ZServed Smart Contract Specifications

Comprehensive smart contract architecture for ZServed’s DAO governance, treasury management, and stakeholder participation with professional legal oversight.

Smart Contract Architecture Overview

ZServed’s smart contract system provides decentralized governance capabilities while maintaining professional legal oversight and regulatory compliance through innovative hybrid governance mechanisms.

Core Contract System

Primary Smart Contracts:

  • ZServedToken: ERC-20 governance token with utility features
  • DAOGovernance: Governance contract with professional oversight integration
  • TreasuryManagement: Multi-signature treasury with fiduciary controls
  • StakeholderRewards: Automated reward distribution and staking mechanisms
  • ProfessionalOverlay: Legal professional oversight and compliance enforcement

ZServed Token Contract (ZSERVED)

1. Token Economics and Structure

ERC-20 Token Specification:

contract ZServedToken is ERC20, Ownable, Pausable {
    string public constant NAME = "ZServed DAO Token";
    string public constant SYMBOL = "ZSERVED";
    uint8 public constant DECIMALS = 18;
    uint256 public constant TOTAL_SUPPLY = 1_000_000_000 * 10**DECIMALS;


    // Token distribution allocations
    uint256 public constant COMMUNITY_ALLOCATION = 350_000_000 * 10**DECIMALS; // 35%
    uint256 public constant DEVELOPMENT_ALLOCATION = 250_000_000 * 10**DECIMALS; // 25%
    uint256 public constant COMPLIANCE_RESERVE = 200_000_000 * 10**DECIMALS; // 20%
    uint256 public constant TEAM_ALLOCATION = 150_000_000 * 10**DECIMALS; // 15%
    uint256 public constant TREASURY_RESERVE = 50_000_000 * 10**DECIMALS; // 5%
}

Token Utility Features:

  • Governance Voting: Token-weighted voting on platform governance proposals
  • Platform Access: Enhanced platform features and priority service access
  • Staking Rewards: Staking mechanisms providing additional governance weight
  • Professional Recognition: Enhanced professional recognition and network access

2. Vesting and Distribution

Vesting Schedule Implementation:

contract TokenVesting {
    struct VestingSchedule {
        uint256 totalAmount;
        uint256 cliff;
        uint256 start;
        uint256 duration;
        uint256 released;
        bool revocable;
    }


    mapping(address => VestingSchedule) public vestingSchedules;


    function createVestingSchedule(
        address beneficiary,
        uint256 amount,
        uint256 cliff,
        uint256 duration,
        bool revocable
    ) external onlyOwner {
        require(amount > 0, "Amount must be greater than 0");
        require(duration > 0, "Duration must be greater than 0");
        require(cliff <= duration, "Cliff cannot exceed duration");


        vestingSchedules[beneficiary] = VestingSchedule({
            totalAmount: amount,
            cliff: cliff,
            start: block.timestamp,
            duration: duration,
            released: 0,
            revocable: revocable
        });


        emit VestingScheduleCreated(beneficiary, amount, cliff, duration);
    }
}

Distribution Timeline:

  • Team Vesting: 4-year vesting with 1-year cliff
  • Community Rewards: 5-year distribution with performance incentives
  • Development Fund: 3-year allocation tied to platform milestones
  • Compliance Reserve: Emergency fund with professional oversight

DAO Governance Contract

1. Governance Mechanism

Proposal and Voting System:

contract DAOGovernance {
    struct Proposal {
        uint256 id;
        address proposer;
        string title;
        string description;
        uint256 startTime;
        uint256 endTime;
        uint256 forVotes;
        uint256 againstVotes;
        uint256 abstainVotes;
        bool executed;
        ProposalType proposalType;
    }


    enum ProposalType {
        STANDARD,           // Regular platform proposals
        CONSTITUTIONAL,     // Charter and governance changes
        EMERGENCY,         // Emergency decisions
        PROFESSIONAL       // Professional standards and compliance
    }


    mapping(uint256 => Proposal) public proposals;
    mapping(uint256 => mapping(address => bool)) public hasVoted;


    uint256 public constant STANDARD_QUORUM = 15; // 15% of total supply
    uint256 public constant CONSTITUTIONAL_QUORUM = 25; // 25% of total supply
    uint256 public constant EMERGENCY_QUORUM = 10; // 10% of total supply
}

Governance Process:

  1. Proposal Submission: Community members submit governance proposals
  2. Professional Review: Legal professionals review for compliance
  3. Community Discussion: 7-day discussion period for stakeholder input
  4. Voting Period: Token-weighted voting with appropriate quorum requirements
  5. Professional Oversight: Legal professional final review for compliance
  6. Execution: Approved proposals executed with professional oversight

