About this app
WHAT IT DOES
On-Chain SVG Render Helper watches the current marketplace page for on-chain SVG NFT listings, reads the NFT's contract address and token ID from the page, reads the on-chain SVG data from the contract via eth_call, renders a preview of the SVG image, identifies key visual characteristics and metadata from the SVG, compares against user-defined criteria, and displays alerts with NFT details, SVG preview, visual characteristics, and execution recommendations when matching criteria are detected. The tool scans the page for on-chain SVG NFT listings, reads contract addresses and token IDs, reads SVG data from the contract, renders a preview of the SVG image, identifies visual characteristics like colors and shapes, compares against user-defined criteria, 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 on-chain SVG 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 On-Chain SVG Render Helper panel. Set your visual criteria in the format trait:value (comma-separated, e.g., color:blue,shape:circle) — the tool will search for SVG NFTs with matching visual characteristics. Select your preview size from the dropdown — Small, Medium, or Large — to control the preview image size. 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 "Render SVG" — the tool scans the page for on-chain SVG NFT listings, reads contract addresses and token IDs, reads SVG data from the contract, renders a preview of the SVG image, identifies visual characteristics, compares against your criteria, and displays a comprehensive analysis with preview and recommendations. When matching SVG NFTs are detected, the tool triggers alerts with NFT details and visual characteristics. Click "Refresh" to manually update the SVG analysis.
MECHANISM — ON-CHAIN SVG RENDERING AND VISUAL CHARACTERISTIC EXTRACTION
This tool uses an on-chain SVG rendering engine that reads and displays SVG data from contracts and extracts visual characteristics. The system first connects to window.ethereum and requests the user's wallet address. It scans the page for on-chain SVG NFT listings using DOM selectors for item cards and listing details, extracting contract addresses and token IDs. For each NFT, the tool reads the on-chain SVG data from the contract via eth_call, using the appropriate SVG retrieval function. The tool then renders a preview of the SVG image using a DOM-based renderer, extracting visual characteristics such as colors, shapes, and patterns from the SVG markup. The tool compares each NFT's visual characteristics against the user's criteria, identifying matches. The urgency classification uses a multi-tier system: MATCH (visual characteristics match criteria), PARTIAL MATCH (some characteristics match), or NO MATCH. Recommendations are generated based on the match status, helping users identify on-chain SVG NFTs with their desired visual characteristics.
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 SVG data matches the exact moment of execution due to on-chain latency. It cannot account for contract changes or updates. It cannot read SVG data from contracts not supported by the tool. It cannot verify NFT authenticity or ownership. It cannot predict future visual characteristics or value 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, SVG data, and visual characteristics independently before taking any action based on the dashboard.
