CDSL Easiest is not offered by any online stock broker. This is because the broker loses the POA over your Demat Account when you sign up for CDSL Easyst. 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.
