classDAO is a decentralized governance platform designed for classes, student groups, or organizations, where each member holds a unique NFT that represents their membership. Only NFT holders can propose and vote on decisions, ensuring secure, transparent, and exclusive governance.
A Decentralized Autonomous Organization (DAO) is a blockchain-powered entity that operates without centralized control. Decisions are made collectively by members, with rules and operations enforced by smart contracts.
Key DAO characteristics:
- Decentralized: No single authority; all members have voting rights.
- Autonomous: Smart contracts automatically execute decisions.
- Transparent: All transactions and votes are publicly visible.
NFT Membership: Each member holds a unique NFT granting governance rights. On-Chain Governance: Members submit proposals and vote directly on the blockchain. Smart Contract Automation: Voting results are executed without manual intervention. Whitelisted Access: Only NFT holders can interact with governance contracts. Transparency & Security: Immutable records ensure trust among members.
Several key smart contracts were built for classDAO to ensure decentralized governance and membership control: 1. Governance Contract This contract manages the decision-making process, proposal submissions, voting, and execution. Its key features include: Proposal Submission: Only NFT-holding members can submit proposals. Voting Mechanism: One NFT equals one vote, ensuring fairness and transparency. Execution of Proposals: Once consensus is reached, proposals are automatically executed by the contract. 2. Membership Contract (NFT) This contract mints an NFT for each DAO member, representing their membership. Key features include: NFT Minting: Each member receives a unique NFT minted to their wallet upon joining. Whitelisting Mechanism: Only wallets holding the classDAO NFT are allowed to interact with the governance contract, ensuring that only verified members can vote. Voting Access: Without the NFT, a wallet address cannot participate in governance activities, safeguarding exclusive membership participation.

When using the Remix IDE to work on classDAO’s smart contracts, the default workspace provides essential directories and files to streamline development:
contracts: Holds three smart contracts with increasing levels of complexity. scripts: Contains four TypeScript files to deploy contracts using web3.js or ethers.js libraries. tests: Includes Mocha-Chai unit tests for the contracts, allowing for comprehensive testing and debugging.
The scripts folder contains TypeScript files that deploy the "Storage" contract. To deploy other contracts, simply update the contract's name in the script (e.g., deploy_with_ethers.ts or deploy_with_web3.ts) and provide the necessary constructor arguments.
To run a script:
Right-click on the file in the File Explorer and select "Run." Ensure the Solidity file is already compiled, as the output from the script will appear in the Remix terminal.
