How to install Arbitrum full node

Arbitrum RPC is a Nitro node, not a generic Geth fork you start empty. Toolkit requires the snapshot/init step and tracks download percent from the log.

After init, catch-up follows eth_syncing. Sepolia is the public test env in the catalog.

How to install Arbitrum node

Choose mainnet, sepolia in Toolkit, then follow these steps to provision and run a Arbitrum full node.

1. Install the panel and host agent using the documentation, then register the server in the panel.
2. In Add node, select Arbitrum and the required environment.
3. Review the network options, start provisioning, and follow sync status and logs from the node page.

Operate from the panel

After the node is up you manage it in the same UI — Node Config (edit the live files and apply), client updates, restart, logs, public RPC. You do not need SSH to change conf. Install-time choices (snapshot flavor, history window, disk layout) are stored on that node.

FAQ

How do I install Arbitrum full node?

Install the host agent, add the server, then choose Arbitrum and an environment in Add node. Toolkit provisions Nitro (arbitrum-nitro) and tracks sync from the panel.

Can I change the Arbitrum config later?

Yes. Node page → Node Config. Edit and apply; restart from the same page. A different snapshot or history flavor is an Install choice — changing it later usually means wipe and Add node again.

Pruned or light?
