MF purchase bank account

Hello,

Since the amount has to be deducted from the bank. Is it mandatory to still use the same account link with Zerodha?

For eg. If my linked bank is UCO can I buy MF on Coin with ICICI bank account?

If it has to be a linked account, can it be any account linked to my trading account? Say I have UCO as primary and PNB as secondary. Can I use PNB to buy MF on coin?

Also, when I redeem my fund, which account will the money be deposited to?

Thanks for your help.
Regards.

The payment for mutual fund investments has to be made from the primary bank account linked to your trading account. You can check the process here.

Redemption proceeds too will be credited to the primary bank account.

thank you
