# Base Protocol

> Explore Base as a chain: connect to its networks, use native primitives, understand transactions and network systems, and operate infrastructure.

Base is an EVM-compatible chain with its own native primitives, transaction pipeline, network configuration, and protocol specification. Use the Base Protocol section to connect to the chain, understand how it works, and operate infrastructure against it.
