Ethereum-Based Unsecured Credit Lines Outperform Traditional Collateralization Models

3Jane is a decentralized lending protocol built on Ethereum that facilitates perpetual unsecured credit lines in USDC, relying on verified financial data rather than collateral. Having raised slightly over $5 million from investors such as Paradigm, Robot Ventures, and Coinbase, the project aims to combine on-chain and off-chain data for scalable DeFi lending. By analyzing both blockchain assets and traditional credit information, including VantageScore using zkTLS technology, 3Jane evaluates borrowers' creditworthiness, enabling borrowing without over-collateralization, which is common in DeFi. The system allows users to utilize not only cryptocurrencies but also real assets and bank reserves, with fraud prevention guaranteed through Ethereum security. Currently, users can earn Credit Line points, which may lead to future rewards, by connecting wallets, pulling credit lines, and engaging in community activities. While the borrowing feature requiring Credit Karma is limited to American users, a lending option is anticipated soon, allowing users to deposit funds and increase their Credit Lines. Being in early stages, the project encourages active participation from well-established wallet holders to earn points and potentially gain special roles or benefits.
