what is CRADJ transaction in bank statement

Have u signup for any payments app?

Maybe it's s one rs verification to authenticate bank details

A google search shows it is a "CRedit ADJustment" may be the debit or credit of a verification transaction as suggested by @ANSH

Ask CS, they will fetch details of transaction and tell you.

Basically it is a penny drop verification done by financial institutions including banks, stock exchanges, insurance companies, mutual funds(sip), NPS,etc.

In case of non-fulfilment of UPI Merchant transactions, acquiring bank should raise returns/ credit adjustments within 4 calendar days from the transaction date, otherwise compensation shall be debited from acquiring bank and credit the same to issuing bank

Transaction types:

SD - sales draft

SD/R -sales draft reversal

CB - cashback

CV - credit voucher

CA - cash advance

DCC – Dynamic Currency Conversion

DBADJ – Debit - debit adjustment - CHARGEBACK

CRADJ - Credit - credit adjustment - GOOD FAITH

From Banks point of view it would be something similar 

CRADJ = PIN Debit Chargeback/UPI/Adjustment credit amount
CBADJ = PIN Debit Chargeback/UPI/Adjustment debit amount
