# [Cast](https://getfoundry.sh/cast)

Cast is a Swiss Army knife for interacting with Ethereum applications from the command line.
You can make smart contract calls, send transactions, or retrieve any type of chain data - all from your command-line!
The cast binary can be used both within and outside of a Foundry project.

```sh
npx --yes @foundry-rs/cast@nightly block-number
