What is Uncap USD (USDU)?
Uncap USD, often referred by its token symbol USDU, is a decentralized finance project centered on a Bitcoin backed stablecoin. It operates as a collateralized debt position protocol primarily built on the Starknet network. The project is designed to serve as a liquidity engine within the emerging Bitcoin finance ecosystem, commonly known as BTCFi. The core function of the protocol allows users to deposit Bitcoin as collateral to mint USDU tokens. Unlike many traditional stablecoins that rely on centralized bank reserves, USDU is over collateralized by Bitcoin and maintains its value through a decentralized redemption mechanism. A key feature of the system is its use of the Liquity v2 architecture, which has been adapted to function with Bitcoin on the Starknet layer two scaling solution. Users who participate in the protocol can set their own interest rates for borrowing. The system is designed to be censorship resistant and trust minimized, meaning there are no centralized administrators who can freeze or blacklist individual token holdings. This makes it a non custodial option for Bitcoin holders who wish to access liquidity without selling their underlying assets. The Uncap ecosystem includes a stability pool which serves as a safety net for the protocol. When liquidations occur, the stability pool covers the debt to ensure the system remains solvent. Participants who provide liquidity to this pool receive a portion of the borrowing interest generated by the protocol as a reward for their contribution. Additionally, the project utilizes a model called Protocol Incentivized Liquidity to distribute a percentage of the borrowing interest to trading pools on decentralized exchanges like Ekubo. The primary objective of Uncap USD is to provide a foundational stable asset for the Bitcoin ecosystem that enables sustainable yield opportunities and decentralized financial services. By leveraging the security of the Bitcoin network and the efficiency of Starknet, the project aims to create a transparent and on chain financial infrastructure for global users. Learn more

Uncap USD (USDU) FAQ
Uncap USD (USDU) is a decentralized, Bitcoin-backed stablecoin operating on the Starknet Layer 2 network. It utilizes a Collateralized Debt Position (CDP) model where users deposit Bitcoin as collateral to mint USDU tokens. Unlike traditional stablecoins, it is governed by code rather than a central entity, offering a transparent and decentralized alternative for users who want to leverage their Bitcoin holdings while maintaining a stable asset.
Users can obtain USDU by depositing Wrapped Bitcoin (WBTC) on the Uncap Finance platform to mint new tokens. Alternatively, it can be acquired through swaps on supported decentralized exchanges within the Starknet ecosystem. To store and manage USDU, you must use a compatible Starknet wallet. Always ensure you are using the correct contract address to safeguard your transactions.
Every USDU token is over-collateralized by Bitcoin, meaning the value of the collateral held in the protocol always exceeds the total supply of USDU in circulation. The peg is maintained through a redemption mechanism. If the market value fluctuates, users can redeem USDU for an equivalent value of Bitcoin directly from the protocol. This creates arbitrage opportunities that help restore the asset's value to its target.
No. A key feature of USDU is its censorship-resistant design. Unlike many centralized stablecoins, Uncap USD has no "blacklist" or "freeze" function. It is built to be decentralized and governed by smart contracts, ensuring that no central authority can block transactions or seize user funds. This provides users with full autonomy over their digital assets.
Users can generate yield by depositing USDU into the protocol's Stability Pool. This pool is essential for maintaining the system's solvency during market volatility. Participants in the pool receive a share of the borrowing interest generated by the protocol. Additionally, they can earn liquidation gains in the form of Bitcoin from under-collateralized positions and participate in protocol-incentivized liquidity rewards on supported decentralized platforms.
The main risk is liquidation due to the volatility of Bitcoin. If the collateral value falls below a specific threshold, the Bitcoin may be liquidated to settle the debt. To manage this, users should maintain a safe collateral ratio. Security-wise, the protocol uses a Stability Pool to automatically absorb debt from insolvent positions, ensuring the supply remains fully backed. The architecture is based on established decentralized models and is overseen by a security council.
