# Overview

Token transfers represent the movement of assets between addresses on the blockchain.

We track transfers across all major token standards to provide comprehensive coverage of asset movements.

<Info>
  Native gas tokens are represented as
  `0x0000000000000000000000000000000000000000` in the `token_address` in our
  assets schemas.
