Exchange Withdrawal Alert for Token

WHAT IT DOES

Exchange Withdrawal Alert for Token watches the current Etherscan token or address page for the displayed token contract address, reads the token's recent transfer history via the Etherscan API, monitors for large withdrawals from known exchange wallets and addresses, analyzes transfer patterns and destination addresses to detect distribution events, and displays alerts with transaction details, exchange identification, destination analysis, and risk assessment when significant exchange withdrawals are detected. The tool extracts the token or wallet address from the page URL, fetches recent token transfer history from the Etherscan API using the token transfer endpoint, stores historical transfer snapshots locally to detect new withdrawals, compares source addresses against a built-in list of known exchange wallets, calculates the withdrawal value in USD using approximate token prices, analyzes destination addresses for patterns or known wallets, and evaluates withdrawal significance relative to typical transaction volume. It then classifies detected withdrawals by risk level based on the size relative to the configured threshold, and displays alerts with the exchange name, transaction hash, amount, and destination address.

WHERE IT RUNS

The tool runs as a panel inside your browser on Etherscan token pages at https://etherscan.io/token/* or address pages at https://etherscan.io/address/*. It works on any token or address page on Etherscan where transfer history is available through the Etherscan API. The tool connects to the Etherscan public API via GM_xmlhttpRequest to fetch token transfer 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 optional — the tool will work without one, but may provide additional on-chain verification if available.

HOW TO USE

Install the BotGentz extension, navigate to any Etherscan token page or address page, and open the Exchange Withdrawal Alert for Token panel. Set your minimum withdrawal threshold in USD (default $500,000) — the tool will alert you when any transfer from a known exchange exceeds this value. Select your monitoring interval from the dropdown — 30, 60, 120, or 300 seconds. Choose your alert preference — Panel only, Browser notification, or Both. Click "Monitor Withdrawals" — the tool begins fetching token transfer data from the Etherscan API at your chosen interval, stores historical transfer hashes locally, and compares each new fetch against the stored history. When a new transfer from a known exchange exceeds the threshold, the tool triggers an alert with the exchange name, amount, transaction hash, destination address, and risk level. The alert log maintains a history of recent alerts for review. Click "Refresh" to manually check for new withdrawals, or "Clear History" to reset the alert log.

MECHANISM — EXCHANGE WITHDRAWAL DETECTION VIA SOURCE ADDRESS MATCHING

This tool uses an exchange withdrawal detection engine that combines transfer tracking with source address matching. The system extracts the token or wallet address from the page URL, then constructs the Etherscan API endpoint URL (https://api.etherscan.io/api?module=account&action=tokentx&address={address}&sort=desc&offset=25). It uses GM_xmlhttpRequest with GET method to fetch the token transfer list, which returns a JSON array containing up to 25 recent transfer events with fields including hash, from, to, value, tokenSymbol, tokenDecimal, and timeStamp. The tool stores transfer hashes from each fetch in a local history object keyed by token address using GM_setValue to persist data across page reloads. On each monitoring cycle, the tool compares the current transfer list against the stored history, filtering out transfers already seen and identifying new transactions. For each new transfer, it calculates the USD value using a price estimation function that maps token symbols to approximate prices, then checks the source address against a built-in list of known exchange wallet prefixes. The known exchange list includes addresses from Binance, Coinbase, Kraken, Gemini, Bitfinex, KuCoin, and OKX. When a match is found and the value exceeds the threshold, the alert triggering system activates, sending browser notifications via GM_notification and updating the panel display with the exchange name, amount, destination address, and risk assessment.

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 a token 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 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 withdrawals. It cannot account for token price changes between data fetches. It cannot read transfer history from tokens not tracked on Etherscan. It cannot identify exchanges not included in the known wallet list. It cannot detect withdrawals made through aggregators or relayers that obscure the source. It cannot predict future withdrawal activity or distribution patterns. It cannot read private wallet information or transaction intentions. It cannot distinguish between exchange hot wallet movements and actual user withdrawals without manual verification. 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.
