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.

Nostra Swap executes token exchanges on Starknet using Nostra Pools' liquidity. The protocol routes trades through optimal pools to provide efficient token swaps with minimized slippage.

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.

SimpleSwap Exchange Platform facilitates cryptocurrency trades by analyzing rates from various sources across web and mobile interfaces. The system identifies beneficial trading options based on selected cryptocurrency pairs, offering fixed rates for price stability or floating rates for potential better returns. Users input trading pair selections and recipient addresses through automated processes without account creation requirements. Mobile features include saved addresses, exchange history, and push notifications for enhanced user experience.

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.

Ekubo v3 is a permissionless, ownerless AMM protocol deployed on Starknet, Ethereum, and Arbitrum, consolidating all liquidity pools within a single smart contract to reduce gas costs across multi-hop trades. The protocol uses flash accounting to defer token transfers until transaction completion, settling all pool interactions in a single net transfer. A permissionless extension system enables developers to deploy custom pool logic stableswap curves, TWAMM, and limit orders that integrate natively with the concentrated liquidity core.

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 central limit order book derivatives exchange that processes perpetual futures orders off-chain and settles them to Ethereum via StarkEx zero-knowledge rollups, preserving self-custody throughout. The system supports up to 100x leverage across multiple trading pairs, cross-collateral margin accounts, and multiple order types including limit, market, and conditional orders. Users deposit USDT via Arbitrum, with the platform automatically bridging funds to Ethereum for settlement.

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.

LayerAkira DEX implements a hybrid central limit order book through on-chain smart contracts and off-chain matching engine architecture. The system processes orders off-chain for speed while keeping funds secure in on-chain smart contracts. It enables gasless limit orders, market orders, and order cancellations while facilitating atomic settlement on Starknet. The architecture supports multiple trading pairs, institutional liquidity providers, and integration with external protocols through API endpoints while maintaining price-time priority for trade execution.
