Adding the Arbitrum Goerli testnet to your MetaMask wallet is a straightforward process that enables you to interact with decentralized applications (DApps) built on this Ethereum Layer 2 scaling solution. Whether you're a developer testing smart contracts or a user exploring new blockchain projects, connecting MetaMask to Arbitrum Goerli (AGOR) unlocks access to faster and lower-cost transactions. This guide walks you through each step with clear instructions, essential network details, and practical tips.
What Is Arbitrum Goerli (AGOR)?
Arbitrum Goerli is the testnet version of Arbitrum One, designed to simulate real-world conditions for developers building on the Arbitrum ecosystem. It uses the AGOR token as its native currency, which has no monetary value but is crucial for paying gas fees during testing. By connecting your MetaMask wallet to this network, you can deploy contracts, test interactions, and debug applications before going live on the mainnet.

Step-by-Step Guide: Connect MetaMask to Arbitrum Goerli
Step 1: Install MetaMask and Create a Wallet
To begin, ensure you have the MetaMask extension installed in your browser. MetaMask is one of the most widely used crypto wallets, offering seamless integration with Ethereum and EVM-compatible networks like Arbitrum Goerli.
👉 Get started securely with a trusted Web3 platform today.
- Open Google Chrome or any supported browser.
- Visit the official MetaMask website and click Download Now.
- Choose “Install MetaMask for Chrome” and confirm the installation from the Chrome Web Store.
- Once installed, open the extension and select Create a Wallet if you're new, or Import Wallet if restoring from a recovery phrase.
- Follow the prompts to set up a secure password and safely back up your 12-word recovery phrase — this is critical for wallet recovery.
Step 2: Configure MetaMask for Arbitrum Goerli
By default, MetaMask connects to the Ethereum Mainnet. To interact with Arbitrum Goerli, you must manually add the network using specific configuration parameters.
- Open your MetaMask extension.
- Click the network dropdown at the top (e.g., "Ethereum Mainnet").
- Select Add Network, then choose Add a Network Manually.
Enter the following details:
- Network Name: Arbitrum Goerli
- New RPC URL:
https://goerli-rollup.arbitrum.io/rpc - Chain ID:
421613 - Currency Symbol (optional): AGOR
- Block Explorer URL (optional):
https://goerli-rollup-explorer.arbitrum.io
Click Save, and MetaMask will switch to the Arbitrum Goerli network automatically.
💡 Tip: You can use alternative public RPC endpoints such ashttps://arbitrum-goerli.public.blastapi.ioorhttps://endpoints.omniatech.io/v1/arbitrum/goerli/publicfor improved connectivity.
Step 3: Verify Connection to Arbitrum Goerli
After saving the network settings, return to your MetaMask dashboard. You should now see “Arbitrum Goerli” displayed in the network selector. Your balance may appear as zero initially — this is normal since AGOR is a testnet token.
To obtain AGOR tokens for testing:
- Visit a trusted Arbitrum Goerli faucet (such as those provided by developer communities).
- Connect your wallet and request test tokens.
- Once received, your AGOR balance will update in MetaMask.
You are now ready to interact with DApps deployed on the Arbitrum Goerli testnet.
Step 4: Import Custom Tokens (Optional)
If you're working with custom ERC-20 tokens on Arbitrum Goerli, you can import them into MetaMask for easier tracking.
- Obtain the token’s contract address from a reliable source (e.g., GitHub repo or project documentation).
- In MetaMask, scroll down and click Import Tokens under the "Assets" tab.
- Paste the contract address — the token symbol and decimals should auto-populate.
- Click Add Custom Token, then confirm with Import Tokens.
The token will now appear in your wallet balance alongside AGOR.
Frequently Asked Questions
Q: Is Arbitrum Goerli safe to use with MetaMask?
Yes. Arbitrum Goerli is a public testnet maintained by Offchain Labs and is considered secure for development and testing purposes. However, never use sensitive seed phrases or real funds on unknown testnets.
Q: Why can’t I see my AGOR balance after adding the network?
AGOR tokens are not automatically distributed. You need to acquire them via a testnet faucet. Ensure you’re using a legitimate faucet to avoid scams.
Q: Can I switch back to Ethereum Mainnet after adding Arbitrum Goerli?
Absolutely. Simply click the network selector in MetaMask and choose “Ethereum Mainnet” from the list. All added networks remain saved for future use.
Q: Do I need real ETH to use Arbitrum Goerli?
Not directly. However, you’ll need Goerli ETH (test ether) on the Ethereum Goerli network to bridge assets to Arbitrum Goerli. Some faucets provide direct AGOR drops, bypassing this requirement.
Q: What is Chain ID 421613 used for?
Chain ID 421613 uniquely identifies the Arbitrum Goerli network within the Ethereum ecosystem. It ensures transactions are processed on the correct chain and prevents replay attacks.
Why Developers Use Arbitrum Goerli
Arbitrum Goerli plays a vital role in the Ethereum developer workflow. As a Layer 2 rollup, it offers near-instant transaction finality and drastically reduced gas costs compared to the Ethereum mainnet. This makes it ideal for:
- Testing smart contract logic without financial risk
- Simulating user interactions in DApps
- Debugging cross-chain messaging and bridging mechanisms
- Validating front-end integrations with backend services
👉 Explore advanced tools for blockchain developers and testers.
The network closely mirrors the production environment of Arbitrum One, making it an essential sandbox for quality assurance before mainnet deployment.
Final Tips for a Smooth Experience
- Always double-check RPC URLs and Chain IDs when adding networks manually.
- Bookmark official resources like the Arbitrum Goerli Block Explorer for transaction monitoring.
- Keep your MetaMask updated to benefit from security patches and new features.
- Use separate wallets for mainnet and testnet activities to avoid confusion.
With your MetaMask configured for Arbitrum Goerli, you're well-equipped to explore the future of scalable Ethereum applications.
