# Overnight Tokens+

**Overnight Tokens+** are tokens that represent **USD**, fully collateralized with yield-generating assets. These tokens are **pegged** to the price of the asset they represent and **automatically accrue rewards** by increasing the number of Tokens+ in your wallet.

Overnight offers several **Tokens+**, each fully collateralized with yield-generating assets and pegged to the value of the asset they represent. These include:

* **USD+**
* **xUSD**
* **USDT+**

These tokens automatically accrue rewards by increasing the balance in users' wallets, providing a seamless way to earn yield while maintaining the stability of the underlying asset.

The generated yields are distributed to Tokens+ holders via a [**rebasing mechanism**](/core-concept/yield-mechanism-rebase.md).
