Introduction to DApp Security

Decentralized Applications, or DApps, are applications that run on a blockchain network rather than a centralized server. They often include smart contracts on the back end and an accessible front end for users. Because DApps interact with valuable assets and user data, DApp security is critical to protect both the application and its users from potential risks.

• Why is DApp Security Critical?

  • DApps are often open-source, meaning anyone can inspect their code. While this promotes transparency, it also allows attackers to study the code for vulnerabilities.

  • DApps have both a front end (the user interface) and a back end (often a smart contract on a blockchain). This dual nature introduces unique security challenges that traditional apps don’t face, such as needing to protect both the blockchain-based logic and the user-facing interface.

  • Since DApps handle digital assets, a security breach could lead to financial losses for users and damage to the project’s reputation.
