Real-Time Crypto Whale Tracker

Monitor any Ethereum wallet for large capital movements.

The Whale Watcher scans recent transactions for a target EVM wallet address and alerts you to any movement above your threshold. Uses Blockscout (no API key required) for transaction data and CoinGecko for live ETH/USD pricing.

Why use the Whale Watcher?

Track smart money: Monitor known whale wallets, VC fund addresses, or exchange cold wallets for large movements.
No API keys needed: Built on fully public, open APIs.
Threshold alerts: Only get notified when capital moves exceed your defined threshold.
Direction tracking: Know whether a large movement is an inflow or outflow.

Input

Field	Type	Default	Description
`wallet_address`	string	required	The EVM wallet address to monitor (0x...).
`threshold_usd`	integer	100000	Minimum USD value to trigger a whale alert.

Output

Each whale movement above threshold produces one alert:

{
  "wallet_address": "0xabc...def",
  "tx_hash": "0x123...456",
  "direction": "INFLOW",
  "value_eth": 450.25,
  "value_usd": 1521845.00,
  "threshold_usd": 100000,
  "from_address": "0xsender...",
  "to_address": "0xreceiver...",
  "block_number": 19823401,
  "timestamp": "2026-05-16T04:00:00.000Z",
  "status": "ok"
}

Pricing

Pay-Per-Event — charged only per whale alert detected above your threshold.

$0.10 per whale alert.

If no movements exceed your threshold, no charge is incurred.
