 Blockchain interoperability protocols are important for the Web3 ecosystem and traditional systems that need to interact with different blockchains. These protocols are the foundation for building blockchain abstraction layers, allowing traditional backends and dApps to interact with any blockchain network through a single middleware solution.

 Blockchain interoperability protocols provide the following capabilities:
