Do you know how to validate wallet signature sent from ethers/web3 signed message?

In Javascript libraries there is this helper:

recoverPersonalSignature

That takes in a nonce and the signature and validates it returning the address. Is there a library that does this in Elixir?

So sorry about the delay. I finally added it to Hex. You should now be able to just include it and use it. I am hoping myself or someone will add TypedSignature next!

Nice! I implemented Personal ec_recover (web3.eth.personal — web3.js 1.0.0 documentation ) which I was going to share to github once I got my act together (I went lower level than exw3). If you want it, just let me know. I started working on typed message 3 and 4 but did not complete it and would love to get this done if there are co-collaborators.

Hoping to make Elixir into a great web3 language :slight_smile:
