})

export const wagmiAbi = [
  ...
  {
    inputs: [{ name: "x", type: "uint32" }],
    stateMutability: "nonpayable",
    type: "constructor",
  },
  ...
] as const;

import { createWalletClient, custom } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { mainnet } from 'viem/chains'

export const walletClient = createWalletClient({
  chain: mainnet,
  transport: custom(window.ethereum)
})

// JSON-RPC Account
export const [account] = await walletClient.getAddresses()
// Local Account
export const account = privateKeyToAccount(...)
