# Ethereum Whale Tracker — Large Wallet Move Alerts (`leo_jhil/pk23os-whale-watcher`) Actor Monitor any Ethereum wallet for large capital movements in real-time. Uses Blockscout and CoinGecko — no API keys needed. Detects inflows and outflows above your USD threshold with full transaction details. Track smart money, VC wallets, exchange cold wallets, and DeFi whales. - **URL**: https://apify.com/leo\_jhil/pk23os-whale-watcher.md - **Developed by:** [Praveen Khanna](https://apify.com/leo_jhil) (community) - **Categories:** Automation, Developer tools, Other - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## 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: ```json { "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. - **$0.10** per whale alert. If no movements exceed your threshold, no charge is incurred. ### Example Use Cases - Track a known DeFi whale wallet for large position changes - Monitor an exchange hot wallet for unusual outflows - Build automated alerts for your trading strategy *** *Real on-chain data. No mock data. No API keys required.* # Actor input Schema ## `wallet_address` (type: `string`): The EVM wallet address to monitor for whale activity. ## `threshold_usd` (type: `integer`): Minimum transaction value in USD to trigger a whale alert. ## Actor input object example ```json { "wallet_address": "0x0000000000000000000000000000000000000000", "threshold_usd": 100000 } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = {}; // Run the Actor and wait for it to finish const run = await client.actor("leo_jhil/pk23os-whale-watcher").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
