NFT Bundle Offer Maker

WHAT IT DOES

NFT Bundle Offer Maker lets you create a single buy offer covering multiple NFTs from the same seller on a supported marketplace. Instead of making individual offers on each NFT—which can be tedious and less attractive to sellers—you bundle them into one offer with a total price. The tool checks that all NFTs are listed by the same seller, validates their listing status, and submits a single bundle offer transaction. This is ideal for collectors who want to purchase multiple items from a single seller in one go, or for sellers who prefer to move multiple assets in a single deal.

HOW TO USE

Connect your EVM wallet and select the network. Enter the marketplace contract address (e.g., OpenSea Seaport, Blur) that supports bundle offers. In the input area, list each NFT you want to include in the bundle using the format: contract,tokenId,price (price in wei—the total offer is the sum of all individual prices). Click "Add NFTs" to load them, then click "Check listings" to verify that all NFTs are currently listed and owned by the same seller—the tool checks ownership and seller consistency. Review the status, then click "Make bundle offer" to submit a single offer for the entire bundle at the total price.

TECHNICAL MECHANISM

The tool first verifies that each NFT is listed by checking ownership of the token and that all NFTs share the same owner (seller). It then computes the total offer price as the sum of the individual prices. It approves the marketplace to escrow the total offer amount (in native currency), then calls the marketplace's bundle offer function—which typically takes the seller address, an array of NFT contracts and token IDs, and the total price. The marketplace creates a single offer that the seller can accept or reject. The tool uses receipt.effectiveGasPrice for accurate gas reporting and provides progress feedback during the process.

WHAT IT CANNOT SEE

This tool cannot create bundle offers for NFTs that are not listed or not owned by the same seller—both conditions are verified before proceeding. It relies on the marketplace supporting bundle offers via its contract interface; marketplaces that do not expose a bundle offer function are not supported. The tool does not handle offers that require additional signatures, whitelisting, or off-chain order books. Gas costs scale with the number of NFTs in the bundle.

PLEASE NOTE

Bundle offers require the marketplace to escrow the total offer amount—ensure you have sufficient native tokens (ETH, BNB, etc.) to cover the full offer. The seller can accept the bundle offer as a whole or reject it. The marketplace contract must be trusted; verify its security and audit status before use. This tool is for EVM chains only and does not support non-EVM networks.
