USD cash is maintained within your US brokerage account by DriveWealth our US broker-dealer partner. Your funds and securities are protected by SIPC (link to FAQ).
All transfers into your account, trade settlements, dividends and other corporate action-related distributions are kept in your USD wallet until you make an investment, transfer or withdraw your funds.
Our broker partner purchases DARXX, a money market fund administered by Bank of New York Mellon. The holdings in this fund are rebalanced as your cash balance moves up and down, which you'll see displayed on your Monthly Account Statement.
