Read more about Hardhat Ignition I've been trying to get the arguments of an event that was emitted from a contract function call. getCode(addr) to make sure the code is actually deployed? I'm a three months old programmer. based on what i've found something like this should work: Events are very, very important for smart contracts and blockchain.
