Introduction
Welcome to the DotSwap Developer Documentation — your gateway to building on the leading decentralized exchange infrastructure for Bitcoin-native assets.
What is DotSwap?
DotSwap is a trustless, non-custodial trading protocol built specifically for the Bitcoin ecosystem. By leveraging Partially Signed Bitcoin Transactions (PSBTs), multi-signature wallets, and UTXO-based liquidity models, DotSwap empowers users to swap Bitcoin-native assets directly — without wrapped tokens, centralized custodians, or smart contracts.
At its core is DotSwap Nexus, a coordination layer and liquidity aggregator that enables self-hosted market makers to contribute to a unified order flow while retaining full control of their funds.
