Write at the beginning of your proposal "New personalized payment platform"

I don't want any pre-funded account (I need the best way to do it)

Where the buyer buys the product and pays for it.
The payment reaches the account of the merchant of the product. And the Merchant can withdraw it to any account or wallet wherever they want.
