# Tokens

The `tokens` object represents on-chain tokens tracked and indexed by the Xerberus platform. Each token includes essential metadata such as its symbol, address, and the blockchain (`chain`) it belongs to.

This object is returned by multiple queries including:

* `Query: tokens` — paginated list of all tokens with filters.
* `Query: tokensBySimilarSymbol` — fuzzy search on token symbol.
* `Query: tokensBySimilarAddress` — fuzzy search on token address.
