What Does "RPC URL Deprecated" Mean?

To understand the error, you need to grasp the concept of Remote Procedure Calls (RPCs) in blockchain technology. RPCs are a way for wallets, dApps, and developers to interact with various blockchain networks. Each network has specific RPC URLs that act as endpoints for these interactions. When a network updates its infrastructure, it may deprecate old RPC URLs and provide new ones. The "RPC URL Deprecated" error signifies that the RPC URL you're using is no longer valid.
