Trident - TRON Java SDK

Overview

Trident is a lightweight Java SDK for interacting with the TRON blockchain. It provides a simple and efficient way to integrate TRON functionality into your Java applications.

Trident includes three main modules:

Module Description
core Wrapping functions for easily interacting with TRON system and smart contracts
abi Datatypes and ABI encoders/decoders
utils Tools including encryption, conversion, etc.

Features

  • Complete implementation of TRON's gRPC interfaces, with TLS support
  • Wallet key management and address utilities
  • Transaction building, signing and multi-sign
  • Smart contract deployment and interaction
  • ABI v2 support: structs, nested arrays and packed encoding
  • TRC10/TRC20/TRC721 token support

Install

Trident can be built with JDK 1.8 or JDK17 on Gradle 8.5. The latest version (built with JDK 1.8) can be found on Maven Central.

Upgrading to 1.0.0

Version 1.0.0 includes behavioral and dependency changes — see the 1.0.0 release notes before upgrading.

Version 0.9.2 and Later

Gradle

implementation("io.github.tronprotocol:trident:1.0.0")

Maven

<dependency>
    <groupId>io.github.tronprotocol</groupId>
    <artifactId>trident</artifactId>
    <version>1.0.0</version> 
</dependency>

Previous Versions (< 0.9.2)

For versions before 0.9.2, you'll need to build from source:

  1. Clone the repository from GitHub
  2. Build the project with required versions:
    • Java: 1.8.0_231
    • Gradle: 5.6.4
  3. Configure your project dependencies:
dependencies {
    // protobuf & grpc
    implementation 'com.google.protobuf:protobuf-java:3.11.0'

    implementation 'io.grpc:grpc-netty-shaded:1.31.0'
    implementation 'io.grpc:grpc-netty:1.31.0'
    implementation 'io.grpc:grpc-protobuf:1.31.0'
    implementation 'io.grpc:grpc-stub:1.31.0'

    implementation "org.bouncycastle:bcprov-jdk15on:1.68"

    implementation fileTree(dir:'../core')
    implementation fileTree(dir:'../utils')
    implementation fileTree(dir:'../abi')
    //if you are using the *.jar files, ues the following line
    implementation fileTree(dir:'your path', include: '*.jar')

    implementation 'com.google.guava:guava:28.0-jre'
}

Version Notice

We strongly recommend using version 0.9.2 or later, as newer versions are more stable and feature-rich, with all modules combined into a single package.

Integrity Check

Starting from version 0.9.2, releases are published to Maven repository and signed with the GPG key:

pub: 3149 FCA5 6377 2D11 2624 9C36 CC3F 8CEA 7B0C 74D6
