How to Create and Deploy a Smart Contract on Tron Network?

This article will look at how to deploy Tron ​​smart contract. We will talk about what Tron is, whether TRX has a future, and the blockchain in general.

Currently, many successful decentralized applications are based on this blockchain, and now is the best time to deploy a dApp on the Tron blockchain. This article will discuss how we can use the TRON blockchain as a virtual machine.

Tron Smart Contract Development Process

# Get the IDE

To make sure you have completed the prerequisites, please visit this site. Next, go to the Tron-IDE link to check the conditions:

Prerequisites:

• Google Chrome browser
• Having a TronLink Wallet. Search for the corresponding extension in the Google Chrome app store to get it. Next, it needs to be set up for the correct network (Shasta Testnet for testing purposes), and this will require a few TRX dollars, which are available for free on Testnet.

Once all prerequisites are met, go to this site. Done. You have an IDE.

# Create the Solidity Script

Now we need to create a new file. For example, let’s just call it Test.sol

pragma solidity >=0.7.0 <0.9.0;

// this is to write a test. whenever someone wants to add a line, he can call addLine.
// added text can never be removed
contract Test {
    string public text;

    // retrieve the current status of the test
    function get() public view returns (string) {
        return text;
    }

    // add text to the test
    function addLine(added_text) public {
        text = text + added_text;
    }
}

# Code Compile

After that, you need to go to the “Plugin Manager” and activate the “Solidity Compiler”. The compiler will be added as a new item in the menu and the list of active modules. Next, go to the “Solidity Compiler” module and click “Compile”. However, at this point, your smart contract code may throw errors.

# Resolve issues

One of the possible problems can be related to the warning about the license ID, as well as the error about the missing ID:

DeclarationError: Identifier not found or not unique.
--> browser/Test.sol:14:22:
|
14 | function addLine(added_text) public {

Other than that, a fix is required at the place where String was defined as a return parameter.

Although Solidity doesn’t offer the ability to concatenate two strings, there is one solution as a workaround. It is associated with the use of a special encodePacked function.

Thus, to fix all the errors that have arisen, we will fix the code:

// SPDX-License-Identifier: GPL-3.0

pragma solidity >=0.7.0 <0.9.0;

// this is to write a test. whenever someone wants to add a line, he can call addLine.
// added text can never be removed
contract Test {
    string public text;

    // retrieve the current status of the test
    function get() public view returns (string memory) {
        return text;
    }

    // add text to the test
    function addLine(string memory added_text) public {
        text = string(abi.encodePacked(text,added_text));
    }
}

As we can see, all errors are resolved, and recompilation is successful.

# Deploy Tron Smart Contract

You can now return to the Plugin Manager to activate the DEPLOYMENT plugin. Finally, the deployment plugin is active.

You need to open the “Tronlink wallet Google Chrome app extension” and select “TRON Shasta Testnet” from the dropdown at the top. You can now start deploying by using the appropriate button in the IDE’s deployment plugin. Please note that you must have enough test TRX tokens on your balance. You can request test tokens on the website: https://www.trongrid.io/shasta/. Also, take care to use a different wallet address than your TronGrid mainnet wallet address.

Congratulations! You have completed a successful deployment using the smart contract file.

A little bit about TRON

Like the Ethereum Virtual Machine (EVM), TRON is a turing complete machine. Tron aims to provide blockchain developers with a purpose-built blockchain system that is efficient, user-friendly, stable, secure, and scalable. TRON Studio is an IDE for developing, deploying, and debugging smart contracts based on Tron. It uses gRPC to register accounts and run smart contracts. However, there is currently no HTTP gateway support.
