Adding the Optimism network to your MetaMask wallet is a straightforward process that unlocks access to one of the fastest-growing Ethereum Layer 2 scaling solutions. Whether you're looking to reduce gas fees, speed up transactions, or dive into the expanding world of Optimism-based DeFi protocols, integrating this network into your wallet is a crucial first step.
This comprehensive guide walks you through each phase of adding Optimism (OP) to MetaMask with clear, step-by-step instructions. We’ll also cover how to safely transfer OP tokens and avoid common pitfalls during setup.
Why Use Optimism with MetaMask?
Optimism is an Ethereum Layer 2 (L2) solution that uses optimistic rollups to process transactions off-chain while maintaining Ethereum’s security. This means faster and cheaper transactions—often just a fraction of the cost compared to Ethereum mainnet.
MetaMask, as one of the most widely used cryptocurrency wallets, supports multiple blockchains, including Optimism. By adding Optimism to your MetaMask, you gain seamless access to:
- Low-cost swaps and transfers
- High-performance DeFi platforms like Velodrome and Synthetix
- NFT marketplaces such as Opensea (via Optimism)
- Faster bridge experiences from Ethereum mainnet

Step-by-Step: How to Add Optimism to MetaMask
Step 1: Install and Set Up MetaMask
If you haven’t already, download the official MetaMask extension from metamask.io. Avoid third-party sources to prevent phishing risks.
Once downloaded:
- Add the extension to your browser (Chrome, Firefox, Brave, etc.)
- Create a new wallet or import an existing one
- Securely store your 12-word recovery phrase
After setup, you’ll see the MetaMask fox icon in your browser’s top-right corner. Click it to open your wallet dashboard.
Step 2: Open MetaMask Settings
Inside the MetaMask interface:
- Click your profile icon in the upper-right corner
- Select "Settings" from the dropdown menu
This opens a new window where you can customize your wallet preferences.
Step 3: Navigate to Networks
In the Settings menu:
- Go to "Networks"
- You’ll see a list of default networks like Ethereum Mainnet, BSC, and Polygon
To add a new blockchain, click "Add a network" at the bottom of the list.
Enter Optimism Network Details
Manually input the following configuration for the Optimism network:
- Network Name: Optimism
- New RPC URL:
https://mainnet.optimism.io - Chain ID:
10 - Currency Symbol:
OP - Block Explorer URL:
https://optimistic.etherscan.io
Ensure every detail is accurate—especially the Chain ID and RPC URL—to avoid transaction failures or fund loss.
Click "Save" after entering all fields.
You should now see "Optimism" appear in your network dropdown within MetaMask. The current network is displayed at the top of the wallet interface.
FAQ: Common Questions About Adding Optimism
Q: Is it safe to add Optimism to MetaMask?
A: Yes, as long as you use official network details and download MetaMask from the legitimate website. Never share your private keys or seed phrase.
Q: Do I need OP tokens to use the network?
A: Yes, OP is the native token used for gas fees on Optimism. You’ll need some OP to interact with dApps or send transactions.
Q: Can I use the same address on Ethereum and Optimism?
A: Yes—your MetaMask address remains the same across both chains. However, assets aren’t automatically mirrored; you must bridge them using tools like the Optimism Gateway.
Q: What if I send tokens to the wrong network?
A: Sending assets to an unsupported network can result in permanent loss. Always double-check the selected network before confirming any transfer.
Q: Are transaction fees really lower on Optimism?
A: Absolutely. On average, gas fees on Optimism are 5–10x cheaper than Ethereum mainnet, making it ideal for frequent traders and DeFi users.
How to Transfer OP Tokens to Your MetaMask Wallet
Once Optimism is added, you can receive OP tokens directly.
From a Centralized Exchange (e.g., Binance, OKX)
- Log in to your exchange account
- Navigate to Wallet > Withdraw > Cryptocurrency
- Search for OP (Optimism Ethereum)
- Paste your MetaMask public address (click "Copy" in MetaMask)
- Select Optimism as the withdrawal network
⚠️ Critical: If the network isn’t auto-selected, manually choose Optimism (OP). Withdrawing via ERC-20 (Ethereum mainnet) will send funds to Ethereum—not Optimism—and require bridging later.
- Confirm withdrawal amount and complete security verification
- Wait for confirmation (usually under 5 minutes)
Your OP tokens will appear in MetaMask once processed.
👉 Withdraw and manage your OP tokens securely with advanced trading features.
Exploring DeFi and dApps on Optimism
Now that your wallet is set up, explore top decentralized applications on Optimism:
- Velodrome Finance: Leading DEX with liquidity pools and veTokenomics
- Synthetix: Derivatives protocol enabling synthetic asset trading
- Lyra: Options trading platform built for speed and efficiency
- Bedrock: Native staking solution for OP token holders
Connect MetaMask by selecting it when prompted on these platforms. Always verify URLs to avoid fake sites.
Tips for a Smooth Experience
- Use trusted bridges: Move assets from Ethereum to Optimism via the official Optimism Gateway
- Check gas prices: Even though fees are low, monitor them during peak times
- Bookmark explorers: Use optimistic.etherscan.io to track transactions
- Enable testnet mode cautiously: For developers testing on Optimism Goerli, ensure you don't confuse test and mainnet assets
Final Thoughts
Integrating Optimism into MetaMask enhances your Ethereum experience by reducing costs and increasing transaction speed—without sacrificing security. With just a few clicks, you can become part of a thriving Layer 2 ecosystem powering next-generation decentralized applications.
Whether you're swapping tokens, providing liquidity, or collecting NFTs, having Optimism configured in your wallet opens doors to faster, more affordable blockchain interactions.
As Ethereum continues to scale, Layer 2 networks like Optimism are becoming essential tools for every crypto user. Setting them up early gives you a competitive edge in DeFi innovation.
👉 Maximize your crypto potential with fast, secure transactions on a trusted platform.
