on Ethereum and
on Base are both issued by Circle, so bridging between them is a matter of burning or locking one and getting the other. Across does it in seconds: you deposit on Ethereum and a relayer pays you native
on Base from its own funds, then gets repaid from your deposit.

How It Works

Across quotes a fee when you deposit and takes it out of what arrives. For
that fee is mostly the relayer's gas on Base plus a small charge for the capital it fronts, so it stays around a cent on ordinary amounts. What you mostly pay is Ethereum gas for the deposit itself.
What arrives on Base is Circle's native
, the same token Base apps use, not a wrapped copy.

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. Approve
    for Across, then confirm the deposit. The
    shows up on Base a few seconds later.

Bridge With Plug

Use in App
  1. Reads your wallet address.
  2. Deposits 100
    into Across on Ethereum, to be paid out to that address on Base.
The approval happens inside the same run. The amount you receive on Base is quoted from Across when the plug compiles, not fixed when it was written. Change 100 to the amount you want to move.

What It Costs

We simulated the plug on Ethereum in November 2026.
  • Relayer fee. Across quoted 0.0133
    on 100, so 99.9867 arrives on Base. It estimated the fill at about 2 seconds.
  • Gas. At 0.15 gwei the run's 591,000 gas came to 0.0000898
    , about 17 cents. Ethereum gas moves a lot, so check it before you send.
Across's minimum for
from Ethereum was 0.50.
