@mica000 I believe the main thing missing from this early mockup is the ability to set fees, which we could drop in above the send button:

Relevant to this work in anticipation of extended functionality: BIP-0322 and BIP-0174

Choosing a BTC fee has been updated on a separate user flow:

Makes sense! Mind updating this initial screen e.g. removing fees and total since that'll come later? I imagine you have ideas for how to spruce it up in general, too.

I've modified this issue to include both fully and partially signed transactions, either broadcasted by the wallet or simply returned to the app.

Speaking with @mica000 about this, it's like the new confirmation screen found here but will a standardized app request header unit:

@radicleart would use this immediately for sBTC bridge bitcoin transactions.

[markmhendrickson]

Looks generally good! Though we should move the fee setting to a subsequent modal just like we want it for regular BTC sends in the wallet, yea?

[markmhendrickson]

Also header should be more like "Send Bitcoin" than "buy-in-ustx"

And note how we'll have the app's domain (and favicon) here but not its name per se.

@mica000 hmm relevant how so? I'd say replace with whatever design you want implemented these days. I don't believe @fbwoolf has started on this UI work yet iirc

Nope, I haven't started this yet.

[crypticmeta]

would this enable us to do a tx with both segwit and taproot address?

example:

payment with btc
receive ordinal with taproot

I tried implementing this using PSBT, but failed miserably.

[markmhendrickson]

@crypticmeta Yep! We intend for it to work with both types.
