nadohq/nado-contracts ? reverse-engineered prompt

Build me the Nado Protocol core smart contracts for the EVM.

I want a clean Solidity project that compiles and is set up the way a real contract repo should be, with the core Nado functionality organized under the core folder. Please make it easy to install dependencies and run the compile command from the project instructions, and keep the code clear enough that I can extend it later.

If anything is unclear from the existing repo, use the current docs or look up the latest best practices online before you guess. Make sure the contracts are structured sensibly, the project builds successfully, and any missing pieces needed for a basic working setup are filled in.
