[dependabot]

Bumps @nomiclabs/hardhat-etherscan from 2.0.1 to 3.1.2.

Release notes

Sourced from @​nomiclabs/hardhat-etherscan's releases.

@​nomiclabs/hardhat-etherscan v3.1.2

• Added Arbitrum Goerli to the list of supported networks.
• Fixed an issue with the URLs used for Optimism Goerli.

@​nomiclabs/hardhat-etherscan v3.1.1

This version makes two changes to the networks supported by default:

• A new gnosis network was added, that works as an alias for xdai (thanks @​alebanzas!)
• The deprecated Optimism Kovan network was removed in favor of the Optimism Goerli network (thanks @​shanefontaine)

@​nomiclabs/hardhat-etherscan v3.1.0

This release adds support for verifying contracts in chains that are not included by default in hardhat-etherscan.

To do this, you add the network you want to verify in the customChains entry of the Etherscan configuration:

etherscan: {
  apiKey: {
    customNetwork: "<custom-network-api-key>"
  },
  customChains: [
    {
      network: "customNetwork",
      chainId: 12345,
      urls: {
        apiURL: "https://api-custom-network.etherscan.io/api",
        browserURL: "https://custom-network.etherscan.io"
      }
    }
  ]
}

You can read more about this here.
