Base Network Bridge Helper

WHAT IT DOES

Base Network Bridge Helper is a DeFi tool that watches the page for bridge interfaces, transfer forms, or cross-chain transaction pages involving Base network, then automatically detects the source and destination chains, estimates gas costs for both chains, calculates the optimal bridge route with estimated fees and time, and displays a helpful summary with one-click action to execute or complete the bridge transaction. It scans the page for bridge interface elements, reads the current chain ID from the connected EVM wallet via window.ethereum, queries the connected EVM chain for gas prices and transaction estimates, optionally queries public bridge APIs for route recommendations, and executes the bridge transaction through the page's existing interface.

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 bridge interfaces, transfer forms, or cross-chain transaction pages. Common sources include bridge aggregators (Across, Hop, Connext), DEX interfaces with bridge functionality, and cross-chain transaction pages.

HOW TO USE

Navigate to any page that displays a bridge interface or cross-chain transfer form. Open the BotGentz extension and select Base Network Bridge Helper from the tool menu. The panel will appear on the side of your browser. Click the "Connect Wallet" button to connect your EVM wallet. Click the "Detect Bridge Interface" button to detect bridge elements on the page. Click the "Analyze Bridge & Get Route" button to analyze the current page state, detect source and destination chains, estimate gas costs, and calculate the optimal bridge route with estimated fees and time. A summary overlay will appear showing the detected chains, amount, estimated fees, gas costs, and total estimated cost. Click "Execute Bridge" to complete the transaction or "Cancel" to abort.

TECHNICAL SECTION — BRIDGE INTERFACE DETECTION AND ROUTE OPTIMIZATION

This tool uses a multi-stage pipeline for bridge interface detection and route optimization. First, it scans the page DOM for bridge interface elements including chain selectors (detecting chain names in select options), amount inputs, recipient address inputs, and bridge action buttons. Second, it connects to the EVM chain via window.ethereum to read the current chain ID using eth_chainId, verifying the user is on the correct chain and enabling gas price queries via eth_gasPrice. Third, it detects the source chain (from the page or wallet) and destination chain (from the page interface). Fourth, it estimates gas costs for both chains using the effectiveGasPrice approach for post-EIP-1559 accurate calculation. Fifth, it calculates an optimal bridge route by combining estimated fees, gas costs, and estimated completion time (5-25 minutes typical for cross-chain bridges). Sixth, it displays a summary overlay showing all detected parameters, estimated costs, and route details. Seventh, upon user confirmation, it populates the amount input using React-compatible value setting (native setter + input/change events) and clicks the bridge button to execute the transaction.

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 (Ethereum, Optimism, Arbitrum, Polygon, Base, etc.). Cannot guarantee bridge route accuracy if using third-party API estimates. Relies on the page exposing bridge interface elements in a detectable format. Some bridge interfaces may have non-standard or dynamic elements. Cannot predict bridge transaction completion times. Requires the page to be open and focused for bridge execution. Does not guarantee bridge success if contract changes or network issues occur. Websites change their bridge page formats frequently, and extraction scripts may need periodic updates. This tool does not store or transmit page content except for the address and gas queries sent to the EVM network. No browsing history or personal data is collected or retained.
