Building a DAO Governance Platform: Voting, Treasury, and Proposal Management

DAO governance platforms enable decentralized decision-making through proposals, voting, and treasury management.

Governance Data Model

interface Proposal {
  id: string; title: string; description: string; proposer: string
  status: 'pending' | 'active' | 'passed' | 'executed' | 'rejected'
  forVotes: bigint; againstVotes: bigint; endTime: number
}

interface DAOTreasury {
  totalValueUsd: number
  assets: Array<{ token: string; balance: number; valueUsd: number }>
}

Token-Weighted Voting

contract Governor {
    IERC20 public governanceToken;
    function castVote(uint256 proposalId, uint8 support) external {
        uint256 weight = governanceToken.balanceOf(msg.sender);
        votes[proposalId][support] += weight;
        emit VoteCast(msg.sender, proposalId, support, weight);
    }
}

Treasury Dashboard

Display holdings, recent transactions, and governance statistics with charts and real-time updates.

The Bottom Line

The DAO Governance App from BreafIO provides proposal creation, voting, and treasury management. The Token Launchpad creates governance tokens. The Multi-Sig Wallet UI adds treasury security. The Blockchain Explorer tracks governance transactions, and the Web3 Auth Kit handles wallet authentication.
