Simple development framework for Tron SunNetwork TronBox is a fork of Truffle code

TronBox Documentation


npm install -g sunbox

OS requirement

  • NodeJS 8.0+
  • Windows, Linux, or Mac OS X


Initialize a Customer Sun-Box Project
sunbox init

Download a dApp, ex: metacoin-box
sunbox unbox metacoin

Contract Compiler
sunbox compile

To compile for all contracts, select --compile-all.

Optionally, you can select:
--compile-all: Force compile all contracts.
--network save results to a specific host network


To use SunBox, your dApp has to have a file sunbox.js in the source root. This special files, tells SunBox how to connect to nodes and event server, and passes some special parameters, like the default private key. This is an example of sunbox.js:

module.exports = {
  networks: {
    development: {
// For trontools/quickstart docker image
      privateKey: 'da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0',
      userFeePercentage: 30,
      feeLimit: 100000000,
      mainFullHost: '',
      sideFullHost: '',
      mainGateway: 'TWaPZru6PR5VjgT4sJrrZ481Zgp3iJ8Rfo',
      sideGateway: 'TGKotco6YoULzbYisTBuP6DWXDjEgJSpYz',
      chainId: '41E209E4DE650F0150788E8EC5CAFA240A23EB8EB7',
      network_id: "*"
    mainnet: {
// Don't put your private key here, pass it using an env variable, like:
// PK=da146374a75310b9666e834ee4ad0866d6f4035967bfc76217c5a495fff9f0d0 tronbox migrate --network mainnet
      privateKey: process.env.PK,
      userFeePercentage: 30,
      feeLimit: 100000000,
      mainFullHost: '',
      sideFullHost: '',
      mainGateway: '',
      sideGateway: '',
      chainId: '',
      network_id: "*"

Notice that the example above uses Tron Quickstart >= 1.1.16, which exposes a mononode on port 9090.

Contract Migration

sunbox migrate

This command will invoke all migration scripts within the migrations directory. If your previous migration was successful, sunbox migrate will invoke a newly created migration. If there is no new migration script, this command will have no operational effect. Instead, you can use the option --reset to restart the migration script.

sunbox migrate --reset

Parameters by contract (introduced in v2.2.2)

It is very important to set the deploying parameters for any contract. In TronBox 2.2.2+ you can do it modifying the file


and specifying the parameters you need like in the following example:

var ConvertLib = artifacts.require("./ConvertLib.sol");
var MetaCoin = artifacts.require("./MetaCoin.sol");

module.exports = function(deployer) {
  deployer.deploy(ConvertLib);, MetaCoin);
  deployer.deploy(MetaCoin, 10000, {
    fee_limit: 1.1e8,
    userFeePercentage: 31,
    originEnergyLimit: 1.1e8

Start Console

This will use the default network to start a console. It will automatically connect to a TVM client. You can use --network to change this.

sunbox console

The console supports the sunbox command. For example, you can invoke migrate --reset in the console. The result is the same as invoking sunbox migrate --reset in the command.

Extra Features in TronBox console:

  1. All the compiled contracts can be used, just like in development & test, front-end code, or during script migration.

  2. After each command, your contract will be re-loaded. After invoking the migrate --reset command, you can immediately use the new address and binary.

  3. Every returned command's promise will automatically be logged. There is no need to use then(), which simplifies the command.


To carry out the test, run the following command:

tronbox test

You can also run the test for a specific file:

tronbox test ./path/to/test/file.js

Testing in TronBox is a bit different than in Truffle. Let's say we want to test the contract Metacoin (from the Metacoin Box that you can download with tronbox unbox metacoin):

contract MetaCoin {
	mapping (address => uint) balances;

	event Transfer(address _from, address _to, uint256 _value);
	event Log(string s);

	constructor() public {
		balances[tx.origin] = 10000;

	function sendCoin(address receiver, uint amount) public returns(bool sufficient) {
		if (balances[msg.sender] < amount) return false;
		balances[msg.sender] -= amount;
		balances[receiver] += amount;
		emit Transfer(msg.sender, receiver, amount);
		return true;

	function getBalanceInEth(address addr) public view returns(uint){
		return ConvertLib.convert(getBalance(addr),2);

	function getBalance(address addr) public view returns(uint) {
		return balances[addr];

Now, take a look at the first test in test/metacoin.js:

var MetaCoin = artifacts.require("./MetaCoin.sol");
contract('MetaCoin', function(accounts) {
  it("should put 10000 MetaCoin in the first account", function() {

    return MetaCoin.deployed().then(function(instance) {
    }).then(function(balance) {
      assert.equal(balance.toNumber(), 10000, "10000 wasn't in the first account");
  // ...

Starting from version 2.0.5, in TronBox artifacts () the following commands are equivalent:'getBalance', accounts[0]);

and you can pass the address and amount for the method in both the following ways:

instance.sendCoin(address, amount, {from: account[1]});


instance.sendCoin([address, amount], {from: account[1]});

How to contribute

  1. Fork this repo.

  2. Clone your forked repo recursively, to include submodules, for example:

git clone --recurse-submodules -j8
  1. If you use nvm for Node, please install Node 8, and install lerna globally:
nvm install v8.16.0
nvm use v8.16.0
npm i -g lerna
  1. Bootstrap the project:
lerna bootstrap
  1. During the development, for better debugging, you can run the unbuilt version of TronBox, for example
./ migrate --reset
