Bridge ETH to Optimism
Bridging ETH to Optimism lands your ETH on an OP-Stack rollup where it's also the gas token — so you arrive ready to transact with nothing else to acquire. Fees are a few cents on roughly 2-second blocks.
New to bridging? Move a small test amount first to see how it works — most transfers land in a couple of minutes.
Quotes include a 0.5% service fee that supports Bridgeline. Swaps execute through LI.FI’s audited smart contracts — this site never holds your funds.
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 Optimism
Because Optimism uses ETH for gas, bridged ETH is both your asset and your gas in one token — the easiest thing to bring for a first-timer. Coming from Ethereum, the L1 send is your main cost; from another L2 it's cheap, and a liquidity bridge skips the week-long native rollup exit.
Optimism settles to Ethereum for security while keeping costs low, and it's home to Velodrome and a strong public-goods funding culture through retroactive rewards. Because it shares the OP Stack with Base and others, moving between Superchain chains is familiar and cheap. Gas is paid in ETH, so there's no new token to source.
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 Optimism
Is bridged ETH usable as gas on Optimism?
Yes — Optimism uses ETH for gas, so the ETH you bridge covers both your position and your fees. There's no separate gas token to acquire.
What's the cheapest way to bridge ETH to Optimism?
A liquidity bridge or aggregator. Cost is mostly the gas on the chain you're leaving — a few dollars from Ethereum, cents from another L2 — plus a small spread. The Optimism 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.
