interceptor

I developed a comprehensive RPC interception and proxying system using Rust that serves as an intelligent middleware layer capable of extending and enhancing RPC functionality while providing seamless integration with multiple vendor backends.

The system operates by intercepting all incoming JSON RPC calls at the application boundary, giving you complete control over the request lifecycle before it reaches any backend service. This interception mechanism acts as a powerful insertion point where you can inject custom business logic, perform data transformations, implement caching strategies, add authentication and authorization layers, apply rate limiting, or conduct real-time monitoring and logging of all RPC traffic.

I developed a JSON RPC server implementation using Rust that functions as a sophisticated proxy layer for RPC (Remote Procedure Call) traffic. This server acts as an intermediary component that sits between clients making RPC requests and the backend services that handle those requests.The core functionality revolves around intercepting incoming JSON RPC calls from clients and intelligently routing them to one of multiple backend RPC servers. Rather than clients connecting directly to individual backend services, they connect to this single proxy endpoint, which then distributes the workload across multiple backend instances.
