PayPal has expanded its dollar-pegged stablecoin PYUSD to the Arbitrum network, marking a strategic move to enhance cross-chain utility and reduce transaction costs. The update appeared in PayPal’s revised terms of service on July 16, 2025, adding Arbitrum alongside existing Ethereum and Solana support. This integration positions PYUSD to leverage Arbitrum’s high-throughput infrastructure for faster settlements and lower fees.
The expansion occurred without formal announcement, revealed through updated policy language specifying Paxos as the issuer across all three networks. Transaction limits for Arbitrum were uniquely defined, indicating tailored liquidity management for the Layer 2 environment. PYUSD’s market capitalization currently stands at approximately $844 million, having briefly surpassed $1 billion in June before receding.
This deployment follows PayPal’s pattern of blockchain diversification, having extended PYUSD to Solana in 2024 after its 2023 Ethereum debut. Arbitrum’s integration aligns with PayPal’s vision to bridge traditional finance with blockchain economies, as articulated by CEO Dan Schulman during PYUSD’s initial launch.

PayPal’s Stablecoin Evolution
PYUSD represents PayPal’s flagship entry into the stablecoin market, designed as a 1:1 dollar-backed digital asset collateralized by U.S. dollar deposits and short-term treasuries. The stablecoin launched exclusively on Ethereum in August 2023 before expanding to Solana in May 2024. Its expansion to Arbitrum completes a multi-network strategy targeting diverse blockchain ecosystems.
The token facilitates payments and transfers within PayPal’s ecosystem while enabling external blockchain interoperability. Recent network expansions included Berachain, Flow, and Plumme mainnet earlier in 2025, though PYUSD adoption growth remains gradual despite increased accessibility.
Arbitrum’s Technical Advantages
Arbitrum operates as an Ethereum Layer 2 solution, utilizing optimistic rollups to batch transactions off-chain before finalizing them on Ethereum’s mainnet. This architecture delivers near-instant settlement times while reducing gas fees by up to 90% compared to Ethereum Layer 1. The network has emerged as a preferred environment for decentralized finance (DeFi) applications due to its cost efficiency.
Arbitrum’s integration comes two weeks after Robinhood confirmed compatibility with the network, suggesting coordinated efforts to link traditional finance platforms with decentralized liquidity pools. The network’s total value locked (TVL) consistently ranks among Layer 2 leaders, providing PYUSD with established infrastructure for potential DeFi integrations.
Market Impact and Adoption Challenges
PYUSD’s expansion occurs amid intensifying stablecoin competition, with PayPal aiming to capture market share from dominant players like USDT and USDC. Despite multi-chain availability, PYUSD’s market cap remains modest compared to industry leaders, reflecting adoption hurdles in both retail and institutional segments.
The Arbitrum deployment could accelerate usage through:
- Lower transaction costs for micropayments
- Enhanced compatibility with DeFi protocols
- Faster settlement for merchant transactions
Analysts note that PYUSD’s growth trajectory faces challenges from established stablecoins and fluctuating market conditions. Its performance may hinge on PayPal’s ability to integrate the token deeper into its payment infrastructure and partner ecosystems.

The PYUSD expansion signals growing corporate blockchain adoption, potentially influencing other fintech firms to explore multi-chain stablecoin strategies. Arbitrum’s integration may accelerate PYUSD’s utility in emerging DeFi applications while testing market appetite for corporate-issued stablecoins beyond Ethereum’s ecosystem.
- Stablecoin
- A cryptocurrency pegged to a stable asset like the U.S. dollar, designed to minimize price volatility. Stablecoins maintain reserves as collateral to support their value.
- Layer 2
- A secondary framework built atop a blockchain (like Ethereum) to improve scalability and reduce fees. Layer 2 solutions process transactions off-chain before recording them on the main blockchain.
- Arbitrum
- An Ethereum Layer 2 scaling solution using optimistic rollups to enable faster transactions and lower costs while inheriting Ethereum’s security. It’s among the most adopted Layer 2 networks for DeFi applications.
