Receive on-chain button leads to create invoice screen

[yanascz]

Describe the bug

I can understand described behaviour on LN layer but not on the base layer. As a user, I'd expect the above action to generate a new on-chain address.

In addition, when I generate an invoice this way and accidentally close the screen with QR code, the on-chain address is no longer accessible from nowhere.

Reproduce

1. Tap the On-chain box.
2. Tap the Receive button.

Zeus version

v0.7.1

Node interface

LND (REST)

Network

Device

Device operating system

One of the challenges here is with LNDHub: detecting whether or not the backend supports on-chain receiving or not.

LNBits and LNBank do not support it, whereas vanilla LNDHub does.

Main problem 'Receive on-chain button leads to create invoice screen' is fixed meanwhile. It leads to a screen where you can see a QR and text representation of an on-chain address.

In addition, when I generate an invoice this way and accidentally close the screen with QR code, the on-chain address is no longer accessible from nowhere.

This is still the case though. It doesn't matter which way you do it:

1. Lightning -> Receive, choose 'Unified' or 'On-chain' on the bottom
2. Bitcoin -> Receive
   -> You will not be able to access the BTC address which was displayed before.

This is usually not a problem since you can create millions of BTC addresses, but what if I presented a BTC address QR to somebody and expect a payment, and then later want to check/track/do whatever with that exact address on a block explorer e.g.? Not possible.

So, @kaloudis why don't we also save BTC address generation in activity as well?

• In case it was done via Lightning -> Receive, we could add the BTC address to the data (in case amount threshold was hit and 'Unified' and 'On-chain' was available)
• In case it was done via Bitcoin -> Receive, we could make an object in activity without amount and expiration etc., but only "Requested Payment", timestamp, BTC address

Am I missing something or would that be possible without any technical problems?

@myxmaster one thing to consider here is we can only track addresses generated in Zeus. if you're using a second interface like CLI or a web UI, you can easily have an incomplete picture of your addresses

@myxmaster let's close this one out and take discussion of on-chain address history to #1930 - I have a discovery
