Almost there. Still have a wrong payment calculation.

Almost there. Still have a wrong payment calculation.

Interesting. I've rebased and updated the payment calculation now. As mentioned in the sBTC meeting, I will add the changes from #3576 to this branch since that is such a small PR. Also, it logically makes sense to incorporate those changes here to get the full end-to-end implementation of the wire formats including RPC endpoints.

I'll post here when it's done. Just awaiting @stjepangolemac to finish an update to the RPC PR before I cherry-pick.

[netrome]

This PR has now been updated to include the RPC changes. You can view the RPC changes in isolation here

@kantai and @jcnelson it would be great if you could have a look at this when you have time.

[kantai]

This LGTM, just had a comment on the documentation example.

@jcnelson Everything is green now, we've got two approvals and I've resolved recent conflicts. Feel free to merge if things look good to you.
