To gain DeFi airdrop eligibility by providing liquidity, users should follow these steps: First, identify DeFi protocols likely to issue airdrops, often announced on their official websites or social media. Next, choose a supported liquidity pool and stake assets, typically by depositing token pairs into a decentralized exchange (DEX) like Uniswap or SushiSwap. Ensure you use a compatible wallet, such as MetaMask, and connect it to the protocol. After depositing, you’ll receive liquidity provider (LP) tokens representing your stake. Hold these tokens as protocols often reward long-term liquidity providers. Monitor eligibility criteria, such as minimum stake duration or amount, via project announcements. Finally, claim the airdrop when distributed, usually through the protocol’s interface. Always verify the project’s legitimacy to avoid scams and check gas fees before transactions.
