what's f(x) protocol?
f(x) Protocol is a decentralized finance (DeFi) protocol built on Ethereum that provides leveraged long and short positions on ETH and BTC with up to 7x exposure, featuring zero-stress leverage through progressive liquidation mechanisms to minimize risks. It introduces fxUSD, a decentralized stablecoin that generates sustainable yields from protocol fees and stability pools, offering users organic returns without traditional funding rates. The protocol emphasizes full decentralization, with no oracles, market makers, or human intervention, and has undergone multiple audits by firms like OpenZeppelin and Trail of Bits. Users can trade seamlessly while maintaining control of their assets, and the governance token FXN enables participation in protocol decisions and yield boosts. f(x) Protocol aims to reinvent DeFi by combining stablecoin utility with leveraged trading in a transparent, on-chain manner.
f(x) protocol shares its team with Aladdin DAO.
