SwapTrade

Secure, transparent, and decentralized trading powered by Soroban on the Stellar network.

SwapTrade is an open-source decentralized exchange (DEX) smart contract suite built with Soroban, the smart contract platform for the Stellar network. It provides the core building blocks for creating, managing, and settling token trades in a secure and trustless environment while leveraging Stellar's fast settlement and low transaction costs.

Designed with modularity and extensibility in mind, SwapTrade serves as a foundation for developers building decentralized finance (DeFi) applications on Stellar. The project emphasizes security, transparency, and developer experience, making it suitable for contributors, auditors, and ecosystem builders alike.

Why SwapTrade?

Traditional exchanges depend on centralized operators to custody assets and execute trades. SwapTrade replaces that model with Soroban smart contracts that execute trading logic directly on-chain.

With SwapTrade:

• Assets remain under users' control until execution.
• Trading rules are enforced by immutable smart contracts.
• Every transaction is transparent and verifiable.
• Developers can extend the protocol for new DeFi applications.
• Anyone can integrate the contracts into wallets, marketplaces, or trading interfaces.
