[Lighter: Introducing cross-margin mechanism in gold and silver markets starting today, expanding to other RWA markets next week] Lighter announced on platform X that the platform is introducing a cross-margin mechanism for real-world assets (RWA), starting today with the gold and silver markets. Next week, this mechanism will be expanded to all other RWA asset markets. This means that RWA assets can share collateral with crypto-native markets, thereby improving capital efficiency.
