Base supports bridging assets from multiple chains including Ethereum, Solana, and Bitcoin. While the bridge on bridge.base.org has been deprecated, there are many bridges that support moving assets between Base and other chains.

​
Ethereum and Base

​
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.

​
Programmatic Bridging (Ethereum)

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.

​
For Token Issuers

If you have an ERC-20 token deployed on Ethereum and want to enable bridging to Base, use the sample code repository above as a starting point for the standard bridge contracts and get your token listed on the Superchain token list.

​
Solana and Base

The Base-Solana bridge enables bidirectional token transfers and message passing between Base and Solana networks. Key Features:
  • Transfer SOL and SPL tokens between Base and Solana
  • Send arbitrary cross-chain messages
  • Deploy wrapped tokens on either chain
  • Optional auto-relay for instant execution
