Lesson 7 : Api Key error while verifying my contract on Goerli network

[LKG-LukeS]

I am getting this error:

NomicLabsHardhatPluginError: You are trying to verify a contract in 'goerli', but no API token was found for this network. Please provide one in your hardhat config. For example:

{
...
etherscan: {
apiKey: {
goerli: 'your API key'
}
}

This is my relevant code:

const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY || ""

module.exports = {
    defaultNetwork: "hardhat",
    networks: {
        hardhat: {
            chainId: 31337,
        },
        goerli: {
            url: GOERLI_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 5,
            blockConfirmations: 6,
        },
    },
    solidity: {
        compilers: [
            {
                version: "0.8.8",
            },
            {
                version: "0.6.6",
            },
        ],
    },
    etherscan: {
        apiKey: {
            goerli: ETHERSCAN_API_KEY,
        },

@NTLukeS Make sure to console log the ETHERSCAN_API_KEY and check it should not empty or undefined.

[LKG-LukeS]

Thanks for the reply! I logged the ETHERSCAN_API_KEY from the deploy script and it read out correctly as it shows in my etherscan account. Is there a way to log it from the hardhat.config.js file? That seems to be where it's running into a problem.

@NTLukeS
You may log it easily from hardhat.config.js file as well, just comment the irrelevant code and run the file using
node hardhat.config.js

[alymurtazamemon]

@NTLukeS just do console.log() and run any hardhat command.

Your private key should be in hexa-decimals, for example:

goerli: {
url: GOERLI_RPC_URL,
accounts: [0x{PRIVATE_KEY}],
chainId: 5,
blockConfirmations: 6,
},
