I saw that Foundry has a CLI tool called Cast. What is it useful for?

1 Answer 1


Cast is a tool part of Foundry, the blazing fast, portable and modular toolkit for Ethereum application development.

To quote the README:

Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.

Cast has lots of helpful utilities for Ethereum developers. For instance, there is a command for querying the ETH balance of an account:

cast balance 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
# prints 34011798284984006579

And there is a command for getting a wei value from a simple number:

cast --to-wei 15
# prints 15000000000000000000
