Altus launched its public beta on Aug. 22, 2026, enabling eligible investors outside the United States to buy and sell more than 11,000 real U.S. stocks and ETFs with USDC transferred over Solana. Trading runs 24 hours a day, five days a week, including regular, pre-market, after-hours and overnight sessions. Users can purchase fractional shares from $1 without a stated minimum, while dividends and participation in corporate actions are included because the platform provides actual securities rather than synthetic instruments or blockchain tokens. Metaloop Inc., the Palo Alto company operating Altus and the team behind MPCVault, says it has managed more than $2 billion in assets for over 1,000 institutions during four years. Execution is handled by Atomic Vaults Securities LLC, a U.S.-registered broker-dealer and FINRA and SIPC member, with clearing by RQD* Clearing, LLC. Securities receive standard SIPC protection, but USDC balances do not. The beta is available through iOS, Android and the website, excluding U.S., EU/EEA and other restricted-jurisdiction residents. Metaloop plans to add perpetual futures, prediction markets, international equities and an Altus Visa card, without providing a timetable.
