NFT Bid Auto-Placer

WHAT IT DOES

NFT Bid Auto-Placer watches the current page for auction listings and bid buttons, then automatically places bids on NFTs at or below a user-configured maximum bid amount, with optional automatic bid increments when outbid. The tool helps you secure NFT auctions without constant manual monitoring, using configurable limits to control spending.

WHERE IT RUNS

This tool works on any webpage that displays NFT auction listings with bid functionality, including NFT marketplaces, auction platforms, and collection pages. It automatically detects current bid prices and bid buttons from page content. The script runs on all websites as designated in its match patterns.

HOW TO USE

After installing the BotGentz extension, navigate to any NFT auction page. Click the NFT Bid Auto-Placer icon in your browser toolbar or use the keyboard shortcut (Alt+B). The panel will open. Click "Connect Wallet" to connect your real EVM wallet extension—this enables transaction signing, balance checking, and gas price detection. Configure your maximum bid amount in ETH, bid increment amount in ETH, total budget cap, gas price limit, and maximum auto-increment attempts. Toggle auto-increment on outbid on or off. Click "Refresh Auction Data" to detect the current bid price. Click "Start Bidding" to begin automated monitoring and bidding. The tool will automatically place bids when the current price plus your increment is within your limits. If auto-increment is enabled and you are outbid, the tool will automatically place a new bid at the increased price, up to your maximum attempts. Monitor bid status in the panel. Click "Stop Bidding" to manually halt the process at any time.

TECHNICAL SECTION — BID PRICE DETECTION AND AUTO-INCREMENT ENGINE

Unlike simple bid buttons or manual bidding tools, this tool uses a bid price detection and auto-increment engine. It first scans the page DOM to detect the current bid price using multiple strategies—regex pattern matching on the page text, searching for bid-specific labels, and extracting prices from bid-related DOM elements. The engine also identifies bid buttons and auction elements. When bidding is active, the tool calculates the bid amount as the current bid price plus your configured increment. It then verifies that this amount does not exceed your maximum bid, total budget, or wallet balance, and checks that the current gas price is within your configured limit. If all checks pass, the tool submits the bid via eth_sendTransaction. When auto-increment is enabled, the engine continuously monitors the page for price changes. If the current bid price rises above your last placed bid, the tool automatically triggers a new bid cycle with the updated price plus increment. This approach provides reliable automated bidding while maintaining full spending control through configurable limits.

THE PANEL

The panel is draggable anywhere on the screen and remembers its position per site. It can snap to the left, right, top, or bottom edges, or float freely. Collapse it to a small status indicator when you need more page visibility, and expand it again with a single click. Resize it vertically or horizontally to show more details. Press Escape to close the panel instantly. All settings (max bid, bid increment, budget cap, gas limit, auto-increment, max increments) are saved globally and persist across sessions.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension already installed in your browser. EVM chains only—supports Ethereum Mainnet, Polygon, Arbitrum, and Optimism. This tool signs and sends bid transactions via your wallet. Always review your settings carefully before starting a bidding session. Cannot detect last-second bids or auction sniping not visible in page DOM updates, cannot guarantee bid success if other bidders exceed your configured maximum, cannot access off-platform auction data, and cannot place bids on marketplaces that require specific API authentication beyond wallet connection. You may still lose auctions to higher bidders or automated sniper tools. Set conservative limits to avoid unexpected spending. Websites change their layouts frequently; scripts may need updates, and we work to keep them current but cannot guarantee uninterrupted operation.
