Add Ethereum checksum casing support #36

Closed notlesh closed 7 months ago

notlesh commented 1 year ago

Ethereum addresses can be expressed with a built-in checksum that uses mixed capital- and non-capital-case hex letters to provide a checksum of the address. This is meant to help prevent typos which might lead to lost funds.

Some code was copied from Moonbeam along with a TODO mentioning that this should be added, context:

More details on the technique: https://coincodex.com/article/2078/ethereum-address-checksum-explained/

This issue is a task to include support for this, and could be a great learning exercise for a curious mind. Bonus points: this could also potentially be added to Moonbeam itself, although I would suggest starting with a solution for this repo :)

This issue is relevant to the code on the UCB tag.

But the evm contracts features will be removed for the next wave, so I'll close this for now.
