Start with the network and asset
Base and Ethereum maintain separate balances, so a Base asset cannot simply be sent to an Ethereum address without using a compatible route. Select Base as the source and Ethereum as the destination.

How to Bridge from Base to Ethereum.
What to check when moving supported assets from Base back to Ethereum.
Review the live route
Review the destination asset and expected output before signing. Ethereum gas can be materially different from Base gas, so check the route's costs and consider the destination transaction environment.
Complete the transfer carefully
Some routes may use liquidity or a swap rather than a direct canonical bridge. The live quote shows the path currently available.
Practical takeaway
Confirm the recipient address and destination network, then keep the transaction hash for reference. Do not repeat the transaction if the route is still processing.
