How to Bridge Ethereum to Base: The Complete Guide (2025)
Back to articles
Imagine driving on a highway where every lane moves smoothly, no congestion or delays. That’s what the Base Layer 2 (L2) network, built by Coinbase, brings to Ethereum transactions: a faster lane that avoids Mainnet’s network congestion, high gas fees, and slow confirmations.
If you’re sending ETH to Base, bridging is an essential step for anyone who wants faster, cheaper transactions and access to new dApps. With Burner’s native support for Base, onboarding your wallet is all it takes—Base is one of the default networks. From there, you’ll just need ETH on Base to start using the chain. The easiest decentralized way to do that is by bridging ETH from another network.
This guide walks through the best ways to bridge ETH to Base, explains the main types of bridges, and highlights common pitfalls to avoid.
What Is Base?
Base is a L2 blockchain that extends Ethereum’s capabilities, offering faster transactions and lower gas fees without sacrificing security or compatibility. Built on Optimism’s OP Stack, it connects seamlessly with the wider Ethereum ecosystem while helping scale it for everyday use. Today, Base powers a vibrant ecosystem of dApps and protocol integrations, making it a key part of the broader Ethereum Superchain.
Key benefits of Base:
- Fast Transactions: Near-instant confirmations.
- Lower Gas Fees: A fraction of Mainnet costs.
- Developer-Friendly: Simplifies building and deploying decentralized applications.

Understanding Bridging in Crypto
Bridging allows you to transfer assets like ETH from one blockchain to another without selling or moving your funds through an exchange. Because most blockchains operate independently, bridges act as the connective layer that makes cross-chain movement possible.
When you bridge ETH from Ethereum to Base, a smart contract locks your tokens on Ethereum and releases equivalent ETH on Base, keeping your balance consistent across both chains. This process has become faster and simpler over time as bridging technology has evolved.
In the past, there were clear categories of tools: dedicated bridge platforms, bridge aggregators, and the protocols that powered them behind the scenes. But as the tech has matured, those lines have blurred. Many decentralized exchanges (DEXs) now integrate bridging directly into their swap interfaces, routing through multiple cross-chain protocols automatically.
For most users today, the main distinction is whether the method is non-custodial, where you stay in control of your assets, or custodial, where an exchange manages the transfer on your behalf.
How to Bridge to Base
Easiest Way to Bridge: BurnerOS Crosschain Swap
If you already have tokens in your Burner wallet on a supported chain, you don’t need to use a separate bridge. BurnerOS lets you swap between chains directly, with transactions routed automatically using 0x’s cross-chain API.
You can conveniently move from any supported token on Ethereum, Optimism, or Arbitrum to any token on Base, all from inside your wallet.
Manual Way to Bridge: Using a Bridging Platform
This is just one example of the bridging process using Superbridge. The steps are nearly identical across most bridge platforms.
1. Open Superbridge and connect your Burner wallet
Go to Superbridge, choose Ethereum → Base, then select WalletConnect and pair your Burner (or any EVM wallet).
2. Enter the Amount
Specify how much ETH you want to bridge. In this example, we’ve selected the Native Bridge option, which will take around 3 minutes to complete.
3. Review and Confirm
- Review both transaction fees and gas fees, then approve the transaction in your wallet.
- Once the bridge begins, you’ll see a wait time countdown as the transfer completes.
- When it’s done, check your Burner wallet on Base to confirm the ETH has arrived.
Types of Bridges
For most users today, the main distinction is whether the method is non-custodial, where you stay in control of your assets, or custodial, where an exchange manages the transfer on your behalf.
Non-Custodial (Decentralized) Bridges
These bridges and decentralized exchanges let you move assets directly from your wallet. Transfers are handled by smart contracts or cross-chain messaging protocols, keeping you in control at all times.

- Matcha (by 0x)
- 1inch
- Portal (by Wormhole)
- deBridge (by Synapse)
Custodial (Exchange-Based) Bridges
Centralized exchanges handle the bridging process for you when you withdraw or deposit crypto between networks. This method is convenient but means the exchange temporarily holds your assets. Access to these exchanges depends on your region and local regulations.
In the United States, the most widely used custodial options include:
In Asia and other global markets, popular options include:
Choosing the Right Blockchain Bridge
Not all bridges and swaps work the same way. Some prioritize speed, others focus on low fees or flexibility. When evaluating your options, consider:
- Custodial vs. Non-Custodial: The most important factor is whether you keep control of your assets.
