# 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:

```bash
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:

```bash
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):

```bash
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:

```bash
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:

```bash
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:

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

### 7. List Supported Chains

```bash
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

## Error Handling

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

| Error | Cause | Solution |
|-------|-------|----------|
| Address validation failed | Invalid format | Use 0x + 40 hex characters |
| RPC timeout | Node unresponsive | Retry or use different RPC |
| Rate limited | Too many requests | Add ETHERSCAN_API_KEY |
| No approvals found | Wallet clean | Normal - no action needed |

## Examples

See `${CLAUDE_SKILL_DIR}/references/examples.md` for detailed examples.

### Quick Security Check
```bash
# Check wallet approvals
python wallet_auditor.py approvals 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

# Full security scan
python wallet_auditor.py scan 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 --verbose

# Get security score
python wallet_auditor.py score 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

# Check other chains
python wallet_auditor.py approvals 0x... --chain polygon
python wallet_auditor.py approvals 0x... --chain arbitrum
```

### Generate Audit Report
```bash
# Text report
python wallet_auditor.py report 0x... --output security_audit.txt

# JSON for integration
python wallet_auditor.py report 0x... --json --output audit.json
```
