Example ​

ts
import { createPublicClient, http } from 'viem'
import {publicActions, amountToNumber} from 'reverse-mirage'

export const publicClient = createPublicClient({
  chain: mainnet,
  transport: http()
}).extend(publicActions)

// read token metadata
const usdc = await publicClient.getERC20({
  address: '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48', // usdc
})

console.log(usdc.decimals) // 6

// read a balance
const vitalikBalance = await publicClient.getERC20Balance({
  erc20: usdc,
  address: '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045' // vitalik
})

console.log(amountToNumber(vitalikBalance)) // 420.69
