Deploy Smart Contract on Tetreum

• Configure Remix IDE for Tetreum deployment
• Understand gas costs on Tetreum POA network
• Deploy and verify your contract
• Interact with deployed contracts

• MetaMask connected to Tetreum testnet
• Test TET tokens in your wallet
• Basic understanding of Solidity

Start by opening Remix IDE in your browser:

Create a new file and write your smart contract:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract TetreumDemo {
    string public message;
    address public owner;
    uint256 public deployTime;
    
    event MessageUpdated(string newMessage, address updatedBy);
    
    constructor(string memory _initialMessage) {
        message = _initialMessage;
        owner = msg.sender;
        deployTime = block.timestamp;
    }
    
    function updateMessage(string memory _newMessage) public {
        message = _newMessage;
        emit MessageUpdated(_newMessage, msg.sender);
    }
    
    function getContractInfo() public view returns (
        string memory _message,
        address _owner,
        uint256 _deployTime
    ) {
        return (message, owner, deployTime);
    }
}

1. Go to the "Solidity Compiler" tab
2. Select compiler version 0.8.0 or higher
3. Click "Compile TetreumDemo.sol"
4. Ensure compilation is successful with no errors

Set up deployment configuration:

1. Go to "Deploy & Run Transactions" tab
2. Set Environment to "Injected Provider - MetaMask"
3. Ensure MetaMask is connected to Tetreum testnet
4. Select your contract from the dropdown
5. Enter constructor parameters if needed

1. Click the "Deploy" button
2. Confirm the transaction in MetaMask
3. Wait for deployment confirmation (~3-10 seconds on POA)
4. Copy the contract address from Remix

Verify your contract for transparency:

1. Go to Tetreum Explorer
2. Search for your contract address
3. Click "Verify & Publish" on the contract page
4. Upload your source code and compilation settings
