Key Components

1. HonorCoin (ERC-20 Token)

The philanthropic token that powers both initiatives:

  • Automatic Fee: 7.77% of every transfer goes to the treasury
  • Transparent: All fees tracked on-chain
  • Flexible: Configurable exemptions for contracts
// Example: Transfer with automatic fee
honorCoin.transfer(recipient, amount);
// 7.77% automatically sent to treasury

2. Shield of Honor™ Treasury

Manages the ethical support fund:

  • Milestone-Based: Funds released when milestones are reached
  • Automated: Chainlink Automation triggers disbursements
  • Transparent: Complete audit trail via events and NFTs
  • Secure: Role-based access control
// Create a milestone
treasury.createMilestone(
    "Community Support Program",
    targetAmount,      // e.g., 10,000 HONOR
    disbursementAmount, // e.g., 8,000 HONOR
    beneficiaryAddress
);

// Chainlink Automation automatically completes when target reached

3. NFT Staking & Governance

Rewards NFT holders with governance rights:

  • Stake NFTs: Earn HonorCoin rewards
  • Vote: Participate in governance decisions
  • Transparent: Voting power based on stake duration
// Stake an NFT
staking.stakeNFT(tokenId);

// Vote on proposals
staking.vote(proposalId, true); // true = support

4. OmniGambling NFT Marketplace

NFT marketplace with charitable integration:

  • Trade NFTs: Buy and sell with HonorCoin
  • Donate: Optional donations on purchases
  • Track: All donations recorded as NFTs
  • Support: Multiple charitable causes
// Purchase with donation
marketplace.purchaseNFT(
    nftContract,
    tokenId,
    donationAmount, // Optional donation
    causeId        // Which cause to support
);

Testing

Comprehensive test suite with 45+ test cases:

# Run all tests
npm test

# Run with coverage
npm run test:coverage

# Run specific test file
npx hardhat test test/HonorCoin.test.js

Deployment

Local Development

# Start local Hardhat network
npx hardhat node

# Deploy to local network
npx hardhat run scripts/deploy.js --network localhost

Testnet Deployment

# Deploy to Sepolia testnet
npx hardhat run scripts/deploy.js --network sepolia

# Deploy to Mumbai testnet (Polygon)
npx hardhat run scripts/deploy.js --network mumbai

Mainnet Deployment

  1. Update hardhat.config.js with mainnet RPC URLs
  2. Ensure sufficient ETH/MATIC for gas fees
  3. Run deployment script with mainnet network
  4. Verify contracts on Etherscan/Polygonscan

See docs/DEPLOYMENT_GUIDE.md for detailed instructions.

Security Features

  • ✅ Access Control: Role-based permissions (Admin, Manager, Auditor)
  • ✅ Reentrancy Protection: All sensitive functions protected
  • ✅ Input Validation: Comprehensive checks on all inputs
  • ✅ Safe Math: Solidity 0.8.x overflow protection
  • ✅ Audit Trail: All actions logged with events
  • ✅ Fee Limits: Maximum fee caps to prevent abuse

Workflow Integration

GitHub Actions

Automated testing runs on every push:

  • Compiles all contracts
  • Runs complete test suite
  • Generates coverage reports
  • Security checks (when available)

Next Steps

  1. Deploy to Testnet: Test contracts in a live environment
  2. Set Up Chainlink Automation: Register upkeeps for automated disbursements
  3. Create Charitable Causes: Add causes to the marketplace
  4. Define Milestones: Set up initial treasury milestones
  5. Frontend Development: Build dApp for user interaction
  6. Security Audit: Professional audit before mainnet deployment
