Copy-Trade Wallet Watcher

WHAT IT DOES

Copy-Trade Wallet Watcher watches the current Etherscan address page for the displayed wallet address, reads the wallet's recent transaction history via the Etherscan API, monitors for new trades including token swaps, DEX interactions, and large transfers, analyzes transaction patterns to detect trading activity, and displays alerts with transaction details, trade direction, token amounts, and risk assessment when the watched wallet executes a trade. The tool extracts the wallet address from the page URL, fetches recent transaction history from the Etherscan API using the transaction list endpoint, stores historical transaction snapshots locally to detect new trades, identifies DEX interactions by matching transaction destination addresses against a built-in list of known DEX router contracts, calculates trade value in USD using approximate token prices, and analyzes transaction patterns to determine trade direction. It then classifies detected trades by risk level based on the size relative to the configured threshold and displays alerts with the DEX name, transaction hash, token amounts, direction, and risk assessment.

WHERE IT RUNS

The tool runs as a panel inside your browser on Etherscan address pages at https://etherscan.io/address/*. 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 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 address page, and open the Copy-Trade Wallet Watcher panel. Set your minimum trade value in USD (default $10,000) — the tool will alert you when any trade 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 Trades" — 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 trade to a known DEX is detected, the tool triggers an alert with the DEX name, amount, transaction hash, direction, and token information. The alert log maintains a history of recent alerts for review. Click "Refresh" to manually check for new trades, or "Clear History" to reset the alert log.

MECHANISM — TRADE DETECTION VIA DEX ROUTER MATCHING AND DIRECTION ANALYSIS

This tool uses a trade detection engine that combines transaction monitoring with DEX router matching and direction analysis. The system extracts the wallet address from the page URL, then constructs the Etherscan API endpoint URL (https://api.etherscan.io/api?module=account&action=txlist&address={address}&sort=desc&offset=15). It uses GM_xmlhttpRequest with GET method to fetch the transaction list, which returns a JSON array containing up to 15 recent transactions with fields including hash, from, to, value, timeStamp, and gasUsed. 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. For each new transaction, it checks the to address against a built-in list of known DEX router contracts from Uniswap, SushiSwap, 1inch, 0x, and Curve. It calculates the USD value using a price estimation function that maps token symbols to approximate prices, and determines trade direction by comparing the from address to the watched wallet address. The trade detection system also provides risk assessment: Critical (>5× threshold), High (>3× threshold), or Medium (≥ threshold).

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 trading research 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 trades. It cannot account for token price changes between data fetches. It cannot read transaction history from wallets not visible on Etherscan. It cannot identify DEX interactions not included in the known router list. It cannot detect trades made through aggregators that obscure the router. It cannot provide slippage or price impact analysis. It cannot predict future trading activity or profitability. 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 trade details independently before making any decisions based on the alerts.
