The fastest on-chain orderbook decentralized exchange (DEX) built on Solana, offering low fees and instant settlement.
Phoenix is a decentralized exchange (DEX) protocol featuring the fastest on-chain orderbook in decentralized finance (DeFi). Built on Solana, it enables users to place limit orders with exceptional speed, efficiency, and transparency. Trades are confirmed on-chain within approximately 0.5 seconds, leveraging Solana's high-performance network to deliver ultra-low transaction fees and near-instant settlement. Phoenix's crankless design allows funds to be immediately available for withdrawal once orders are filled, improving user experience by eliminating delays common in traditional on-chain orderbooks.
The protocol is fully non-custodial and trustless, ensuring users maintain complete control over their private keys and assets. Its open-source codebase is audited by OtterSec and includes a bug bounty program, emphasizing security and transparency. Phoenix enforces price-time priority on its orderbooks, meaning orders closest to the mid price fill first, and among orders at the same price, earlier orders get priority. This design supports fair and efficient trade execution.
Phoenix targets DeFi developers and financial institutions seeking a high-performance decentralized trading infrastructure. Integration requires interaction with Solana blockchain and the Phoenix smart contracts, with comprehensive documentation and developer tools available. Users can verify deployed code matches the open-source repository using the Solana Verify CLI. The protocol's low protocol fees (as low as 0.02% per trade) and minimal network fees (~$0.0002 per transaction) make it cost-effective for high-frequency trading and liquidity provision. Developers can get started by accessing the GitBook documentation and exploring the open-source code on GitHub.
Decentralized exchanges often suffer from slow trade execution, high fees, and delayed settlement due to on-chain limitations. Many on-chain orderbooks require manual cranking, causing latency and poor user experience. Additionally, lack of transparency and custodial risks reduce trust in DeFi trading platforms.
