Peer-to-Peer Lending / Borrowing Platform
Why Choose This Project?
Traditional lending platforms are controlled by banks or financial institutions with high-interest rates, slow approval, and limited access. A blockchain-powered P2P Lending Platform eliminates intermediaries, enabling secure, fast, and transparent loans between users using smart contracts.
This DeFi platform lets users lend or borrow digital assets directly, with collateral, interest rates, and loan terms encoded in smart contracts — ensuring trustless execution and full transparency.
