The challenge

Yield farming lacks privacy. Every position, balance, and strategy is visible on-chain — exposed to MEV bots, copy-traders, and on-chain analytics. Unlike traditional finance, there is no private yield optimization onchain. The net effect: large yield farmers become targets for MEV extraction, while privacy-conscious users have no confidential yield options. Existing solutions ( Tornado Cash, Railgun) are for transfers — not yield generation. They provide privacy but sacrifice yield.

The approach

iEx AI is a confidential yield vault aggregator where: Key insight: Yield and privacy are not opposites if you draw the boundary at the depositor level: the world sees the vault succeed, but no one sees the individual depositors who made it succeed.
