LND: ability to use full UTXO during channel open or on-chain payment

[kaloudis]

https://api.lightning.community/#estimatefee

We can use this to calculate fees for coin control so users can use their full UTXO

This doesn't have everything we need. Need some changes upstream in LND. Tracking here: lightningnetwork/lnd#6949

@hieblmi excellent progress. looking forward to this

[hieblmi]

Same, but lightningnetwork/lnd#6903 needs to get in first :D

@kaloudis both PRs here were merged -> more power to Zeus

[kaloudis]

@hieblmi amazing. great work!

@kaloudis
Will this solve the issue in Zeus of being able to:

1. Hit send
2. Input bitcoin on-chain address
3. Select desired UTXO(s)
4. Select desired miner fee (sat/vB)
5. Hit fundmax flag
6. Send entire UTXO to address minus fees

Hi @expatri0tic, the features added so far only allow utxo control for channel openings. You are referring to sending on-chain transactions through Zeus. There is active work on an lnd PR to add manual coin selection. This could then be integrated into Zeus. See PR lightningnetwork/lnd#8516
