I have an Atomic wallet I use for transactions. Unfortunately, I never checked the other sections of the wallet to know their functions. I recently checked the NFT section and saw I received several past airdrops but the links to claim them are now dead.
Then, there’s no way to claim it, as airdrops run on script, and there’s a specific time duration for claiming. I missed a lot of airdrops because I lost track of the airdrop I participated in, so I just considered it a loss.
Also, be sure to verify that the airdrop is legit, as many are just a bait to steal coins from your wallet. The most important part of an airdrop is the announcement of the TGE or token generation event, so be sure not to miss it. Some airdrops are automatic, while others require you to complete tasks.
