coldcard is a library for interfacing with the Coldcard hardware wallet.
```rust use coldcard::protocol;
// detect all connected Coldcards let serials = coldcard::detect()?;
// open a particular one let (mut coldcard, master_xpub) = serials[0].open(None)?;
// set a passphrase coldcard.set_passphrase(protocol::Passphrase::new("secret")?)?;
// after the user confirms let xpub = coldcard.getpassphrasedone()?;
if let Some(xpub) = xpub { println!("The new XPUB is: {}", xpub); }
// secure logout coldcard.logout()?; ```
This project also offers a CLI tool. See the project's own crate for more information.
Install it with:
bash
$ cargo install coldcard-cli
