ts
import { type EtherscanConfig } from '@wagmi/cli/plugins'apiKey

export default defineConfig({
  plugins: [
    etherscan({
      apiKey: process.env.ETHERSCAN_API_KEY, 
      chainId: 1,
      contracts: [
        {
          name: 'Wagmigotchi',
          address: '0xecb504d39723b0be0e3a9aa33d646642d1051ee1',
        },

      ],
    }),
  ],
})chainId 
number
