👩‍💻Smart Contract Code

Full description of smart contract functions and their duties in the contract

In this document, we will delve into the core features and functionalities of the LopeCoin smart contract. LopeCoin adheres to the ERC-20 token standard, ensuring compatibility with a wide range of decentralized applications (DApps) and wallets. We'll explore its token minting process, ownership and governance structure, liquidity pool management capabilities, redistribution mechanism, support for charitable causes, token locking functionality, and token burning capability.

By understanding these key aspects, you'll gain insight into how LopeCoin aims to provide a versatile and sustainable solution within the crypto ecosystem. Let's dive in and explore the intricacies of LopeCoin's smart contract!

ERC-20 Compatibility:

interface IERC20 {
    function totalSupply() external view returns (uint256);
    function balanceOf(address account) external view returns (uint256);
    function transfer(address recipient, uint256 amount) external returns (bool);
    function allowance(address owner, address spender) external view returns (uint256);
    function approve(address spender, uint256 amount) external returns (bool);
    function transferFrom(address sender, address recipient, uint256 amount) external returns (bool);
    event Transfer(address indexed from, address indexed to, uint256 value);
    event Approval(address indexed owner, address indexed spender, uint256 value);
}

interface IERC20Metadata is IERC20 {
    function name() external view returns (string memory);
    function symbol() external view returns (string memory);
    function decimals() external view returns (uint8);
}

Functionality:

• These interfaces define the standard functions and events required for ERC-20 compliant tokens.

• They ensure compatibility with various decentralized applications (DApps) and wallets by providing a standardized interface for interacting with the token contract.

Token Minting:

constructor() ERC20("LopeCoin", "LOPE") {
    _mint(msg.sender, 400 * 10**12 * 10**18); 
    _owner = msg.sender; 
}

Functionality:

• The constructor function initializes the LopeCoin token contract upon deployment.

• It mints the initial supply of LopeCoin tokens, creating 400 trillion tokens.

• The deployer of the contract becomes the owner.

Ownership and Governance:

address private _owner;

modifier onlyOwner() {
    require(msg.sender == _owner, "Caller is not the owner");
    _;
}

Functionality:

• The _owner variable stores the address of the contract owner.

• The onlyOwner modifier restricts access to functions to only the owner.

• It provides the owner with the authority to manage key contract parameters and functionalities.

Liquidity Pool Management:

uint256 public liquidityPoolPercentage;
uint256 public redistributionPercentage;
address public liquidityPoolAddress;

function setLiquidityPoolAddress(address _liquidityPoolAddress) external onlyOwner {
    require(_liquidityPoolAddress != address(0), "Invalid address");
    liquidityPoolAddress = _liquidityPoolAddress;
}

function setLiquidityPoolPercentage(uint256 _percentage) external onlyOwner {
    require(_percentage <= 100, "Percentage must be <= 100");
    liquidityPoolPercentage = _percentage;
}

Functionality:

• These functions manage the liquidity pool associated with LopeCoin.

• setLiquidityPoolAddress allows the owner to set the address of the liquidity pool.

• setLiquidityPoolPercentage allows the owner to set the percentage of transaction fees allocated to the liquidity pool.

Redistribution Mechanism:

function setRedistributionPercentage(uint256 _percentage) external onlyOwner {
    require(_percentage <= 100, "Percentage must be <= 100");
    redistributionPercentage = _percentage;
}

Functionality:

• This function allows the owner to set the percentage of transaction fees redistributed to token holders.

• It enables redistribution of a portion of transaction fees to token holders, incentivizing holding.

Charity Support:

struct CharityWallet {
    address wallet;
    uint256 percentage;
}

CharityWallet[] public charityWallets;

function addMultipleCharityWallets(address[] memory wallets, uint256[] memory percentages) public onlyOwner {
    require(wallets.length == percentages.length, "Wallets and percentages array must be of the same length");

    for (uint i = 0; i < wallets.length; i++) {
        require(wallets[i] != address(0), "Invalid charity wallet address");
        require(percentages[i] > 0 && percentages[i] <= 100, "Invalid percentage");
        charityWallets.push(CharityWallet(wallets[i], percentages[i]));
    }
}

Functionality:

• The CharityWallet struct represents a charity wallet address and the percentage of transaction fees allocated to it.

• addMultipleCharityWallets allows the owner to add multiple charity wallets and specify the percentage of transaction fees allocated to each.

• It integrates a unique charity support feature, enabling token holders to contribute to predefined charity wallets.

Token Locking:

struct Lock {
    uint256 amount;
    uint256 unlockTime;
}

mapping(address => Lock[]) private _locks;

function lockTokens(uint256 amount, uint256 unlockTime) external {
    require(msg.sender == _owner || msg.sender == liquidityPoolAddress, "Not authorized");
    require(amount <= balanceOf(msg.sender), "Insufficient balance");
    require(unlockTime > block.timestamp, "Unlock time must be in the future");

    _locks[msg.sender].push(Lock({
        amount: amount,
        unlockTime: unlockTime
    }));

    emit Transfer(msg.sender, address(this), amount);
}

function getLockedTokens(address account) public view returns (uint256 totalLocked) {
    totalLocked = 0;
    for (uint i = 0; i < _locks[account].length; i++) {
        if (_locks[account][i].unlockTime > block.timestamp) {
            totalLocked += _locks[account][i].amount;
        }
    }
}

Functionality:

• The Lock struct represents a token lock, storing the locked amount and unlock time.

• lockTokens allows stakeholders to lock tokens for a specified period, restricting their transferability until the unlock time.

• getLockedTokens retrieves the total amount of tokens locked by an account.

Token Burning:

function burn(uint256 amount) public {
    if (_msgSender() == _owner || _msgSender() == liquidityPoolAddress) {
        bool tokensAreLocked = false;

        for (uint i = 0; i < _locks[_msgSender()].length; i++) {
            if (_locks[_msgSender()][i].amount > 0 && _locks[_msgSender()][i].unlockTime > block.timestamp) {
                tokensAreLocked = true;
                break; 
            }
        }

        require(!tokensAreLocked, "Tokens are locked");

        uint256 lockedAmount = 0;
        for (uint i = 0; i < _locks[_msgSender()].length; i++) {
            if (_locks[_msgSender()][i].unlockTime > block.timestamp) {
                lockedAmount += _locks[_msgSender()][

i].amount;
            }
        }

        require(balanceOf(_msgSender()) - lockedAmount >= amount, "Amount exceeds available balance");
    } else {
        require(balanceOf(_msgSender()) >= amount, "Amount exceeds available balance");
    }

    _burn(_msgSender(), amount);
}

Functionality:

• burn allows token holders to permanently remove tokens from circulation by burning them.

• It includes checks to ensure that tokens are not burned if they are locked or if the sender does not have sufficient balance.

• Burning tokens helps reduce the total token supply, potentially increasing the value of remaining tokens.

These functions collectively provide key features and functionalities to the LopeCoin smart contract, enhancing its utility and governance capabilities.
