Airdrop is a service that allows you to lock up requirement NFTs for a set period of time to receive new NFTs.
For each airdrop pool, the NFTs that need to be locked up for NFT Airdrop may vary, and the reward NFTs for each pool may also vary.
Each pool has a snapshot time, and users can input NFTs to the airdrop pool to participate in the airdrop.
The input NFTs are automatically returned to the user's wallet after the lockup period.
Users can then reuse the returned NFTs back to the airdrop pool to receive new NFTs.
