# Sell the Yield Token

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

The yield token, or its rebasing form, sold for USDC on Ethereum.

## Overview

- `token`: `USDY` or `rUSDY`; `tokenAmount`: how much is sold, at most 18 digits after the point — for `rUSDY` its balance, sold as whole `USDY` units' worth of shares. At the oracle's price, with a tolerance of 0.1%: when the chain gives less than that, the transaction reverts and the operation is `failed` with `failureCode` `TOKENIZED_ASSETS_PRICE_MOVED`.
- Above the token's smallest redemption. A wallet Aurea signs for is signed and sent at once (`201`, `submitted`, `completed` or `failed`); a wallet its owner signs for gets `steps` to sign and send to [Send Signatures](https://docs.aureahub.com/docs/tok-operation-broadcast.md) within ten minutes (`signingExpiresAt`). `received` is the USDC paid, once completed.
- Takes an `Idempotency-Key`. 10 a minute. User token and the tenant signature ([Calling the Routes](https://docs.aureahub.com/docs/guide-tokenized-assets.md)); for `user`, `owner`, `tenantadmin` and `signer`, for themselves (another role: `403`).

## 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):

The same key with the same request answers with the first answer (`idempotency-replayed: true`) instead of running it again; see [Idempotency](https://docs.aureahub.com/docs/idempotency.md) |

**Request body**

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `isTestnet` | boolean | no | `true` for the test environment; `false` (the default) for production. |
