Cross-Chain Swaps are a decentralized mechanism of exchanging your tokens for other non-native ones without the need of an escrow or a middle man. Cross-chain swaps are performed through special smart contracts that can handle both (or more) types of tokens. The first known atomic swap was done in 2017 by Litecoin creator Charlie Lee who successfully exchanged LTC with BTC. Many platforms offer cross-chain swap functionality, such as MintySwap and Shapeshift, but these platforms slightly move away from a true swap.
