How to Prevent NFT Listings on Marketplaces
Description
This guide provides information on preventing users from listing NFTs on secondary marketplaces when using the NFTDrops contract.
Problem
Despite enabling the soulbound functionality, users are still able to list NFTs on Seaport and other secondary marketplaces. However, while they can list, they cannot transfer the NFT due to the soulbound restriction.
Solution
Using Soulbound NFTs
- Enabling the soulbound functionality prevents NFTs from being transferred, effectively blocking sales.
- However, this does not stop users from listing the NFT, as marketplaces do not check for transferability before allowing listings.
Custom Smart Contract Approach
For complete control over NFT listing and trading, consider building a custom contract using the Solidity SDK or modular contracts. Some approaches include:
- Disabling the ERC721 Transfer Function
- Modify the contract to override
transferFromandsafeTransferFrom, preventing transfers.
- Restricting NFT Trading on Marketplaces
- Implement contract restrictions to make NFTs unlistable on marketplaces.

Additional Tips
- Consider implementing restrictions at the contract level rather than relying solely on the marketplace’s compliance.
