I've been looking for a solution for transferring money from one bank account to another at scale for an upcoming product as introducing payment gateway in this is not commercially viable for a side project.
I hope the API pricing & compliance is accommodating to side project i.e. shouldn't expect company incorporation for the API; e.g. Stripe India requires company incorporation for international payments ¯\_(ツ)_/¯ even though Paypal doesn't require one (I understand that Decentro is not a PG).
There's an extraordinarily large need gap in the ecosystem for enabling commercial viability of side projects in India. Can't validate ideas for commercial acceptance, if one has to undergo numerous compliances to get access to basic financial instruments.
