NFT Floor Sweep Buyer

WHAT IT DOES

NFT Floor Sweep Buyer watches the current page for NFT collection floor price data and available listings, then automatically executes purchases of all NFTs listed at or below a user-defined floor price threshold until the target quantity is reached or the spend limit is hit. The tool helps you accumulate NFTs from a collection quickly during favorable market conditions without manual clicking.

WHERE IT RUNS

This tool works on any webpage that displays NFT listings with prices, including NFT marketplaces, collection pages, and launchpad sites. It automatically detects floor price data and available listings 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 collection page with listings. Click the NFT Floor Sweep Buyer icon in your browser toolbar or use the keyboard shortcut (Alt+S). 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 price per NFT in ETH, maximum total spend in ETH, target purchase quantity, and gas price limit. Click "Refresh Market Data" to detect the current floor price and available listings. Click "Execute Sweep" to begin the automated purchase process. The tool will identify all listings at or below your price threshold, verify you have sufficient balance, and execute sequential purchase transactions. Monitor sweep progress in the panel. Click "Stop Sweep" to manually halt the process at any time.

TECHNICAL SECTION — LISTING DETECTION AND SEQUENTIAL PURCHASE ENGINE

Unlike manual purchasing or one-click buy tools, this tool uses a listing detection and sequential purchase engine. It first scans the page's DOM to identify all NFT listings, extracting prices and listing IDs from page elements. The engine then filters listings that fall at or below your configured price threshold, sorts them by price (lowest first), and calculates the total cost. It verifies your wallet balance against the total cost and checks current gas prices against your configured limit. If all checks pass, the engine initiates a sequential purchase loop. Each transaction is submitted via eth_sendTransaction with your configured gas settings. The engine waits for each transaction to complete before proceeding to the next listing, ensuring orderly execution. If any transaction fails, the engine logs the error and continues with the remaining listings. This approach provides reliable, automated floor sweeps while giving you full control over spending limits and target quantities.

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 price per NFT, max total spend, target quantity, gas limit, auto-execute) 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 purchase transactions via your wallet. Always review your settings carefully before executing a sweep. Cannot detect off-platform listings or private sales, cannot execute purchases on marketplaces that require specific API keys or authentication beyond wallet connection, cannot guarantee that the floor price won't increase during the sweep, and cannot predict the total cost including gas for all transactions. Users may be unable to complete the full sweep if other buyers purchase listings during the process. 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.
