1. What is Airdrop?
Airdrop is a popular strategy used by blockchain projects to promote and attract interest from the community. By distributing free tokens or NFT, projects aim to generate attention and engagement from users. This not only enhances the project's potential reach but also boosts trading activity on the blockchain platform.
To receive an airdrop, users may need to complete certain tasks such as holding a specific amount of tokens or participating in project promotional activities on social media platforms.
2. Classification of airdrops
2.1. Retroactive
A retroactive airdrop is a type of token distribution where a project rewards individuals who have supported and contributed to the project in the past. Typically, projects will issue tokens to users who have used their services, participated in the community, or provided feedback to help develop the project.

2.2. Bounty Airdrop
A Bounty Airdrop is a token distribution method in which participants need to complete tasks on the project's social media channels, such as Telegram, Twitter, Facebook, and various other platforms, to meet the participation criteria.
2.3. An airdrop for holders of a specific token
In this form of Airdrop, participants need to hold a certain type of token in their wallet to be eligible for the Airdrop.
3. 12 notable crypto projects for conducting airdrops in 2024

3.1. Scroll: zkEVM Layer 2 on Ethereum

3.3. Renzo Protocol: Liquid Restaking platform on Ethereum
Renzo Protocol is a Liquid Restaking platform operating on Ethereum. Instead of users manually managing LST restaking on EigenLayer and choosing Operators (AVS), Renzo allows users to stake ETH, stETH, or wBETH on its platform. Renzo then automatically restakes on EigenLayer using optimized restaking strategies. This reduces the burden on users in risk management and optimizes benefits from restaking on EigenLayer.
Renzo has introduced a point system for users participating in their platform. Users can earn Renzo ezPoint by:
-
Stake ETH, stETH, or wBETH to mint and hold ezETH (Renzo's native Liquid Restaking Token - nLRT). Each ETH, stETH, or wBETH staked will earn users 200 Renzo ezPoints.
-
Introduce new users who stake ETH on Renzo and receive 10% of the points they earn.

4. FAQs
Q1: Who can participate in an Airdrop?

An airdrop is a marketing tool used by new projects to attract attention from the community and increase awareness about the project. Therefore, any investor can participate in an airdrop as long as they meet the conditions set by the project.
Q2: What is a wallet address when participating in an Airdrop?
When participating in airdrop programs from various projects, it's crucial to prepare a series of wallet addresses across multiple blockchains. For instance, you may need wallet addresses on Avalanche, Ethereum, Solana, and potentially other blockchains depending on the projects you're engaging with.
An important note is to use a separate backup wallet set specifically for participating in airdrops, rather than using your primary wallet. This helps mitigate the risk of asset loss and protects the balance of your main account from any unforeseen risks that may arise during the airdrop participation process.
5. Conclusion
Participating in airdrop projects can bring significant benefits to investors and blockchain users, from increasing assets in wallets to establishing strong relationships with promising projects. The year 2024 promises to be a year full of opportunities for airdrop programs, and carefully selecting which projects to engage with will help investors and users make the most of these opportunities.
