# Using the Rust Toolchain

For basic instructions on using the Rust to Valida compiler toolchain, see [QUICK START: Valida Compiler Toolchain](/lita-documentation/quick-start/valida-compiler-toolchain.md). This page covers more advanced usage instructions for the Rust to Valida toolchain.

## Keccak acceleration

The Valida VM has the capability of accelerated Keccak hash proving. To use this capability in Rust, you can simply import `sha3::Keccak256` and use the Keccak hasher in the `sha3` crate in the usual way. The `keccak-crate` example located at `/valida-toolchain/examples/rust/keccak-crate` exemplifies this usage. You must use Lita's forked version of the Keccak crate, using a line in your `Cargo.toml` such as:

```
[dependencies]
sha3 = { git = "https://github.com/lita-xyz/hashes", default-features = false }
```
