bitSmiley is a Bitcoin-native Defi project co-invested by OKX Venture and ABCDE. As the first stablecoin project in the BTC DeFi ecosystem, bitSmiley has innovated in both application design and protocol layers. Its groundbreaking Fintegra framework comprises three main components: a decentralized overcollateralized stablecoin protocol, a native trustless lending protocol, and the on-chain derivatives protocol. bitSmiley will initially introduce bitUSD, a native overcollateralized stablecoin on the Bitcoin blockchain, addressing the lack of stable price-pegging tools. Users can generate bitUSD by overcollateralizing their BTC, allowing participation in all BTC blockchain DeFi protocols. Each bitUSD is backed by overcollateralized BTC, ensuring stability and user asset security through a robust liquidation and repayment system.
