Relay is the cheapest bridge we checked for moving tokens to Base: its docs list a 0.00% platform fee on token bridges plus a $0.02 execution cost and gas. Once on Base, gas is small: Base's docs set a minimum base fee of 0.005 gwei, about $0.002 for a typical 200,000 gas transaction at an ETH price of $2,000. Base's own docs send Ethereum users to Superbridge or Brid.gg for the native route.
Quick answer
Use Relay or Across for fast, low-fee moves to Base from other chains, Allbridge Core for stablecoins, and withdraw straight to Base from Coinbase if your funds are there.

No audit list in the current docs
Skip it if you want a published fee and audit list: current docs show neither.
Base: Base's docs do not describe a bridge app of their own; they point Ethereum users to Superbridge or Brid.gg and Solana users to the Base-Solana bridge.
hop-protocol: Not operating: its site no longer serves the bridge app when we checked on Sep 26, 2026.
deBridge: Terms exclude US residents: deBridge's terms exclude US persons.
Symbiosis: Terms exclude US residents: Symbiosis's terms exclude US residents, citizens and US-incorporated entities.
TVL on Base: total value locked in the protocol on this chain, from DefiLlama, refreshed daily. A dash means DefiLlama does not track it on Base.
“Not verified” means we could not confirm the value on the project’s own pages.
How we rank Base bridges
01Confirmed on Base: Base must appear in the bridge's own contract list, chain list or API. We did not rely on third-party lists.
02Published fee: the protocol's own fee from its docs, excluding gas. A fee we could not find counts against the bridge.
03Chain coverage: how many networks the bridge's own docs list, which decides where you can bridge from.
04Audits: named auditors on the bridge's own pages.
05Operating status: incidents and product changes the project states in its docs, such as Allbridge's July 2026 change.
No project paid to be listed or ranked. Full rules: methodology.
What we did not test
We did not open accounts, deposit money or place trades with these services.
We did not audit smart contracts, reserves or security claims ourselves; we report what the project and its auditors publish.
Fees, limits and availability change; the list date shows when we last checked them.

How to choose
01
Skip the bridge if you use Coinbase
Base's docs say Coinbase account holders can withdraw ETH, USDC and cbBTC straight to Base by picking Base as the network, with no bridge.
02
Leaving Base for Ethereum takes a week natively
Base's docs say withdrawals to Ethereum wait 7 days under its fault proof system. Across and Relay pay out sooner through relayers.
03
Compare the received amount
Across and Relay show cost as the difference between input and output. Quote the same transfer on two bridges and compare what lands in your wallet.
04
Check the token address
Base's docs tell token holders to confirm an ERC-20 has a Base entry in the Superchain token list before bridging, and to test with small amounts.
Who should skip all of these
Coinbase users with funds already on the exchange: a direct withdrawal to Base is cheaper than any bridge.
Anyone who needs Hop Protocol: it is not operating.
From Coinbase, withdraw directly to Base with no bridge. Among bridges we checked, Relay lists a 0.00% platform fee on token bridges plus a $0.02 execution cost and gas.
