Deep Dive
1. Arbitrum Integration (16 July 2025)
Overview:
PYUSD expanded to Arbitrum, a Layer-2 Ethereum scaling solution, enabling near-instant settlements at lower fees compared to Ethereum and Solana.
This integration required deploying PYUSD’s ERC-20 contract on Arbitrum, leveraging its Optimistic Rollup architecture. Users can now transfer PYUSD with a $100K weekly purchase limit and $25K weekly send cap.
What this means:
This is bullish for PYUSD because Arbitrum’s efficiency reduces transaction costs by ~90%, making PYUSD more viable for micropayments and DeFi use cases. Increased utility could drive adoption in Ethereum’s ecosystem.

2. Stellar Regulatory Approval (18 August 2025)
Overview:
Paxos secured regulatory approval from the NYDFS to issue PYUSD on Stellar, targeting cross-border remittances and SME financing.
The update involves adapting PYUSD’s codebase to Stellar’s consensus protocol, which supports 3-5 second finality and sub-cent fees.
What this means:
This is neutral for PYUSD until deployment, but approval signals readiness for global payment rails. Stellar’s network could enhance PYUSD’s role in emerging markets, pending final technical integration.

Conclusion
PYUSD’s codebase updates prioritize multi-chain scalability, balancing Ethereum’s DeFi dominance with Stellar’s remittance focus. Arbitrum’s low fees strengthen PYUSD’s payment use case, while Stellar’s approval hints at future emerging-market reach.
Will PayPal’s Layer-2 and cross-chain strategy help PYUSD close the gap with USDT and USDC?
