What you get by bridging to Arbitrum
Arbitrum keeps Ethereum's settlement security underneath while dropping the cost of a typical transaction to usually a few cents. It carries the largest DeFi ecosystem of any L2, so most strategies you'd run on mainnet have real depth here. For active traders, that combination — mainnet-grade liquidity at L2 prices — is the main draw.
Common ways to bridge to Arbitrum

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 to Arbitrum
What's the cheapest way to bridge to Arbitrum?
A liquidity bridge or aggregator, and the cost depends mostly on where you start. Coming from another L2 is cheap; coming from Ethereum means paying L1 gas to send the bridge transaction, which can run from about a dollar to well over $20 when mainnet is busy. The Arbitrum side is cheap either way, so it's often worth timing an Ethereum departure for a quieter moment.
Will I get native USDC or the older USDC.e on Arbitrum?
Arbitrum has both and they're easy to confuse. Native USDC is issued directly by Circle and is what most current apps expect; USDC.e is the older bridged version still used in some pools. A good route quotes native USDC — check which one the quote shows before confirming so you don't land holding a version your app won't take.
Why does Arbitrum confirm so quickly?
Its sequencer orders and confirms transactions in well under a second, so your balance appears almost as soon as the bridge releases it. Final settlement back to Ethereum takes longer underneath, but for spending and trading on the L2 the fast confirmation is what matters.
Do I need a new gas token on Arbitrum?
No — Arbitrum One uses ETH for gas, the same as Ethereum. Bridge a little ETH alongside your main asset if you're moving only stablecoins, so your first transaction there doesn't stall.
