"To complete a payment, buyers connect their existing bitcoin wallets to the PayPal checkout.
The digital assets are then exchanged on platforms such as Coinbase or Uniswap, converted to PayPal’s stablecoin (PYUSD), and finally settled in U.S. dollars for the merchant."
Doesn't sound like bitcoin payments to me...sounds like hooking up one's Coinbase account to another's PayPal account. When paying bitcoin at a PoS, "connecting my wallet" has never been a step.
