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: 34

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 version of the library installed. The check_bdk_version() utility function will throw a warning if your version of the library is not the one defined in the script.

pip3 install bdkpython
python 1.balance.py

Swift Scripts

The Swift scripts in this repository use the swift sh tool, which allows to integrate 3rd-party dependencies in scripts easily. You can install the tool using brew:

brew install swift-sh

From there, simply run the scripts using the following pattern on your command line:

swift sh 1.balance.swift
