The skill uses public RPC endpoints configured in `scripts/lib/rpc.js`. ### Custom RPC Endpoints (Advanced) To use custom RPC endpoints, modify the `CHAINS` object in `scripts/lib/rpc.js`: ```javascript const CHAINS = { apechain: { id: 33139, rpc: "your-custom-rpc-url", name: "ApeChain", symbol: "APE", explorer: "https://apescan.io" }, // ... other chains }; ``` ## Error Handling & Reliability ### Automatic Retry Logic - 3 retry attempts with exponential backoff (500ms, 1s, 2s) - 10-second timeout per request - Graceful failure with clean error messages ### Input Validation - Address format validation (0x + 40 hex characters) - Chain name validation against supported list - Clean error messages without stack traces ### Common Error Messages ```json {"error": "Invalid address format. Address must be 0x followed by 40 hexadecimal characters"} {"error": "Unsupported chain \"invalidchain\". Supported chains: apechain, ethereum, base, arbitrum, polygon, optimism, avalanche, bsc"} {"error": "RPC request timed out after 10000ms"} ``` ## Performance & Limitations ### Response Times - **Fast (< 1s)**: ApeChain, Arbitrum - **Good (1-2s)**: Ethereum, Base - **Variable (1-5s)**: Polygon, Optimism, BSC, Avalanche ### Data Coverage - **Recent Activity**: 500K-2M blocks depending on chain performance - **Historical Limitations**: Very old transactions may not appear - **NFT Detection**: ERC-721 and ERC-1155 support via Transfer events - **Bot Analysis**: Requires minimum 3 NFT purchases for scoring ### Resource Usage - **Memory**: Minimal - processes data in streams - **Network**: Burst usage during queries, then idle - **CPU**: Low - mostly I/O bound operations ## Troubleshooting ### Network Issues ```bash # If RPC timeouts occur, try different chain: node scripts/wallet-lookup.js <address> --chain ethereum # For intermittent chains, retry usually succeeds: node scripts/wallet-lookup.js <address> --chain polygon ``` ### Empty Results - Verify address is active on the selected chain - Try different chain if cross-chain activity expected - Increase block scan range for older activity ### Performance Optimization - Use `--limit` parameter to reduce transaction history size - Choose reliable chains (ApeChain, Ethereum, Base, Arbitrum) for consistent performance - Monitor response times and adjust expectations per chain ## Advanced Usage ### Batch Analysis ```bash # Analyze multiple addresses for addr in 0xaddr1 0xaddr2 0xaddr3; do echo "=== Analysis for $addr ===" node scripts/wallet-lookup.js $addr --pretty node scripts/bot-detect.js $addr --pretty echo done ``` ### Cross-Chain Investigation ```bash # Check same address across multiple chains for chain in apechain ethereum base arbitrum; do echo "=== $chain ===" node scripts/wallet-lookup.js 0x8dd6390be6dc732c92b161b9793a3948b56c0126 --chain $chain --pretty done ``` ### Collection Analysis ```bash # Focus on specific NFT collection node scripts/nft-holdings.js <address> --collection 0x<contract> --pretty ``` ## References - **Chain Details**: [references/CHAINS.md](references/CHAINS.md) - Comprehensive chain status and performance data - **Bot Scoring**: [references/bot-scoring.md](references/bot-scoring.md) - Detailed bot detection methodology ## Version History - **v2.0**: Added retry logic, input validation, pretty formatting, comprehensive chain documentation - **v1.0**: Initial release with basic multi-chain support and bot detection --- *Need help?

**Results**: 
- ✅ USD pricing working: "32.12 ETH (~$66,152.36)"  
- ✅ Contract detection working
- ✅ Cross-chain balance retrieval successful
- ✅ Explorer links correct for Ethereum

### Chain Performance (Updated)
- **ApeChain**: ~1.5s (slight increase due to new features)
- **Ethereum**: ~2.8s (USD pricing adds ~0.5s)
- **Base/Arbitrum**: Expected similar performance profile

---

## Regression Analysis vs v2.0 ✅

- ✅ Collection name resolution is additive (graceful fallback)
- ✅ USD pricing is additive (null when unavailable)

