Multi-Wallet Balance Switcher

WHAT IT DOES

Multi-Wallet Balance Switcher lets you save and switch between multiple wallet addresses directly from any webpage. You can add wallet addresses with optional labels, view the native token balance for each saved address, and click to copy any address to your clipboard instantly. The tool supports multiple EVM chains—Ethereum, Optimism, Arbitrum, Polygon, Base, and others—and fetches balances via RPC through your connected wallet. A dropdown list of saved wallets shows the current balance for each, and a "switch" button sets the active wallet, copying the address for use on the page.

WHERE IT RUNS

This tool runs as a userscript inside the BotGentz extension on any website. It connects directly to your real EVM wallet via window.ethereum—no intermediate bridge. Balance data is fetched from the blockchain using your wallet's provider.

HOW TO USE

Install the script and navigate to any page. Click "Connect Wallet" to link your EVM wallet. Once connected, use the "Add Wallet" section to save addresses with optional labels. The list displays each wallet's balance in the native token (ETH, MATIC, BNB, etc.). Click "Use" on any wallet to set it as active—this copies the address to your clipboard, making it easy to paste into the page. Click the clipboard icon to copy any address without switching. Use the "Refresh" button to update all balances.

TECHNICAL MECHANISM

The tool stores saved wallet addresses and labels in GM_setValue. When you add a wallet, it calls eth_getBalance via your connected wallet's RPC provider to fetch the native token balance. The balance is cached and displayed alongside each wallet. The tool automatically detects the current chain ID and displays the correct token symbol. Switching wallets simply copies the address to the clipboard—no actual wallet switching occurs in the extension. This allows you to quickly use different addresses for forms, inputs, or interactions on the page. The list is rendered dynamically and updates when balances are refreshed.

THE PANEL

The panel can be dragged anywhere on screen, snapped to the edge, resized, collapsed, and closed with Escape. It remembers its position per site and stays out of your way until you need it.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension (e.g., MetaMask) installed in your browser. It is EVM-only and works on Ethereum, Optimism, Arbitrum, Polygon, Base, and other EVM-compatible chains. It cannot display ERC-20 token balances without additional configuration. It does not automatically switch wallets in the extension—it only copies addresses for manual use. Sites change frequently; the script may need updating. No data is collected or stored beyond your own browser settings.
