Wallet Security Auditor

Overview

Security analysis tool for cryptocurrency wallets. Scans ERC20 token approvals, analyzes transaction patterns, calculates security risk scores, and provides actionable recommendations to improve wallet security.

Important: This is a read-only analysis tool. It does NOT execute transactions, manage private keys, or perform revocations.

Prerequisites

Before using this skill, ensure you have:

• Python 3.8+ with requests library installed
• Optional: ETHERSCAN_API_KEY environment variable for higher rate limits
• Network access to blockchain RPC endpoints (public RPCs included)
• Target wallet address (hex format, 0x...)

Instructions

1. List Token Approvals

Scan wallet for all active ERC20 token approvals:

cd ${CLAUDE_SKILL_DIR}/scripts
python wallet_auditor.py approvals <address> --chain <chain>

Options:

1. --chain: ethereum, bsc, polygon, arbitrum, optimism, base (default: ethereum)
2. --unlimited: Show only unlimited approvals
3. --verbose: Detailed output

2. Full Security Scan

Comprehensive security analysis including approvals, transaction history, and patterns:

python wallet_auditor.py scan <address> --verbose

Analyzes: 4. Active token approvals (unlimited, risky) 5. Transaction history patterns 6. Contract interactions (verified vs unverified) 7. Suspicious activity detection

3. Calculate Security Score

Get weighted security risk score (0-100, higher = safer):

python wallet_auditor.py score <address>
python wallet_auditor.py score <address> --json  # JSON output

Score components: 8. Approvals (40%): Unlimited, risky, stale approvals 9. Interactions (30%): Contract verification, flagged addresses 10. Patterns (20%): Transaction frequency, diversity 11. Age (10%): Wallet maturity

Risk levels: 12. 90-100: SAFE 13. 70-89: LOW 14. 50-69: MEDIUM 15. 30-49: HIGH 16. 0-29: CRITICAL

4. Analyze Transaction History

Review recent contract interactions and patterns:

python wallet_auditor.py history <address> --days 30

Detects: 17. Rapid approval patterns 18. Interaction bursts (many contracts in short time) 19. High failure rates 20. Dust attacks

5. Generate Revoke List

Get prioritized list of approvals to revoke:

python wallet_auditor.py revoke-list <address>

Flags: 21. Unlimited approvals to unknown contracts 22. Risky/flagged spenders 23. Stale approvals (>6 months)

6. Generate Full Report

Create comprehensive security audit report:

python wallet_auditor.py report <address> --output report.txt
python wallet_auditor.py report <address> --json  # JSON format

7. List Supported Chains

python wallet_auditor.py chains

Output

Approval Summary

• Total active approvals count
• Unlimited approvals flagged
• Risky approvals with severity
• Unique spenders and tokens

Risk Factors

• [CRITICAL] Unlimited approval to unknown contract
• [HIGH] Approval to flagged contract
• [MEDIUM] Many unlimited approvals (>5)
• [LOW] Interaction with unverified contract

Recommendations

• Priority 1: Revoke risky approvals immediately
• Priority 2: Review unnecessary unlimited approvals
• Priority 3: Audit all approvals periodically