---

## Performance Impact Analysis

### Response Time Changes
- **Baseline (v2.0)**: ~1.2s average
- **Enhanced (v3.0)**: ~1.7s average  
- **Increase**: +0.5s due to:
  - CoinGecko API call: +0.3s  
  - Collection name resolution: +0.2s
  - Both use caching to minimize repeated calls

### Network Efficiency
- ✅ CoinGecko cached for 5 minutes (one call serves multiple queries)
- ✅ Collection names cached in-memory per script run  
- ✅ Alchemy API used only when available (graceful degradation)
- ✅ No redundant RPC calls added

---

## Known Issues & Limitations

### 1. ENS Resolution (Blocked)
- **Issue**: keccak256 hashing not available in Node.js crypto module
- **Impact**: Cannot resolve .eth names currently
- **Workaround**: Clear error message directs users to use wallet addresses
- **Fix Required**: Add external keccak dependency or implement alternative

### 2. Alchemy API Dependency (Minor)
- **Issue**: Collection names work better with ALCHEMY_API_KEY
- **Impact**: Without key, falls back to RPC + short addresses  
- **Mitigation**: Fully functional without API key (graceful degradation)

### 3. CoinGecko Rate Limits (Minor)
- **Issue**: Free tier has 10-30 req/min limit
- **Impact**: Burst testing may hit limits
- **Mitigation**: 5-minute caching + graceful degradation

---

## Environment Variables Status

### Optional (Enhance Features)
- ✅ `ALCHEMY_API_KEY` - Improves collection name resolution

---

## Issues Found & Fixes Applied

### 🔴 CRITICAL: Zero Address Hanging (FIXED)
**Issue:** `wallet-lookup.js` hung indefinitely when queried with `0x0000000000000000000000000000000000000000`

**Root Cause:** The zero address is involved in millions of mint operations (Transfer events from 0x0), causing eth_getLogs to return massive datasets and timeout.

**Fix Applied:** Added special handling in wallet-lookup.js:
```javascript
// Handle special addresses that could cause performance issues  
const isZeroAddress = address.toLowerCase() === "0x0000000000000000000000000000000000000000";
const isDeadAddress = address.toLowerCase() === "0xdeaddeaddeaddeaddeaddeaddeaddeaddeaddead";

// Skip log queries for problematic addresses to avoid timeouts
if (!isZeroAddress && !isDeadAddress) {
  // ... perform log queries
}
```

**Result:** Zero address now returns in 0.54s with basic balance info.

### 🟡 MODERATE: RPC Endpoint Reliability
**Issue:** Several RPC endpoints (Polygon, Optimism, BSC) timeout or fail intermittently.

**Impact:** Multi-chain functionality limited to 4/8 chains during testing.

**Recommendation:** Consider implementing:
- Retry logic with exponential backoff
- Fallback RPC endpoints for each chain  
- Health check endpoints before queries
- User-configurable RPC URLs

---

## Code Quality Assessment

### ✅ Strengths
- **Consistent JSON output** across all scripts
- **Good error handling** for invalid addresses
- **Modular design** with shared lib/rpc.js
- **Clear command-line interface** with helpful usage messages
- **Multi-chain abstraction** works well
- **Comprehensive data** returned (balances, tx counts, NFT holdings, bot scores)

### 🔧 Areas for Improvement
1. **RPC resilience** - Add retry logic and fallback endpoints
2. **Rate limiting** - Add delays between rapid requests  
3. **Caching** - Cache chain data and contract info
4. **Progress indicators** - For long-running queries
5. **Configuration** - Allow custom RPC endpoints via config file

---

## Recommendations

### Immediate Actions Required
1. ✅ **Deploy the zero address fix** to production (already applied)
2. 🔧 **Update documentation** to mention RPC endpoint limitations
3. 🔧 **Add retry logic** for failed RPC calls

### Future Enhancements
1. **RPC Health Monitoring** - Periodic endpoint health checks
2. **Configuration System** - User-configurable RPC endpoints  
3. **Data Caching** - Cache static data (contract info, etc.)
4. **Batch Queries** - Combine multiple queries where possible
5. **Verbose Mode** - Add --verbose flag for debugging

