What is Connext?

Connext is a system that lets developers create applications that work across different blockchain platforms. These applications, called crosschain apps or xApps, can handle funds and data across multiple blockchains or systems like rollups simultaneously.

Why Do We Need xApps?

Blockchains need to handle a lot of transactions to be useful for everyone, but they struggle with handling large volumes. To solve this, some transactions and data are moved to parallel systems, like sidechains or rollups. However, this can make using blockchain confusing because users have to deal with different systems. xApps aim to make this process seamless, letting users interact without worrying about the underlying technology, similar to how you use YouTube without thinking about Google's complex systems.

In short, Connext simplifies and secures the way applications interact across different blockchain systems, promoting wider use and integration of blockchain technology.
