Credio is an oracle network that helps DeFi protocols, issuers and investors on Arbitrum to manage risks regarding RWAs in an automated, decentralized and privacy-preserving manner. We focus on providing machine learning inference feeds for illiquid RWAs from a decentralized community of data scientists, risk managers and rating agencies. By blending AI with blockchain, Credio brings a new predictive layer to smart contracts, making creditworthiness programmable, enabling the massive growth potential of the tokenized RWA on Arbitrum.
