Following LooksRare example, X2Y2 is a new NFT marketplace project that is doing a free airdrop to attract its users. In the case of x2y2, that Snapshot date included December 2021 so I finally had a chance to be eligible.
In order to claim your $X2Y2 tokens, you need to go to the Bulk listing tab and list one of your NFTs for sale. Some collections may be marked with a flag that indicates that they don't qualify to airdrop requirements for the trading volume.
Before listing, you would need to approve your collection and that includes a gas fee. The gas is also required in order to claim your tokens as always. This option will appear right after listing and you will also have a chance to choose between claiming and claiming & staking your tokens. Staking would require higher gas fees which is important to keep in mind.
I only got around 5$ worth of tokens and spent around 15$ with gas fees but that was a worth testing experience for me in any case. $X2Y2 tokens can be added to your Metamask wallet with one click afterwards as well.
X2Y2 project is aiming to exit into a DAO at the end and offers its tokens to NFT traders similarly to LooksRare.
