Payments firm PayPal's (PYPL) U.S. dollar stablecoin is being introduced to nine more blockchains by interoperability protocol LayerZero (ZRO), expanding the token beyond the four blockchains — Ethereum, Solana, Arbitrum and Stellar — where it's natively issued.LayerZero integrated PayPal USD (PYUSD), issued by fintech firm Paxos, into its Hydra Stargate system, creating a permissionless version of the token dubbed PYUSD0 that's one-to-one interchangeable with the underlying stablecoin.The move makes the token available on Abstract, Aptos, Avalanche, Ink, Sei, Stable, and Tron, while existing community-issued versions on Berachain and Flow will convert automatically.PayPal launched its PYUSD in 2023 as one of the first major payments firm-backed stablecoins.
