NFT Spam labels and filtering

Don’t let spam and potential scammy NFTs get in the way of a great Web3 user experience. Mnemonic’s advanced NFT spam detection capabilities enable you to easily flag or filter out spam NFTs on Polygon or Ethereum.

Protect your users and your user experience from spam NFTs

Spam NFTs and potentially scammy collections are a significant problem plaguing NFT collectors and builders alike. Identifying spam (and, often filtering it out) is an important step developers can take to keep users safe from scams while also providing the best possible user experience. That said, it is increasingly difficult to accurately and comprehensively identify spam, especially given how many NFT collections there are and how sophisticated some of the tactics employed by bad actors and spammy collections are today.

Mnemonic’s proprietary spam detection capabilities are powered by machine learning and can detect even the sneakiest of spam NFT collections on Ethereum and Polygon, helping you create safer, even more delightful Web3 user experiences.

Flag spam and potential scams

Help your users steer clear of spam or potential scam NFT collections by flagging NFTs in their wallet. Spam labels are available through Mnemonic’s Wallet Intelligence API and enable you to get all NFTs held by a given wallet or transfers by any given wallet enriched with spam labels.

What is a spam NFT?

Spam is a problem as old as the internet, so it should not be surprising that it’s made its way into Web3. As gas prices plummet, and adoption and participation in Web3 grows, spammy collections and NFTs are following suit. 

A spam NFT is a type of non-fungible token that is often used in a malicious manner. Often, when we use this term it’s in reference to low-quality, fraudulent (i.e. copy-cats), or irrelevant digital assets. Bad actors may create spam for the sole purpose of exploiting or scamming others. Spam NFTs have little to no value and can be used for phishing scams, promotions of spam content/ads, or other malicious activities. It’s imperative for developers to protect users from potentially-dangerous spam NFTs, and to educate users on the importance of performing proper research before making any NFT transactions or engaging with unknown collections.
