A complete DAO (Decentralized Autonomous Organization) implementation built with Solidity, Hardhat, and React. This project demonstrates governance mechanisms, certificate management, and voting systems on the blockchain.

This DAO consists of:

• GovToken (GT): ERC20 governance token with voting capabilities
• MyGovernor: OpenZeppelin-based governor contract for proposal management
• TimeLock: Time-delayed execution controller for security
• Certificate (Cert): Certificate management system controlled by the DAO

• Symbol: GT
• Type: ERC20 + ERC20Permit + ERC20Votes
• Features: Governance voting, delegation, minting (owner only)
• Initial Supply: 1,000 GT tokens

• Voting Period: 45818 blocks (~1 week)
• Voting Delay: 7200 blocks (~1 day)
• Quorum: 4% of total supply
• Features: Proposal creation, voting, execution via TimeLock

• Min Delay: 0 seconds (configurable)
• Purpose: Secure execution of governance proposals
• Roles: Proposer, Executor, Admin

• Purpose: Certificate management system
• Owner: TimeLock contract (DAO-controlled)
• Features: Issue and manage certificates

1. Token Distribution: Deploy GovToken and distribute to stakeholders
2. Delegation: Token holders delegate voting power to themselves or others
3. Proposal Creation: Create proposals to modify the Certificate contract
4. Voting Period: Community votes on proposals
5. Execution: Successful proposals are executed via TimeLock

The test suite covers:

• Token deployment and delegation
• Proposal creation and voting
• TimeLock execution
• Certificate management
• Full governance workflow

Run tests with detailed logs:

npx hardhat test --verbose

The UI folder contains a Vite + React application with:

• Material-UI components
• Web3 integration
• DAO interaction interface

npm install @mui/material @mui/icons-material @emotion/styled @emotion/react

• TimeLock Controller: Prevents immediate execution of proposals
• Quorum Requirements: Ensures minimum participation
• Voting Delays: Allows time for community review
• Role-based Access: Secure permission management

• Localhost: Local Hardhat node
• Sepolia: Ethereum testnet
• Hardhat: Built-in test network

See hardhat.config.js for network settings and compiler configuration.
