Writing apps for hardware signing devices is about to get this easy
```
#![cfg_attr(target_arch = "riscv32", no_std, no_main)]
extern crate alloc;
use alloc::vec::Vec;
sdk::bootstrap!();
fn process_message(_app: &mut sdk::App, msg: &[u8]) -> Vec {
msg.to_vec()
}
pub fn main() {
sdk::App::new(process_message).run();
Sounds good to me

Anything you'd like to build?
Not yet, I am just dipping my toes at the moment. I just read the architecture of the Coldcard and started to dive a bit more 😀
