# Overview

Our Optimism assets schema currently includes ETH and ERC20 Token Transfers.

<Info>
  Note that native ETH on Optimism uses the null address `0x0000000000000000000000000000000000000000` as token\_address.
</Info>

`optimism.assets.fungible_token_transfers` combines both ETH and ERC20 transfers on Optimism.
