Use eth-sdk for abi management

[krzkaczor]

eth-sdk is a tool that given a set of addresses (for example in json file) will download ABIs (from etherscan or sourcify) and generate a ready to use ethers.js contract instances with types generated with TypeChain.

It could serve as a replacement to the whole /contracts directory that is generated by CEA.

Example

{
  "contracts": {
    "mainnet": {
      "dai": "0x6b175474e89094c44da98b954eedeac495271d0f"
    },
  },
}

then simply run eth-sdk. This will get ABIs if they are not already acquired and will generate an SDK right into node_modules.

Then you can use it as:

import { getMainnetSdk } from '@dethcrypto/eth-sdk-client' // yay, our SDK! It's tailored especially for our needs
import { ethers } from 'ethers'

const mainnetProvider = ethers.getDefaultProvider('mainnet')
const defaultSigner = ethers.Wallet.createRandom().connect(mainnetProvider)

const sdk = getMainnetSdk(defaultSigner) // default signer will be wired with all contract instances
// sdk is an object like { dai: DaiContract }

// sdk.dai is fully typed, you get type completion inside your IDE
const balance = await sdk.dai.balanceOf(defaultSigner.address)
