What is a crypto airdrop?
DefinitionA crypto airdrop is a distribution of free tokens to many wallet addresses, used by projects to reward early users, spread ownership or promote a launch. Real airdrops exist, but fake ones are among the most common ways scammers try to empty wallets.
How airdrops work
A project decides who qualifies, for example addresses that used its app before a certain date or held a certain token, and then either sends tokens directly or lets eligible users claim them. Claiming usually means connecting a wallet to the project’s site and signing a transaction.
- Retroactive airdrops reward past use of a product
- Holder airdrops go to people holding a specific coin or token
- Task-based airdrops reward actions such as testing an app
Fake airdrops and how they steal funds
Scammers send worthless tokens to thousands of addresses, with a name or note pointing to a website where you can supposedly claim or swap them. The site asks you to connect your wallet and sign something that actually lets it move your real tokens, or it asks for your recovery phrase.
- Unknown tokens that appear in your wallet with a website in their name
- Tiny transfers from addresses that look like ones you used before, a trick called address poisoning
- Sites that ask for your recovery phrase to check eligibility
- Countdown pressure such as “claim within 24 hours or lose it”
How to stay safe
- Ignore tokens you didn’t expect; don’t try to sell, swap or send them
- Get airdrop details only from the project’s official channels
- Never enter your recovery phrase anywhere to claim anything
- Read what a transaction does before you sign, especially token approvals
- If you claim airdrops often, use a separate wallet with little in it
