  • Atomic Swap

    Atomic swap is a smart contract technology that enables exchange of one cryptocurrency for another without using centralized intermediaries, such as exchanges.

    Atomic swaps can take place directly between blockchains of different cryptocurrencies or they can be conducted off-chain, away from the main blockchain. They first came into prominence in September 2017, when an atomic swap between Decred and Litecoin was conducted.
