Sub-Account Segregation

Sub-account segregation is a structural design where a single user account is divided into multiple sub-accounts with independent margin requirements. This allows traders to isolate the risk of different strategies or asset classes, preventing a loss in one from affecting the collateral in another.

It effectively brings the benefits of isolated margin to a platform that might otherwise default to cross-margin. This is highly beneficial for professional traders who manage diverse portfolios and want to avoid cross-contamination of risks.

It also enhances the protocol's security, as it limits the blast radius of any single account failure. Implementing this requires complex accounting within the smart contract layer to track individual balances accurately.
