Release Notes

nomiclabs/hardhat (@​nomiclabs/hardhat-etherscan)

v3.1.8

Compare Source

v3.1.7: @​nomiclabs/hardhat-etherscan v3.1.7

Compare Source

This version of hardhat-etherscan improves how already verified contracts are handled. In previous versions, verification would be attempted and an error would be returned by the server. Starting from this version, the plugin will detect that the contract is already verified and show a message informing the user about this. Thanks @​OptimusOpus for working on this!

Besides that, this version adds support for Gnosis Chain's Chiado testnet.

v3.1.6

Changes

• 070abb7: Added support for the http_proxy environment variable. When this variable is set, hardhat-etherscan will use the given proxy to send the verification requests.

Compare Source

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)

v3.1.0: @​nomiclabs/hardhat-etherscan v3.1.0

Compare Source

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"
      }
    }
  ]
}

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