NFT Metadata Freeze Checker

WHAT IT DOES

NFT Metadata Freeze Checker watches the current marketplace page for NFT listings, reads the NFT's contract address and token ID from the page, reads the metadata URI from the contract via eth_call, checks if the metadata is frozen (permanently locked) or mutable, identifies the storage location of the metadata (IPFS, Arweave, HTTP), and displays alerts with NFT details, freeze status, storage location, and execution recommendations when important metadata freeze status is detected. The tool scans the page for NFT listings, reads contract addresses and token IDs, reads metadata URIs from the contract, checks freeze status, identifies storage location from the URI scheme, 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 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 NFT Metadata Freeze Checker panel. Select your freeze status filter from the dropdown — All NFTs, Frozen only, or Mutable only — to control which NFTs are displayed. Select your storage location filter from the dropdown — All storage, IPFS, Arweave, or HTTP — to filter by metadata storage location. 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 "Check Freeze" — the tool scans the page for NFT listings, reads contract addresses and token IDs, reads metadata URIs from the contract, checks freeze status, identifies storage location, and displays a comprehensive analysis with recommendations. When frozen NFTs are detected, the tool triggers alerts with NFT details and freeze status. Click "Refresh" to manually update the freeze analysis.

MECHANISM — NFT METADATA FREEZE DETECTION WITH STORAGE LOCATION IDENTIFICATION

This tool uses an NFT metadata freeze detection engine that reads metadata URIs and checks freeze status from NFT contracts. The system first connects to window.ethereum and requests the user's wallet address. It scans the page for NFT listings using DOM selectors for item cards and listing details, extracting contract addresses and token IDs. For each NFT, the tool reads the metadata URI from the contract via the tokenURI function using eth_call. The tool checks the freeze status by reading the metadata freeze flag from the contract (if available). It identifies the storage location from the URI scheme: ipfs:// for IPFS, ar:// for Arweave, and http:// or https:// for HTTP. The urgency classification uses a multi-tier system: FROZEN (metadata is permanently locked), MUTABLE (metadata can be changed), or UNKNOWN (freeze status not available). Recommendations are generated based on the freeze status, helping users make informed purchasing decisions.

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 browsing 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 purchase transactions automatically. The tool cannot guarantee that the displayed freeze status matches the exact moment of execution due to on-chain latency. It cannot account for contract changes or updates. It cannot read freeze data from contracts that do not implement freeze functionality. It cannot verify NFT authenticity or ownership. It cannot predict future freeze status changes. It cannot read private wallet information or purchasing 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 NFT details, freeze status, and storage location independently before taking any action based on the dashboard.
