I've always wanted to find out which bank Cash App is associated with, and just now I realized that behind Cash App are two banks supporting it—Sutton Bank and Lincoln Savings Bank. Both are covered by FDIC insurance, so your money is protected up to $250k. I guess that's why Cash App can directly deposit your salary and issue Cash Cards. If you need to do any verification or set up automatic transfers, knowing the names and addresses of these two banks (Sutton Bank in Ohio, Lincoln in Iowa) will do the trick. By the way, have you ever wondered which bank is behind Cash App when you use it?
