Zero-Knowledge Margin Validation

Zero-Knowledge margin validation is a mechanism where a trader proves they possess sufficient collateral to cover a leveraged position without revealing their total wallet balance or other holdings. In decentralized derivatives, this is crucial for maintaining solvency while protecting the privacy of the trader's broader portfolio.

The system checks the proof against the required margin ratio and approves the trade if the condition is met. This prevents the protocol from needing to know the user's entire net worth, which reduces the surface area for targeted attacks.

It allows for cross-margin trading where collateral can be aggregated across different assets without exposing the specific composition of the collateral pool. This enhances the security of the margin engine by decoupling verification from data exposure.

It is a foundational element for privacy-first decentralized margin trading.
