Sui4j is a robust, reactive, type safe Java library for working with Smart Contracts on the @MystenLabs/sui network.

This allows you to work with the @MystenLabs/sui blockchain, without the additional overhead of having to write your own integration code for the platform in JVM ecosystem.

WARNING: Note that we are still iterating on the RPC and SDK API before TestNet, therefore please expect frequent breaking changes in the short-term. We expect the API to stabilize after the upcoming TestNet launch.

The latest 0.4.1 version tested with sui devnet-0.24.0 version.

To get started you need to install JDK8+, then run the following command:

$ ./gradlew build

For the latest javadocs for the main branch, run ./gradlew javadoc and open the document under the build/docs/javadoc/index.html in your browser.

./gradlew test

You can start sui local network refer to sui-local-network doc.

git clone [email protected]:MystenLabs/sui.git
cd sui
cargo build --release
