# An Asset's Reserves

> Coming soon, upon request — this feature is turned on for your tenant by the Aurea team. [Contact us](https://www.aureahub.com/contact)

The shares of the underlying held for the tokens in circulation, by custodian, as last attested.

## Overview

- `sharesHeld` against `circulatingSupply`, with each custodian's `holdings`; `reserves` is `null` when none is published. Kept five minutes.
- For the assets the issuer issues and redeems directly (those with `details` in [Get an Asset](https://docs.aureahub.com/docs/tok-asset-get.md)); any other asset answers `409` `TOKENIZED_ASSETS_NOT_SUPPORTED_FOR_ASSET`.
- User token and the tenant signature ([Calling the Routes](https://docs.aureahub.com/docs/guide-tokenized-assets.md)); every tenant role may call it.

## Errors

Besides [the answers every tokenized assets route can give](https://docs.aureahub.com/docs/guide-tokenized-assets.md) (no valid token or signature, the module not set up or not switched on, a field that does not fit):

| Status | details.code | When |
| --- | --- | --- |
| 404 | TOKENIZED_ASSETS_ASSET_NOT_OFFERED | Your tenant does not offer this symbol in this environment (`This tenant does not offer this asset.`). |
| 409 | TOKENIZED_ASSETS_NOT_SUPPORTED_FOR_ASSET | An asset without this data (`This is not available for this asset.`). |
| 503 | TOKENIZED_ASSETS_PROVIDER_… | The issuer's data could not be read ([Provider Errors](https://docs.aureahub.com/docs/guide-tokenized-assets.md)); in the test environment, `TOKENIZED_ASSETS_PROVIDER_UNAVAILABLE` today. |
