Submission Details
Severity:
Add to denylist function
Summary
NFT thefts have increased recently, so with the addition of hacked NFTs to the platform, NFTs can be converted into liquidity. To prevent this, I recommend adding the denylist function.
Marketplaces such as Opensea have a denylist feature that will not list NFTs that have been reported theft, NFT projects such as Manifold have denylist functions in their smart contracts.
Here is the project example; Manifold
[Manifold Contract] (https://etherscan.io/address/0xe4e4003afe3765aca8149a82fc064c0b125b9e5a#code)
modifier nonDenylistRequired(address extension) {
require(!_denylistedExtensions.contains(extension), "Extension denylisted");
_;
}
