Collection Completion Tracker

WHAT IT DOES

Collection Completion Tracker is your ultimate NFT collection management tool that shows exactly how close you are to completing any NFT collection. It automatically detects collection metadata from marketplace pages, scans your connected wallet for owned NFTs, and calculates your collection completion percentage based on unique NFT ownership. The tool displays a visual completion dashboard showing owned vs missing NFTs, tracks floor prices to estimate the cost of completing your collection, and provides a prioritized acquisition list based on rarity and price. It monitors your collection growth over time with persistent tracking and sends alerts when you reach completion milestones or when floor prices change significantly.

WHERE IT RUNS

This script runs on all major NFT marketplaces including OpenSea (opensea.io), Blur (blur.io), LooksRare (looksrare.org), Zora (zora.co), Rarible (rarible.com), and Foundation (foundation.app). It works on collection pages, user profile pages, and any page displaying NFT metadata with collection information.

HOW TO USE

Install the script through the BotGentz userscript manager. Click "Connect Wallet" to link your EVM wallet extension—the tool uses your wallet address to determine which NFTs you own. Navigate to any NFT collection page on a supported marketplace. The tool automatically detects the collection and scans your wallet for owned NFTs from that collection. The panel displays your completion percentage with a visual progress bar, owned/missing counts, estimated completion cost based on current floor prices, and a list of missing NFTs. Use "Scan Collection" to manually trigger a scan, or enable auto-scan for automatic detection on page load. The "Copy Completion Report" button exports your complete collection data.

PERSISTENT COLLECTION TRACKING ENGINE WITH MILESTONE ALERTS

Unlike simple portfolio viewers that just show what you own, this tool implements a comprehensive collection tracking engine that continuously monitors your collection progress over time. The engine extracts collection metadata including total supply and trait definitions from marketplace pages using adaptive DOM selectors, then queries your wallet to determine which specific NFTs you own. It calculates completion percentage using set-based comparison (owned count ÷ total supply × 100) and tracks this metric across sessions with persistent storage. The milestone alert system monitors your progress against configurable thresholds (default 25%, 50%, 75%, 90%, 100%) and sends notifications when you reach each milestone. The floor price tracking module monitors current floor prices and estimates completion costs using a weighted average model that accounts for rarity premiums. Acquisition recommendations are prioritized using a combination of rarity rank and current price, helping you identify the most efficient next purchases to increase your completion percentage.

THE PANEL

The floating panel is fully draggable and snap-to-edge enabled. You can collapse it to a compact bubble when not in use, resize it to your preferred dimensions, and it remembers its position across page loads using persistent storage. Press Escape to quickly dismiss the panel. The panel displays your completion percentage with visual progress bar, owned vs missing counts, floor price, estimated completion cost, missing NFT IDs, and historical progress data.

PLEASE NOTE

This script requires the free BotGentz extension to be installed in your browser—it does not run as a standalone extension. You also need a real EVM wallet extension already installed and configured for NFT ownership verification. The tool cannot track NFTs owned before script installation without a full wallet scan and relies on the collection page exposing metadata in a detectable format. Floor price estimates may be inaccurate due to market volatility and should be used as approximations only. No user data is collected or transmitted—all completion data and history stay local in your browser storage. The tool provides visual assistance for collection building but does not constitute investment advice.
