If you see money from Earnin in your bank account, but you didn’t cash out, it most likely is a Balance Shield automatic cashout.
When you are enrolled in this feature, the app automatically sends up to $100 whenever your bank balance falls below a specific limit.
During enrollment, you also have the option to select a recurring amount in tips that will be included in the transactions. If you want to unenroll from Balance Shield, click the shield icon in the app and toggle it on or off. Learn more here.
