Crypto today is undeniably multichain—interacting with both EVM and non-EVM ecosystems has become routine. This fluidity exists thanks to a growing stack of protocols focused on fast, low-cost connections across chains. In addition to these connection layers, recent developments have seen a rise in projects focused on user experience, particularly those exploring chain abstraction to simplify multi-chain usage. WalletConnect Network is one such project aiming to improve UX.
While initially a simple connection tool, WalletConnect has evolved into a powerful UX infrastructure layer. Its focus? Making DApp and wallet interactions smoother, especially on smartphones. In an ecosystem still largely optimized for desktop browser extensions, WalletConnect stands out by prioritizing mobile-first design.
