How to bridge ETH from Ethereum to Base

Base is an Ethereum layer 2 with low fees and a large app ecosystem. ETH on Base is the gas token, so bridging ETH is usually the first step before using apps there.

Bridge ETH to Base

Step by step

  1. Open the Ethereum → Base route in xChange (it pre-selects ETH on both sides).
  2. Enter the amount you want to send. Quotes from several bridges appear within a few seconds.
  3. Compare the routes: amount received, estimated time and the fee breakdown.
  4. Connect your wallet and approve the transaction. Some tokens need a one-time approval first.
  5. Keep the page open until the transfer shows as completed, then check your balance on Base.

Tips

  • If you already hold ETH on another layer 2 (Arbitrum, Optimism), bridging from there is usually much cheaper than from mainnet.
  • Your EVM address is identical on Base, so no new wallet is needed.
  • Fast bridges cost a bit more than slow ones; the quote list lets you pick the trade-off.

Bridges and smart contracts carry risk and transactions cannot be reversed. Start with a small test amount if you are new to this route.

FAQ

How long does it take to bridge ETH from Ethereum to Base?

Usually from under a minute to a few minutes, depending on the bridge you pick. Each quote shows its estimated time.

What fees do I pay?

Network gas on the sending chain, the bridge or DEX fee, LI.FI's 0.25% routing fee and xChange's 0.25% interface fee. All of them are shown in the quote before you confirm.

Does xChange hold my funds?

No. You sign every transaction in your own wallet; xChange never has access to your funds or keys.
