11% APY on Stablecoins? Unraveling the Mystery of PayPal’s PYUSD Success on Solana

In the ever-evolving landscape of digital finance, a new player has emerged, capturing the attention of crypto enthusiasts and traditional finance alike. PayPal, a stalwart in the online payment industry, has made a significant leap into the world of cryptocurrencies with its stablecoin, PYUSD. What’s particularly intriguing is not just the stablecoin’s rapid growth, but its unexpected flourishing on the Solana blockchain, offering eye-catching returns that have left many in the industry both excited and puzzled.
The Meteoric Rise of PYUSD
On August 27, 2023, official data revealed that the market capitalization of PayPal’s stablecoin, PYUSD, had surpassed the $1 billion mark. This milestone is particularly impressive considering that the supply has more than doubled since June of the same year. But what’s driving this explosive growth?
According to Visa’s stablecoin dashboard, PYUSD’s user activity has seen a dramatic increase. Monthly active wallet addresses jumped to over 25,000 in July, a significant leap from the 9,400 recorded in May. This surge in activity coincides with PYUSD’s expansion to the Solana network in May, a move that has proven to be a game-changer for the stablecoin.
In just three months following its Solana debut, PYUSD grew from zero to $650 million, surpassing its supply on the Ethereum chain. Data from DefiLlama shows that the supply of PYUSD on the Solana chain has increased by a staggering 171% in the past month alone. These figures paint a picture of rapid adoption and growing trust in PayPal’s digital currency offering.

PayPal’s Strategic Move to Solana
The decision to expand PYUSD to the Solana network was not made lightly. PayPal, with its two-decade-long commitment to providing fast, low-cost, and global payment services, saw in blockchain technology the next frontier of digital payments. The company recognized that on-chain payments offer several advantages over traditional systems, including faster settlement, lower costs, and programmability.
While PYUSD was initially launched on Ethereum in August 2023, PayPal quickly realized that to provide practical value to consumers and merchants, a more efficient blockchain was necessary. This is where Solana came into the picture.
Solana’s appeal lies in its technical capabilities:
- Nearly instant settlement and finality
- Median transaction fee of less than one cent
- A thriving ecosystem with over 2,500 developers
But perhaps most crucially, Solana’s unique token scaling capabilities became a key factor in PayPal’s decision. PYUSD utilizes multiple token extensions on Solana, including confidential transfers, transfer pegs, and memo fields. As PayPal stated, “These features are not optional. If you want PYUSD to play a role in the wider commercial field, you must provide it to merchants.”
The results of this strategic move speak for themselves. Currently, Solana has become the main platform for PYUSD, commanding a market share of 64%, compared to Ethereum’s 36%.

The Kamino Finance Phenomenon
While the growth of PYUSD on Solana is impressive in itself, what’s truly catching the eye of the crypto community is the high returns being offered on Kamino Finance, a decentralized finance (DeFi) protocol on the Solana blockchain.
As of August 27, more than 49% of the circulating PYUSD supply was deployed to Kamino, totaling a staggering $496 million. But what makes Kamino Finance so attractive, and why has it become the preferred staking protocol for PYUSD?
Founded in 2022, Kamino Finance is a DeFi protocol that integrates lending, liquidity provision, and leverage. Users can use centralized liquidity positions as collateral and build automated liquidity strategies with one-click operations and automatic compounding. The project, incubated by Hubble Protocol, has quickly risen to prominence in the Solana ecosystem.
According to thedefiant, Kamino has become Solana’s largest lending platform, with a Total Value Locked (TVL) of over $1.6 billion. What’s truly remarkable is the return offered on PYUSD deposits. On Kamino, 496 million PYUSD enjoy an annualized return of 11.73%. To put this into perspective, depositors receive an additional reward of over 1.2 million PYUSD per week.
The Mystery of High Returns
The high returns offered on Kamino Finance have raised eyebrows and questions in equal measure. How can a stablecoin offer such high annualized returns, and is this sustainable in the long term?
Some in the crypto community have speculated about the source of these rewards. KOL @0xBalloonLover questioned, “You will never know how much rewards the Solana Foundation has paid to encourage people to mint PYUSD.” However, this speculation was quickly countered by prominent figures in the Solana ecosystem. Kyle Samani, managing partner of Multicoin Capital, and Mert, a core member of the Solana community and founder of Helius, both stated that the Solana Foundation did not actually pay anything towards these rewards.
This denial from key Solana figures leads to an intriguing possibility: could PayPal itself be behind these high rewards? After all, as the issuer of PYUSD, PayPal stands to benefit significantly from increased adoption and circulation of its stablecoin.
The Sustainability Question
While the high returns are undoubtedly attractive, questions about sustainability linger. On August 20, well-known Web3 analyst Alpha Pls estimated that Kamino’s annualized revenue was $17.4 million. This figure suggests that maintaining the current level of rewards might be challenging in the long term.
Moreover, unlike previous DeFi mining incentives that often used project-specific tokens, these PYUSD rewards are real dollar-backed stablecoins. This makes the source and sustainability of these rewards even more intriguing.

The Bigger Picture: PayFi and the Future of Finance
The rapid growth of PYUSD and its integration with Solana point to a broader trend in the crypto space. Web2 giants are increasingly targeting the crypto market, recognizing its potential to revolutionize finance.
Lily, president of the Solana Foundation, highlighted at the Asian Blockchain Summit that PayFi (the integration of traditional payment systems with decentralized finance) will be the biggest theme in this round of the crypto cycle. She also emphasized that Solana is the best fertile ground for the actual implementation and widespread application of this concept.
This convergence of traditional finance giants like PayPal with cutting-edge blockchain technology like Solana represents a significant shift in the financial landscape. It’s a move that could potentially bridge the gap between traditional and decentralized finance, making crypto more accessible to mainstream users.
Conclusion: A New Era of Digital Finance?
The story of PYUSD’s growth on Solana and the high returns offered on Kamino Finance is more than just a tale of impressive numbers. It’s a glimpse into the future of finance, where traditional payment giants leverage blockchain technology to create more efficient, accessible, and potentially lucrative financial products.
However, as with any rapidly evolving technology, questions and challenges remain. The sustainability of high returns, the long-term adoption of stablecoins like PYUSD, and the regulatory landscape surrounding these innovations are all factors that will shape the future of this space.
What’s clear is that we’re witnessing a significant moment in the evolution of digital finance. As PayPal pushes the boundaries with PYUSD and platforms like Solana and Kamino Finance provide the infrastructure for innovation, we may be on the cusp of a new era where the lines between traditional and decentralized finance blur, creating new opportunities and challenges for users, developers, and regulators alike.
The crypto community will be watching closely as this story unfolds, eager to see how PYUSD’s journey on Solana continues and what implications it holds for the broader adoption of cryptocurrencies and blockchain technology in mainstream finance.
