Arbitrum Nova is a high-performance Layer 2 (L2) blockchain designed to deliver fast, low-cost transactions while maintaining Ethereum-level security. Built on Arbitrum’s AnyTrust technology and supported by a Data Availability Committee (DAC), it's especially well-suited for decentralized applications in gaming, social platforms, and NFT ecosystems. To interact with this network, users often want to integrate it directly into their MetaMask wallet — and the good news is that doing so is both simple and secure.
Whether you're a developer deploying dApps or a user exploring new blockchain experiences, adding Arbitrum Nova to MetaMask unlocks seamless access to its growing ecosystem. In this guide, we’ll walk you through two reliable methods: using ChainList for automatic configuration and manually entering network details.
Can I Add Arbitrum Nova to MetaMask?
Yes, absolutely. Arbitrum Nova is fully compatible with MetaMask since it operates as an EVM (Ethereum Virtual Machine)-equivalent chain. This means your existing Ethereum wallet can easily connect to the Nova network without needing a separate tool.
By adding Arbitrum Nova, you gain the ability to send ETH, interact with dApps, mint NFTs, and participate in games — all at significantly reduced gas fees compared to Ethereum mainnet. The network leverages off-chain data availability via its DAC, which keeps transaction costs minimal while preserving decentralization and trust.

How to Add Arbitrum Nova to MetaMask Using ChainList
The easiest and most secure way to add Arbitrum Nova is through ChainList, a community-driven directory of verified EVM networks. ChainList connects directly with your MetaMask wallet and automatically applies the correct settings.
Step-by-Step Guide:
- Go to ChainList.org
Open your browser and navigate to ChainList.org. Make sure you're on the official site to avoid phishing risks. - Connect Your MetaMask Wallet
Click the “Connect Wallet” button and choose MetaMask from the options. Confirm the connection in your wallet extension. - Search for Arbitrum Nova
Use the search bar at the top and type "Arbitrum Nova". It should appear quickly in the results. - Add the Network
Click the "Add to MetaMask" button next to Arbitrum Nova. A MetaMask popup will appear showing the network details. - Confirm and Switch Networks
Review the information and click “Next”, then “Add Network”. Once added, you can switch to Arbitrum Nova directly from MetaMask.
This method eliminates manual errors and ensures you’re using officially verified RPC endpoints.
Manual Setup: Arbitrum Nova RPC and Chain ID
If you prefer full control over the setup process, you can manually configure Arbitrum Nova in MetaMask using the official network parameters.
Arbitrum Nova Network Settings
- Network Name: Arbitrum Nova
- New RPC URL:
https://nova.arbitrum.io/rpc - Chain ID:
42170 - Currency Symbol: ETH
- Block Explorer URL:
https://nova-explorer.arbitrum.io
How to Enter These Manually:
- Open your MetaMask extension.
- Click the network dropdown (top left) and select "Add Network".
- Choose "Add a Network Manually".
- Fill in each field with the values listed above.
- Click "Save".
MetaMask will validate the connection. If successful, your network will switch to Arbitrum Nova, and you’ll see your account balance updated accordingly (once you have ETH on Nova).
⚠️ Always double-check URLs and Chain IDs. Entering incorrect details could expose you to scams or failed transactions.
What Is Arbitrum Nova?
Arbitrum Nova is a purpose-built Layer 2 scaling solution developed by Offchain Labs, the team behind the broader Arbitrum ecosystem. Unlike traditional rollups that post all transaction data on-chain, Nova uses the AnyTrust protocol, where data availability is ensured by a decentralized Data Availability Committee (DAC). This allows for lower fees and higher throughput — ideal for applications like:
- On-chain gaming
- Social media dApps
- High-frequency NFT marketplaces
Despite using off-chain data storage, Nova maintains strong security guarantees by allowing users to challenge fraudulent activity. It remains fully compatible with Ethereum smart contracts, enabling developers to port their dApps with minimal changes.
Major supporters like Google Cloud and ConsenSys have contributed infrastructure and development tools, helping solidify Nova’s position as a scalable alternative for mass-market blockchain applications.

Frequently Asked Questions (FAQ)
Q: Is Arbitrum Nova safe to use?
Yes. While Arbitrum Nova relies on a Data Availability Committee (DAC) instead of publishing all data on Ethereum, it still provides fraud-proof mechanisms and inherits Ethereum’s security for dispute resolution. As long as at least one honest DAC member remains, the network stays secure.
Q: Do I need special tokens to use Arbitrum Nova?
No. You use standard ETH as gas on Arbitrum Nova. However, you must bridge ETH from Ethereum or another network first, as native ETH doesn’t automatically transfer across chains.
Q: How do I get ETH on Arbitrum Nova?
You can bridge ETH using official tools like the Arbitrum Bridge or third-party cross-chain bridges. Some exchanges also support direct withdrawals to Arbitrum Nova.
Q: Can I use the same address on Arbitrum Nova as on Ethereum?
Yes. Since it’s EVM-compatible, your MetaMask address works identically on Arbitrum Nova. Just ensure you're sending funds to the correct network.
Q: Are there any risks when adding custom networks?
Only if you enter incorrect RPC URLs or trust unverified sources. Always use official documentation or trusted platforms like ChainList to avoid phishing attacks or loss of funds.
👉 Stay protected with secure wallet practices and trusted exchange integration.
