# EarnUSDT

> SuperEarn's yield-bearing USDT shares on Kaia.

EarnUSDT is SuperEarn's yield-bearing USDT share position on Kaia.\
Each EarnUSDT represents a share of the SuperEarn stablecoin portfolio, which is aggregated in the **Super Vault** and deployed across Kaia-native and multichain strategies.

From a user or integrator’s perspective, EarnUSDT represents shares that naturally accrue value over time.

***

## Overview

When a user deposits Kaia USDT through the SuperEarn app (via **SuperEarnRouter**):

* Funds enter the **Cooldown Vault** (not directly callable by users), which enforces withdrawal cooldowns and loss limits.
* In return, the user receives **EarnUSDT** shares that track their pro‑rata share of the overall SuperEarn portfolio.
* Behind the scenes, this portfolio is managed by the **Super Vault** and its connected cross‑chain vaults; users see a single share balance and a single yield stream.

You can think of EarnUSDT as one share position that bundles many strategies: lending, RWA, and other risk‑managed positions, without users needing to handle any of those integrations directly.

## Value Accrual Model

EarnUSDT uses a **price‑per‑share** model instead of rebasing balances:

* Your **EarnUSDT share balance stays constant** in your wallet.
* As the underlying portfolio earns yield, the **USDT value of each EarnUSDT** increases.
* This is reflected in the share price (vault assets ÷ total shares), which is determined by the SuperEarn vault stack.

On deposit:

* The user receives EarnUSDT based on the current exchange rate.
* Example: deposit 1,000 USDT → receive \~1,000 EarnUSDT (exact amount depends on the current share price).

Over time:

* If the portfolio earns yield, **1 EarnUSDT** may later be redeemable for, say, **1.03 USDT**, subject to protocol policies and loss limits.

This model makes EarnUSDT:

* Easy to integrate through the documented Super Vault share flow,
* Easy to account for (no rebasing), and
* Naturally composable with other DeFi protocols.

## Lifecycle: Mint → Use → Redeem

**Mint**

* Deposit Kaia USDT via the SuperEarn interface or by integrating with the protocol.
* The protocol mints EarnUSDT shares to the depositor at the current price‑per‑share.

**Use**

* Hold EarnUSDT shares to accrue yield.
* Use EarnUSDT shares in compatible DeFi integrations when those integrations explicitly support the Super Vault share model.
* Track your position: most portfolio and wallet UIs can treat EarnUSDT like “interest‑bearing USDT”.

**Redeem**

* To exit, users return EarnUSDT through the SuperEarn withdrawal flow via **SuperEarnRouter** (no direct user calls to CooldownVault).
* EarnUSDT shares are burned, and the user receives Kaia USDT based on the latest share price.
* Redemptions are subject to protocol‑level rules:
  * **cooldown periods**,
  * **liquidity management**, and
  * **loss‑limiting / risk controls** in the vault stack.

For the detailed mechanics of how the vaults source and manage liquidity for redemptions, see the [Super Vault](https://docs.superearn.io/en/protocol/supervault) and [How SuperEarn Works](https://docs.superearn.io/en/protocol/how-superearn-works) pages.

## Integrations

EarnUSDT is designed to be:

* **Composable** – compatible with integrations that support the Super Vault share flow.
* **Portfolio‑backed** – each share represents a claim on a diversified, risk‑managed stablecoin portfolio.
* **Chain‑local** – on Kaia, it behaves like a normal Kaia‑native asset.

For exact contract addresses and integration examples, see the [Integrate EarnUSDT](https://docs.superearn.io/en/developers/integrate-earn-usdt) docs in the Developers section.

## Risk Considerations

Holding or integrating EarnUSDT exposes users to the risks of the SuperEarn architecture and its underlying strategies, including:

* Smart contract risk in SuperEarn and integrated DeFi/RWA protocols
* Counterparty and credit risk where RWAs or off‑chain components are involved
* Liquidity and slippage risk during large redemptions or market stress
* Operational and messaging risk around bridging and cross‑chain execution

External protocols that integrate EarnUSDT are encouraged to surface these points in their own documentation and user interfaces.
