Stable announced that PayPal’s USD stablecoin, PYUSD, went live on the Stable mainnet on December 18. PYUSD, issued by Paxos and pegged to the U.S. dollar, was previously introduced as a payout option for U.S.-based YouTube creators in Q3 2025, marking one of the most prominent consumer-facing applications of the stablecoin. The mainnet launch extends PYUSD’s reach beyond existing payment integrations, reinforcing its role in fast, low-volatility digital settlements.
