Axis bank works as a PSP (Payment Service Provider) Bank for Jupiter UPI transactions. Here Jupiter is a Third Party Application Provider (TPAP).
I had the same doubt regarding axis bank as @Pratyay_Mustafi 
Thanks for the clarification @saurabh.s and @yagnesh01 bros. 
Initially, I believed that Jupiter merely had some kind of partnership with Federal Bank, never realizing that we are all actual Federal Bank account holders. However, I have come across comments from fellow members here stating that “Federal Bank doesn’t even consider Jupiter as a bank.” Therefore, it seems that if Federal Bank truly considers us part of their “family,” issues such as changing mobile numbers (in the event of losing the primary SIM) and utilizing CDMs for cash deposits etc. can be resolved quickly and effortlessly. 
Actually Federal Bank consider Jupiter as a separate bank.
Connect with the customer support they might help you.
Use any other federal bank debit card or fi debit card to get access to net banking then use Jupiter account as default for net banking transaction
Jupiter customer support. As per the trello features tracker, NetBanking feature has been marked as shipped
Is the address change feature available in Federal Net Banking?
@Krishnendu_Chowdhury I don’t think so. I can see only options such as Land phone, office phone, Income, Marital status, education etc. under the “Update Profile Details”
