Arbitrum Sequencer Fee Overlay

WHAT IT DOES

Arbitrum Sequencer Fee Overlay is a DeFi tool that watches the page for transaction interfaces on Arbitrum, then monitors the Arbitrum sequencer fee data in real-time, displays current fee estimates (slow, standard, fast) as an overlay on the page, and provides a recommended fee based on current network conditions and transaction urgency. It queries the connected EVM chain via window.ethereum for current gas prices using eth_gasPrice, reads the current L1 base fee from the Arbitrum sequencer via chain calls, optionally queries public Arbitrum fee APIs for more granular fee data, reads the current transaction urgency setting from storage, and displays a draggable overlay with fee estimates and a recommended fee.

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 Arbitrum, such as DEX interfaces, NFT minting pages, and DeFi dashboard sites on the Arbitrum network.

HOW TO USE

Navigate to any page where you may submit transactions on Arbitrum. Open the BotGentz extension and select Arbitrum Sequencer Fee 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 Arbitrum chain). Toggle the "Show Overlay" switch to enable the fee overlay on the page. The overlay will appear in the corner of the page showing current slow, standard, and fast fee estimates, along with a recommended fee 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 Fees" button to manually update the overlay or "Hide Overlay" to temporarily remove it.

TECHNICAL SECTION — SEQUENCER FEE AGGREGATION AND RECOMMENDATION

This tool uses a multi-stage pipeline for sequencer fee 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 for Arbitrum transactions. Second, it reads the current L1 base fee from the Arbitrum sequencer, which is a critical component of Arbitrum's fee structure as it reflects the cost of posting data to Ethereum L1. Third, it optionally queries public Arbitrum fee APIs (Arbiscan API) for more granular fee data including slow, standard, and fast priority fee estimates. Fourth, it aggregates the data from both sources, prioritizing API data when available for more accurate fee estimates. Fifth, it calculates a recommended fee based on the user's urgency setting: slow (lower cost, longer wait), standard (balanced), or fast (higher cost, faster confirmation). Sixth, it displays the data as a draggable overlay on the page with color-coded values for each fee level. Seventh, 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 Arbitrum (chain ID 42161). Cannot guarantee real-time fee accuracy due to API latency. Relies on public Arbitrum fee APIs which may have rate limits. Some APIs may not reflect the latest sequencer fees. Cannot predict future fee 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 fee queries sent to the EVM network and APIs. No browsing history or personal data is collected or retained.
