bitcoind4j

Introduction

This Java-lib provides you with the basic fuctions for a bitcoin-wallet like deposit and withdrawal.
It also provides you with some more advanged functions like multisig.

Architecture

I found that native bitcoin-implementations like bitcoinj are not always stable. Therefore I choose to depend on the official bitcoind application. This application has a json-rpc interface.

The interaction with this interface is done via the command-pattern Command-pattern To hide the complexity of the native bitcoind json-rpc interface there is a Wallet class. This object has simple functions like withdraw and createAddress.

To make sure the Wallet is only configured once it can only be constructed via a builder Builder-pattern.

Example

URL endpoint = new URL("localhost:8333");
String username = "username";
String password = "password";
Wallet wallet = new Wallet.WalletBuilder(endpoint, username, password).build();

wallet.withdraw(0.25, "1JDd889QQSTDw5PfPtTxmczrn54R8gkCuG");
