PayPal USD (PYUSD) Cryptocurrency: Comprehensive Overview
Core Definition and Technology
PayPal USD (PYUSD) is a stablecoin that is redeemable 1:1 for US dollars. PYUSD is a type of cryptocurrency called a stablecoin and is fully backed by US dollar deposits, US treasuries, and similar cash equivalents. PayPal USD is issued by Paxos Trust Company, LLC (Paxos).
Blockchain Architecture
PayPal USD is issued by Paxos on the Ethereum, Solana and Arbitrum blockchains. PYUSD was launched as a standard ERC-20 token on the Ethereum blockchain. Through LayerZero's integration announced September 18, 2025, PYUSD expanded to nine additional blockchains: Abstract, Aptos, Avalanche, Ink, Sei, Stable, Tron, plus upgraded versions on Berachain and Flow.
The ERC-20 standard provides several benefits that make it an attractive option for stablecoins. One of the key benefits of the ERC-20 standard is its interoperability with various platforms and exchanges. This feature simplifies the process of incorporating PYUSD into smart contracts and facilitates easy acceptance of PYUSD payments.
Primary Use Cases and Real-World Applications
PYUSD paves the way for payment innovation facilitating fast, cross-border money movement to friends & family, international payments, direct flows to developers and creators, and fostering continued expansion into digital assets.
You can send it to other people on PayPal and Venmo without fees. PYUSD supports peer-to-peer payments, allowing for fast, fee-free transfers between PayPal users in the U.S. It can be used for everyday purchases at merchants that accept PayPal, and it facilitates seamless conversion between cryptocurrencies within the PayPal ecosystem.
PYUSD on Stellar can be used for fast (~5 seconds), affordable ($0.001) cross-border payments, giving expanded access to essential financial services to underserved locations across the globe.
PYUSD is also integrated with PayPal's other services, such as Venmo, PayPal's peer-to-peer payment app, and PayPal's business payment solutions.
Founding Team, Key Developers, and Project History
PayPal USD was launched on August 7, 2023, as part of PayPal's initiative to expand its role in the digital currency space. PayPal (NASDAQ: PYPL) announced the launch of a U.S. dollar-denominated stablecoin, PayPal USD (PYUSD).
PayPal USD, a stablecoin initiative, is not directly linked to the founders of PayPal. Instead, it represents a collaborative effort between PayPal and Paxos to introduce a digital currency that maintains a stable value over time.
PYUSD's integration in the PayPal and Venmo apps introduced it to over 100 million US users.
Tokenomics: Supply, Distribution, and Mechanics
Supply Structure
The tokenomics of PayPal USD (PYUSD) is structured around a centralized supply mechanism, where the total supply is controlled and issued by PayPal to ensure stability and regulatory compliance. Unlike decentralized cryptocurrencies, PYUSD does not have a mining process; instead, new tokens are issued based on demand.
PYUSD's value is directly tied to the US Dollar, which means that the supply of PYUSD tokens is adjusted based on demand. If more people wish to purchase PYUSD, the issuer will create new tokens and back them with an equivalent amount of US Dollars. Conversely, if people redeem their PYUSD for USD, the tokens will be removed from circulation.
Current Circulating Supply
The current CoinMarketCap ranking is #27, with a live market cap of $3,590,492,901 USD. It has a circulating supply of 3,592,666,416 PYUSD coins.
Inflation/Deflation Mechanics
When users deposit U.S. dollars with Paxos, new PYUSD tokens are minted on the blockchain. These tokens can be transferred on supported networks and redeemed 1:1 for USD at any time. Supply Control (2025) – Rate-limited minting/burning via dedicated contract.
Consensus Mechanism and Network Security Model
Consensus Approach
Unlike traditional cryptocurrencies, PayPal USD operates under a centralized model, with PayPal and Paxos Trust Company overseeing its issuance and management. This centralized approach ensures regulatory compliance and maintains the stability of the token's value.
Reserve Backing and Security
Paxos' issuance of the stablecoin PYUSD – and its reserves – are subject to strict regulatory oversight by the Office of the Comptroller of the Currency (OCC). Reserves are held 100% in US dollar deposits, US treasuries and cash equivalents – meaning that customer funds are available for 1:1 redemption with Paxos.
