Atomic Swap

An atomic swap is a method of securely exchanging tokens across distinct blockchains, without an intermediary. The code for an atomic swap requires that either transactions on both chains take place, or neither do; the transactions are executed simultaneously. Decred and Litecoin completed the first mainnet atomic swap in 2017. Komodo uses atomic swaps in its BarterDEX decentralized exchange.
