Holocoin Smart Contract

Overview

Holocoin is an ERC-20 compliant token built on the Ethereum blockchain. This smart contract defines a custom token named "SANKCOIN" with the abbreviation "SANK." The contract includes functionalities for minting and burning tokens, as well as keeping track of token balances for each address.

Features

1. Public Variables:

   • name: Stores the name of the token ("SANKCOIN").
   • abbrv: Stores the abbreviation of the token ("SANK").
   • supply: Stores the total supply of the token.

2. Mapping:

   • balances: Maps each address to its token balance.

3. Mint Function:

   • The mint function allows new tokens to be created and assigned to a specified address. It takes two parameters:
     • _address: The address to which the new tokens will be added.
     • _value: The amount of new tokens to be created.

4. Burn Function:

   • The burn function allows tokens to be destroyed from a specified address. It takes two parameters:
     • _address: The address from which the tokens will be deducted.
     • _value: The amount of tokens to be burned.
   • The function includes a check to ensure the address has enough tokens to burn the specified amount.

Smart Contract Code

// SPDX-License-Identifier: MIT
pragma solidity 0.8.18;

contract Holocoin {

    // Public variables
    string public name = "SANKCOIN";
    string public abbrv = "SANK";
    uint public supply = 0;

    // Mapping variable
    mapping(address => uint) public balances;

    // Mint function
    function mint(address _address, uint _value) public {
        supply += _value;
        balances[_address] += _value;
    }

    // Burn function
    function burn(address _address, uint _value) public {
        if (balances[_address] >= _value) {
            supply -= _value;
            balances[_address] -= _value;
        }
    }
}

Functions

Mint Function

function mint(address _address, uint _value) public {
    supply += _value;
    balances[_address] += _value;
}

• Description: Creates new tokens and assigns them to the specified address.
• Parameters:
  • _address: The address receiving the new tokens.
  • _value: The number of tokens to mint.

Burn Function

function burn(address _address, uint _value) public {
    if (balances[_address] >= _value) {
        supply -= _value;
        balances[_address] -= _value;
    }
}

• Description: Destroys tokens from the specified address, reducing the total supply.
• Parameters:
  • _address: The address from which tokens will be burned.
  • _value: The number of tokens to burn.
• Condition: Ensures that the address has enough tokens to burn.

Deployment

To deploy the Holocoin smart contract, follow these steps:

1. Install a development environment like Remix IDE or Truffle.
2. Copy the contract code into a new Solidity file (e.g., Holocoin.sol).
3. Compile the contract using the Solidity compiler.
4. Deploy the contract to the Ethereum network using your preferred method (Remix, Truffle, or other deployment tools).
