This guide explains how to sign the Demat Debit and Pledge Instruction (DDPI) on Zerodha, what it replaces, and the practical benefit for equity delivery sell orders.

Prerequisites

An active Zerodha demat and trading account with the equity delivery segment enabled.
Access to the Aadhaar-registered mobile number for the OTP required during e-sign.
Understanding of what the DDPI authorises: it is a standing instruction that permits Zerodha to debit (transfer out) securities from the demat account solely for the purpose of settling sell orders that the account holder has placed. The DDPI does not give Zerodha blanket authority over the demat account; the scope is limited to settlement of client-initiated sell transactions.
DDPI signing is optional. Without it, every sell order on an equity delivery holding requires the account holder to separately authorise the debit via CDSL’s TPIN (a 6-digit PIN) or the CDSL eDIS system at the time of the trade. DDPI signing eliminates this per-trade authorisation step.

Step 1: Understand the DDPI and what it replaces

Prior to the DDPI framework introduced by SEBI in 2022, brokers used a Power of Attorney (PoA) document that gave them broad authority over the client’s demat account, including pledging and off-market transfers in some cases. Concerns about PoA misuse led SEBI to introduce the DDPI as a more restricted instrument.

Overview

The Demat Debit and Pledge Instruction (DDPI) is a limited power of attorney introduced by SEBI in 2022 to replace the broader Power of Attorney (POA) that was previously used by depository participants to authorise debits from client demat accounts for exchange settlement. At Zerodha, activating the DDPI is a one-time optional process that carries a charge of Rs 75 plus 18 percent GST, totalling Rs 88.50.

The DDPI grants Zerodha, as the depository participant, specific and limited authority to debit the client’s CDSL demat account for the purpose of: (a) settling equity delivery sell transactions executed on stock exchanges, (b) settling pledge instructions for collateral margin. The DDPI cannot be used by Zerodha for any purpose beyond these specific authorities, unlike the older POA which could be broadly drafted.
