USDU is an innovative stablecoin backed by Bitcoin, operating via a Collateralized Debt Position (CDP) framework on Starknet. This unique asset is crafted to enhance liquidity options for Bitcoin holders within the decentralized finance (DeFi) landscape. Users can securely deposit their Bitcoin as collateral to mint USDU stablecoins, all while choosing their desired interest rates. The stablecoin is designed to maintain a consistent 1:1 value with the US dollar, thanks to an efficient redemption mechanism.
As a component of the Uncap ecosystem, USDU plays a crucial role in a dual-protocol system that acts as a liquidity engine for Bitcoin finance, often referred to as BTCFi. One of the standout features of USDU is its permissionless liquidation system, which operates through a stability pool. In this model, 75% of the interest generated from borrowing is distributed among stability pool contributors, while the remaining 25% is designated as Protocol Incentivized Liquidity (PIL), which supports USDU trading pools on the Ekubo DEX.
Built upon the Liquity v2 architecture, USDU has been specifically tailored for Bitcoin collateral on Starknet. Its goal is to become a cornerstone asset within the BTCFi ecosystem, delivering a censorship-resistant and trust-minimized stablecoin solution. This framework allows Bitcoin holders to explore sustainable yield opportunities without the need to liquidate their BTC assets, thus preserving their investment while participating in the DeFi space.
