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
