Practical overview

When it fits

Use Solana4J when a Java application needs Solana transaction encoding, supported core-program functionality, or JSON-RPC communication.

Who it is for

  • Java developers building applications that read from or write to Solana.
  • Teams integrating Solana transaction encoding or RPC communication into Java services and tools.

Documented uses

  • Encode Solana Legacy or V0 transactions in Java.
  • Build Java integrations that communicate with Solana through supported JSON-RPC endpoints.
  • Work with supported Solana core programs from a Java application.
Before you choose

Requirements & limits

The public repository specifies an Apache-2.0 license. Local development requirements listed in the README include JDK 11 and Docker for Testcontainers.

  • The core library and companion JSON-RPC client serve different purposes; select the component or components matching the integration task.
  • The JSON-RPC client lists Jackson Databind, Jackson Annotations and Jackson Core as dependencies.
  • The README identifies integration tests as living documentation for supported programs and endpoints.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up a local solana4j development environment

Prepare the documented prerequisites for local development on solana4j.

Before you start

  • JDK 11
  • Docker for testcontainers

Steps

  1. Install JDK 11.

  2. Install Docker for testcontainers.

  3. On an M1, M2, M3, or M4 Mac, consult the repository’s shared/test-support/resources/README.md.

Expected outcome

The documented local development prerequisites are prepared.

Guide limitations

  • These steps cover environment prerequisites only; they do not document building the project or running tests.
  • Apple Silicon Mac-specific guidance is in the linked README.
