Hifi Finance is a decentralised finance (DeFi) platform focusing on fixed-rate, fixed-term lending and borrowing. Initially launched as Mainframe in 2018, it rebranded to Hifi Finance to better align with its evolving core mission. By utilizing tokenized debt, Hifi Finance allows users to lend and borrow assets over a determined period, facilitating more predictable financial planning compared to the variable-rate propositions dominant in DeFi markets. The platform's native token, HIFI, plays a pivotal role in governance, enabling holders to vote on protocol upgrades and financial parameters. Hifi Finance aims to bridge traditional finance with DeFi by introducing familiar financial products within a blockchain infrastructure.
