@energyweb/iam-contracts

Overview

This package consists of EVM smart contracts related to EnergyWeb IAM.

Usage

DomainReader

The DomainReader class can be used as shown to read a domain definition.

import {
  DomainReader,
  VOLTA_ENS_REGISTRY_ADDRESS,
} from "@energyweb/iam-contracts";
import { providers, utils } from "ethers";

(async () => {
  const provider = new providers.JsonRpcProvider(
    "https://volta-rpc.energyweb.org"
  );
  const reader = new DomainReader({
    ensRegistryAddress: VOLTA_ENS_REGISTRY_ADDRESS,
    provider,
  });
  const roleDefinition = await reader.read({
    node: utils.namehash("manufacturer.roles.flex.apps.exampleco.iam.ewc"),
  });
})();

Contract Descriptions

RoleDefinitionResolver.sol

This is an implementation of an ENS resolver that represents a role definition. It extends the ENS Public Resolver with additional resolver profiles, specifically for the use case of issuing and verify role claims using a smart contract. In other words, this custom ENS resolver allows some properties of a role definition to be (usefully) readable by another smart contract.

Development

Install dependencies:

$ npm install

Compile contracts, generate contract types and compile typescript:

$ npm run build

Run tests:

$ npm test

Debugging Tests

In vs code, the tests (which are run using Mocha), can be debugged with the following launch.json config. Before debugging the tests, start a local chain using npm run ganache.
