An airdrop is the process of distributing tokens or cryptocurrencies to users for free. Airdrops are often used by blockchain projects as a way to promote their project and increase awareness among potential users.

Airdrops can also be used to distribute tokens to existing users as a reward for their support or participation in the project. They are typically distributed to users who hold a specific cryptocurrency, or have interacted with the project in some way.

Airdropped tokens are typically received by users in their cryptocurrency wallet, and can be traded or used on the project's platform.
