Retrieve ABI from sourcify / metadata

@chriseth thanks! This is a huge help. I'll make sure to prioritize this issue.

I'm not in Lisbon but @chriseth is there so you might bump into each other. I think it's more or less clear and seems to be quite parallel with what we want to build. I will be letting you know about the progress, thanks!

Basic support for sourcify got released in: https://github.com/dethcrypto/eth-sdk/releases/tag/%40dethcrypto%2Feth-sdk%400.2.2

Currently, it uses sourcify API (backend), we could migrate to IPFS once npm package is done and exposes a simple interface for us to use.

We were thinking about implementing this as an npm package ethereum/sourcify#538 This is also what you will need right? We might want to sync on this so we won't do the same thing separately.

The main goal was to return the decoded the parameters either using the ABI or the userdoc if available but an additional method that will return the ABI should be useful.

@kuzdogan yes definately! NPM package woudl be great. It's not top prority for us now but will gonna do it in a month or so. If you want some feedback from us, we can hop on a call or meet somewhere in Lisbon. Your call.

@krzkaczor we have an initial working package and would love to have some feedback if you'd have time and to better understand what you'd need 🙂 How should I contact you?

[krzkaczor]

@kuzdogan Perfect! I am @krzkaczor on telegram.

@hasparus did initial implementation in #42

@kuzdogan first big piece of feedback is that we need s CJS build instead of ESM. You should support both in your package IMO.

[kuzdogan]

Thanks, these are valuable feedback. I agree that they should both be available. We'll look into it.

Let me know if you have any other remarks, both on the package or Sourcify in general. @hasparus @krzkaczor
