NFT New Listing Alert

WHAT IT DOES

NFT New Listing Alert watches the current page for NFT listings, maintains a persistent history of observed NFTs, detects when new NFTs appear on the page that were not previously tracked, and triggers alerts with the NFT ID, listing price, and timestamp for monitoring fresh market activity. The tool helps you stay informed about new listings as soon as they appear, enabling timely purchasing decisions.

WHERE IT RUNS

This tool works on any webpage that displays NFT listings with IDs and prices, including NFT marketplaces, collection pages, and trading platforms. It automatically detects listings and tracks their presence over time. The script runs on all websites as designated in its match patterns.

HOW TO USE

After installing the BotGentz extension, navigate to any NFT listing page. Click the NFT New Listing Alert icon in your browser toolbar or use the keyboard shortcut (Alt+N). The panel will open. Click "Connect Wallet" to connect your real EVM wallet extension—this provides network context. Configure the check interval in seconds, minimum price threshold to alert in ETH, and clear history after hours. Toggle desktop notifications and sound alerts on or off. Click "Scan Now" to detect all current listings and start tracking. Click "Start Watching" to enable continuous monitoring. The panel displays a list of tracked listings with their latest prices. When a new listing appears, you receive a desktop notification and sound alert with the NFT ID, price, and timestamp. Use "Stop Watching" to pause monitoring.

TECHNICAL SECTION — LISTING TRACKING AND NEW LISTING DETECTION ENGINE

Unlike simple page refresh tools, this tool uses a listing tracking and new listing detection engine. It first scans the page DOM to detect all NFT listings, extracting IDs and prices from page elements. The engine maintains a persistent history of all observed listings, storing each NFT's ID, price, first seen time, and last seen time. On each scan, the engine compares the current set of visible listings against the history. NFTs that appear in the current scan but were not previously tracked are flagged as new listings. The engine then applies the minimum price filter and triggers multi-channel alerts for qualifying new listings. The alert includes the NFT ID, listing price, and timestamp of detection. This approach provides immediate notification of fresh market activity without requiring external data sources.

THE PANEL

The panel is draggable anywhere on the screen and remembers its position per site. It can snap to the left, right, top, or bottom edges, or float freely. Collapse it to a small status indicator when you need more page visibility, and expand it again with a single click. Resize it vertically or horizontally to show more of the listing history. Press Escape to close the panel instantly. All settings (interval, min price, clear history, notifications, sound) are saved globally and persist across sessions.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension already installed in your browser. EVM chains only—supports Ethereum Mainnet, Polygon, Arbitrum, and Optimism. Wallet connection is read-only; this tool never initiates transactions or signs messages. Cannot detect new listings that appear between page refresh intervals, cannot distinguish between newly listed NFTs and pagination reloads, cannot track NFTs that are not visible on the current page, and cannot detect new listings on pages that use infinite scrolling without proper detection. Users must manually verify new listings before acting on alerts. Websites change their layouts frequently; scripts may need updates, and we work to keep them current but cannot guarantee uninterrupted operation.
