Quick Steps to Bridge ETH from Ethereum to Base
In this LinkedIn article, we explain how to bridge assets from Ethereum to Base safely using CrossDEX.space. The guide covers connecting a self-custody wallet, choosing the correct networks and token, checking the route, confirming fees, and verifying the completed transfer.
Here's the short version before we go deeper:
Open a self-custody wallet that supports both the Ethereum and Base networks.
Make sure your ETH is on the Ethereum blockchain and keep enough ETH for Ethereum gas fees.
Visit CrossDEX.space and choose Ethereum as the source chain and Base as the destination chain.
Select ETH as both the sending and receiving asset, then enter the amount and your Base wallet address if required.
Review the quote, exchange rate, routing fees, network costs, minimum received amount, and estimated completion time.
Confirm the bridge transaction in your wallet through CrossDEX.space.
Check your Base wallet after the transaction settles to verify that your bridged ETH has arrived.

Ethereum's mainnet has a well-earned reputation for high fees and network congestion, while Base offers a faster, cheaper Layer 2 experience. But moving assets between these two networks isn't as simple as sending a regular transaction—it requires a bridge.
This guide walks you through 10 straightforward steps to bridge ETH from Ethereum to Base, with practical tips on fees, timing, and troubleshooting. By the end, you'll have your ETH on Base and ready to use in minutes, not hours. We'll cover the most reliable methods and show you how CrossDex (crossdex.space) can simplify the entire process.
What You Need Before You Start
Before diving into the steps, let's cover a few essentials.
What is Base? Base is an Ethereum Layer 2 (L2) network built using Optimism's OP Stack and incubated by Coinbase . Think of it as an express lane that processes transactions faster and at a fraction of the cost of Ethereum's main highway, while remaining fully compatible with Ethereum apps .
What is bridging? A blockchain bridge is infrastructure that enables asset transfers between independent networks that can't communicate directly . When you bridge ETH from Ethereum to Base, the bridge locks your ETH on Ethereum and mints an equivalent amount of native ETH on Base . The ETH on Base is the real deal—you can use it for gas, DeFi, or anything else.
Why bridge to Base? The main drivers are lower gas fees and faster transaction speeds. Base transactions cost pennies compared to Ethereum's dollars, and finality is near-instant .
Prerequisites:
A self-custody wallet like MetaMask or Rabby (connected to both Ethereum and Base networks)
ETH on Ethereum mainnet (you'll need enough to cover gas fees on both chains)
A small amount of ETH on Base for future gas costs (though your bridged ETH will cover this once it arrives)
Step 1: Connect Your Wallet to the Bridge Interface
Open your preferred bridging platform. For this guide, we'll focus on using a decentralized bridge aggregator—this approach finds the best rates and routes across multiple providers.
On CrossDex (crossdex.space), click "Connect Wallet" in the top-right corner. Select your wallet provider (MetaMask, WalletConnect, or supported alternatives) and authorize the connection . Your wallet will ask permission to share its address—this is standard for any dApp interaction.
What to expect: The interface will display your ETH balance on Ethereum once connected.
Step 2: Select Your Networks
In the bridge interface, set:
Source chain: Ethereum
Destination chain: Base
On CrossDex, these options appear as dropdown menus labeled "From" and "To" .
Pro tip: Double-check you've selected the right networks—bridging to the wrong chain is an expensive mistake.
Step 3: Choose ETH as the Asset to Bridge
Select ETH from the token list. On Ethereum, ETH is the native asset (ERC-20 representation on some interfaces). On Base, ETH is also the native currency used for gas .
In this LinkedIn article, we explain how to bridge assets from Ethereum to Base safely using CrossDEX.space. The guide covers connecting a self-custody wallet, choosing the correct networks and token, checking the route, confirming fees, and verifying the completed transfer.
Important: If you're bridging other tokens (USDC, DAI, etc.), make sure Base supports that specific token and that there's sufficient liquidity for your transfer amount . For simplicity, ETH is the most straightforward asset to bridge.
Step 4: Enter the Amount and Review the Quote
Type the amount of ETH you want to transfer. The bridge will display:
Estimated output — how much ETH you'll receive on Base (usually identical to the input)
Gas fees — Ethereum network fee (paid in ETH) + bridge service fee
Estimated time — typically 2–15 minutes depending on the provider
Realistic expectations: Ethereum gas fees fluctuate based on network congestion. If fees are high (above 50 gwei), consider waiting for a quieter period—you could save $10–$50 .
Step 5: Adjust Slippage Settings (Optional)
Slippage tolerance is the maximum price change you're willing to accept. For ETH-to-ETH bridging, slippage is minimal because it's a 1:1 transfer. However, if your bridge also swaps tokens (e.g., USDT on Ethereum to ETH on Base), you'd want 0.5–1% slippage .
Our recommendation: Set slippage to 0.5% for ETH bridging. Setting it to 0% can cause your transaction to fail if there's any price movement during processing .
Step 6: Initiate the Transaction
Click "Bridge" or "Send" to start the process . Your wallet will pop up with a confirmation screen showing:
Total gas cost (Ethereum network fee)
The bridge service fee (varies by provider)
The final amount you'll receive
Review everything carefully—once you confirm, the transaction can't be reversed.
Step 7: Confirm the Transaction in Your Wallet
In your wallet, confirm the transaction. You'll need to approve:
The gas fee (in ETH)
Any contract interactions required by the bridge
What happens next: Your transaction is broadcast to the Ethereum network. The bridge locks your ETH on Ethereum and emits an event that the destination network can process .
Step 8: Wait for Ethereum Confirmation
Ethereum transaction confirmation typically takes 15–60 seconds, depending on gas price and network congestion . You can track progress on Etherscan using the transaction hash provided by your wallet.
Troubleshooting: If the transaction doesn't confirm within 5 minutes, check Etherscan. Your gas price might be too low—you can sometimes speed it up via your wallet's "speed up" feature.
Step 9: Wait for Bridge Processing
After Ethereum confirms, the bridge needs to verify and process the transfer. Most modern bridges complete this within 2–5 minutes .
Pro tip: Fast bridges use a model where relayers front the ETH on Base from their own capital, so you receive funds almost immediately (around 2 seconds in some cases) . Others wait for the full settlement cycle, which can take longer.
Step 10: Verify Your ETH on Base
Switch your wallet network to Base. You should see your ETH balance reflected immediately . The ETH you receive is native to Base—you can use it for gas, DeFi, or any other on-chain activity.

