Smart Contract Security / Upgradeability
A production-grade, three-tier upgradeable smart contract system implementing UUPS V1-V3 implementations with secure storage layouts, yield calculations, and delayed timelocked withdrawals.
05Multi-Tier DAO Treasury
Governance / DeFi Infrastructure
A decentralized governance system featuring square-root weighted (anti-whale) quadratic voting power and dynamic spending policies where quorums and voting periods scale with requested funds.
