CPFP feature or removing "transaction fee is more than twice the sent amount"

[GRbit]

Description

Hi dear Wasabi devs! You are doing a great job supporting fast and reliable open source desktop wallet. Many KUDOS to you!

I'm here to ask you to do me and many other users a favor. I know there is closed issue #6579 , but IMHO it's a shame that there is NO WAY to pay fee greater than a transaction amount.

Reasoning

My usecase: I want to bump my transaction with CPFP technique, but I can't do this effectively because of this limitation. I could pay 3000 sat fee transferring only 1 sat, but I have to pay 6001 sat to bump it. Not a huge money after all, but I think you can agree that it feels very stupid to do so. I'm paying twice the money!

BTW: I have to bump my transaction, because by default Wasabi interface doesn't allow me to set fee manually. At the moment wasabi estimated network, transaction fee were lower than at the moment I was sending the money. As a result my transaction was delayed for more than a 24 hours instead of being done in 20 minutes. That was a shitty experience.

I know that you are trying to stop user from spending 123BTC for 0.00001BTC transaction, but I think it's just too harsh for any sane person to leave no choice at all. It could be a settings option, a hidden config file change, some captcha asking to solve the integral equation, literally anything, but there is nothing.

Designs

I think it would be just fine to have a setting parameter (as well as with custom fee). If you want more — config file line which will only be mentioned in documentation. If you desperately want not to allow this for any transaction, please, at least set some "sane" limit for this restriction. For example, if you spent less than 1$ as a fee you can still sent as less as 1 sat. At worse case you lose just one buck. Isn't it sane enough? And as a result you will have a cool CPFP feature in your wallet.

Thanks for your time!

I'm not exactly sure about the feature you're mentioning, but just as a quick FYI: Next release of Wasabi, which will be shipped in the following weeks, will include right click on a pending transaction -> Speed Up or Cancel. So basically features to CPFP and RBF.

@turbolay that sounds awesome! I didn't know that. If that feature is already on it's way, than it completely covers my use case. If you are sure that we will see such feature soon, I think the issues should be closed.
