Fintech services like PayPal, and Cash App have a "instant" method already which pushes funds through a payment as a debit card transaction (like a refund from a merchant would, but instant).
Instant Deposits are subject to a 0.5% -1.75% fee (with a minimum fee of $0.25) and arrive instantly to your debit card.
