While the bridge on bridge.base.org has been deprecated, there are many bridges that support moving assets between Base and other chains.

For questions, see our FAQ.

​
Programmatic Bridging

See the sample code repository to see how to bridge ETH and ERC-20s from Ethereum to Base.

Double check the token address for ERC-20s You can use any ERC-20 that is supported on the network. You can check what assets are on Base and the corresponding contract address via this hub. Ensure there is an address for base, example. Always test with small amounts to ensure the system is working as expected.

This implementation can only bridge assets to Base. Do not attempt to alter the code to withdraw the assets.
