A Java library for building applications on Libra
The API for creating transactions and querying the database of Libra uses json-rpc - a simple remote procedure call protocol utilizing JSON for encoding data. Sending new transactions to the Libra network requires also another type of serialization - the Libra Canonical Serialization. JLibra implements both of these and provides a simple api for Java applications to integrate to Libra.
JLibra simplifies integration to Libra but does not hide any features of the Libra api, this makes it possible to implement anything supported by Libra with Java.
- JDK 8+
- Maven 3+
- Clone this repo
- Build project with
mvn install(this is important because the project contains classes that will be created during the Maven build and simply checking the project out is not enough)
Start sample Main classes in dev.jlibra.example package for examples (for a complete example with creating accounts to moving coins between them check the how to)

Versions of JLibra are deployed to the Central Maven repository, you can add JLibra as a dependency to your project:
Maven:
<dependency>
<groupId>dev.jlibra</groupId>
<artifactId>jlibra-core</artifactId>
<version>0.9.0</version>
</dependency>Gradle:
compile("dev.jlibra:jlibra-core:0.9.0")
