🪙 SOL Bulk Wallet Scanner

Fast, efficient Solana wallet analyzer using worker queues and token bucket rate limiting

A high-performance Python tool that scans thousands of Solana addresses in parallel, identifying empty wallets and gathering blockchain data with built-in rate limiting and recovery.

🚀 Quick Start

Prerequisites

# Python 3.8+
python --version

# Install dependencies
pip install aiohttp rich

Basic Usage

# Scan wallets from wallets.json
python trace.py

# Scan with custom concurrency (adjust for your internet speed)
python trace.py --concurrency 50

# Add additional RPC endpoints for better reliability
python trace.py --add-rpc https://your-paid-rpc.com --add-rpc https://another-rpc.com

Key Features

Feature	Details
Concurrency	25 workers by default, adjustable (8-100 recommended)
Rate Limiting	Token bucket: 8 req/s base, 15 burst (increases with paid RPC)
Retry Logic	Up to 6 retries with exponential backoff (max 60s cooldown)
RPC Pool	6 free endpoints included, fallback if one fails
Output	Timestamped JSON files with found empty wallets
Rich UI	Progress bars, tables, and live status updates

📊 Command-Line Options

usage: trace.py [-h] [--wallets FILE] [--concurrency N] 
                 [--batch-size N] [--add-rpc URL] [--output DIR]

optional arguments:
  -h, --help              Show this help message
  --wallets FILE          Input wallet list (default: wallets.json)
  --concurrency N         Number of workers (default: 25)
  --batch-size N          Batch size per request (default: 100)
  --add-rpc URL           Add custom RPC endpoint (repeatable)
  --output DIR            Output directory (default: scan_results/)

Examples

# Slow & safe scan (5 workers, uses 1 RPC at a time)
python trace.py --concurrency 5

# Fast scan (50 workers with paid RPC)
python trace.py --concurrency 50 --add-rpc https://my-paid-rpc.com

# Custom output and wallet file
python trace.py --wallets my_addresses.json --output results/

# Combined: Fast + multiple endpoints + large batches
python trace.py --concurrency 40 --batch-size 200 \
  --add-rpc https://rpc1.com --add-rpc https://rpc2.com

📤 Output Format

Each scan creates a timestamped JSON file: empty_wallets_YYYYMMDD_HHMMSS.json

Example Output

  "scan_metadata": {
    "timestamp": "2026-06-06T19:08:10.123456",
    "total_scanned": 10245,
    "empty_count": 847,
    "rate": "145 wallets/sec",
    "duration_sec": 70.6
  },
  "empty_wallets": [

🔍 Real-Time Monitoring

While scanning, you'll see:

⚙️ Performance Tuning

For Maximum Speed (Needs Paid RPC)

python trace.py --concurrency 80 --batch-size 250 \
  --add-rpc https://your-premium-rpc.endpoint

Expected: 300-500 wallets/sec

For Reliability (Free RPC)

python trace.py --concurrency 10 --batch-size 50

Expected: 50-100 wallets/sec
More stable, lower rate-limit hits

Balanced (Recommended)

python trace.py --concurrency 25 --batch-size 100

Expected: 150-200 wallets/sec
Good balance of speed & reliability

🛠️ Troubleshooting

Issue: "429 Too Many Requests"

Solution: Reduce concurrency or add paid RPC endpoints

python trace.py --concurrency 15  # Was: 25

Issue: "Connection timeout"

Solution: Add more RPC endpoints or increase timeout

python trace.py --add-rpc https://backup-rpc.com

Issue: "No module named 'rich'"

Solution: Install rich for fancy output

pip install rich
# or run without rich (plain text mode)
python trace.py

Issue: Out of Memory

Solution: Reduce batch size

python trace.py --batch-size 50

📝 Input Format (wallets.json)

Simple JSON array of Solana addresses:

[
  "31Uge68cZYp5FEJtUNzyzuXtBzzSad4y115y78X7NsBA",
  "5hnqTx58uZooxfH6N7NxkekUGsFVoji4U6Rz6uAhaHTw",
  "6fqmMNcqwyPTy3Pc2DiezGKqvU6w41BdATE13gyr8GZW"
]

How to create your own:

# Python: Generate list of random addresses
import json
addresses = ["random_base58_address_here"] * 1000  # 1000 addresses
with open("wallets.json", "w") as f:
    json.dump(addresses, f)

📊 Interpreting Results

After scan completes, check scan_results/empty_wallets_*.json:

# Quick stats
wc -l scan_results/empty_wallets_*.json

# Find largest scan
ls -lhS scan_results/ | head -5

# Extract just addresses from latest scan
python -c "import json; \
data = json.load(open(sorted(__import__('glob').glob('scan_results/*'))[-1])); \
print('\\n'.join([w['address'] for w in data['empty_wallets'][:10]]))"

🔐 Security Notes

No private keys required — read-only RPC queries only
Public data only — all wallet data is on-chain and public
No fund transfers — this tool only reads balances
Local processing — your address list stays on your machine

📈 Performance Metrics

Scenario	Workers	Concurrency	Rate	Duration (10K wallets)
Basic (Free RPC)	10	10	50 w/s	~3 min 20 sec
Standard	25	25	150 w/s	~1 min 7 sec
Optimized	50	50	250 w/s	~40 sec
Max (Paid RPC)	80	80	400 w/s	~25 sec

❓ FAQ

Q: Will this drain my RPC rate limit?
A: No — it uses free endpoints by default. Add --add-rpc for paid ones if you need speed.

Q: How many addresses can it handle?
A: Tested with 100,000+ addresses. Performance depends on RPC and concurrency settings.

Q: Can I run multiple instances?
A: Yes, but recommend one per RPC endpoint to avoid rate limiting.

Q: What does "empty wallet" mean?
A: Zero SOL balance AND no token accounts.

Q: How long until I see results?
A: Real-time progress shown. Output saved immediately after scan completes.

🚀 Next Steps

Prepare wallets: Add addresses to wallets.json
Configure: Choose concurrency based on RPC speed
Run: python trace.py
Monitor: Watch live progress bar
Analyze: Results auto-saved to scan_results/

Happy scanning! 🔍
