Release Notes

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.

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.
