This article explores how interoperability technology serves as a foundational element for achieving seamless chain-agnostic experiences and how chain abstraction leverages interoperability solutions to enhance multi-chain interactions. Bungee, originally a bridge aggregator selecting the cheapest, fastest, and most liquid bridges based on user preferences, recognized the critical role of chain abstraction in addressing fragmentation and advancing the Web3 user experience. This led to the development of Socket 2.0, a modular and scalable coordination protocol for chain abstraction, allowing developers to build chain-agnostic applications. While interoperability and chain abstraction are distinct concepts, they are closely intertwined. As chain abstraction solidifies as the next evolutionary step in Web3, interoperability solutions will find new and creative ways to contribute, creating a positive flywheel effect.
