A gentle introduction to Arbitrum nodes

In order to be able to interact with or build applications on any of the Arbitrum chains, you need access to the corresponding Arbitrum node. Options are:

• You can use third party node providers (see the list here) to get RPC access to fully-managed nodes
• You can run your own Arbitrum node, especially if you want to always know the state of the Arbitrum chain

Here, you can find resources that help you run different types of Arbitrum nodes:

• Step-by-step instructions for running different Arbitrum nodes, including full Nitro node, full Classic node, local dev node, feed relay, and validator
• Step-by-step instructions for how to read the sequencer feed, build the Nitro locally, and run a DAS
