As Ethereum continues to gain momentum, the demand for faster and more cost-effective transaction solutions grows. Layer 2 scaling solutions like Optimism address this need by offering quicker transactions without compromising Ethereum's security or decentralization.
This guide walks you through the process of bridging Ethereum (ETH) to the Optimism network, enabling you to enjoy lower fees and faster speeds for NFT transactions, DeFi, and more.
Step 1: Choose an Optimism-Compatible Wallet
To bridge ETH to Optimism, you’ll need a wallet that supports the Optimism network. Popular options include:
- MetaMask (Download here)
- Coinbase Wallet
How to Add Optimism to MetaMask:
- Open MetaMask and click the network dropdown.
- Select "Custom RPC".
Enter Optimism’s network details:
- Network Name: Optimism
- RPC URL:
https://mainnet.optimism.io - Chain ID:
10 - Currency Symbol: ETH
- Save and switch to the Optimism network.

Step 2: Deposit ETH into the Optimism Bridge
- Go to the Optimism Gateway.
- Connect your wallet.
- Select the amount of ETH to bridge and confirm the transaction.
Note: Bridging tokens requires paying gas fees on Ethereum’s mainnet.
Step 3: Wait for Confirmation
- Transaction times vary based on network congestion.
- Track progress via the Optimism Gateway or Etherscan.
Once confirmed, your ETH will appear in your Optimism-linked wallet.
Step 4: Transact on Optimism
Use your bridged ETH for:
- NFTs: Trade on OpenSea (Optimism-supported).
- DeFi: Platforms like Uniswap and Synthetix.
- Low-cost transfers: Send tokens with minimal fees.

FAQ
How long does bridging take?
Typically 10–45 minutes, but delays may occur during peak congestion.
Are there fees for bridging?
Yes. You’ll pay Ethereum gas fees for the initial transfer. Optimism transactions cost significantly less.
Can I bridge tokens other than ETH?
Yes! Supported ERC-20 tokens (e.g., USDC, DAI) can also be bridged via the Optimism Gateway.
Is Optimism secure?
Optimism is a rollup, meaning it inherits Ethereum’s security while scaling throughput.
Conclusion
Bridging ETH to Optimism unlocks faster transactions and lower fees—ideal for NFT creators, traders, and DeFi users. Follow these steps to migrate your assets seamlessly.
