Smart Contracts

Decentralized Infrastructure for the CashKey Ecosystem

Smart contract system designed to enable decentralized operation of the CashKey ecosystem with transparent and secure token economics.

📋 Contract Architecture

1. CKY Token Contract (ERC-20)

contract CKYToken is ERC20, Ownable {
    uint256 public constant TOTAL_SUPPLY = 10_000_000_000 * 10**18;
    
    mapping(address => uint256) public stakingBalance;
    mapping(address => uint256) public stakingTimestamp;
    
    function stake(uint256 amount) external;
    function unstake(uint256 amount) external;
    function calculateRewards(address user) external view returns (uint256);
}

2. Governance Contract

contract CashKeyGovernance {
    struct Proposal {
        string description;
        uint256 votesFor;
        uint256 votesAgainst;
        uint256 deadline;
        bool executed;
    }
    
    mapping(uint256 => Proposal) public proposals;
    mapping(address => mapping(uint256 => bool)) public hasVoted;
    
    function createProposal(string memory description) external;
    function vote(uint256 proposalId, bool support) external;
    function executeProposal(uint256 proposalId) external;
}

3. Rewards Distribution Contract

contract RewardsDistribution {
    mapping(address => uint256) public pendingRewards;
    mapping(address => uint256) public totalEarned;
    
    function distributeRewards(address[] memory users, uint256[] memory amounts) external onlyAuthorized;
    function claimRewards() external;
    function setRewardRate(uint256 newRate) external onlyGovernance;
}
