Moving
from Ethereum to Base is the first thing most people do on Base. There are two common ways: Base's own bridge, which takes a few minutes, and an intent bridge like Across, which takes seconds. Both deliver
to the same address on Base.

How Across Bridges

You deposit
into Across's contract on Ethereum and name what you want on Base. A relayer sees the deposit and pays you on Base from its own funds, usually within seconds. Across then repays the relayer from the deposit once it has checked the deposit on Ethereum. You pay a small relayer fee, taken out of the amount that arrives.
On Base, Across pays out
to a regular wallet. If the receiving address is a smart contract wallet, it pays
instead, which unwraps to
one for one.

Bridging By Hand

  1. Open Across's app and connect your wallet.
  2. Pick Ethereum as the origin, Base as the destination, and
    on both sides.
  3. Enter the amount and check the amount you will receive.
  4. Confirm the deposit on Ethereum. The
    shows up on Base a few seconds later.
Base's own bridge works the same way from your side, but you wait a few minutes for the deposit to land on Base.

Bridge With Plug

Use in App
  1. Reads your wallet address.
  2. Deposits 0.1
    into Across on Ethereum, to be paid out to that address on Base.
The amount you receive on Base is quoted from Across when the plug compiles, not fixed when it was written, so it always reflects the current fee. Change 0.1 to the amount you want to move.

What It Costs

We simulated the plug on Ethereum in November 2026.
  • Relayer fee. Across quoted 0.0000115
    on a 0.1
    bridge, about two cents, so 0.0999885 arrives on Base. It estimated the fill at about 2 seconds.
  • Gas. The deposit runs on Ethereum, so that is where most of the cost is. At 0.15 gwei the run's 431,000 gas came to 0.0000655
    , about 13 cents. When Ethereum is busier, gas rises with it.
Across's minimum for
was 0.00026
.
