Wing is a decentralized platform rooted in credit, designed to facilitate crypto-asset lending and cross-chain communication among decentralized finance (DeFi) projects. Its primary objective is to foster inclusivity in crypto lending services through a credit evaluation module that eliminates the necessity for significant collaterals. As a decentralized autonomous organization (DAO), Wing empowers users to engage in decision-making, product design, and operational aspects. Employing decentralized governance alongside a risk control mechanism, Wing endeavors to enhance the relationships among creditors, borrowers, and guarantors. This approach has resulted in an expansion in the number of DeFi projects utilizing the platform, thereby enhancing accessibility. An overarching aim of Wing DAO is to address the issue of over-collateralization prevalent in the DeFi sector. The platform facilitates the establishment of new blockchain projects and prioritizes the cultivation of a decentralized and autonomous governing community. In response to challenges encountered by other DeFi initiatives, Wing DAO has developed a credit-based DeFi protocol operating on the Ontology (ONT) blockchain. This protocol is entirely user-controlled, eliminating the need for third-party validation of transactions.
