What is HiFi?

The HiFi Lending Protocol enables fixed-rate lending and borrowing — something much needed in decentralized finance today. Tokenizing on-chain debt allows anyone access to instant liquidity against collateral assets approved by HiFi Governance. Similar to a zero-coupon bond, the debt obligation settles on a specific future date. HiFi Governance is the community organized process of managing the various aspects of the HiFi Lending Protocol.

Why work at HiFi?

Smart contracts and ERC20/ERC721 tokens are at the heart of the crypto ecosystem. HiFi is developing a variety of smart contracts to allow our users to earn passive yield. We will also implement smart contracts that have been developed by others.
