The Base Goerli Token List
This page is intended for token issuers who already have an ERC-20 contract deployed on Ethereum and would like to enable their token for bridging between Ethereum and Base Goerli testnet using the base bridge web interface.
Adding your token to the list
The steps below explain how to get your token on the Base Goerli Token List which serves as the source of truth for these services:
Step 1: Deploy your token on Base Goerli
Select your preferred bridging framework and use it to deploy an ERC-20 for your token on Base Goerli. We recommend you use the framework provided by Base’s standard bridge contracts, and furthermore deploy your token using the OptimismMintableERC20Factory. Deploying your token on Base Goerli testnet in this manner provides us with guarantees that will smooth the approval process. If you choose a different bridging framework, its interface must be compatible with that of the standard bridge, otherwise it may be difficult for us to support.
Step 2: Submit details for your token
We are using the Superchain token list repository for annotating which tokens are available on Base Goerli. Follow the instructions in this repository and submit a PR containing the required details for your token. You must specify in your token’s data.json file a section for ‘base-goerli’ (please do not specify a ‘base’ section until our mainnet is live). The change you need to submit is particularly simple if your token has already been added to the Optimism token list. For example, this PR shows the change required for cbETH, which was already on Optimism’s token list and relies on the Base standard bridge.
Step 3: Await final approval.
Note that approval is not guaranteed or automatic. All submissions for Base listing are subject to manual review by the Base team.
