The leaders on Atomic Swaps are Komodo Platform, they have the Atomic Dex, https://github.com/KomodoPlatform/atomicDEX-Pro they were the first project to bridge BTC blochains to Ethereum, that was about three years ago. Nowadays with that techology, they can bridge up to 90% of all blockchains, I am sure they can guide us. Actually a collaboration initiative can work for both projects, if Hive is interesed in a close approach, I know the main developer (JL777) he is always trying to help good initiatives.
