Superchain Bridges
Superbridge
Superbridge enables you to bridge ETH and other supported assets from Ethereum mainnet (L1) directly to Base.
Supported Networks
Brid.gg
Brid.gg is another option that also helps you bridge ETH and supported assets between Ethereum mainnet (L1) and Base.
Supported Networks
Coinbase Technologies, Inc., provides links to the above independent service providers for your convenience but assumes no responsibility for their operations. Any interactions with these providers are solely between you and the provider.
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 only can bridge assets to Base. Do not attempt to alter the code to withdraw the assets.