2. Professional Oversight Integration

Legal Professional Veto Power:

contract ProfessionalOverlay {
    mapping(address => bool) public authorizedProfessionals;
    mapping(uint256 => bool) public professionalVetoed;


    modifier onlyAuthorizedProfessional() {
        require(authorizedProfessionals[msg.sender], "Not authorized professional");
        _;
    }


    function exerciseProfessionalVeto(
        uint256 proposalId,
        string memory reason
    ) external onlyAuthorizedProfessional {
        require(!professionalVetoed[proposalId], "Already vetoed");
        require(bytes(reason).length > 0, "Reason required");


        professionalVetoed[proposalId] = true;


        emit ProfessionalVetoExercised(proposalId, msg.sender, reason);
    }


    function addAuthorizedProfessional(address professional) external onlyOwner {
        require(professional != address(0), "Invalid address");
        authorizedProfessionals[professional] = true;
        emit ProfessionalAuthorized(professional);
    }
}

Professional Oversight Mechanisms:

  • Compliance Veto: Legal professionals can veto proposals violating professional standards
  • Emergency Override: Emergency powers for critical professional compliance issues
  • Advisory Recommendations: Professional advisory input on complex governance decisions
  • Ethics Enforcement: Enforcement of professional ethical standards and requirements

    uint256 public proposalCount;


    modifier onlyMultisig() {
        require(isValidSigner(msg.sender), "Not authorized signer");
        _;
    }


    function submitTreasuryProposal(
        address to,
        uint256 amount,
        bytes memory data,
        string memory description
    ) external onlyMultisig returns (uint256) {
        uint256 proposalId = proposalCount++;


        TreasuryProposal storage proposal = proposals[proposalId];
        proposal.id = proposalId;
        proposal.to = to;
        proposal.amount = amount;
        proposal.data = data;
        proposal.description = description;
        proposal.submissionTime = block.timestamp;


        emit TreasuryProposalSubmitted(proposalId, to, amount, description);
        return proposalId;
    }
}

2. Financial Controls and Compliance

Automated Financial Controls:

contract FinancialControls {
    uint256 public constant MAX_SINGLE_TRANSACTION = 1000000 * 10**18; // 1M tokens
    uint256 public constant DAILY_SPENDING_LIMIT = 5000000 * 10**18; // 5M tokens
    uint256 public constant EMERGENCY_RESERVE_MIN = 50000000 * 10**18; // 50M tokens


    mapping(uint256 => uint256) public dailySpending; // day => amount


    modifier financialControls(uint256 amount) {
        require(amount <= MAX_SINGLE_TRANSACTION, "Exceeds single transaction limit");


        uint256 today = block.timestamp / 1 days;
        require(
            dailySpending[today] + amount <= DAILY_SPENDING_LIMIT,
            "Exceeds daily spending limit"
        );


        require(
            address(this).balance - amount >= EMERGENCY_RESERVE_MIN,
            "Would breach emergency reserve minimum"
        );


        dailySpending[today] += amount;
        _;
    }


    function executeTreasuryTransfer(
        address to,
        uint256 amount
    ) external onlyApprovedProposal financialControls(amount) {
        // Execute transfer with automated controls
        payable(to).transfer(amount);
        emit TreasuryTransferExecuted(to, amount);
    }
}

Stakeholder Rewards Contract

        uint256[] memory amounts
    ) external onlyAuthorized {
        require(recipients.length == amounts.length, "Array length mismatch");


        RewardPool storage pool = rewardPools[poolName];
        uint256 totalDistribution = 0;


        for (uint256 i = 0; i < recipients.length; i++) {
            pool.userRewards[recipients[i]] += amounts[i];
            totalDistribution += amounts[i];
        }


        require(
            pool.distributedAmount + totalDistribution <= pool.totalAllocation,

        uint256 amount;
        uint256 stakingTime;
        uint256 lockupPeriod;
        uint256 multiplier;
    }


    mapping(address => StakeInfo) public stakes;
    mapping(address => uint256) public delegatedVotes;


    // Staking multipliers based on lockup period
    uint256 public constant BASE_MULTIPLIER = 100; // 1.0x
    uint256 public constant SIX_MONTH_MULTIPLIER = 125; // 1.25x
    uint256 public constant ONE_YEAR_MULTIPLIER = 150; // 1.5x
    uint256 public constant TWO_YEAR_MULTIPLIER = 200; // 2.0x


    function stakeTokens(uint256 amount, uint256 lockupPeriod) external {
        require(amount > 0, "Amount must be greater than 0");
        require(
            lockupPeriod == 0 || lockupPeriod == 180 days ||
            lockupPeriod == 365 days || lockupPeriod == 730 days,
            "Invalid lockup period"
        );


        uint256 multiplier = getStakingMultiplier(lockupPeriod);


        stakes[msg.sender] = StakeInfo({
            amount: amount,
            stakingTime: block.timestamp,
            lockupPeriod: lockupPeriod,
            multiplier: multiplier
        });


