Airdrop

What is Airdrop?

An airdrop is the free distribution of cryptocurrency tokens to a large number of wallet addresses. It is primarily used as a marketing and growth strategy to bootstrap communities and reward early users.

How does Airdrop work?

1. A project takes a "snapshot" of blockchain activity at a specific time.
2. Eligibility criteria are defined (e.g., having used a protocol).
3. Eligible addresses are often recorded in a Merkle tree for efficiency.
4. Users visit a website to "claim" their tokens by signing a transaction.
5. The tokens are then transferred from the project's treasury to the user's wallet.

Why does Airdrop matter?

Airdrops help decentralize token ownership and governance from day one. They create a "wealth effect" that encourages loyalty and active participation in a protocol’s ecosystem.

Key features of Airdrop

• Reward for early adopters
• Community bootstrapping tool
• Decentralized token distribution
• Often used for governance tokens
• High potential for volatility post-launch
