Hi @madtechnologistproton , after reviewing the provided log, it appears that you are utilizing the @openzeppelin/hardhat-upgrades plugin for deploying smart contracts with proxy support. However, please note that this functionality is currently incompatible with zksync. Rest assured, our team is actively working on a plugin that will enable proxy functionality specifically for zksync. Although it is still under development, you may consider using it for testing purposes. Here is the link to the hardhat-zksync-upgradable package.
