We're assembling withdrawal transaction even if user chooses to Cancel

[michalinacienciala]

Steps:

1. Go to withdrawal form and request withdrawal
2. Press 'Cancel' on a Building transaction data... screen
3. Wait

Although you cancelled, dapp is still assembling the transaction in the background:

After ~1-2 min you'll see the transaction to sign:

There are conceptual limitations to cancel the withdrawal related with tBTC SDK. It's currently impossible to resolve the issue.
@r-czajkowski, please elaborate on the issue to give some more context.

We could get rid of the problem by removing the Cancel and X buttons. I've started a discussion about the issue here: https://www.figma.com/design/j2MModNsoiOYNuBBXbWiM8?node-id=13964-6053#875633552.

What happens if user kills the session (ex. close the browser tab)?
What happens when he returns?

@kpyszkowski Can we make this screen more like a progress bar if we want to? Like 0 to 100%? Hypothetically speaking.

If user kills the session during the transaction assembly and logs in again, then there's no assembly still going on in the background, user will not see the transaction to sign (unless they request to withdraw again)

That sounds like the correct behavior for cancel :)
Can't we just fake this when the user press cancel? Apologize if my question is silly.

Technically impossible. It really varies - can take few minutes or even an hour. We don't have any progress to present.

Can't we just fake this when the user press cancel?

Also we are technically limited to cancel the process so looks like we are stuck. We cannot "fake" the close of the session.

My idea is to present the message the process cannot be stopped while started. And inform not to close the session to prevent the process from being "lost". Not the best UX but the only solution in my point of view.

@kpyszkowski How much time it will take us to build a solution that will allow us to have a functional Cancel button? Again, hypothetically speaking.

Quite a long time. We rely on tBTC SDK and its needed to "rethink" all underlying processes to allow for redemption cancellation. I think @lukasz-zimnoch and @r-czajkowski can give more details on it.
Let's move the discussion to Discord thread.

@kpyszkowski was the discussion moved to Discord? If so, can you share the link to he thread?

FYI, this is related to #592 - when user requests withdrawal and dapp is assembling the transaction to sign and then user disconnects the dapp from the wallet, we log the user out, but the assembly is still going on. I don't think this can be as easily fixed as the case with the description of #603.
