coldcard is a library for interfacing with the Coldcard hardware wallet.
```rust use coldcard::protocol;
// create an API instance let mut api = coldcard::Api::new()?;
// detect all connected Coldcards let serials = api.detect()?;
// open a particular one let (mut cc, masterxpub) = serials.intoiter().next().unwrap().open(&api, 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()?; ```
In order to be able to detect a Coldcard device on a Linux system, 51-coinkite.rules must be placed in /etc/udev/rules.d/.
Two mutually exclusive HID backends are supported and can be turned on using the following features:
linux-static-hidraw (default)linux-static-libusb (potential issues with unclear error messages)The log feature enables logging using the log crate. Disabled by default. Use judiciously as logging can leak details into the environment.
This project also offers a CLI tool. See the project's own crate for more information.
Install it with:
bash
$ cargo install coldcard-cli
