About DeFiner
DeFiner is a decentralized finance (DeFi) protocol that offers a configurable lending market with a lock-up function, known as the HODLer market. It features a Smart Contract Factory that allows anyone to create their own lending market on demand in a permissionless manner. Users can customize various aspects of their market, such as supported assets, maturity dates, and oracles. The protocol is built as a set of smart contracts on Ethereum and other EVM-compatible blockchains, enabling direct interaction for users and applications. Security is a priority, with the protocol having undergone multiple audits. DeFiner offers privacy through encrypted balance transfers with zero-knowledge proof traceability protection. Users can deposit crypto assets to earn interest, borrow against their deposits, create their own lending pools, and stake tokens to lock liquidity.
