Atomic Swaps with Helium

kbambridge · March 22, 2020, 8:11pm

I would like to create something that will allow for atomic swaps of Helium with other currencies. From looking at the blockchain API docs it looks like Helium blockchain does not natively support HTLC. Are there any features in the blockchain that I should know about or are planned that can help with this?

Hi, there’s a PR for the Wallet CLI that will enable this. No API support yet:
