Bridge from Ethereum to Arbitrum
Move USDC, ETH, USDT from Ethereum to Arbitrum at the best available rate.
Typical time — usually well under a few minutes once your Ethereum transaction confirms, though a congested L1 can stretch the wait.
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.
Bridging Ethereum to Arbitrum
Arbitrum One runs the deepest DeFi and perps liquidity of any L2 — GMX, blue-chip pools, and the rest — with gas that usually costs just a few cents. The catch is getting there: the bridge transaction settles on Ethereum mainnet, where gas typically runs anywhere from about a dollar to well over $20 when the network is busy. Once your ETH lands on Arbitrum, confirmations are near-instant and moving around costs almost nothing.
Ethereum mainnet holds the deepest liquidity and most of the stablecoins people rely on, but its gas is the highest in this set — a single swap can run from roughly a dollar to well over $20 when the network is busy. Arbitrum One keeps Ethereum's settlement security underneath while dropping the cost of a typical transaction to usually a few cents. It also carries the deepest DeFi liquidity of any L2, with GMX, Uniswap, and a large perpetuals scene, so most of what you'd run on mainnet has real depth there. For anyone trading actively rather than holding, moving over means gas stops eating into the smaller orders. As of publication it remains one of the most-used destinations for people leaving L1 for cheaper execution.
Ethereum
Source- Gas
- Swap gas is the highest here — often a few dollars, and more when the network is busy.
- Speed
- About 12-second blocks; practical finality in roughly 13 minutes.
- Ecosystem
- The main settlement layer: deepest liquidity, most stablecoins, and the blue-chip DeFi protocols.
Arbitrum
Destination- Gas
- Usually a few cents per swap.
- Speed
- Sub-second confirmations; optimistic-rollup settlement to Ethereum.
- Ecosystem
- The deepest DeFi liquidity of any L2 — perpetuals, GMX, and major DEXs.
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.

Questions about Ethereum → Arbitrum
What does Arbitrum give me that mainnet doesn't, and is the bridge itself cheap?
Arbitrum One has the deepest DeFi liquidity of any L2 — GMX, Uniswap, and a large perpetuals ecosystem — so active strategies have genuine depth there, and once you arrive a typical trade usually costs only a few cents. The catch is the trip out: because you're starting on Ethereum, you pay L1 gas to send the bridge transaction, which can run from roughly a dollar to well over $20 when mainnet is congested. It's often worth timing the bridge for a quieter moment on L1, since the destination side is cheap either way.
Will I get real USDC on Arbitrum, or the bridged USDC.e version?
Arbitrum has two USDC tokens and it's easy to mix them up. Native USDC, issued directly by Circle, is what most newer pools and apps now expect; USDC.e is the older bridged version that still circulates in some DeFi. A liquidity bridge that quotes native USDC hands you the Circle-issued token, while some slower official paths historically delivered USDC.e that you'd then have to swap. Check which one the route shows before you confirm, so you don't land holding a version the app you want won't accept.
Why does the Arbitrum side confirm almost immediately?
Arbitrum One runs a sequencer that orders and confirms transactions in well under a second, which is why your balance can appear on the destination almost as soon as the bridge releases it. That fast confirmation is what your wallet shows and what matters for spending and trading on the L2; final settlement back to Ethereum takes longer underneath. If the sequencer is ever paused, transactions queue rather than fail, so funds wait instead of being lost.
Will I have ETH for gas once I land on Arbitrum?
Arbitrum uses ETH for gas, the same token as mainnet, so if you bridge ETH you're covered from your very first transaction. If you only send a stablecoin like USDC, you'll arrive with nothing to pay fees with — bridge a small amount of ETH alongside it, or pick a route that drops a little gas on arrival. Fees there are usually just a few cents, so a small buffer goes a long way.
How long should the transfer take?
On a liquidity bridge, Ethereum to Arbitrum is usually done in well under a few minutes once your L1 transaction confirms. The slow part is the mainnet leg: Ethereum blocks land around every 12 seconds with practical finality near 13 minutes, and most bridges wait for a few confirmations before releasing funds on Arbitrum. When mainnet is congested the wait stretches, but the delay is almost always on the Ethereum side rather than Arbitrum.
