Multi-Tier DAO Treasury

Quadratic Voting & Dynamic Quorum Capital Allocation

01 / Context

The engineering problem.

Whale token holders routinely dominate flat token governance, allowing malicious actors to pass single-transaction treasury drains with low voter turnout.

Overview

A governance protocol designed to govern institutional treasury assets. Replaces naive 1-token-1-vote systems with square-root quadratic voting algorithms and tiered expenditure thresholds to safeguard DAO funds against hostile governance takeovers.

Governance Tiers: 3 Tiers
Voting Model: Quadratic (√n)
Timelock Range: 0 - 48 Hours

02 / System design

Tiered Proposal Controller & Quadratic Tally Engine

Routes expenditure proposals to different validation pipelines based on fund request magnitude.

Architecture / Governance / DeFi Infrastructure

[01]

Tier 1 (Small Grants): Low quorum, 3-day vote duration, instant execution upon passage.

Tier 2 (Medium Expenditures): 20% quorum, 7-day vote duration, 24-hour timelock execution queue.

Tier 3 (Large Capital Allocations): 40% quorum, 14-day vote duration, quadratic voting tally, and multi-sig emergency veto window.

03 / Adversarial defense

Technical challenges & mitigations.

Gas-Efficient Integer Square Root on EVM

Implemented the Babylonian square root method in assembly to compute quadratic voting weights with minimal gas overhead.

Vote Sybil Resistance Within Smart Contracts

Coupled voter registration with snapshot block balance verifications, preventing flash-borrowing tokens immediately before proposal creation.

04 / Implementation

Key features.

01Multi-tiered spending governance (Small, Medium, Major capital allocations)
02Quadratic voting calculation engine mitigating plutocratic dominance
03Timelocked execution queues allowing community intervention on suspicious votes
04Foundry fuzz testing suite confirming invariant solvency across vote outcomes
