# Tokens

> Every token we see onchain: the contracts, their transfers, balances and prices.

A token is one contract on one chain: every token we see onchain, far past the assets we curate by hand. `dimensions.tokens` carries an `asset_id` only where a token has been matched to a curated asset; that layer, with issuers and the native-or-bridged split, is [Assets](/docs/catalog/assets/index).

## Tokens and assets

Every table here keys on `token_id`, which is `{token_address}-{chain_id}`. The same instrument issued on two chains is two tokens, and a bridged wrapper of it is a third. Deciding that several tokens are all the same instrument is a judgment somebody has to make, so that grouping lives on the asset layer rather than here.
