To start trading, you must fund your account by transferring cash from a Connected SoFi Account (SoFi Checking and Savings). We then convert this cash into a stablecoin (such as USDC) to execute the trade. Please be aware that stablecoins are not issued or guaranteed by SoFi Bank or the FDIC and may lose value. Due to this structure, funding and withdrawals are restricted to your Connected SoFi Account.
