The DDPI (Demat Debit and Pledge Instruction) is an authorization document that permits your stockbroker, such as Zerodha to automatically debit shares from your demat account when you sell them and transfer them to the exchange. By submitting this document, you eliminate the need to manually enter the CDSL T-PIN and OTP each time you sell shares. However, it’s important to note that using DDPI is completely optional, and if preferred, you can continue to authenticate each sale by entering the T-PIN for every transaction.
