Welcome to HyperDex
Sealed-bid RFQ exchange with zero slippage, non-custodial settlement, and instant Stellar finality.
HyperDex is a sealed-bid Request-for-Quote (RFQ) decentralised exchange built on Stellar and Soroban smart contracts. It lets any trader swap stablecoins at the best possible price, sourced competitively from professional market makers — with zero slippage, no custody risk, and cryptographic settlement finality.
This documentation covers everything you need to understand, use, and build on HyperDex — whether you are a trader making your first swap, a developer integrating the Maker SDK, or a researcher studying the protocol design.
