The good news is that all the tooling you have used in the development of Ethereum, or any other EVM-based blockchain for that matter, will work seamlessly with Zenith Chain. You get the blazing fast speed of Zenith without needing to switch from your favourite development environment, be it truffle or hardhat. Wallets (like Metamask), will also work and you will not have any sort of learning curve to start developing on Zenith.
