# ERA-20 ERA-20 is a new way of generating and sharing digital assets on the ZkSync ERA by utilizing transaction call data. This entirely community-driven protocol, conceived by the Bigint team, empowers anyone to create and use digital assets on the ZkSync network. We are proud to announce that the Indexer we've developed will be open source, enabling anyone to contribute to its development and ensuring everyone has access to the same information. Furthermore, we are committed to developing and maintaining a public API. If you wish to create your own Indexer or application, feel free to reach out to us on our Discord server for guidance. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
