An exclusive airdrop only sends crypto to designated wallets. Typically, the recipients have an established history with the project, such as being an active community member or an early supporter of the project.
In September 2020, decentralized exchange (DEX) Uniswap airdropped 400 UNI to every wallet that had interacted with their protocol before a certain date. The governance token gives holders the right to vote on decisions related to the project’s development in the future.
