bitcoin

This is the Bitcoin app for Vanadium. It is composed of the following crates:

• app contains the V-app.
• client contains the client of the V-app.
• common contains the code shared between the V-App and the client.

The client is a library crate (see lib.rs), but it also has a test executable (main.rs) to interact with the app from the command line.

Build the V-App

Risc-V

In order to build the app for the Risc-V target, enter the app folder and run:

cargo build --release --target=riscv32i-unknown-none-elf

Native

In order to build the app for the native target, enter the app folder and run:

cargo build --release --target=x86_64-unknown-linux-gnu

Run the V-App

Make sure you built the V-App for the Risc-V target.

Launch Vanadium on speculos. Then execute:

From the client folder

cargo run

If you want to run the V-app on a real device, execute instead:

cargo run -- --hid

If you want to run the V-app natively, after building it for the native target, use:

cargo run -- --native
