PayPal is rolling out the ability to buy PayPal USD, its US-dollar-backed stablecoin cryptocurrency, to “select users” today, with a full rollout coming later.

PayPal’s release says users can transfer PYUSD between Venmo and PayPal wallets for free, but warns that other compatible wallets will be subject to blockchain fees.

That ups the number of cryptocurrencies Venmo users can buy through the app from four to five.
