# USD0

## Overview

USD0 is a USD-pegged stablecoin designed for secure and seamless use across the DeFi ecosystem. It is fully backed by US Treasury Bill tokens, offering enhanced security without reliance on traditional banks. The coin is permissionless and easily integrable, with real-time reserve transparency provided by fund administrators. USD0 consolidates liquidity from diverse sources and utilizes an innovative mint engine for efficient collateralization, ensuring peg stability and compliance with US and EU regulations, making it a reliable alternative to USDC and USDT.

<summary><strong>How to Mint USD0</strong></summary>

USD0 tokens can be minted through Usual's counter in two ways:

1. **Direct Mint:** By depositing an eligible RWA into the protocol to receive an equivalent amount of USD0 on a 1:1 basis.
2. **Indirect Mint**: By depositing USDC into the protocol to receive USD0 on a 1:1 basis. In this method, a third party known as the Collateral Provider (CP) supplies the necessary RWA collateral, enabling users to obtain USD0 without directly holding RWAs.&#x20;

<summary><strong>How to Redeem USD0</strong></summary>

USD0 tokens can be redeemed in two ways:

1. **Withdrawal of Underlying Assets**: Users can withdraw the Real World Asset (RWA) underlying the USD0 token directly with the Usual dApp
2. **Secondary Market Transactions**: Users can sell USD0 for USDC/T on the secondary market. As USD0 is fully redeemable within Usual's dApp, the 1:1 peg is expected to be maintained through arbitrage, similar to other fiat backed stablecoins.
