Contract Address

The ERC-20 contract address for The Root Network native tokens uses the following format: 
0xCCCCCCCC[4-byte-token-id]000000000000000000000000
To make things easier, the @therootnetwork/evm provides a handy function to convert token asset ID to its equivalent contract address. 
import { assetIdToERC20Address } from "@therootnetwork/evm";

const ROOT_ASSET_ID = 1;
const ROOT_CONTRACT_ADDRESS = assetIdToERC20Address(ROOT_ASSET_ID);
