NFT projects typically distribute airdrop tokens in several ways. The most common method is by rewarding existing NFT holders with tokens based on their ownership, often proportional to the number or rarity of NFTs they hold. Another approach involves community engagement, where tokens are airdropped to users who participate in activities like joining Discord servers, following social media accounts, or completing specific tasks. Some projects use snapshot dates to determine eligibility, distributing tokens to wallets holding certain NFTs or meeting criteria at that time. Airdrops can also target early supporters, such as presale buyers or whitelist members. To ensure fairness, many projects announce airdrop details in advance and use smart contracts for automated, transparent distribution. Users should watch for official announcements to claim tokens, often via project websites or wallets.
