PayPal’s PYUSD Stablecoin: Confidential Transfers and Expansion to Solana


PayPal's foray into the world of stablecoins has taken a significant leap with the introduction of its PYUSD on the Solana blockchain. This move, announced on May 29, adds a layer of innovation by offering "confidential transfers," a feature designed to enhance transaction privacy for consumers while maintaining regulatory transparency.

Confidential Transfers: A New Frontier

The deployment of PYUSD on Solana marks its expansion beyond Ethereum, its original platform. One of the standout features introduced with this transition is "confidential transfers." According to a Solana blog post, this functionality enables merchants to ensure transaction amounts remain confidential for consumers while still providing visibility to regulatory bodies.

Bitcoiner Udi Wertheimer highlighted the significance of this feature, noting its similarity to "confidential transactions" that Bitcoin developers have discussed for nearly a decade without implementation. He humorously remarked, “PayPal users will have it first? LOL.”

Why Solana?

Mert Mumtaz, CEO of Helius Labs, pointed out that PayPal’s decision to expand to Solana wasn't solely for the platform’s speed. Solana's ability to handle confidential transfers and native token programmability were key factors. This programmability includes "transfer hooks," which allow specific programs to be called with each token transfer, offering greater control over assets for wallets.

Broader Implications and Benefits

The integration of PYUSD with Solana’s token extension standard brings several advantages. This standard provides a compliance framework adhering to the SPL token standard, which simplifies development and testing processes. It also offers enterprise-ready "plug-and-play" capabilities and flexibility, enabling PYUSD to be used both within and outside the PayPal ecosystem with any compatible wallet, exchange, or library.

PYUSD's Journey and Market Presence

Launched in August 2023, PYUSD is primarily backed by U.S. Treasury Reverse Repurchase Agreements, according to its issuer Paxos. Since its inception, the circulating supply of PYUSD has increased by 50% this year, with a 24-hour trading volume of approximately $18 million, according to CoinGecko.

Originally available only on Ethereum, PYUSD has now broadened its reach with its circulation on Solana standing at $5 million, out of a total circulation of around $400 million. This expansion illustrates PayPal's commitment to enhancing the utility and adoption of its stablecoin through innovative features and strategic blockchain integrations.


PayPal’s deployment of PYUSD on Solana, coupled with the introduction of confidential transfers, marks a significant advancement in the functionality and privacy of stablecoins. This move not only enhances the appeal of PYUSD but also sets a new standard for transaction confidentiality in the digital payments space. As PayPal continues to innovate and expand its blockchain integrations, PYUSD is poised to become a more versatile and widely adopted stablecoin in the crypto ecosystem.
