DAO Governance Smart Contract Development: From Token Voting to Multi-Sig

DAOs are the organizational backbone of Web3. Here's how to build governance systems that actually work.
Governance Models
Token-Weighted Voting - One token = one vote - Simple to implement, prone to plutocracy - Used by: Uniswap, Compound, Aave
Quadratic Voting - Cost of votes increases quadratically - More democratic, requires identity verification - Used by: Gitcoin, Optimism
Multi-Sig - Fixed set of signers with threshold - Fast execution, less decentralized - Used by: Gnosis Safe, most protocol treasuries
Conviction Voting - Votes accumulate over time - Favors long-term community members - Used by: 1Hive, Gardens
Smart Contract Architecture
A production DAO needs: 1. Governor Contract — proposal creation, voting, and execution 2. Timelock — delay between vote passing and execution (24-48 hours) 3. Token Contract — ERC-20 with vote delegation (ERC-20Votes) 4. Treasury — multi-sig or governor-controlled funds
Development Costs
- Basic DAO (token voting + multi-sig): $25,000-50,000
- Advanced DAO (quadratic voting + delegation): $60,000-120,000
- Enterprise DAO (custom governance + compliance): $100,000-200,000
TelGates has built governance systems for protocols managing over $50M in treasury assets.
