# Base

## ETH <-> Base

Bridging on Base is very similar to bridging on zkSync. To bridge tokens from ETH to Base, select the `deposit` tab and enter the amount of ETH to bridge. And to bridge from Base to ETH, select the withdraw tab and input the amount to bridge.

There are multiple bridge for Base chain, any of them can be used to bridge assets between ETH <-> BASE.

### Withdraw

Withdrawing the funds from Base chain to Ethereum is similar to depositing but it takes about 7 days to receive token on Ethereum. According to the Base docs, it's a security feature designed to help secure Base. If you prefer not to wait, you can alternatively use a third-party bridge which allows you to transfer assets much faster.
