Contract interaction from Typescript

The installation process of this application takes care of creating the static typing files and factory required for Typescript to interact with the ERC-20 ABI. The types are created using TypeChain in the postinstallation step, from the JSON ABI file, and the output files are stored in the path src/types/contracts.

⚠️ The typing files and factory required to interact with the Polygon Hermez contracts ABIs may be created by uncommenting the related section in the script src/generate-contract-types.sh and running npm run generate-contract-types or npm i.

Once the typing files are built, you can instantiate a typed contract using its factory as follows:

import { Erc20__factory } from "src/types/contracts/erc-20/factories/Erc20__factory";
const contract = Erc20__factory.connect(ethereumAddress, provider);
