App obtains routing hints from local ChannelUpdate

Open akumaigorodski opened this issue 5 years ago • 1 comments

While a correct way would be to obtain them from remote ChannelUpdate as peer's routing params may be different, see https://gitter.im/ACINQ/developers?at=5db694bc10bd4128a175540d

Yes that's a bug, as a matter of fact we have just discovered it a week ago while working on trampoline routing. There was actually another related bug that we have fixed with https://github.com/ACINQ/eclair/pull/1172. The latter reduces considerably the impact of the former: if peers have different values, there will be a retry and it will work.
