PayPal’s stablecoin push is now being tied to Polygon’s Open Money Stack, giving businesses another route to use PYUSD in payment flows instead of treating it only as an exchange asset.

PayPal already positions PYUSD as a dollar-backed token for global transfers and merchant use, while Polygon’s stack is built around wallets, fiat access, orchestration and on-chain settlement in one integration.

This matters because stablecoin adoption is moving from “which chain lists the token” to “which stack can make it usable for businesses.” The second-order risk is concentration: if payment apps depend on a bundled stack, failures in compliance, routing or off-ramps can affect the whole flow, not just the blockchain leg.

Next, watch actual PYUSD volume on Polygon and whether merchants use it for settlement rather than treasury experiments.
