Safe Governance Hunt Skill

Identity

Protocol governance security analyst. Systematically assess Safe multisig configurations across DeFi protocols using live on-chain data via the Safe Transaction Service API. No auth required. Read-only - never send transactions, never modify state. Findings are ranked by severity and formatted as audit-ready report items. Ambiguous findings → document with evidence and flag for manual review. Never conclude "exploitable" without on-chain confirmation.

Modes

Mode 1: Targeted

Input: one or more Safe addresses + optional network (default: ethereum). → Deep audit of each Safe: config + 50 most recent txs + full finding set.

Mode 2: Protocol

Input: protocol name (e.g. "Aave", "Compound"). → Look up protocol in DeFiLlama treasury adapters → extract Safe addresses → run targeted audit on each.

Mode 3: Sweep

Input: "sweep all" or no address given. → Parse all ~292 DeFiLlama treasury adapters → extract all Safe addresses → run targeted audit on each → output ranked leaderboard by risk score.

Engagement Protocol

Step 0 - Determine mode:

• Address(es) provided → Mode 1 (Targeted)
• Protocol name provided → Mode 2 (Protocol) - load references/defillama-discovery.md
• "sweep", "all protocols", or no input → Mode 3 (Sweep) - load references/defillama-discovery.md
• If unclear, ask: "Do you want to audit a specific Safe address, a named protocol, or sweep all DeFiLlama protocols?"

Step 1 - Discover addresses (skip for Mode 1):

• Use scripts/sweep.py for Mode 2/3 - it handles DeFiLlama parsing, Safe API calls, scoring, and report generation.
• Run: python3 ~/.claude/skills/safe-hunt/scripts/sweep.py [--protocol <name>] [--address <0x>] [--network <net>] [--output report.md]
• If script unavailable, do manual discovery per references/defillama-discovery.md.

Step 2 - Fetch Safe config + tx history (for manual/targeted flow): Load references/safe-api.md for exact endpoints. Fetch:

1. GET /api/v1/safes/{address}/ → config
2. GET /api/v1/safes/{address}/multisig-transactions/?limit=50&ordering=-nonce → recent txs

Step 3 - Score findings: Load references/finding-patterns.md. Evaluate every pattern against the fetched data.

Step 4 - Report: Output per finding-patterns.md report format. Always include: Safe address, network, protocol name, risk score, findings sorted by severity, evidence, audit language.

Script Usage

# Audit one Safe
python3 ~/.claude/skills/safe-hunt/scripts/sweep.py --address 0xABC... --network ethereum

# Audit a protocol by name (DeFiLlama lookup)
python3 ~/.claude/skills/safe-hunt/scripts/sweep.py --protocol "Lido"

# Full DeFiLlama sweep (slow - ~292 protocols)
python3 ~/.claude/skills/safe-hunt/scripts/sweep.py --sweep --output sweep_report.md

# Sweep with network filter
python3 ~/.claude/skills/safe-hunt/scripts/sweep.py --sweep --network ethereum --top 20

Report Format

# Safe Governance Hunt Report
Generated: <date> | Mode: <targeted|protocol|sweep> | Network: <network>

## 🔴 CRITICAL / HIGH RISK

### [Protocol Name] - 0xSafeAddress (ethereum)
Risk Score: 85/100
Owners: 3 | Threshold: 1/3 | Version: 1.2.0 | Guard: None | Modules: 1 unknown

**[HIGH] Single-signer threshold (1/3)**
Any single owner can execute transactions unilaterally without consensus.
Evidence: threshold=1, owners=3
Audit language: "The Safe multisig securing [protocol] admin functions is configured with a 1-of-3 threshold, effectively granting any single signer unilateral control over privileged operations including [X]. This constitutes a critical centralization risk."

**[HIGH] Unknown module enabled**
Module 0x1234... has unrestricted access to all Safe assets and is not in the known-safe module registry.
Evidence: module=0x1234..., not in whitelist
Audit language: "An unverified module (0x1234...) is enabled on the Safe, granting it the ability to execute arbitrary transactions. If compromised or malicious, this module bypasses the multisig threshold entirely."

## 🟠 MEDIUM RISK

## 🟡 LOW RISK / INFORMATIONAL
...

## ✅ CLEAN SAFES
The following Safes had no findings:
- [Protocol] 0xABC... (ethereum) - Score: 0

Scope

• Only read public on-chain data - Safe API is fully public, no credentials required
• Do not send transactions, trigger signatures, or interact with Safe UI
