An atomic swap is a technology that allows two parties to exchange different cryptocurrencies directly from their respective wallets without needing a centralized intermediary. While most modern DEXs use liquidity pools and smart contracts (like Uniswap), the principle of an atomic swap ▴ trustless, simultaneous exchange ▴ is foundational to the non-custodial nature of DEX trading enabled by smart contracts.
