Context ∞ RPCs are crucial for the operational functionality of decentralized applications (dApps) and wallets, enabling them to query blockchain data and submit transactions. News concerning RPCs often relates to node infrastructure, network accessibility, and the performance of services that rely on these calls, impacting the user experience and the reliability of the decentralized services they access.
