The problem

A single farmer runs 10,000 wallets, drains yield-farming incentives, distorts governance, and exits before honest users see returns. Traditional KYC pushes users away — and can still be faked.

HelixKey solution

Every wallet biometrically anchored. One human = one wallet. Sybil-detection at the protocol level, without collecting a shred of PII. Verified users get premium terms (higher yields, lower borrow rates) as an incentive.
