ETH bridge
Bridge ETH across EVM networks
Choose native ETH on the source chain and the destination you want. puddli checks the live route and shows the result before execution.
- native ETH is separate from ERC-20 WETH
- live route availability
- cross-chain swaps when needed
- source-chain gas remains payable in the native token
Native ETH and WETH are different assets
Native ETH pays transaction gas and does not use an ERC-20 contract. WETH is a token contract, so the selected asset changes the balance, approval and route behavior.
- confirm native ETH or WETH
- check the destination asset
- keep native ETH for source gas
Protect the source gas balance
Sending the full native balance can leave the wallet unable to submit the route. The final wallet estimate determines how much ETH must remain for execution.
- recheck gas immediately before signing
- request a fresh quote after changing the amount
- verify minimum received on the destination
Bridge in three clear steps
- Open the prefilled Ethereum ETH to Optimism ETH route.
- Enter an amount that leaves enough ETH for Ethereum gas.
- Review the destination output and sign the current source transaction.
Frequently asked questions
is native ETH different from WETH?
yes. native ETH pays gas and uses the network native asset identifier, while WETH is an ERC-20 token contract.
can i bridge ETH to a chain whose gas token is not ETH?
yes when a provider route is available for the selected destination asset.
why does max not always send the full native balance?
the source transaction needs native gas, so the wallet must retain enough balance to execute the route.