        // Transfer tokens to staking contract
        zservedToken.transferFrom(msg.sender, address(this), amount);


        emit TokensStaked(msg.sender, amount, lockupPeriod, multiplier);
    }


    function getVotingPower(address account) external view returns (uint256) {
        StakeInfo memory stake = stakes[account];
        uint256 baseVotes = zservedToken.balanceOf(account);
        uint256 stakedVotes = (stake.amount * stake.multiplier) / BASE_MULTIPLIER;
        uint256 delegated = delegatedVotes[account];


        return baseVotes + stakedVotes + delegated;
    }
}

1. Professional Standards Enforcement

Automated Compliance Monitoring:

contract ComplianceMonitoring {
    enum ComplianceStatus { COMPLIANT, WARNING, VIOLATION, SUSPENDED }


    struct ProfessionalProfile {
        bool isVerified;
        string jurisdiction;
        string barNumber;
        uint256 verificationDate;
        ComplianceStatus status;
        string[] specializations;
    }


    mapping(address => ProfessionalProfile) public professionalProfiles;
    mapping(address => bool) public suspendedAccounts;


    modifier onlyCompliantProfessional() {
        require(
            professionalProfiles[msg.sender].isVerified &&
            professionalProfiles[msg.sender].status == ComplianceStatus.COMPLIANT,
            "Professional compliance required"
        );
        _;
    }


    function verifyProfessional(
        address professional,
        string memory jurisdiction,
        string memory barNumber,
        string[] memory specializations
    ) external onlyAuthorized {
        professionalProfiles[professional] = ProfessionalProfile({
            isVerified: true,
            jurisdiction: jurisdiction,

        string decisionType;
        string justification;
        uint256 timestamp;
        bool clientInterestPriority;
        bool professionalStandardsCompliant;
    }


    mapping(uint256 => FiduciaryDecision) public fiduciaryDecisions;
    mapping(address => bool) public authorizedFiduciaries;


    modifier fiduciaryCompliant() {
        require(authorizedFiduciaries[msg.sender], "Not authorized fiduciary");
        _;

        fiduciaryDecisions[decisionId] = FiduciaryDecision({
            id: decisionId,
            fiduciary: msg.sender,
            decisionType: decisionType,
            justification: justification,
            timestamp: block.timestamp,
            clientInterestPriority: clientInterestPriority,
            professionalStandardsCompliant: true
        });


        emit FiduciaryDecisionRecorded(decisionId, msg.sender, decisionType);
    }
}

Security and Audit Framework

1. Security Mechanisms

Multi-Layer Security Implementation:

contract SecurityFramework {
    // Reentrancy protection
    uint256 private constant _NOT_ENTERED = 1;
    uint256 private constant _ENTERED = 2;
    uint256 private _status;


    modifier nonReentrant() {
        require(_status != _ENTERED, "ReentrancyGuard: reentrant call");
        _status = _ENTERED;
        _;
        _status = _NOT_ENTERED;
    }


    // Access control with time delays
    mapping(bytes32 => uint256) public pendingActions;
    uint256 public constant TIME_DELAY = 24 hours;


    function scheduleAction(bytes32 actionHash) external onlyAuthorized {
        pendingActions[actionHash] = block.timestamp + TIME_DELAY;
        emit ActionScheduled(actionHash, block.timestamp + TIME_DELAY);
    }


    function executeScheduledAction(bytes32 actionHash) external {
        require(
            pendingActions[actionHash] != 0 &&
            block.timestamp >= pendingActions[actionHash],
            "Action not ready for execution"
        );


        delete pendingActions[actionHash];
        // Execute action
    }
}

2. Audit and Monitoring

        uint256 id;
        address actor;
        string eventType;
        bytes32 resourceId;
        string action;
        bytes data;
        uint256 timestamp;
        bytes32 transactionHash;
    }


    mapping(uint256 => AuditEvent) public auditEvents;
    uint256 public auditEventCount;


    function logAuditEvent(
        string memory eventType,
        bytes32 resourceId,
        string memory action,
        bytes memory data
    ) internal {
        uint256 eventId = ++auditEventCount;


        auditEvents[eventId] = AuditEvent({
            id: eventId,
