# ERC-20 Token Contract

A minimal, standard-compliant ERC-20 fungible token implementation in Solidity.

A minimal, standard-compliant ERC-20 fungible token implementation in Solidity.

## Explanation

This contract inherits from OpenZeppelin's `ERC20` implementation, which handles all standard token logic (transfers, allowances, balances).

**Key points:**

* The constructor mints `initialSupply` tokens to the deployer.
* `decimals()` defaults to 18 (standard for ERC-20).
* Using OpenZeppelin means the contract is audited and standard-compliant.

Deploy with a constructor argument for the initial supply, e.g. `1000000` for one million tokens.

## Code

```solidity theme={null}
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

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

contract MyToken is ERC20 {
    constructor(uint256 initialSupply) ERC20("MyToken", "MTK") {
        _mint(msg.sender, initialSupply * 10 ** decimals());
    }
}
```
