Bridge from Ethereum to Base
Pay ETH on Ethereum and receive Ether (ETH) on Base.
Keep ETH on Ethereum for gas. Enter an amount to compare quotes, then connect your wallet to review and sign.

ETH on Ethereum to ETH on Base
This selection moves funds from Ethereum (chain ID 1) to Base (chain ID 8453). The destination token arrives on Base. Changing a token or network in the swap box changes the route.

- Gas and approvals
- Keep ETH on Ethereum for network fees. ETH is the native asset here, so spending it does not need an ERC-20 approval. Leave some behind for gas. To spend the received ETH later on Base, you will need ETH there for gas.
- Compare an executable quote
- Disconnected previews request current provider quotes but cannot be signed. Reference-price tables are separate from those quotes. Connect your wallet to get transaction details for your address. Review the provider, fees, recipient and minimum received for your amount before signing.

Ethereum to Base: ETH output and fee examples
Captured . These recorded quotes are not executable and do not update with the swap box. They show what the API returned for three amounts at 0.5% slippage. Request a fresh quote above before deciding to swap.
| Input ETH | Provider | Expected ETH | Minimum ETH | Source gas (USD) |
|---|---|---|---|---|
| 0.01 | 0x | No quote returned in this capture | ||
| 0.01 | Relay | 0.00997691 | 0.00992702 | $0.0152 |
| 0.1 | 0x | No quote returned in this capture | ||

Output already reflects route fees. Source gas is paid separately; do not subtract route fees from the output a second time. Missing quotes do not establish that a provider never supports this route. Unknown fee components are not treated as zero.

We sent one disconnected preview request per amount to SwapRoute’s public quote API, which queries capable providers in parallel. No wallet was connected and no trade was executed. An absent route can reflect liquidity, errors, access or a timeout; the response does not distinguish those causes. These observations do not measure settlement speed or establish a consistently cheaper provider.

Verify what arrives on Base
- Confirm that the output in the quote is native ETH on Base, chain ID 8453. Native ETH has no ERC-20 contract; WETH would be a different selection.
- Check the recipient address against the wallet you will open on Base. An Ethereum balance at the same address is separate.
- After the source transaction confirms, follow destination settlement in Activity. Check the destination transaction on BaseScan and the native ETH balance in your wallet.

What to review before bridging to Base
Compare the expected ETH output and minimum received on Base. Keep ETH for separately paid source gas and check any bridge or provider fees. A route with more output does not necessarily have the lowest total cost after gas.
SwapRoute requests quotes from capable 0x and Relay integrations in parallel. Returned routes are ranked by net token output; provider confidence only breaks effectively equal outputs. Speed is not part of the ranking. Availability can change with the amount and market conditions.
FAQ
Ethereum to Base bridge — FAQ
How do I bridge from Ethereum to Base?
Choose Ethereum as the source chain and Base as the destination chain, enter an amount, then review the best available route before signing in your wallet.
How long does a Ethereum to Base bridge take?
Timing depends on provider liquidity and conditions on Ethereum and Base. A provider's estimate is not a measured completion time or a guarantee. Track the destination transaction; source-chain confirmation alone does not confirm arrival.
Can I send bridged funds to a different wallet?
You can request a different recipient on the destination network when the provider supports it. ETH/WETH wrapping can require the connected wallet as recipient. Verify the destination network and address before signing.
Does SwapRoute custody funds while bridging?
No. SwapRoute is non-custodial. You connect your wallet, review the transaction, and sign directly. Execution is handled by the underlying route provider and protocols.
