Is there CDSL Easiest facility available in Zerodha?

No. This is because when you sign up for CDSL Easyest, the broker loses your POA (Power of Attorney). The broker cannot debit Demat shares and you can't sell shares using your trading platform.

For share transfers to other Demat accounts, they recommend that you use DIS (delivery instructions slips).

CDSL Easiest allows you to submit inter-depository, early pay-in, and off-market debit instructions directly from your DEMAT account via the CDSL online portal.
