# Technical breakdown

## Technical breakdown

Start.cooking smart contract are built with CosmWasm and is currently deployed on:

* Osmosis
* Injective

### What is CosmWasm?[​](https://docs.daodao.zone/introduction/technical-breakdown#what-is-cosmwasm) <a href="#what-is-rust" id="what-is-rust"></a>

CosmWasm is a [WebAssembly](https://webassembly.org/) virtual machine that runs in a [Cosmos SDK](https://docs.cosmos.network/) module.

In practice, CosmWasm smart contracts (like Start.Cooking's) are written in Rust.

### What is Rust?[​](https://docs.daodao.zone/introduction/technical-breakdown#what-is-rust)

[Rust](https://www.rust-lang.org/) is a performant, memory-safe, and thread-safe programming language with a rich type system.

Writing smart contracts in Rust allows us to perform better security analysis on our contracts, which in turn protects your DAOs from common attacks.

### What about the UI?[​](https://docs.daodao.zone/introduction/technical-breakdown#what-about-the-ui) <a href="#what-about-the-ui" id="what-about-the-ui"></a>

Start.cooking UI is built with Typescript and Next JS.

As the UI is the primary entrypoint for users interacting with Start.cooking memes, its security is as important as the smart contracts themselves. We made sure increases the likelihood that bugs are detected earlier, during development.
