Creating Your First Smart Contract on TON Blockchain: A Step-by-Step Guide

Creating your first smart contract on the TON (The Open Network) Blockchain involves several steps. Here's a step-by-step guide to help you get started:

Step 1: Set Up Your Development Environment

• Install Node.js: Make sure you have Node.js installed. You can download it from Node.js website.
• Install TON CLI: The TON CLI (Command Line Interface) is essential for interacting with the TON Blockchain. Install it using:

npm install -g tondev        

• Initialize TONDEV: Run the following command to initialize TONDEV:

tondev start        

Step 2: Create a Smart Contract Template

• Create a Project Directory: Create a new directory for your project and navigate into it:

mkdir ton-smart-contract
cd ton-smart-contract        

• Generate a New Project: Use TONDEV to generate a new project template:

tondev sol create contract        

This will create a new Solidity contract template in your directory.

Step 3: Write Your Smart Contract

• Edit the Contract: Open the contract.sol file generated in the previous step. Here is a simple example of a smart contract that stores a value:

pragma solidity >= 0.6.0;

contract SimpleStorage {
    uint256 storedData;

    function set(uint256 x) public {
        storedData = x;
    }

    function get() public view returns (uint256) {
        return storedData;
    }
}        

Step 4: Compile Your Smart Contract

• Compile the Contract: Use TONDEV to compile your smart contract

tondev sol compile contract.sol        

This will generate ABI and TVC files needed for deployment.

Step 5: Deploy Your Smart Contract

• Create a Wallet: Before deploying, you need a TON wallet. If you don't have one, you can create one using TONCLI:

tondev contract deploy Wallet        

• Deploy the Contract: Deploy your smart contract using the TON CLI:

tondev contract deploy contract --abi ./SimpleStorage.abi.json --tvc ./SimpleStorage.tvc        

Step 6: Interact with Your Smart Contract

• Set a Value: Call the set function to store a value in your contract:

tondev contract run contract set --abi ./SimpleStorage.abi.json --input '{"x": 12}'        

• Get the Value: Retrieve the stored value by calling the get function:

tondev contract run-local contract get --abi ./SimpleStorage.abi.json        

Step 7: Verify the Deployment

• Check the Status: Use the TON Explorer or CLI commands to verify that your smart contract is deployed and working as expected.

Step 8: Further Steps

• Explore: Continue exploring TON Blockchain capabilities by creating more complex contracts, integrating with front-end applications, and learning about advanced TON features.

By following these steps, you will have successfully created, deployed, and interacted with your first smart contract on the TON Blockchain.

Happy coding !
