This doc will take you through the basics of creating a TronBox project and deploying a smart contract to a blockchain.

NOTE: Before you begin, it is advised that you read the TRON documentation.

TronBox Installation

Before using TronBox, please install it using npm command. You can install TronBox by referring to the installation instructions.

Create a project

Most of the TronBox commands are run under the directories of TronBox projects. So the first step is to create a TronBox project. You can create a bare project, but for those getting started, you can use TronBox Boxes, which offers example applications and project templates. We'll use the MetaCoin box, which creates a token that can be transferred between accounts.

Create a directory for MetaCoin:

mkdir MetaCoin
cd MetaCoin

Download ("unbox") the MetaCoin project:

tronbox unbox metacoin

You can create a bare project without smart contracts using tronbox init.

Once this operation is completed, you will have a project structure with the following items:

contracts/: Directory for Solidity contracts
migrations/: Directory for scriptable deployment files
test/: Directory for test files for testing your applications and contracts. For more information, refer to "How to test contracts?"
tronbox.js: TronBox configuration file

Explore the project

This page is just a quickstart, and we're going to get into the details in the following sections.

contracts/MetaCoin.sol: This is a smart contract (written in Solidity) that creates a MetaCoin token. Note that this also references another Solidity file contracts/ConvertLib.sol in the same directory.
contracts/Migrations.sol: This is a separate Solidity file used to manage and upgrade smart contracts. It is needed in every project and usually does not need to be edited.
migrations/1_initial_migration.js: This is the script used to deploy the Migrations contract, and is stored within the Migrations.sol file.
migrations/2_deploy_contracts.js: This is a deployment script that is used to deploy the MetaCoin contract. (Deployment scripts run in sequence. Scripts titled with 2 normally run after those titled 1.)
test/metacoin.js: This is a testing script written in JavaScript that ensures your contract is working as expected.
tronbox.js: This is the TronBox configuration file , for setting network information and other project-related settings. The file can be left blank because we can use a TronBox command that has some defaults built in.

Compile

Compile a smart contract:

tronbox compile

We will see the following output:

Compiling .\contracts\ConvertLib.sol...
Compiling .\contracts\MetaCoin.sol...
Compiling .\contracts\Migrations.sol...
 
Writing artifacts to .\build\contracts

Deploy with TronBox Runtime Environment (TRE)

To deploy our smart contracts, we're going to need to connect to a blockchain. TronBox has a built-in TRE private chain that can be used for testing. Please note that this blockchain is local to your system and does not interact with the main TRON network.
You can start this blockchain and interact with it using TronBox Runtime Environment. This step is to create a complete personal chain for development on TRON.

Pull images from the docker:

docker pull tronbox/tre

For how to install docker, please refer to docker installation documentation

1. Start the TronBox Runtime Environment and run the following commands:

docker run -it \
-p 9090:9090 \
--rm \
--name tron \
tronbox/tre

We will see the following information:

This shows ten accounts (and their private keys) that can be used when interacting with the blockchain.

This docker image is not optimized for the Apple ARM chip (Apple silicon), so it may be unusable and the docker needs to be restarted several times.

2. Open the console and execute the deployment:

tronbox migrate

We will see the following output:

This shows the network, addresses of your deployed contracts, and transaction statuses.

NOTE: Your transaction hashes and contract addresses will be different from the above.

Test

1.Open the console terminal and run the Solidity test instance

tronbox test ./test/metacoin.js

2.After hitting the return key, you will see the following output:

    Contract: MetaCoin
    ✓ should verify that there are at least three available accounts
    ✓ should verify that the contract has been deployed by accounts[0] (64ms)
    ✓ should put 10000 MetaCoin in the first account (116ms)
  Sleeping for 1 second... Slept.
    ✓ should call a function that depends on a linked library (1116ms)
    ✓ should send coins from account 0 to 3 and verify that a Transfer event has been emitted (1066ms)
  Sleeping for 3 seconds... Slept.
    ✓ should send coins from account 0 to 1 (1277ms)

If you’re on Windows and encountering problems running this command, please see the documentation on Solving naming conflicts on Windows.

Interact with the contract

To interact with the contract, you can use the tronbox console.

tronbox console

You will see the following prompt:

tronbox(development)>

The name in the parentheses of the prompt tronbox(development)> is the network that is currently connected to.

For example:

Check the account balance:

tronbox(development)> tronWeb.trx.getAccount()

//outputs:
//{
//  account_name: '5a696f6e',
//  address: '41928c9af0651632157ef27a2cf17ca72c575a4d21',
//  balance: 94999899999000000,
//  latest_opration_time: 1667357772000,
//  allowance: 140480000000,
//  is_witness: true,
//  account_resource: {}
//}

Obtain the list of accounts:

tronbox(development)> tronWeb._accounts
 
//output:
//[
//  'TPt8VDCU5c5PWsZ8KDTsq9YwQRoSFpN1KX',
//  'TPQbBa5TvHCjoJX3EWBtQ44Laq929wCuxb',
//  'TC5SR8sVePhmPvdusQoks3gaTv7aM523Rp',
//  'TWDvZhLq4cXPF4p9UsyJC3XVLqVGUVwxuj',
//  'TKrtFy3GYGZeoyT8wwbbpap3vuSXSKUq1w',
//  'TLKrFZtDNBcp9wAGnCfkY7nKoMdpeGvtkX',
//  'TKG9BwY5vySYoq6Wmw31c7tXz1q6sjcDC8',
//  'TPSBT6r6kwgMhwrzTYYKsJCrwQkkjQHxBA',
//  'TKu86RPU6Kr88kx6LNxofidA3HRKX5tUEj',
//  'TLpJz5qNiWh2VSkR1ynmVDL3nCFQ8J7euY'
//]

Call the contract to check the account balance:

tronbox(development)> MetaCoin.deployed().then(res => res.getBalance(tronWeb._accounts[0]))

//outputs:
//BigNumber { _hex: '0x2710', _isBigNumber: true }

Transfer some metacoin to other accounts:

tronbox(development)> MetaCoin.deployed().then(res => res.sendCoin(tronWeb._accounts[1],500))

//outputs:
//'3b6a2cb56841f5cd39b4e081c33465909204b36794fcd494c0374eb5d3d3fb9d'

Check the balance of the account that received the metacoin:

tronbox(development)> MetaCoin.deployed().then(res => res.getBalance(tronWeb._accounts[1]))

//outputs:
//BigNumber { _hex: '0x01f4', _isBigNumber: true }

Check the balance of the account that sent the metacoin:

tronbox(development)> MetaCoin.deployed().then(res => res.getBalance(tronWeb._accounts[0]))

//outputs:
//BigNumber { _hex: '0x251c', _isBigNumber: true }
