized collateral positions using risk tiers, efficiency modes, and dynamic interest rates, with flash loans and automated liquidation protection built in. The platform also runs automated market maker pools with verified, experimental, volatile, stable, and degen risk designs that feed liquidity into the swap function for token exchanges. A bridging module, powered by a cross-chain interoperability partner, moves assets between Starknet and other blockchain networks.

SimpleSwap is a self-custodial swap aggregator that lets users exchange cryptocurrencies and buy crypto with fiat without creating an account. It aggregates liquidity from multiple centralized and decentralized sources and routes trades directly from the user's wallet to the recipient address, offering a choice between fixed and floating rates. The platform is accessible through a website and mobile apps, and registered users can join a tiered loyalty program offering fee discounts and cashback, plus a referral system rewarding users for inviting others.

Ramp Network is a payment infrastructure that enables buying cryptocurrencies with fiat currency, selling cryptocurrencies back to fiat, and swapping between digital assets across multiple blockchains. It operates through a single embeddable widget that businesses integrate into their applications, and a consumer application that individuals use directly. The platform also provides a self-custodial wallet built into its mobile application, allowing users to store and manage supported digital assets without giving up control of their private keys.

Paradex Perpetual Futures Exchange enables users to trade perpetual contracts on a decentralized Layer 2 blockchain. It leverages zk-STARK technology for secure, scalable transactions and supports Ethereum-compatible wallets for easy access. Users benefit from low fees, fast execution, and tools like Vault Traded Funds (VTFs) for advanced trading strategies. Paradex ensures trustless trading while maintaining user ownership of funds and private keys.

Extended Exchange Perpetual Trading lets you trade perpetual contracts with leverage while keeping control of your assets, ensuring security, transparency, and flexibility.

Atomiq DEX implements cross-chain swaps between Bitcoin and Layer 2 networks through Bitcoin light client verification, submarine swaps, and proof-time locked contracts. The system processes transactions via a permissionless network of liquidity providers using a request-for-quote model, while maintaining security through on-chain escrow and proof-of-work validation.

edgeX Exchange is a decentralized derivatives and spot trading platform for perpetual futures on crypto, commodities, and tokenized stocks. It matches orders off-chain through a high-throughput central limit order book and settles trades on-chain through a rollup architecture that inherits Ethereum's security while preserving self-custody of user funds. The platform consolidates perpetuals, spot markets, vaults, and portfolio management in a single application accessible via web and mobile. Cross-collateral margin, multiple order types, and up to 100x leverage are supported for retail and institutional traders. The exchange previously settled through a zero-knowledge rollup and has since transitioned to a modular rollup design for its execution and settlement layers.

Clober DEX is a decentralized exchange running a fully on-chain central limit order book for spot and derivative trading. It uses the LOBSTER matching algorithm with a book manager and segmented segment tree data structures to process limit and market orders at low gas cost, and issues order positions as NFTs. The app also aggregates quotes from external swap routers, offers liquidity vaults where users provide capital to market-making strategies, and includes a bridging interface for moving assets between supported chains. Perpetual futures trading is available alongside spot markets, and the platform runs an points-based rewards program tied to trading and liquidity activity.

Nitro Dex is a decentralized exchange that provides a fully on-chain order book for spot trading, running on a separate test network under its own branding and domain. It uses the same underlying order book matching architecture as Clober, letting users place limit and market orders and view live order book depth and charts. The product maintains an independent user-facing identity and social presence distinct from the main Clober application.
