Readme

This repo hosts a collection of scripts that make use of the Bitcoin Development Kit and some of its language bindings.

Total number of scripts: 14

Rust Scripts

To run Rust scripts, you'll the need the rust-script tool installed. From there, simply use

rust-script 1.balance.rs

Kotlin Scripts

You can call Kotlin scripts directly like so:

kotlin 1.balance.main.kts

To use a dependency that only exists in your local Maven repository, add the path to your local Maven at the top of the file like so:

@file:Repository("file:///~/.m2/repository/")
@file:DependsOn("org.bitcoindevkit:bdk-jvm:0.27.0-SNAPSHOT")

import org.bitcoindevkit.*

// ...

Python Scripts

Python is easy! Just make sure you have the correct packages installed.

pip3 install bdkpython
python 1.balance.py