Before bridging

Expected total time: 2–15 minutes under normal conditions . Fast bridges can deliver ETH on Base in under 2 seconds .
Transaction Stuck on Ethereum
Problem: Your transaction shows "pending" for over 10 minutes.
Solution: Check your gas price. If it's below the current network average, use your wallet's speed-up feature to increase gas. On MetaMask, click the transaction → "Speed up" → adjust gas.
ETH Not Showing on Base
Problem: The bridge says complete, but your Base balance hasn't updated.
Solution: Wait 2–3 minutes and refresh. If still missing, check BaseScan with your wallet address. If there's no incoming transaction, contact the bridge's support or check their status page.
Bridge Fee Seems High
Problem: The displayed bridge fee is higher than expected.
Solution: Use a bridge aggregator like CrossDex to compare rates across providers. Different bridges have different fee structures—some charge a flat fee, others take a percentage .
Insufficient Gas on Base
Problem: You bridged ETH but now can't perform transactions because all your Base ETH is locked in a DeFi position.
Solution: Always keep a small buffer of ETH on Base (0.005–0.01 ETH) for gas. If you're completely out, you'll need to bridge more ETH or use a gasless solution.
Wallet Not Connecting
Problem: The bridge interface won't recognize your wallet.
Solution: Make sure your wallet is unlocked and you're on a supported network. Try refreshing the page or using a different browser. CrossDex supports MetaMask, WalletConnect, and other major providers.
