Blockchains interoperability is one of the hardest problems to be solved in the nowadays blockchain ecosystem that contains thousands of different blockchains. This paper focuses on swapping assets from a blockchain to another without a trusted third party. One recent scheme for atomically swapping assets, Atomic Cross Chain Swap (ACCS), has been formally analyzed in [2]. This paper proposes an implementation of an ACCS between the two most valued crypto-currencies today: Bitcoin and Ether.
