3Jane is a decentralized lending protocol on Ethereum that provides unsecured USDC loans based on users' creditworthiness rather than traditional collateral. The platform assesses creditworthiness through the 3CA algorithm, which analyzes on-chain activity, off-chain financial data, and credit scores. Lenders can deposit USDC to mint USD3, earning yield from the pooled credit lines, while borrowers can access credit lines by linking their wallets and financial accounts.
