What are vampire attacks in crypto?

What is the Ethereum Virtual Machine (EVM)?
  • Vampire attacks in crypto refer to aggressive strategies where a new project, often a fork of an existing one, proposes more appealing conditions to attract users and their liquidity.

  • These attacks primarily target projects that rely heavily on user-provided liquidity, such as decentralized exchanges and yield farms.

  • While not inherently malicious, vampire attacks can result in significant liquidity loss for the targeted project, potentially leading to its downfall.

Understanding Vampire Attacks

In the crypto world, a "vampire attack" refers to a tactic where a new project—often a modification of an existing one—offers better conditions or rewards to attract users from the original project. The goal is to shift their loyalty and the liquidity they contribute to this new venture. This approach is commonly used in the decentralized finance (DeFi) sector, which depends heavily on liquidity provided by users.

The term "vampire attack" comes from the way these new projects drain liquidity from the originals, metaphorically "sucking the life" out of them. It's important to understand that these attacks aren't necessarily scams or malicious. Instead, they are viewed as aggressive, competitive strategies for growth in the cryptocurrency market.

How Do Vampire Attacks Work?

Vampire attacks often target projects that rely heavily on users and the liquidity they provide. These projects include decentralized exchanges (DEXs), automated market makers, nonfungible token marketplaces, and yield farms. The new project conducting the attack will typically propose substantial benefits, such as airdrops and aggressive marketing, to the existing project's community. The goal is to encourage users to consider reallocating their liquidity from the existing project and quickly increase their own liquidity pool.

The Impact of Vampire Attacks

A successful vampire attack in the crypto world can have major effects. The project being targeted might lose a lot of its liquidity, potentially leading to its collapse. Meanwhile, the project launching the attack could quickly gain more users and increase its liquidity pool.

However, it's important to note that not all vampire attacks succeed. Some projects are able to resist these attacks, keeping their users and liquidity intact.

Preventing Vampire Attacks

Preventing vampire attacks can be challenging due to the open and competitive nature of the crypto space. However, projects can take certain measures to protect themselves.

These include continuously innovating and improving their services to retain their user base, proposing competitive conditions and benefits, and maintaining a strong security track record.

Users, on the other hand, should be wary of new projects proposing substantial benefits and should conduct thorough research before considering reallocating their liquidity.

Examples of Vampire Attacks

The crypto space has witnessed several instances of vampire attacks.

One notable example is the attack by SushiSwap on a well-known decentralized exchange in August 2020. SushiSwap, a fork of the aforementioned exchange, managed to attract a significant amount of liquidity away from it by proposing more appealing conditions to users.

However, it's important to note that despite this attack, the targeted exchange managed to recover and continues to be a recognized player in the decentralized exchange sector.
