Validate Ethereum addresses in input fields

[raucao]

Adds address validation to the address inputs.

Importing the function from web3-utils, because ethers.js doesn't have any such utility function. :slightly_frowning_face:

ethers has that getchcksumaddress function that does some check: https://github.com/ethers-io/ethers.js/blob/061b0eae1d4c570aedd9bee1971afa43fcdae1a6/src.ts/utils/address.ts#L22

I guess that duplication of isValidAccount can not be prevented as we need that method in both files?

That's not a check, that's actually creating a checksum address from a non-checksum one.

It can, but that would be way more complex and require more code than the de-duplication is worth. In essence, isAddress is what's already de-duplicated here, and using it on this or that property is just a declarative action.

Good to merge.
