---

Open Remix

• Open Remix at: https://remix.ethereum.org/

• Next, open the contracts folder and create a new file—in this case, demo.sol."

---

Write Your Contract

In Remix:

• Open the Solidity file (e.g., Demo.sol)

• Import the BLOCX-20 contract from an audited OpenZeppelin ERC-20 source, then set your variables, such as the name, minted amount, and other parameters. Screenshot Reference: Basic.png

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract Demo is ERC20 {
    constructor(address recipient) ERC20("demo", "demo") {
        _mint(recipient, 10000 * 10 ** decimals());
    }
}

---

Compile the Contract

• Go to the Solidity Compiler tab (🔨 icon).

• Select the correct compiler version (0.8.20).

• Hit "Compile Demo.sol" ✅.

---

Connect MetaMask (Injected Provider)

• Go to the Deploy & Run Transactions tab (Ethereum icon).

• Under ENVIRONMENT, choose Injected Provider - MetaMask ➤ This connects Remix to MetaMask's current network.

Screenshot Reference: Injected Provider - MetaMask, account shown.

Make sure MetaMask is connected to your target chain (e.g., BLOCX-Mainnet with ID 86996 as in screenshot).

---

Set Deployment Settings

• Set Value: Leave at 0 (unless the constructor needs BLOCX).

• Select Contract: Demo - Demo.sol

• In the DEPLOY section, enter the recipient address (who will receive the minted tokens).

Make sure it’s a valid BLOCX address (starts with 0x...).

---

Deploy

• Click Transact ➝ MetaMask popup appears.

• Review and Confirm the transaction.

Screenshot Reference: MetaMask deploy confirmation window with fee and data.

Wait for transaction confirmation on-chain ⛓️.

---

Interact with the Deployed Contract

After deployment:

• Under Deployed Contracts, expand your contract instance.

• You can now interact with:

  • balanceOf(address)

  • transfer(to, value)

  • approve, transferFrom

  • totalSupply, name, symbol, decimals

Screenshot Reference: Interaction UI with balanceOf, transfer, etc.

For example:

• Check balance with balanceOf(recipient)

• Transfer tokens using transfer(to, amount) with appropriate decimals.
