Arbitrum RPC nodes

Chain ID	42161
Network name	Arbitrum One (a.k.a. “Arbitrum Mainnet”)
Protocol type	Optimistic roll-up secured by Ethereum
Execution stack	Arbitrum Nitro (Arbitrum Stylus for WASM + EVM)
Native gas token	ETH (same as Ethereum)
Average block time	~0.25 s (batch posted to Ethereum every ~8 min)

Run your own Arbitrum node to tap into Ethereum-level security with roll-up-grade fees. Self-hosted Arbitrum One or Arbitrum Nova RPC endpoints provide full data access, zero rate limits, and faster transaction confirmations for any Web3 project.

Infrastructure scaling options

Full node – Stores the latest Arbitrum state plus a rolling window of recent blocks, so it spins up quickly and syncs in minutes from Nitro snapshots. Ideal for production dApps, wallets, relayers, and bot back-ends that only need up-to-date balances, events, and transaction submission.
Archive node – Keeps every historical state diff and trace from genesis onward, letting you query “what did this address look like at block #12 345 678?” or replay transactions for forensic audits. Perfect for indexers, analytics dashboards, on-chain credit scoring, and back-testing strategies that demand full time-travel reads.

Security and monitoring

Lock down every Arbitrum RPC endpoint with enterprise-grade controls:

IP allowlists – Accept calls only from approved server or edge IPs. One mis-typed address and the request never reaches your node, blocking botnets and shadow APIs at the perimeter.
Origin rules – Enforce CORS and referrer checks to allow only traffic from your production domains to access the endpoint, preventing front-end code injection and hostile iframe drops before they occur.
JWT authentication – Issue short-lived JSON Web Tokens for scripts, back-end jobs, and mobile apps; each token carries a crypto-signed expiry, so even if it leaks it dies quickly and can’t be reused.

Set Slack or Email alerts so you’re the first to know if your Arbitrum node needs attention.

Chainstack Console performance charts – Open any Arbitrum node details page in Console to see API calls activity. Toggle between 1 h, 6 h, 12 h, 24 h, 7 d ranges; hover for exact data points; and download CSVs for deeper BI analysis.
Chainstack Status page alerts – Subscribe to the public status dashboard for instant email, Slack, or webhook notifications on planned maintenance, regional cloud incidents, or unexpected network events, keeping your team and stakeholders in sync without extra monitoring overhead.

SOC2 compliant

Our systems follow SOC2 standards with robust access logging, encryption, and operational oversight.

SSO and role-based access

Integrate with your identity provider via SAML or OIDC, and manage access with RBAC at scale.

Notes for Arbitrum API

When communicating with a Arbitrum RPC node, the Arbitrum client implements a JSON-RPC specification, a communication protocol allowing one to make remote calls and execute them as if they were made locally.

The Arbitrum API allows developers to communicate with the Arbitrum blockchain to build applications. The best way to use the Arbitrum API is to use a web3 library such as ethers.js if using JavaScript or web3.py using Python.
