Is it really that difficult to implement basic address validation? Instead of simply putting all the onus on the user to ensure everything is 100% correct, shouldn't (wouldn't?) a "professional" want to try to mitigate the risks and make things as easy and "safe" as possible for the end user?

Almost all decent services (mixers, exchanges, gambling sites etc) have some sort of basic address validation to prevent users from entering an "invalid" address. Note that this is a completely different scenario to a "wrong" address, which could be caused by copy/paste virus or the user copying from the wrong wallet etc. You can't easily protect against that. You can however easily stop a user entering "thisISMyBitcoinAddress" in a bitcoin address field!

However, I can type whatever I want in the box, "gfhfghjgffghgfhfghdh" and then when I try to mix I see:

So, it would seem that a user can't even double check that the address has been entered correctly before sending money. Is there a way that the user can do a last minute double check what address(es) the coins will be sent to before sending money? Or is it only after sending that they get a letter of guarantee etc?


Also, I'm not sure I would personally trust a business owner who conducts their business while high:

I don't have anything against recreational drug use, but it doesn't give me confidence that the business is being run in a professional manner. Much like Elon Musk smoking up. It's bad "optics". Best of luck with your mixing service, and I hope you consider some of the very good recommendations that have already been made. I like Eddie's idea of a signed receipt. Using a signed message from a publicly staked address that states the addresses entered would be good.
