Implement Escrow-style Payment System #58
Description
Add support for an escrow-style payment flow where the platform holds the buyer’s payment temporarily, and releases it to the seller after confirmation.
This system will use a third-party payment gateway like Razorpay Route or Cashfree Payouts to:
- Accept buyer payments (UPI / cards / netbanking)
- Temporarily hold funds
- Automatically disburse to seller after approval or set conditions
This improves trust and reduces scams on OpenEx by ensuring the seller only receives funds once the item is confirmed to be exchanged.
