Building with PayPal USD (PYUSD) on Solana
Solana’s speed and scalability make PYUSD transactions seamless, cost-efficient, and nearly instantaneous—unlocking a wealth of opportunities for developers and users alike.
With PayPal USD now available on Solana, developers gain access to a new, versatile stablecoin for their projects. Thanks to an accessible Solana Devnet faucet for test tokens, comprehensive documentation, and deep integration into the Solana ecosystem, utilizing PYUSD is easier than ever.
This guide explores what PYUSD is, how to build with it on Solana, and how developers can harness its potential for innovative projects.
What Is PYUSD?
PayPal USD (PYUSD) is a stablecoin issued and managed by Paxos Trust Company on behalf of PayPal. Designed to maintain a 1:1 peg with the U.S. dollar, PYUSD provides a reliable, secure, and blockchain-powered alternative to traditional fiat currency.

Initially launched on Ethereum, PYUSD was extended to Solana on May 29, 2024, capitalizing on Solana’s high-performance network. Known for its fast block times (approximately 400 milliseconds), scalable infrastructure, and low transaction costs, Solana is an ideal environment for a digital asset like PYUSD.
The stablecoin’s multichain functionality ensures flexibility, allowing users to select the blockchain that best suits their needs. Its adoption on Solana further enhances its global accessibility, offering low-cost, near-instant transfers for users worldwide.
