hardhat-zksync-verify doesn't support verifying UUPS Proxy
nicholaspai opened this issue · 2 comments
I was able to deploy a UUPS proxy and implementation and upgrade the proxy to the implementation. In addition I've verified the implementation via hardhat verify. However, I'm unable to verify the proxy:
Error in plugin @nomiclabs/hardhat-etherscan: Trying to verify a contract in a network with chain id 280, but the plugin doesn't recognize it as a supported chain.
I wonder if this is because uupsUpgradeableProxy isn't explicitly listed here?
Hi @nicholaspai, our verify plugin supports UUPS proxy verification, but from the error you submitted it seems that you are not using @matterlabs/hardhat-zksync-verify plugin, but @nomiclabs/hardhat-etherscan instead.
Both of those are necessary to install, but in your hardhat.config file you should import hardhat-zksync-verify as explained here.
Let me know if we can help any further.
Ah I see this did work in the end once I switched the dep from nomiclabs/hardhat-etherscan to nomicfoundation/hardhat-verify
