Arbitrum and Base are the two largest Layer 2 ecosystems by total value locked, and they keep getting cheaper to move between. Base rollups post data to Ethereum L1, and Ethereum gas prices have ranged from $2 to $15 per transaction, but using a direct L2-to-L2 bridge avoids most of that mainnet cost. This guide compares the top 8 routes from Arbitrum to Base, breaking down gas fees, protocol fees, speed, and output type so you can pick the cheapest option for your transfer.
How L2-to-L2 Bridge Fees Work
Moving assets directly between Arbitrum and Base cuts Ethereum out of the equation. Instead of paying L1 gas, you pay:
Arbitrum gas (~$0.10–$0.50 per transaction)
Base gas (~$0.01–$0.05 per transaction)
Bridge protocol fee (0% to 0.3%, depending on the provider)
Relayer or solver spread (embedded in the rate for intent-based bridges)
The total fee for a $1,000 transfer through most L2-to-L2 bridges falls in the $0.50–$3.00 range, with some routes charging as little as $0.45 regardless of size . The key is finding a bridge that charges a flat fee rather than a percentage.

Step-by-Step: How to Bridge Arbitrum to Base with Low Gas
Here's a practical walkthrough using Across, one of the cheapest and fastest routes:
Connect your wallet. Open across.to and connect a wallet like MetaMask or Rabby. Ensure you're on Arbitrum with enough ETH for gas.
Select source and destination. Choose Arbitrum as the source chain and Base as the destination . Across supports both chains natively.
Pick your token. Select USDC, ETH, or another supported token. The interface will display the fee and estimated arrival time upfront .
Enter the amount and review the quote. Check the total cost—Arbitrum gas + bridge fee + Base gas. On Across, the fill time is ~2 seconds .
Approve and confirm. If this is your first time bridging this token, you'll need to approve the SpokePool contract . Then confirm the main transaction.
Track the transaction. You'll receive a transaction hash to monitor progress. The funds land on Base in ~2 seconds .
Common Mistakes to Avoid
Not comparing routes. Aggregators like Symbiosis or Rhino.fi can find cheaper routes than any single bridge. Taking 30 seconds to compare can save meaningful money on larger transfers .
Bridging ETH through Ethereum mainnet. Some bridges route Arbitrum to Base via Ethereum L1, adding L1 gas fees and 10–20 minutes of waiting. Direct L2-to-L2 bridges avoid this entirely .
Forgetting gas on the destination chain. You need a small amount of ETH on Base to interact with apps after the bridge. Keep at least 0.01 ETH in your Base wallet.
Using percentage-based fees for large transfers. A 0.3% fee on a $10,000 transfer costs $30. A flat fee bridge like Symbiosis (~$0.45) costs significantly less .
