Real Holder Count Overlay

WHAT IT DOES Real Holder Count Overlay watches the current marketplace page for NFT collection listings, reads the collection's total supply and holder data from the NFT contract via eth_call, calculates the real holder count by filtering out wash trading addresses and suspected bots, analyzes holder distribution patterns to identify concentration risks, and displays an overlay with total holders, real holders, concentration percentage, and execution recommendations when significant holder anomalies are detected. The tool scans the page for collection listings, reads total supply and holder data from the NFT contract, filters out wash trading addresses and suspected bots, calculates real holder count and concentration percentage, and provides recommendations. WHERE IT RUNS The tool runs as a panel inside your browser on OpenSea marketplace pages at https://opensea.io/*. It works on any OpenSea page displaying NFT collection listings. The tool connects to your real EVM wallet extension (MetaMask, WalletConnect, or any wallet injecting window.ethereum) to read on-chain data via eth_call and the ethers library loaded at runtime. No data is sent to any external server; all reads happen directly from the blockchain through your wallet provider. HOW TO USE Install the BotGentz extension, navigate to OpenSea with your wallet connected, and open the Real Holder Count Overlay panel. Set your minimum holder count threshold (default 100) — the tool will flag collections with fewer holders than this. Set your concentration risk threshold percentage (default 20%) — the tool will flag collections where the top holder concentration exceeds this percentage. Choose your alert preference — Panel only, Browser notification, or Both. Toggle "Auto-check on page load" if you want the tool to analyze automatically when you open the panel. Click "Scan Holders" — the tool scans the page for collection listings, reads total supply and holder data from the NFT contract, filters out suspicious addresses, calculates real holder count and concentration percentage, and displays a comprehensive analysis with recommendations. When holder anomalies are detected, the tool triggers alerts with holder count details and concentration percentages. Click "Refresh" to manually update the holder analysis. MECHANISM — REAL HOLDER COUNT DETECTION WITH WASH TRADING AND BOT FILTERING This tool uses a real holder count detection engine that filters out wash trading addresses and suspected bots from holder data. The system first connects to window.ethereum and requests the user's wallet address. It scans the page for collection listings using DOM selectors for item cards and listing details, extracting collection contract addresses. The tool reads the collection's total supply and holder data from the NFT contract via eth_call. It analyzes holder distribution patterns to identify wash trading addresses (addresses that trade with themselves) and suspected bots (addresses with unusual patterns). The real holder count is calculated by subtracting filtered addresses from the total holder count. The concentration percentage is calculated as (topHolderBalance / totalSupply) * 100. The urgency classification uses a multi-tier system: SUSPICIOUS (totalHolders < minHolders OR concentration ≥ threshold), MODERATE (some conditions met), or HEALTHY (conditions not met). Recommendations are generated based on the holder analysis, helping users identify collections with unhealthy holder distribution. THE PANEL The BotGentz panel is fully draggable, allowing you to position it anywhere on your screen without obstructing the OpenSea interface. It includes per-site position memory, so the panel returns to your preferred location each time you visit the marketplace. 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 NFT trading workflow. PLEASE NOTE This tool requires the free BotGentz extension and a real EVM wallet extension (such as MetaMask) already installed in your browser. EVM chains only — currently supports Ethereum mainnet. This is a monitoring and analysis tool only — it does not execute trade transactions automatically. The tool cannot guarantee that the displayed holder data matches the exact moment of execution due to on-chain latency. It cannot account for holder data changes or updates. It cannot read holder data from contracts not supported by the tool. It cannot verify holder authenticity or legitimacy. It cannot predict future holder activity or market trends. It cannot read private wallet information or trading intentions. All blockchain reads are performed directly through your wallet provider; 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 holder data, concentration percentages, and distribution patterns independently before taking any action based on the dashboard.
