[EPIC] Implement EIP-55 - Address Validity Checksum

[goranjovic]

Problem

Users should be protected against accidental typos in Ethereum addresses

https://eips.ethereum.org/EIPS/eip-55

Implementation

All screens that expose addresses should render it in mixed case according to eip-55 All inputs that accept addresses should display a warning if the entered address is not in mixed case or if it is not valid according to eip-55

Update: Warning screen UI Warning copy should read Error in address.

Future Steps

Steps which should be taken after this issue has been resolved.

[rachelhamlin]

All inputs that accept addresses should display a warning if the entered address is not in mixed case or if it is not valid according to eip-55

Do we re-use this error pop-up for invalid address for this case? @goranjovic @denis-sharypin

[denis-sharypin]

@rachelhamlin not, really. In the new design, it should be like this. But I can't come up with the good wording for that. "This address is not checksummed" sounds too technical for me.

[rachelhamlin]

Could simply say Error in address?

[goranjovic]

Maybe take a look and see how other wallets did it? It makes sense to be consistent in wording.

There are three cases:

• address is checksummed and the checksum is correct, it's A OK and nothing should happen
• address is not checksummed i.e. all letters are lowercase, there should be a warning but user should be able to continue. That's the case when user is say copying the address from an app that does not implement checksums, i.e. legacy mode
• address is checksummed, but incorrectly. There should be an error then, not a mere warning. The most likely use case is a typo or error in copying, which is the exact thing checksumming is supposed to prevent.

[denis-sharypin]

I checked a few mobile wallets with not checksummed address and none of them checking addresses for that. I got this error once only on myetherwallet.com and the description was like "This address is not checksummed". But I find such description too technical, something that an average user won't get.

[rachelhamlin]

Thanks for researching, @denis-sharypin.

I suspect this error state is unlikely anyway. Most people will copy/paste an address.

That said, I suggest sticking to plain English with Error in address or even Check for typos.

[StatusSceptre]

Do we want this one as a bounty? Please 👍 the issue if this one is to be bountied @rachelhamlin; wasn't sure of the state of it with the current discussions.

[rachelhamlin]

@StatusSceptre yes, would be great to put a bounty on. I'll edit the issue to include warning screen and copy. Can we keep @goranjovic tagged in the issue so that he can answer any questions?

[StatusSceptre]

No problem @rachelhamlin

Work has been started.

These users each claimed they can complete the work by 10 months, 3 weeks from now. Please review their action plans below:

1) mestorlx has been approved to start work.

I will follow the guidelines here(https://eips.ethereum.org/EIPS/eip-55) to implement the method to validate signatures. Once its done I will add it to one field to test and validate. After there is agreement from Status it will be extended to the rest of the fields. Should take a couple of days.
