Base Bridge (Testnet)

The Base Bridge for testnet allows you to bridge ETH and certain ERC-20s from Ethereum Sepolia to Base Sepolia and vice versa.

To bridge to or from Base Sepolia:

  1. Visit Base Bridge
  2. Click Connect wallet
  3. Connect your wallet
  4. Choose the amount of ETH (or the asset of your choice that's available) you'd like to deposit or withdraw

Programmatic Bridging

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

:::caution

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 Sepolia and the corresponding contract address via this hub. Ensure there is an address for base-sepolia, example. Always test with small amounts to ensure the system is working as expected.

:::

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