 # The Base Token List
 
-This page is intended for token issuers who already have an ERC-20 contract deployed on Ethereum and would like to submit their token for bridging between Ethereum and Base. Base uses the [Optimism Superchain token list](https://github.com/ethereum-optimism/ethereum-optimism.github.io) as a reference for tokens that have been deployed on Base.

 ### Step 2: Submit details for your token
 
-Follow the instructions in the [GitHub repository](https://github.com/ethereum-optimism/ethereum-optimism.github.io) 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-sepolia' and/or ‘base’. 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](https://github.com/ethereum-optimism/ethereum-optimism.github.io/commit/27ab9b2d3388f7feba3a152e0a0748c73d732a68) shows the change required for cbETH, which was already on Optimism's token list and relies on the Base standard bridge.
