Bridge ETH to Base
Bridging ETH to Base is one of the smoothest moves in crypto: ETH stays ETH, and on Base it's also the gas token, so you land ready to transact with no separate gas to source. Fees on Base are a few cents, and a liquidity bridge completes in well under a couple of minutes.

Four steps, all signed in your own wallet.
- 01
Connect your wallet
Connect inside the bridge box. That's the only place Bridgeline ever asks — this site never sees your keys.
- 02
Pick your token and amount
Choose what you're moving, from which chain to which chain, and how much.
- 03
Review the quote and fee
You approve the exact amount in your own wallet, with the full fee shown. Cancel any time before you sign.
- 04
Confirm and track
Sign the transaction and watch it settle on-chain through LI.FI's audited contracts. Bridgeline is never in the middle.
Getting ETH onto Base
Because Base uses ETH for gas, bridging ETH means you arrive with both your asset and your gas in one token — no need to also acquire a native gas coin. That makes ETH the easiest thing to bridge to Base for a first-timer. If you're coming from Ethereum mainnet, the send transaction there is your main cost; from another L2 it's cheap.
Base is Coinbase's OP-Stack layer 2, so it pairs low fees with the easiest fiat on-ramp of any chain in this set — you can often fund a Base wallet straight from a Coinbase account. It has grown into a hub for consumer apps, an active memecoin scene, and liquidity venues like Aerodrome. Gas is paid in ETH, the same token as Ethereum, so there's no unfamiliar gas token to acquire on arrival.
Stay safe while bridging
- Approve only what you’re bridging. The widget requests finite token approvals by default — there’s no need to grant an unlimited allowance.
- Check the URL every time. Bookmark this site and confirm the address bar before connecting a wallet.
- Start small for a new route. A tiny test transfer confirms everything works before you move the full amount.
Moving a large amount? Consider a hardware wallet
A hardware wallet keeps your private keys offline, so a compromised browser or a malicious approval can’t drain your funds on its own. It’s the single biggest security upgrade for anyone holding meaningful value on-chain.

Bridging ETH to Base
Does my ETH stay ETH on Base?
Yes. ETH bridged to Base is still ETH, and it doubles as the gas token, so you arrive able to transact immediately without acquiring anything else.
What's the cheapest way to bridge ETH to Base?
A liquidity bridge or aggregator. Cost is mostly the gas on the chain you're leaving — a few dollars from Ethereum mainnet, cents from another L2 — plus a small spread. The Base side is cheap.
How long does it take?
Usually well under a couple of minutes on a liquidity bridge; the first confirmation on the chain you're leaving is the main variable.
