A protocol-level governance infrastructure designed to model how real decentralized organizations operate under long-term control.
Sentinel DAO is not a demo or a UI-driven product. It is a rigorous governance framework capable of controlling
treasury assets, protocol upgrades, and system parameters through enforced execution rules.

⚠️ Disclaimer
Sentinel DAO reflects protocol engineering rather than simple application development. It addresses real governance failure modes, long-term maintainability, and security isolation.
- No Implicit Power: The architecture follows a strict separation of power. No contract has implicit power over another, and no privileged role can bypass governance execution.
- Enforced Delays: All successful proposals execute exclusively through a Timelock Controller. This creates a transparent delay window, ensuring no governance decision is applied instantly.
- Governance as Infrastructure: This system is designed to be extended, audited, and integrated. It serves as the "Operating System" for an organization, not just a voting booth.
The system is anchored by a Hybrid Governor. While it leverages OpenZeppelin's battle-tested foundation, I engineered it to be strictly modular. Unlike monolithic DAOs, here the Voting Logic, Execution, and Treasury Control are isolated into separate components. This ensures that complex voting strategies cannot accidentally bypass treasury security boundaries.

The codebase is organized into logical domains, strictly separating Kernel Logic from Pluggable Modules. This ensures that governance strategies can evolve without destabilizing the core treasury or security layers.

CRYPTOGRAPHIC PRIMITIVES
Low-level helpers for signature verification and data formatting
- Hybrid Governor: Voting strategies are not hardcoded. Proposals can be executed under token-weighted, quadratic, or conviction-based models.
- Timelock Controller: Acts as the final source of truth. Funds cannot be moved and upgrades cannot happen without passing through the Timelock delay.
- Role Manager: Permissions are not scattered. Administrative authority is explicitly defined, auditable, and revocable.
- RageQuit Mechanism: Enforces accountability. If governance becomes hostile, token holders can burn their tokens and exit with a proportional share of assets, preventing permanent lock-in.
- Emergency Pause: Governed by Guardians, this system is time-bounded. It automatically expires after a fixed duration, preventing permanent freezes or hidden backdoors.
- Anti-Spam: Proposal submission is protected through reputation checks and cooldown windows to prevent governance flooding.
- Custody Rules: Funds cannot be moved by admins directly. Transfers are possible only through Timelock execution or the RageQuit mechanism.
- Multi-Asset Vault: Capable of holding ETH, ERC20, ERC721, and ERC1155 tokens.
- DeFi Integration: Idle assets are programmatically deployed to Aave V3 via
TreasuryYieldStrategy, turning the treasury into an active participant.
- Off-Chain Bridge: Snapshot-style voting results can be verified through EIP-712 signatures and executed on-chain without trusting centralized servers.
- Analytics: Proposal outcomes and activity metrics are recorded on-chain to support long-term health monitoring.

This codebase represents an advanced smart contract implementation adhering to production-grade standards:
- Gas-Aware Design: Usage of custom errors and storage packing.
- Explicit Access Checks: Every sensitive function is guarded by RoleManager or Timelock.
- Testing Rigor: The system is covered by extensive unit tests, integration tests, fuzz testing, and system-level lifecycle simulations.
- Separation of Concerns: Role management, logic, and storage are decoupled to ensure upgradeability without data loss.
