Payments & fund blocking
How money moves — and how it does not.
FastIPO implements ASBA-style fund blocking through a payment provider abstraction. Production uses SEBI-registered broker or RTA integration; local development uses a sandbox mock.

Fund blocking
Your bank
UPI block
Allotment
Amount stays in your account · never debited to FastIPO
What we never do
- UPI mandate — authorizes block, not charge
- Block amount = lots × price band high (per account)
- Release — after non-allotment or partial allotment settlement
