Part 1 : Add TRC20 as a Payment Method Using Node.js and React.js

Implementing a payment system using smart contracts on the TRON network can provide additional security and transparency, and can be achieved by following these general steps:

I assume you know all about the requirements and installations needed, so I will continue this article to the following step which is all about how to implement the payment system using smart contracts and so on.

1 - Using Smart contract:


Install TronBox: Simple Development Framework for Tronweb,

Also, it is good to know about:

What is the TronWeb? TronWeb is a library that allows you to interact with TronNetwork.

What is the TronNetwork? TRON is a decentralized, blockchain-based operating system with smart contract functionality, proof-of-stake principles as its consensus algorithm, and a cryptocurrency native to the system, known as Tronix (TRX).

Defining a smart contract involves writing the code that will handle the payment process and any other necessary functions. To define a smart contract for a payment system on the TRON network, we can use Solidity, a programming language that is used to write smart contracts on the TRON network. 

We need to install the TronBox in a separate folder in the project

npm install -g tronbox

Initialize a Tron-Box Project or you can just copy and paste the next step codes
tronbox init

To Initialize the TronWeb project we should use Bash terminal to compile our project.

You should have the exact same result as above image.

Install dotenv

npm install dotenv

install tronweb

npm install tronweb

To achieve online cryptocurrency based on TRC20 network payment goal we need to follow up on these 5 items:

1- Define the smart contract: You'll need to define the smart contract code that will handle the payment process. This will typically involve creating functions to accept payments, validate transactions, and trigger any necessary actions (such as updating an order status or sending a confirmation email).

2- Compile the smart contract: Once the code is written, you'll need to compile it into bytecode that can be deployed on the TRON network. This can be done using a compiler such as TronBox or Remix.

3- Deploy the smart contract: Once the smart contract is compiled, you'll need to deploy it to the TRON network. This can be done using a tool such as TronWeb or Truffle, which provide an API for interacting with the TRON network.

4- Integrate the smart contract: Once the smart contract is deployed, you'll need to integrate it into your website or app. This can be done by providing a user interface that interacts with the smart contract functions, and by configuring the system to use the smart contract for payment processing.

5- Monitor the smart contract: You'll need to monitor the smart contract for incoming transactions and validate that payments are being processed correctly. This can be done using tools such as TronScan or TronGrid.

1 - Define the smart contract:

From this point, we need to add up our TronLink account (Wallet) private key

Best practice to save critical information for all node projects is .env file, so we will save our private key into this file.

Create a .env file in your project root folder (it must be gitignored) and it should contain something like the following codes:



You can have your PRIVATE_KEY from your wallet configs.

To get your ETHERSCAN_API_KEY you need to sign up on and then get your developer API key.

After gathering these keys you can go for the next step.

In this step we will check our project folders and files, after successfully Initializing of TronWeb project it will download some unnecessary files and folders and you can do your research on them to get more familiar with these files.

In the Contracts folder you can create your PaymentContract.sol, sol is and extension for Solidty language.

And then in your PaymentContract.sol file you need to add this smart contract that can handle payments:
