About this app
WHAT IT DOES
The NFT Sniping Bot scans active listings on NFT marketplace contracts—OpenSea Seaport, Blur, LooksRare, or custom deployments—on Ethereum, Polygon, and Arbitrum. You provide the marketplace contract address, the NFT collection address, a max price, and optionally a specific token ID. The tool fetches live listings, filters by price, and presents the cheapest options. You can then "snipe" the cheapest listing (single purchase) or batch snipe multiple listings in one session. The tool submits the buy transaction(s) through your wallet at the listed price, helping you secure undervalued NFTs before others notice.
HOW TO USE
1. Connect your EVM wallet using the Connect Wallet button.
2. Select your chain: Ethereum (1), Polygon (137), or Arbitrum (42161).
3. Enter the marketplace contract address (e.g., OpenSea Seaport, Blur, LooksRare).
4. Enter the NFT collection address and optional target token ID.
5. Set your max price in ETH.
6. Choose an operation: Scan listings, Snipe (single cheapest), or Batch snipe.
7. For batch snipe, set the number of tokens to buy.
8. Click "Scan listings" to fetch available listings.
9. Review the findings in the review section.
10. Click "Execute" to buy the selected NFT(s).
THE REAL MECHANISM — marketplace listing fetch with price-filtered purchase execution
This tool uses a user-provided marketplace contract address and calls a generic `getActiveListings(address collection, uint256 maxPrice)` view function to fetch token IDs and prices. The user provides the contract address, so they are vouching for its legitimacy. The tool filters listings by price and sorts them from cheapest to most expensive. For the purchase, it uses a `buyItem(address collection, uint256 tokenId)` payable function on the marketplace contract, submitting the exact ETH amount required for each listing. Batch snipe executes multiple buy transactions sequentially, with a small delay between each to avoid nonce conflicts. All transactions are built and submitted through your wallet—no data is stored or transmitted beyond the on-chain calls.
WHAT IT CANNOT SEE
- This tool cannot execute transactions faster than the blockchain's block time (typically 12-15 seconds).
- It cannot guarantee that a listing will still be available at the time of transaction execution.
- It cannot detect listings that are not exposed via the marketplace's standard contract interface.
- It cannot bypass marketplace fees or listing restrictions.
- It does not support NFT marketplaces on chains other than EVM-compatible networks (Ethereum, Polygon, Arbitrum).
- It cannot verify if the marketplace contract is legitimate—you are responsible for checking the address you enter.
PLEASE NOTE
- This tool works on Ethereum (1), Polygon (137), and Arbitrum (42161).
- You must provide the marketplace contract address yourself—this tool does not hardcode any addresses, so you remain in control.
- Sniping is competitive—listings can be bought by others between scan and execution.
- The tool assumes the marketplace contract implements `getActiveListings()` and `buyItem()` with the expected signatures. Different marketplaces may use different interfaces.
- Batch snipe executes multiple transactions in sequence—each one requires gas and confirmation.
- Always review the total cost (price + gas) before executing.
