Polygon Gas Station Overlay

WHAT IT DOES

Polygon Gas Station Overlay is a DeFi tool that watches the page for transaction interfaces on Polygon, then monitors the Polygon gas station data in real-time, displays current gas prices (slow, standard, fast) as an overlay on the page, and provides a recommended gas price based on current network conditions and transaction urgency. It queries the connected EVM chain via window.ethereum for current gas prices using eth_gasPrice, optionally queries public Polygon gas station APIs for more granular gas price data, reads the current transaction urgency setting from storage, and displays an overlay with real-time gas prices and recommended fees. The overlay is draggable, auto-refreshes, and can be toggled on/off.

WHERE IT RUNS

This tool operates as a panel within the BotGentz browser extension, available for Chrome, Firefox, Edge, and Brave. It works on any webpage displaying transaction interfaces on Polygon, such as DEX interfaces, NFT minting pages, and DeFi dashboard sites on the Polygon network.

HOW TO USE

Navigate to any page where you may submit transactions on Polygon. Open the BotGentz extension and select Polygon Gas Station Overlay from the tool menu. The panel will appear on the side of your browser. Click the "Connect Wallet" button to connect your EVM wallet (must be on Polygon chain). Toggle the "Show Overlay" switch to enable the gas overlay on the page. The overlay will appear in the corner of the page showing current slow, standard, and fast gas prices, along with a recommended price based on your selected urgency setting. You can customize the urgency (slow/standard/fast), position (top-right, bottom-right, top-left, bottom-left), and enable auto-refresh. Use the "Refresh Gas Prices" button to manually update the overlay or "Hide Overlay" to temporarily remove it.

TECHNICAL SECTION — GAS PRICE AGGREGATION AND RECOMMENDATION

This tool uses a multi-stage pipeline for gas price monitoring. First, it connects to the EVM chain via window.ethereum to read the current gas price using eth_gasPrice, which provides the base fee. Second, it optionally queries public Polygon gas station APIs (gasstation.polygon.technology/v2) for more granular gas price data including slow, standard, and fast priority fees. Third, it aggregates the data from both sources, prioritizing API data when available for more accurate fee estimates. Fourth, it calculates a recommended gas price based on the user's urgency setting: slow (lower cost, longer wait), standard (balanced), or fast (higher cost, faster confirmation). Fifth, it displays the data as a draggable overlay on the page with color-coded values. Sixth, it refreshes the data at a configurable interval (default 15 seconds) to keep the overlay up-to-date with changing network conditions.

THE PANEL

The side panel is designed for seamless integration into your browsing workflow. You can drag it to either side of the window, and it remembers your preferred position per website. It supports snap-to-edge behavior and can be collapsed to a small tab for minimal distraction. The panel is resizable horizontally and vertically, with a minimum width of 280px and maximum of 600px. Pressing the Escape key closes the panel. All settings are saved locally.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension (such as MetaMask) already installed in your browser. It works with EVM-compatible chains, specifically designed for Polygon (chain ID 137). Cannot guarantee real-time gas price accuracy due to API latency. Relies on public gas station APIs which may have rate limits. Some APIs may not reflect the latest Polygon gas prices. Cannot predict future gas price changes. Requires the page to be open for real-time updates. Websites change their transaction page formats frequently, and extraction scripts may need periodic updates. This tool does not store or transmit page content except for the gas queries sent to the EVM network and APIs. No browsing history or personal data is collected or retained.