- Supported tokens: Confirm that the bridge or exchange supports the assets you plan to transfer (ETH, USDC, WETH, etc.).
- Security audits and reputation: Choose platforms that are well-established and have undergone public security audits.
- Transaction speed: Some transfers complete in seconds, while others take several minutes depending on network activity.
- Transaction fees: Review both the bridge service fee and the gas fee required for your transaction.
- Wallet compatibility: Ensure your EVM wallet (such as Burner, MetaMask, or Coinbase Wallet) is supported.
- User experience: Look for clear progress indicators and reliable transaction tracking.
Security & Troubleshooting
Bridges are secure when used correctly, but small mistakes can lead to lost funds. Always verify that you’re using an official, audited site before confirming any transaction.
To stay safe:
- Verify Contract Addresses: Use reputable explorers like BaseScan to confirm the bridge’s contract address.
- Watch for Phishing Sites: Bookmark official URLs instead of relying on search results or social media links.
- Never Share Seed Phrases: No legitimate bridge will ever ask for your private key or recovery phrase.
Note: Since Burner doesn’t use a traditional seed phrase at all, this security risk isn’t a concern. Your keys stay protected inside the device, removing a common crypto phishing threat.
Common Issues and Fixes:
Even when using a reliable bridge, small technical issues can occasionally occur, usually related to gas, network congestion, or transaction settings.
- Insufficient Gas Fees: Always keep a small ETH buffer for gas when bridging.
- Transaction Errors: Try again during a low-congestion period or adjust slippage settings.
- Stuck Transactions: Check the transaction hash on a block explorer before resubmitting to avoid duplicates.
Final Thoguhts
Bridging ETH to Base isn’t just about saving gas—it’s about unlocking a faster, simpler way to use Ethereum. The right blockchain bridge makes that process secure, efficient, and seamless from start to finish.
Once your assets are on Base, Burner makes it easy to explore dApps, manage your funds, and transact quickly across the network. Every transaction feels lighter, faster, and closer to what onchain should be.
FAQ: How to Bridge
❓ What if my bridging transaction fails?
If a bridge transaction fails, your assets usually remain safe. Reputable bridges have safeguards that prevent loss during failed transfers. You can retry the transaction or open a support ticket with the bridge provider if it doesn’t resolve automatically.
❓ Do I need gas to bridge?
Yes. Every bridge transaction requires gas on the origin chain, paid in that chain’s native token (for example ETH on Ethereum, OP on Optimism, ARB on Arbitrum, etc.). You do not need gas on the destination chain beforehand; you only need it on the chain you are bridging from.
❓ Is bridging safe?
Generally, yes. If you use trusted and audited non-custodial blockchain bridges. Always verify URLs, bookmark official sites, and avoid new or unaudited platforms.
❓ Can I use the same wallet for Ethereum and Base?
Yes. Base is fully compatible with EVM wallets such as Burner, MetaMask, Coinbase Wallet, and Rainbow. You’ll use the same wallet address on both Ethereum and Base, but you’ll need to add Base as a network in your wallet.
❓ What happens to my ETH after bridging?
When you bridge ETH to Base, your tokens are locked on Ethereum, and equivalent ETH is issued on Base via a smart contract. It’s still the same ETH—just operating on a faster Layer 2 blockchain. You can bridge it back to Ethereum anytime using a compatible bridge.
❓ Can I bridge stablecoins or other tokens to Base?
Yes. Most bridges support ERC-20 tokens like USDC, DAI, and WETH. Each bridge has its own supported token list, so check compatibility before starting the process. If the token you want to bridge is not supported, you can always swap it into a supported token first and then complete the bridge.
❓ How long does it take to bridge to Base?
Most bridges complete transfers in just a couple of minutes, though timing varies by the specific bridge and the networks involved. Some routes settle in under a minute, while others may take slightly longer to finalize.
❓ Can I bridge directly inside Burner?
Yes. If your tokens are already in a Burner wallet on another chain, you can use BurnerOS crosschain swaps to move them to Base without a separate bridge. This built-in feature acts as both a swap and bridge, letting you go from any token on any supported chain to a token on Base, all within your wallet.
❓ How do I make sure I’m bridging safely? Always use verified links when you bridge crypto. Bookmark trusted platforms, confirm official URLs, and check for a recent security audit. If you’re unsure, verify the contract address on BaseScan before confirming any transaction.
