@NeoRusi Push your code to GitHub and leave a link here, I want to check it.

[NeoRusi]

@alymurtazamemon I have already uploaded the correct repo ( even yesterday ) could please have a look?)

[jaymgonzalez]

Hi @alymurtazamemon I'm facing the same issue with my repo. I found a way to verify the contract by downloading git@github.com:PatrickAlphaC/hardhat-fund-me-fcc.git, adding my .env and goerli network information to it and it worked, so not sure what is causing the problem but in Patrick's repo doesn't happen. 🤷🏽‍♂️

[jaymgonzalez]

It worked for me in my repo adding the following to hardhat.config.ts

 etherscan: {
    apiKey: {
      goerli: ETHERSCAN_API_KEY,
    },
    // In case the module can't find the rinkeby etherscan automatically
    customChains: [
      {
        network: 'goerli',
        chainId: 5,
        urls: {
          apiURL: 'https://api-goerli.etherscan.io/api',
          browserURL: 'https://goerli.etherscan.io',
        },
      },
    ],
  },

For a certain reason there is no changes with customChains array or without it

[NeoRusi]

I also gitcloned Patrics repo and it worked without any development chains

[IleneSalamu]

is it working ?
