 ## What is Chain Abstraction?
 
 Chain abstraction refers to the process of creating a seamless user experience by masking the complexities of interacting with multiple blockchain networks. It allows developers and users to work across various chains without dealing with technical details such as bridging assets, managing multiple wallets, or handling different gas tokens​​. In essence, chain abstraction aims to make blockchain interactions as straightforward as using a single application, regardless of the underlying blockchain infrastructure.
