[dependabot]

Bumps @nomiclabs/hardhat-etherscan from 2.0.1 to 3.1.0.

Release notes

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

@​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.

Thanks to @​no2chem for the initial implementation and to @​calvinaco who helped test this.

@​nomiclabs/hardhat-etherscan v3.0.4

This release adds support for verifying contracts in the Sepolia testnet (thanks @​pcaversaccio!)

@​nomiclabs/hardhat-etherscan v3.0.3

This is a small patch release fixing an error introduced in v3.0.2

Changelog

• Added Content-Type header to hardhat-etherscan's request for verifying contracts, in order to fix #2437.

@​nomiclabs/hardhat-etherscan v3.0.1

This release adds support for the Moonbeam network.

hardhat-etherscan v3.0.0

This new major version includes one of our most requested features: the possibility to specify multiple API keys for the hardhat-etherscan plugin (#1448).

You can learn more here, but the bottom line is that you can now do this in your config:

etherscan: {
  apiKey: {
      mainnet: etherscanApiKey,
      rinkeby: etherscanApiKey,
</tr></table>