Paxos publishes monthly reserve reports and attestations, independently verified by WithumSmith+Brown, PC, an accounting firm. These reports adhere to the attestation standards of the American Institute of Certified Public Accountants (AICPA), providing an additional layer of trust and assurance to users regarding the stablecoin's backing and stability.
In the event of Paxos' insolvency, customer assets would not be used to satisfy the debts of Paxos because client assets are held in segregated, bankruptcy remote accounts.
Key Partnerships and Ecosystem Integrations
Major Partnerships
PayPal and Mastercard are working together to drive future network settlement capabilities with PYUSD.
Coinbase and PayPal will not only enable simplified customer access to stablecoins, but also make it easier than ever for millions of PayPal customers to bring their finances onchain. Coinbase aims to leverage its leading infrastructure platform to expand support for stablecoins to PayPal's largest merchant partners, promoting broader adoption of faster and more efficient financial services. Coinbase will also collaborate with PayPal to explore new use cases onchain utilizing PYUSD.
PayPal announced plans to make the PayPal USD (PYUSD) stablecoin available on the Stellar network pending regulatory approval by the New York State Department of Financial Services (NYDFS).
DeFi Integration
PYUSD has maintained active integration with major DeFi protocols including Aave and Curve for lending, borrowing, and yield generation. The most notable growth driver was strategic partnerships with Solana-based lending platforms like Kamino.
Platform Integration
PayPal USD is also available on Venmo! This means that PYUSD is available for purchase and sale on Venmo and can be sent to compatible external wallets and friends and family on Venmo and PayPal, and vice versa.
Competitive Advantages and Unique Value Proposition
Brand Trust and Distribution
PYUSD is significant because it is the first stablecoin issued by a major global payments company. This gives it immediate mainstream visibility and direct integration within PayPal's massive ecosystem.
The strategic purpose is leveraging PayPal and Venmo ecosystem integration to drive adoption from mainstream users, acting as a frictionless on-ramp for 400 million users to convert fiat into on-chain PYUSD.
Regulatory Compliance
Unlike other stablecoins, such as USDT and USDC, PYUSD is subject to regulatory oversight by the New York Department of Financial Services (NYDFS).
Reserve Quality
Unlike many other stablecoins, PYUSD is backed by USD deposits and other cash equivalents, which offer more stability and reliable off-ramps than other common backing methods for stablecoins like commercial paper or commodities.
Multi-Chain Accessibility
PYUSD's September 2025 developments signal an aggressive expansion strategy focused on mainstream payments and multi-chain accessibility. The combination of peer-to-peer crypto functionality, presence across 13 blockchains, and strategic partnerships creates multiple pathways for adoption while maintaining regulatory compliance.
Current Development Activity and Roadmap Highlights
Recent Expansions
PYUSD's expansion to Arbitrum represents a milestone in the stablecoin's evolution, bringing Layer 2 efficiency to payment applications for the first time and providing: Near Instant Settlement at Scale: Transactions on Arbitrum process in seconds, enabling near real-time payment experiences that maintain the transparency and programmability of blockchain technology. Micropayment Viability: With transaction costs typically under one cent, PYUSD unlocks potential use cases including content micropayments, usage-based billing, and instant rewards distribution that would be economically unfeasible on other networks.
2025-2026 Roadmap
PYUSD's 2026 roadmap prioritizes institutional DeFi integration and retail accessibility, aiming to transform it from a payment stablecoin to a yield-bearing asset. PYUSD's roadmap focuses on expanding utility and integration across ecosystems. USDAI Incentive Launch (January 2026) – $1B program offering 4.5% yield on PYUSD deposits for AI infrastructure loans. Spark Institutional Lending (2026) – Fixed-rate loans for large borrowers using PYUSD as collateral. Spark Mobile App (2026) – Retail access to Spark's yield and lending services with PYUSD.
Technical Enhancements
PYUSD integrated EIP-3009 and EIP-2612 standards, letting users approve transfers via signatures instead of on-chain gas payments. This allows delegated spending (e.g., recurring subscriptions) and batch transfers, reducing Ethereum gas costs by ~30% for frequent users.
Merchant Adoption
PayPal is simplifying cross-border commerce for merchants by connecting an unmatched combination of cryptocurrencies, digital wallets, and merchants worldwide, while simultaneously reducing transaction fees by up to 90%. With a transaction rate of 0.99%, Pay with Crypto decreases the cost of transactions by up to 90% when compared to international credit card processing.
