The Purpose and Mechanics of Airdrops in Cryptocurrency

19 Feb 2024

Definition of Airdrop

An airdrop in the cryptocurrency world is essentially a free distribution of tokens or coins, directly deposited into the wallets of eligible participants. It's a marketing strategy used by blockchain startups to gain awareness and adoption for their project. Think of it like free samples at a store, but instead of snacks, you're getting a piece of their digital currency.

Purpose of Airdrops

While the core objective of airdrops revolves around promoting a new blockchain project or token, their specific purposes can vary depending on the project's goals and strategies. Here are 4 potential purposes of airdrops:

  1. Reward early adopters and community members: This is a common use case, where airdrops are distributed to users who have engaged with the project early on, like holding specific tokens, participating in testnets, or being active on social media.
  2. Increase brand awareness and reach new audiences: By offering free tokens, airdrops attract new users who might not have been aware of the project otherwise. This can significantly boost its visibility and spread the word about its goals and functionalities.
  3. Encourage specific user actions: Some airdrops might require users to perform specific actions like subscribing to a newsletter, following social media accounts, or completing tasks related to the project's platform. This helps drive engagement and incentivize desired user behavior.
  4. Test and promote new features: Airdrops can be used to distribute tokens related to new features or functionalities within the project's platform. This allows for early testing and feedback from users while incentivizing them to explore the new features.

How Airdrops Work:

Understanding the inner workings of airdrops unveils the intricacies behind this strategy and sheds light on how blockchain projects utilize it for various purposes.

  1. Selection Criteria: Before an airdrop takes place, blockchain projects establish specific criteria to determine who is eligible to receive free tokens. This may include holding a certain amount of a particular cryptocurrency, being an active user of a platform, or participating in specific community activities.
  2. Snapshot: In many cases, a snapshot is taken of the blockchain at a particular block height. This snapshot captures the addresses and balances of eligible participants. The airdrop is then based on this snapshot, ensuring that only qualified individuals receive the free tokens.
  3. Smart Contracts: Smart contracts play a crucial role in executing airdrops. These self-executing contracts are pre-programmed with the conditions of the airdrop, including how many tokens each eligible participant will receive.
  4. Token Distribution: Once the snapshot is taken and smart contracts are set, the distribution process begins. Free tokens are sent directly to the eligible participants' wallets. This automated process ensures a fair and seamless distribution without the need for manual intervention.

Types of Airdrops

There are various types of airdrops, each serving different purposes within the cryptocurrency and blockchain space. Here are some common types of airdrops:

  1. Holder Airdrops: This type of airdrop is distributed to existing holders of a particular cryptocurrency. The more tokens you hold, the more airdrop tokens you receive.
  2. Snapshot Airdrops: It is Based on a snapshot of a blockchain at a specific block height, rewarding holders with tokens proportional to their holdings at that moment.
  3. Fork Airdrops: This occurs when a blockchain undergoes a fork, resulting in the creation of a new cryptocurrency. Holders of the original cryptocurrency often receive an equivalent amount of the new cryptocurrency.
  4. Community Airdrops:  It is aimed at building and engaging a community around a particular project. Tokens are distributed to community members, often in exchange for completing specific tasks or promoting the project on social media.
  5. Exchange Airdrops: Cryptocurrency exchanges sometimes conduct airdrops to attract new users or reward existing ones. Users may receive free tokens for signing up, trading, or meeting specific criteria.

Why Companies Conduct Airdrops

Companies conduct airdrops for a variety of reasons, with the overarching goal being to grow their project and community. Here are some of the main motivations:

  1. Raise Awareness and Attract New Users: Airdrops are a cost-effective way to grab attention and introduce people to a new project, cryptocurrency, or platform. By giving away free tokens, companies can spark interest and encourage people to learn more.
  2. Increase Liquidity and Token Distribution: Distributing tokens through an airdrop helps spread ownership wider and creates a larger pool of holders. This can increase the liquidity of the token, making it easier to buy and sell, and potentially boosting its value.
  3. Build a Community and Incentivize Engagement: Airdrops can be used to attract early adopters and supporters who become part of the project's community. Engaging tasks associated with some airdrops, like social media sharing or attending events, further builds momentum and excitement.
  4. Reward Existing Users and Supporters: Companies might use airdrops to show appreciation to loyal users or early investors.
  5. Market Research and Data Collection: Some airdrops may require users to complete surveys or provide information in exchange for tokens. This allows companies to gather valuable data about their target audience and preferences.
