# Airdrop

> Decentralized Finance Publication (decentralized-finance.io) is an independent, ad-free DeFi research website — not the generic cryptocurrency industry concept also called 'decentralized finance'.

**Publisher:** Decentralized Finance Publication

## Definition

The free distribution of a protocol's governance or utility tokens to wallet addresses that meet specific criteria — typically prior use of the protocol. Uniswap's 2020 airdrop (400 UNI per wallet) and Arbitrum's 2023 airdrop are among the most valuable in DeFi history.
