# $USN & $sUSN

<mark style="color:purple;">**Noon**</mark> issues two stablecoin-related tokens. This page explains what each is, how they differ, and how they relate.

{% hint style="info" %}
For the practical question of which to hold, see [Should you hold <mark style="color:violet;">**$USN**</mark> or <mark style="color:violet;">**$sUSN**</mark>?](/2.-usdusn-and-usdsusn/usdusn-or-usdsusn.md).
{% endhint %}

## <mark style="color:violet;">**$USN**</mark>

<mark style="color:violet;">**$USN**</mark> is Noon's **dollar-pegged stablecoin**, designed to hold a value of one US dollar. You can hold it, transfer it, and use it across deployed chains. <mark style="color:violet;">**$USN**</mark> **does not earn yield from the protocol's returns**. <mark style="color:violet;">**$USN**</mark> holders earn rewards, which can translate to <mark style="color:purple;">**Noon**</mark>'s governance token.

<mark style="color:violet;">**$USN**</mark> is backed by a **USD-denominated reserve**. Rather than sitting in cash, that reserve is deployed across diversified, income-generating strategies. This allows the protocol to pass yield to stakers.

The full set of strategies is documented in [**The Yield Engine**](/3.-the-yield-engine/overview.md).

## <mark style="color:violet;">**$sUSN**</mark>

<mark style="color:violet;">**$sUSN**</mark> is **staked** <mark style="color:violet;">**$USN**</mark>. When you stake <mark style="color:violet;">**$USN**</mark>, you receive <mark style="color:violet;">**$sUSN**</mark>. <mark style="color:violet;">**$sUSN**</mark> is the token through which protocol yield accrues over time.

Unstaking <mark style="color:violet;">**$sUSN**</mark> back to <mark style="color:violet;">**$USN**</mark> is subject to a **7 day cooldown**.

Of the protocol's distributable returns, **80%** flows to <mark style="color:violet;">**$sUSN**</mark> holders.

## <mark style="color:$primary;">Deployments</mark>

<mark style="color:violet;">**$USN**</mark> and <mark style="color:violet;">**$sUSN**</mark> are deployed across multiple chains. Always **verify the canonical contract** for your chain on [**Contracts and addresses**](/6.-resources/contract-addresses-and-oracles.md) before interacting.
