Backpack now allows users to post Micron and SanDisk shares as margin collateral in a unified portfolio-margin account spanning stocks, crypto and other instruments. This enables stock holdings to support U.S. dollar borrowing, futures trades and spot margin positions. The platform has also launched 24/7 perpetual futures on MU, SNDK, SPY and QQQ. Investors retain full ownership of traded U.S. shares and can bridge between traditional securities and tokenized representations on Solana on a one-to-one basis. The current expansion is limited to two named equity collateral assets and four perpetual markets, with more to follow but no specific timeline provided.
