Solana RPC Router & Balancer

The Solana RPC Router is a tool designed to efficiently route and balance traffic between regular Solana RPC servers and those that support the DAS API. The router supports simple round-robin and weighted round-robin balancing strategies. Keep in mind that this is just a proof of concept (PoC), but it works.

Usage

make build
./bin/sol-rpc-router -c proxy_config.json

Set up the router behind NGINX or in a Docker container, and use it as a universal endpoint for all your RPC calls within your app.
