Policy Tailwinds, Giants All In: The "Institutional Game" Behind Solana's Stablecoin Supply Hitting New Highs

Author: Jae, PANews

On March 19, the stablecoin supply on the Solana blockchain officially surpassed the historic threshold of $17 billion.
This figure not only set a new high for the Solana network but also reflects its ecosystem’s resilient expansion amid a bear market, moving toward the goal of “Internet Capital Markets.”
Behind the $17 billion, it is no longer driven solely by meme coin speculation but results from policy benefits, Wall Street institutional integration, and ecosystem synergy effects.
From Stripe to PayPal, from Visa to BlackRock, giants from Wall Street and Silicon Valley are influencing Solana’s development with real capital.
From $1.5 billion to $17 billion, a steep recovery curve

The growth trajectory of Solana’s stablecoin supply is a steep curve spanning four years from bottom to peak.
In November 2022, affected by the FTX collapse, the total stablecoin amount on Solana shrank to $2 billion, lingering near the $1.5 billion bottom for nearly half a year.
At that time, skepticism about Solana peaked—has the “Ethereum killer” become history?
However, the subsequent recovery slope surprised everyone.

Phase 1: Endogenous Recovery Period (Q1-Q4 2024)
The stablecoin supply on Solana steadily recovered from $2.2 billion at the start of the year to around $5.3 billion.
During this period, DEX protocols like Jupiter and Raydium drove Solana’s wealth effect, attracting retail investors back with low interaction costs.
Stablecoins, as the “rigid demand fuel” for on-chain transactions, began to re-accumulate.

Phase 2: Meme and Liquidity Resonance Period (Q1-Q2 2025)
In early 2025, political meme coins like TRUMP triggered a rapid influx of global liquidity into Solana.
Stablecoin supply surged from $5.3 billion to $12.8 billion within four months, an increase of over 2.4 times.
DEXs like Meteora locked significant liquidity through USDC trading pairs, elevating stablecoins from mere asset anchors to “liquidity amplifiers” for on-chain trading.

Phase 3: Regulatory and Institutional Bonus Period (Q3 2025 to present)
In July 2025, the signing of the GENIUS Act provided legal protection for the large-scale circulation of compliant assets like USDC and PYUSD.
The breakthrough of $17 billion essentially reflects traditional financial capital beginning to allocate assets directly through Solana’s high-performance infrastructure.
Notably, non-USDC/USDT stablecoins grew about 15 times in the past 12 months, accounting for over 20% of total supply.
This “dual super and multiple” pattern reduces Solana’s dependence on a single issuer, enhancing overall ecosystem resilience.

However, risks remain. On March 18, PPI inflation data exceeded expectations, delaying the Federal Reserve’s rate cut expectation to September.
Macroeconomic liquidity is tightening. If this trend continues, the turnover rate of stablecoins relying on high-frequency trading on Solana could plummet sharply.

Policy benefits and deep integration with giants
In July 2025, the enactment of the “Genius Act” set clear “game rules” for payment stablecoins.
For Solana, although the ban on interest policies in the Act limited some yield-bearing stablecoins’ expansion, it also boosted confidence among compliant capital like Circle and PayPal.
The milestone of $17 billion in stablecoin supply is closely tied to the deep integration with payment giants since last year.
In October 2025, Stripe added Solana support for its crypto products. This allows automatic conversion of stablecoins to fiat, with funds settled directly in USD to merchants’ Stripe accounts, eliminating price volatility risks.
In December 2025, Visa announced that US banks could use USDC for transaction clearing via Solana—marking its first comprehensive deployment of stablecoin settlement services within the US banking system.
By March 2026, Western Union partnered with infrastructure provider Crossmint to support the issuance of USDPT stablecoin on Solana, connecting to global payment networks.
Currently, PYUSD’s market cap on Solana has reached about $77.7 million, a 600% annual increase.
This growth is mainly driven by the launch of “Pay with Crypto,” enabling millions of merchants to accept over 100 cryptocurrencies and instantly convert transactions at a 0.99% fee into PYUSD.
With PYUSD, Solana’s infrastructure has expanded to users in 70 countries and regions worldwide.

The continuous adoption by payment giants turns the $17 billion figure from speculative capital into a real reflection of payment channel transfer.
More importantly, the law clarifies the priority of stablecoin holders’ claims in case of issuer bankruptcy, providing consumer protections comparable to traditional finance.

DeFi, RWA, and AI Agent Payments: A Trifecta of Ecosystem Synergy
The surge in stablecoin scale and the explosion of application layers within the Solana ecosystem form a strong positive feedback loop.
A large portion of the $17 billion stablecoins are locked in various DeFi protocols.
Kamino, the largest lending platform on Solana, has a total value locked (TVL) of $2.9 billion, with active loans reaching $1.2 billion.
Kamino’s interest-bearing liquidity tokens, kTokens, allow users to earn fees while using these tokens as collateral to re-borrow stablecoins, greatly improving capital efficiency.

Jupiter, as Solana’s traffic gateway, processes over 70% of on-chain transactions.
Its aggregator partnered with BlackRock to launch JupUSD, which invests stablecoin reserves into tokenized government bonds, providing robust underlying liquidity with a circulation close to $74 million.
By March 2026, the market value of real-world assets (RWA) on Solana exceeded $1.8 billion, over ten times the amount a year earlier.
Ondo deployed tokenized short-term US bonds and money market funds on Solana, allowing users to bypass traditional brokers for 24/7 trading.
BlackRock’s BUIDL fund on Solana exceeds $500 million, indicating top-tier asset management firms are beginning to see Solana as a primary platform for tokenization transformation.

Another prominent trend is the explosive growth of AI Agents’ economic output on Solana.
Thanks to Solana’s microsecond confirmation times and extremely low costs, AI Agents can perform high-frequency micro-payments, such as thousands of API calls settled per second.
Compared to traditional banks or slower L1 networks, supporting such high-frequency small-value capital cycles is challenging.
Stablecoins are the ideal payment medium for these “digital labor forces.”

However, shadows lurk beneath the sunshine. Under the surface of liquidity expansion, potential risks and challenges within the Solana ecosystem cannot be ignored.
As liquidity increases, activities of MEV attackers become more rampant.
While mechanisms like Jito return some profits to holders, high-priority fees during peak times may erode Solana’s low-cost advantage, hindering the widespread adoption of micro-payments.
Nevertheless, the $17 billion stablecoin supply on-chain is just one node in Solana’s network.

From Stripe to Visa, and from PayPal to BlackRock, the collective adoption by giants is helping build a financial empire beyond the crypto sphere.
How to maintain high performance and low costs while effectively responding to macroeconomic headwinds and internal network challenges will be key to Solana’s continued leadership in defining the “Internet Capital Markets.”
