infra
The infra crate group runs the operational services around the Base node. It powers the auxiliary binaries that sit beside the main client.

Role in the Architecture
Section titled “Role in the Architecture”The infra crates provide the operational tooling around the core node:
- basectl — A management utility for configuring and inspecting Base nodes. Supports mainnet, sepolia, and devnet configurations.
- based — The Base daemon that orchestrates node services.
- ingress-rpc — An RPC proxy that routed incoming JSON-RPC requests, using Kafka for message queuing. Removed from the workspace on 2026-09-21; the proxy layer is the entry point now, and no crate took the forwarding hop over.
- websocket-proxy — Proxies WebSocket connections for flashblock streaming with Brotli compression.
- mempool-rebroadcaster — Rebroadcasts transactions from the mempool to ensure propagation.
- audit — Archives audit logs for operational monitoring.
- system-tests — Integration and end-to-end tests using Docker Compose.
