🐋 Crypto Whale Tracker

Track massive crypto transfers in real-time. Know what the whales are doing before the market reacts.

Quick Start

# Track whale transfers above 100 BTC
bash scripts/whale_tracker.sh --coin BTC --threshold 100

# Monitor ETH whales with custom timeframe
bash scripts/whale_tracker.sh --coin ETH --threshold 500 --hours 24

# Generate HTML report
bash scripts/whale_tracker.sh --coin BTC --threshold 50 --format html --output whale_report.html

# Track specific wallet
bash scripts/whale_tracker.sh --wallet 0xABC123... --chain ethereum

How It Works — Step by Step

Step 1: Data Collection

The tool queries public APIs (Whale Alert free tier, Etherscan, Blockchair) to fetch recent large transactions. No API key is required for basic usage, but adding one increases rate limits.

Step 2: Filtering

Transactions are filtered by your specified threshold. Only transfers above the minimum amount are included. Known exchange wallets are labeled automatically.

Step 3: Classification

Each transfer is classified into categories:

• Exchange → Exchange: Likely OTC or internal transfer
• Exchange → Unknown: Possible withdrawal (bullish signal)
• Unknown → Exchange: Possible deposit for selling (bearish signal)
• Unknown → Unknown: Whale-to-whale transfer

Step 4: Report Generation

Results are formatted into a clean report with:

• Transaction hash and timestamp
• Source and destination (with exchange labels)
• Amount in crypto and estimated USD value
• Movement classification and market signal

Supported Chains

Chain	Coin	API Source
Bitcoin	BTC	Blockchair, Whale Alert
Ethereum	ETH, ERC-20	Etherscan, Whale Alert
BSC	BNB, BEP-20	BscScan
Tron	TRX, TRC-20	Tronscan
Solana	SOL	Solscan

Exchange Wallet Labels

The tool ships with a built-in database of known exchange wallets covering:

• Binance, Coinbase, Kraken, OKX, Bybit
• Bitfinex, Huobi, KuCoin, Gate.io
• Gemini, Bitstamp, FTX (historical)

Use Cases

1. Market Sentiment: Large exchange inflows often precede sell-offs
2. Accumulation Detection: Whales moving coins to cold storage = bullish
3. Stablecoin Flows: USDT/USDC whale movements signal upcoming buys
4. Alert System: Set up cron jobs to get periodic whale alerts

Cron Example

# Check every 30 minutes for BTC whales
*/30 * * * * bash /path/to/whale_tracker.sh --coin BTC --threshold 200 --hours 1 --format json >> /var/log/whale_alerts.json
