 - [cosmwasm-std](https://docs.rs/cosmwasm-std/latest/cosmwasm_std/) - Crate that is a standard
   library for smart contracts. It provides essential utilities for communication with the outside
   world, helper functions, and types. Every smart contract we will build will use this dependency.

-  later in the book.
 - [schemars](https://docs.rs/schemars/latest/schemars/index.html) - Crate used to create JSON schema
   documents for our contracts. It is automatically derived on types generated by ^sylvia and will be
   later used to provide concise API for blockchain users, who might not be Rust developers.
