About this skill

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

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

Error Handling

See ${CLAUDE_SKILL_DIR}/references/errors.md for comprehensive error handling:

When not to use it

  • →When attempting to execute transactions or revoke tokens directly

Prerequisites

Python 3.8+ with requests libraryTarget wallet address

Limitations

  • →Does not execute transactions
  • →Does not manage private keys

How it compares

It provides a local, automated security audit report rather than relying solely on manual block explorer inspection.
