first contract deployment trial on zksync! oh, and there is one thing I wanna remind: when I try to deploy Greeter contract, it says that Request-Rate Exceeded, and estimated gas cost didn't pop up for a long time. So I commented the code bridging from Goerli to zksync and ran again, the contract just got deployed in a sec. I think this might be a problem you should remind in README file.
