Dutch Auction Mint Price Tracker

WHAT IT DOES

Dutch Auction Mint Price Tracker watches the current page for Dutch auction mint activity, reads the current mint price from the auction contract via eth_call at regular intervals, tracks the price decay over time, and triggers alerts when the price drops below user-defined thresholds, with a visual price chart showing the decay curve and historical mint prices. It helps you find the optimal mint price in Dutch auctions without constantly refreshing the page.

WHERE IT RUNS

This tool operates as a userscript within the BotGentz extension framework, running directly in your browser on any website. It works on any EVM-compatible blockchain page—Ethereum, Polygon, Arbitrum, Optimism, and more—where Dutch auction contracts are deployed. The tool integrates seamlessly into your workflow, appearing as a draggable panel that stays accessible as you monitor auction prices.

HOW TO USE

Enter the Dutch auction contract address and the price function name (e.g., "getPrice", "currentPrice") in the "Contract Setup" section. Optionally, set the starting price, ending price, and auction duration to help visualize the decay curve. Configure your alert thresholds in the "Alert Thresholds" section by entering comma-separated price values in ETH. Set the refresh interval and toggle desktop notifications on or off. Click "Connect & Start Tracking" to connect your real wallet extension, which will begin reading the mint price at your specified interval. The panel displays the current price, a visual decay chart, and triggers notifications when price thresholds are crossed. Use "Refresh Now" for an immediate update, "Clear History" to reset the chart, or "Stop Tracking" to disconnect.

TECHNICAL OPERATION

Dutch Auction Mint Price Tracker uses raw JSON-RPC calls via window.ethereum.request() to interact with the blockchain. It loads ethers at runtime using a simple script tag injection for ABI encoding and contract interactions. The tool reads the current mint price using eth_call with the user-specified price function. It attempts multiple common function names (getPrice, getCurrentPrice, currentPrice, mintPrice, price) as fallbacks. The tool stores price history in memory (up to 100 points) and renders a visual chart showing the price decay curve. It compares the current price against user-defined thresholds and triggers notifications when thresholds are crossed, tracking alerted states to avoid duplicate notifications. The chart displays the price history, threshold lines, and the current price with clear visual indicators.

THE PANEL

The Dutch Auction Mint Price Tracker panel is fully draggable and remembers its position between sessions using GM_setValue. It snaps to the edge of the viewport for a clean interface and can be collapsed to a small icon when not in use. The panel is resizable to accommodate longer content. Press Escape to quickly close or collapse the panel. The design is optimized for productivity with a dark theme, clear visual hierarchy, and responsive controls that adapt to your workflow.

PLEASE NOTE

This tool requires the free BotGentz extension installed in your browser and a real EVM wallet extension (MetaMask, Rabby, etc.) already installed. EVM chains only—this does not work on non-EVM blockchains. The tool cannot read the mint price if the contract does not expose a view function for it, cannot predict future price drops beyond the contract's parameters, cannot detect off-chain auction activity, and cannot monitor auctions that do not use a standard Dutch auction mechanism. No private keys are stored or transmitted—all data is read-only from the blockchain. Always verify the contract address and price function before starting tracking.