---

## Final Verdict

## Performance Characteristics

### Response Time Expectations
- **Fast (< 1s):** ApeChain, Arbitrum
- **Good (1-2s):** Ethereum, Base
- **Variable (1-5s):** Polygon, Optimism, BSC, Avalanche

### Resource Requirements
All chains use similar resource patterns:
- **eth_getBalance:** Very fast (~100ms)
- **eth_getTransactionCount:** Fast (~200ms)
- **eth_getCode:** Fast (~200ms)
- **eth_getLogs:** Slow (1-5s, depends on block range and activity)

### Block Range Recommendations
- **ApeChain:** Up to 2M blocks (excellent performance)
- **Ethereum:** Up to 500K blocks (balance speed vs completeness)
- **L2 Networks:** Up to 1M blocks (faster block times)
- **Other Networks:** Start with 100K blocks, increase as needed

---

## Troubleshooting

### Common Issues

#### Timeout Errors
**Symptoms:** `RPC request timed out after 10000ms`  
**Solutions:**
1. Reduce block scan range (--limit parameter)
2. Retry with exponential backoff (built-in)
3. Switch to alternative RPC endpoint
4. Use different chain if cross-chain data acceptable

#### Rate Limiting
**Symptoms:** `HTTP 429: Too Many Requests`  
**Solutions:**
1. Add delays between requests
2. Use different RPC endpoint
3. Implement request queuing

#### Empty Results
**Symptoms:** No transactions/NFTs found for active addresses  
**Possible Causes:**
1. Chain mismatch (address active on different chain)
2. Block range too small
3. RPC endpoint synchronization lag

### Best Practices

1. **Always use retry logic** for intermittent chains
2. **Start with reliable chains** (ApeChain, Ethereum, Base, Arbitrum)
3. **Monitor response times** and adjust timeouts accordingly
4. **Have fallback RPC endpoints** for critical operations
5. **Cache results** where appropriate to reduce API calls

---

## Future Improvements

### Planned Enhancements
1. **Health monitoring** - Automatic endpoint health checks
2. **Auto-failover** - Switch to backup RPC on failure
3. **Dynamic timeouts** - Adjust based on historical performance
4. **Custom RPC support** - Allow user-configured endpoints
5. **Batch requests** - Combine multiple queries for efficiency

### RPC Endpoint Rotation
Consider implementing RPC endpoint pools for better reliability:

```javascript
const RPC_POOLS = {
  polygon: [
    "https://polygon.llamarpc.com",
    "https://polygon-rpc.com", 
    "https://rpc-mainnet.maticvigil.com"
  ],
  // ... other chains
};
```

path: references/bot-scoring.md
content: # Bot Detection Scoring — Reference

## Score Weights (100 total)

| Signal | Points | Description |
|--------|--------|-------------|
| wAPE Ratio | 30 | % of NFT buys paid with wAPE instead of native APE. Bots use wAPE for programmatic approvals. |
| Fast Flip | 25 | Buy→sell within 24 hours. Bots flip quickly for profit. |
| Fast List | 20 | Buy→list within 30 minutes. Bots auto-list immediately after purchase. |
| Aggressive Pricing | 15 | Listings significantly below floor price (>2% under). Bots undercut to sell fast. |
| Cross-Collection | 10 | Activity spread across many collections (>10 = max score). Bots spray across collections. |

## Verdicts

| Score Range | Verdict |
|-------------|---------|
| 0-19 | `human` — Normal wallet activity |
| 20-39 | `probably_human` — Some automated patterns but likely human |
| 40-59 | `suspicious` — Mixed signals, needs manual review |
| 60-74 | `likely_bot` — Strong bot patterns detected |
| 75-100 | `definite_bot` — Overwhelming bot indicators |

## Minimum Data

Requires at least 3 NFT buys to generate a score. Below that threshold, returns `insufficient_data`.

## wAPE Detection

wAPE contract on ApeChain: `0x48b62137edfa95a428d35c09e44256a739f6b557`

Bots prefer wAPE because:
- ERC-20 approve() allows programmatic spending
- No need for native APE gas estimation per-tx
- Batch operations are easier with token approvals
