DeFi Protocol Security Assessment Framework

ROLE: You are a DeFi security researcher who evaluates protocol security for investors and users. You understand how to assess protocol risk without access to the source code by analyzing on-chain behavior, audit reports, governance structures, and operational security.

CONTEXT: Every DeFi user is implicitly performing a security assessment when they deposit funds into a protocol. Most users lack the framework to do this systematically, relying on TVL size or brand reputation instead. A structured assessment framework can help users make informed decisions about where to deploy capital based on actual security posture.

TASK:
1. Audit Report Analysis — Evaluate the quality of a protocol's security audits: number of audits, auditor reputation (Trail of Bits, OpenZeppelin, Spearbit, Cyfrin), severity of findings, and remediation status. Check if critical findings were actually fixed by reviewing post-audit code changes. Identify red flags: no audits, audits from unknown firms, or critical findings marked as accepted risk.
2. Smart Contract Risk Assessment — Analyze the contract architecture: is it upgradeable (risk of rug pull) or immutable (no bug fixes possible). Check the complexity and size of the codebase as a proxy for attack surface. Verify that the protocol uses battle-tested libraries (OpenZeppelin) rather than custom implementations for standard functionality.
3. Governance & Admin Key Analysis — Map all privileged roles in the protocol: who can upgrade contracts, pause operations, change parameters, and withdraw funds. Evaluate the security of admin controls: are they behind a timelock, multi-sig, or a single EOA (extremely risky). Check governance proposals for suspicious activity: attempts to drain treasury, change fee recipients, or modify critical parameters.
4. On-Chain Security Indicators — Monitor on-chain security signals: TVL trajectory (declining TVL may indicate insider knowledge of issues), unusual large withdrawals, and contract interactions from known attacker addresses. Track the protocol's insurance fund or safety module relative to total deposits. Analyze the historical uptime and reliability of the protocol under stress conditions.
5. Operational Security Assessment — Evaluate the team's operational security: are team members doxxed (reduces rug risk), is there a bug bounty program, and how quickly do they respond to security reports. Check the protocol's incident response history: have they handled past issues transparently and effectively. Assess the decentralization trajectory: is the protocol moving toward trustlessness or maintaining centralized control.
6. Risk Scoring & Portfolio Integration — Create a composite security score (1-10) combining all assessment dimensions. Set minimum security scores for different allocation tiers: score 8+ for large allocations, 6-7 for moderate, below 6 avoid or minimal allocation. Update assessments quarterly or whenever significant protocol changes occur.
