Insider Wallet Movement Alert

WHAT IT DOES

Insider Wallet Movement Alert watches the current Etherscan address page for the displayed wallet address, reads the wallet's recent transaction history via the Etherscan API, monitors for large movements of tokens or ETH, calculates movement significance relative to wallet size, and displays alerts with transaction details, direction, and risk assessment when significant insider-like movements are detected. The tool extracts the wallet address from the page URL, fetches recent transaction data from the Etherscan API, stores historical transaction snapshots locally to detect new movements, calculates the USD value of each transaction using approximate token prices, and analyzes movement patterns for significance relative to wallet size and transaction frequency. It then classifies movements by risk level — Medium, High, or Critical — based on the size relative to the configured threshold, and displays alerts with transaction hashes, amounts, direction (IN/OUT), and risk assessment.

WHERE IT RUNS

The tool runs as a panel inside your browser on Etherscan address pages at https://etherscan.io/address/* or token pages at https://etherscan.io/token/*. It works on any wallet address page on Etherscan where transaction history is available through the Etherscan API. The tool connects to the Etherscan public API via GM_xmlhttpRequest to fetch transaction data. No data is sent to any external server beyond the API request; all data is read-only and processed locally. A real EVM wallet is not required for this tool to function, as it monitors wallet addresses visible on Etherscan, but it will check for one and provide additional on-chain balance verification if available.

HOW TO USE

Install the BotGentz extension, navigate to any Etherscan address page, and open the Insider Wallet Movement Alert panel. Set your minimum movement threshold in USD (default $100,000) — the tool will alert you when any transaction exceeding this value is detected. Set the number of recent transactions to check (default 10) — this controls how many past transactions are compared against each new fetch. Select your monitoring interval from the dropdown — 30, 60, 120, or 300 seconds. Choose your alert preference — Panel only, Browser notification, or Both. Click "Start Monitoring" — the tool begins fetching transaction data from the Etherscan API at your chosen interval, stores historical transaction hashes locally, and compares each new fetch against the stored history. When a new transaction exceeds the threshold, the tool triggers an alert with the transaction hash, amount, direction, and risk level. The alert log maintains a history of recent alerts for review. Click "Refresh" to manually check for new transactions, or "Clear History" to reset the alert log.

MECHANISM — API-BASED TRANSACTION MONITORING WITH RISK CLASSIFICATION

This tool uses an API-based transaction monitoring engine that fetches wallet transaction history from Etherscan's public API. The system first extracts the wallet address from the page URL path, then constructs the Etherscan API endpoint URL (https://api.etherscan.io/api?module=account&action=txlist&address={address}&sort=desc&offset={limit}). It uses GM_xmlhttpRequest with GET method to fetch the transaction list, which returns a JSON array of transaction objects containing hash, from, to, value, and other metadata. The tool stores transaction hashes from each fetch in a local history object keyed by wallet address using GM_setValue to persist data across page reloads. On each monitoring cycle, the tool compares the current transaction list against the stored history, filtering out transactions already seen and identifying new transactions. It calculates the USD value of each new transaction using a simplified price estimation function, and classifies the risk level based on the transaction value relative to the configured threshold: Critical (≥ 5× threshold), High (≥ 3× threshold), or Medium (≥ threshold). The alert triggering system activates based on the classification and user preferences, sending browser notifications via GM_notification and updating the panel display with color-coded risk indicators.

THE PANEL

The BotGentz panel is fully draggable, allowing you to position it anywhere on your screen without obstructing the Etherscan interface. It includes per-site position memory, so the panel returns to your preferred location each time you visit an address page. Snap-to-edge functionality lets you dock the panel to any side of the browser window. The panel collapses to a compact icon when not in use and expands with a single click. You can resize it to your preferred dimensions, and pressing the Escape key instantly closes the panel. All interactions are smooth and intuitive, designed to work alongside your blockchain investigation workflow.

PLEASE NOTE

This tool requires the free BotGentz extension to function. A real EVM wallet extension is optional — the tool will work without one, but may provide additional on-chain balance verification if available. EVM chains only. This is a monitoring and alert tool only — it does not execute transaction-based actions automatically. The tool cannot guarantee that the API data includes all mempool transactions or pending movements. It cannot account for token price changes between data fetches. It cannot read transaction history from wallets not visible on Etherscan. It cannot detect movement across multiple wallets or complex patterns. It cannot predict future wallet movements or insider activity. It cannot read private wallet information or transaction intentions. All API data is fetched through public endpoints; no data is stored or transmitted beyond your browser. Websites change their layouts and content structures regularly; while we continuously update the extraction logic, some pages may require script updates. Always verify all transaction details independently before making any decisions based on the alerts.
