PayPal PYUSD Stablecoin Expands to Sei: Boosting Cross-Border Payments in Asia  

On September 18, 2025, PayPal expanded its PYUSD stablecoin to the Sei network and eight other blockchains via LayerZero integration, enabling faster cross-chain transactions and broader DeFi access. This PayPal PYUSD stablecoin Sei launch, in partnership with BDACS, introduces KRW1, a won-backed stablecoin for remittances and payments. PYUSD's circulating supply stands at $1.9 billion, still behind USDT's $172.3 billion in the $279.8 billion stablecoin market. The move aligns with Asia's regulatory push, positioning PYUSD for growth in a $3.5 trillion cryptocurrency ecosystem. This article covers the expansion details, features, partnerships, market impact, and implications.
