# List onchain assets

> Lists the onchain assets available to your tenant, which are the assets rewards pay out in and balances are held in. Call it to resolve an `onchain_asset_id` you need for a filter elsewhere. Filter with `chain_id`, `key`, `name`, `symbol`, `asset_address`, `type` and `status`, and page with `page` and `limit`. The response `data` carries `items` alongside `total_count`, `page`, `limit`, `total_pages` and `has_next_page`.
