A new type of non-fungible token (NFT) is gaining popularity in the cryptocurrency world.

Retroactive NFTs are NFTs that serve as a prerequisite to obtain crypto airdrops in the future. In other words, by holding a retroactive NFT, you are guaranteed to receive future airdrops from the project. This concept is similar to staking in proof-of-stake cryptocurrencies.

The main difference is that, with retroactive NFTs, you are not required to do anything other than hold the NFT. This passive income stream is appealing to many investors who are looking for ways to earn cryptocurrency without having to put in much effort.

So far, retroactive NFTs have been launched by only a few projects, including AirSwap and DexTools. It is likely that we will see more projects launch retroactive NFTs in the near future, especially in niches like gambling where it comes handy that NFT keys can bypass KYC.
