# web3-proxy
quick and dirty proxy for ethereum rpcs (or similar)

Signed transactions are sent to the configured private RPC (eden, flashbots, etc.). All other requests are sent to the configured primary RPC (alchemy, moralis, rivet, your own node, or one of many other providers).

```
cargo run -- --help
