Solana stablecoin holding duration drops below two minutes: a new on-chain capital landscape in high-frequency payment scenarios

On-chain data analytics firm AIXBT’s data shows that the average holding time of stablecoins on the Solana network plummeted from 29 hours to 70 seconds within 24 months, a decrease of over 99%. After this data was reported by CoinDesk, it quickly triggered a market reassessment of the usage patterns on the Solana network. A 70-second holding duration indicates that stablecoins on Solana are almost continuously flowing—funds are transferred to the next destination before a wallet address can hold them for two minutes.

From a broader perspective, approximately one trillion dollars in stablecoin transactions per month are circulating through Solana at a velocity of 70 seconds, which cannot be explained by typical speculative holding behaviors. The shorter the average holding period of stablecoins, the more it suggests that the funds are closer to being “bridge capital” in payment scenarios rather than “reserve assets.” When the on-chain holding time shrinks to minutes, the fundamental nature of the funds has undergone a transformation.

What does the second-level holding duration reveal about the economic implications of fund circulation?

The most direct indicator of whether an asset has payment attributes is not its market cap, but its velocity. The shorter the holding period and the higher the circulation frequency, the closer it is to the core function of money. The reduction of stablecoin holding time to 70 seconds on Solana means that funds are moving through the network at a pace close to real-time settlement—they are no longer static digital dollars stored in user accounts but are a continuously flowing value carrier.

This “high turnover, low retention” pattern of fund behavior corresponds to typical real-world usage scenarios. If stablecoins were merely risk-hedging assets or speculative tools, market participants would tend to hold them long-term; however, data from Solana shows that funds are being used at high frequency for cross-border payments, merchant settlements, DeFi interactions, and on-chain payments. Data from on-chain payment activity in 2026 further confirms this: high-frequency, small-value, repetitive transactions are characteristic of actual payment operations rather than liquidity manipulation. When the holding time is compressed to minutes, Solana’s network positioning has shifted from an “asset storage layer” to a “funds circulation layer.”

How did the sharp decline in stablecoin holding time drive network value growth?

The sudden drop in holding time is not an isolated phenomenon but occurs in tandem with the overall expansion of Solana’s stablecoin ecosystem. In February 2026, the stablecoin transaction volume on Solana reached approximately $650 billion, surpassing Ethereum and TRON for the first time, ranking first globally in stablecoin transfer volume. In March of the same year, Solana’s total stablecoin supply exceeded $15.58 billion, handling about 36% of the global stablecoin transaction volume. USDC transfers alone increased by 300% year-over-year. By the first quarter of 2026, Solana processed 10.1 billion transactions in a single quarter, setting a new record.

These data points form a clear growth chain: shorter holding times → faster fund circulation → rising transaction volume → increased network utilization density. As funds circulate more rapidly on the network, the same amount of stablecoin supply can support larger transaction volumes, significantly improving Solana’s capital efficiency as a payment infrastructure.

Why did Circle mint $9.5 billion USDC on Solana in one month?

In April 2026, Circle minted $9.5 billion USDC on Solana, bringing the total minted in the year to $38 billion. This scale of minting signals two key points: first, the on-chain demand for native USDC on Solana is expanding rapidly; second, Circle regards Solana as a core deployment network in its multi-chain USDC strategy.

From the supply structure, USDC has become the dominant stablecoin on Solana, accounting for about 67% of the total supply. Out of Circle’s total USDC supply of over $79 billion, more than 10% is deployed on Solana, a proportion much higher than two years ago. Data from February 2026 shows that USDC accounts for about 70% of all stablecoin transfers on Solana, with a total network transfer volume of approximately $1.8 trillion out of the total $1.8 trillion in network transfers. The large-scale minting on the supply side and high-frequency usage on the demand side form a positive feedback loop, making Solana one of the most active settlement networks within the USDC ecosystem.

How does Solana leverage its low-cost, high-frequency advantages to support payment applications?

Solana’s competitiveness in payment scenarios is built on three core metrics: transaction confirmation time of about 392 milliseconds, typical per-transaction fees below $0.001, and a real-time throughput of several thousand transactions per second. These performance parameters enable Solana to handle transaction volumes comparable to traditional payment networks.

At the institutional application level, companies like Visa, PayPal, Stripe, Western Union, and Fiserv are deploying cross-border remittances, merchant settlements, and global payroll services based on Solana. Western Union has chosen Solana as the payment platform for USDPT stablecoin, and two U.S. banks are directly settling native USDC on Solana. On the consumer side, Jupiter has launched on-chain payment cards integrated with the Visa network, allowing users to spend USDC from their Solana wallets at any merchant accepting Visa. The Tether-backed mobile wallet Oobit has also integrated with Phantom Wallet, enabling over 15 million users to access the Visa payment network.

Additionally, the adoption of non-USD stablecoins on Solana is accelerating. The euro stablecoin EURC issued by Circle and the Brazilian real stablecoin BRZ issued by Transfero are driving a near 200% year-over-year increase in the number of monthly unique senders of non-USD stablecoins on Solana, reflecting the network’s increasingly clear infrastructure positioning in regional cross-border payments.

How do institutional capital and RWA adoption promote Solana’s upgrade as a settlement layer?

The expansion of Solana’s stablecoin ecosystem is synergistic with the growth of institutional-grade applications. By April 2026, the RWA (Real-World Asset) lending volume on Solana reached $1.23 billion, accounting for 99% of the pre-IPO equity trading volume in tokenized listings. B2C2 has designated Solana as the core network for institutional stablecoin settlement, citing its speed, reliability, and scalability as meeting key institutional needs. Spot Solana ETFs began trading in 2025, with Bitwise’s BSOL recording a first-day trading volume of $220 million.

In terms of liquidity, Solana’s derivatives open interest increased from $4.9 billion to nearly $6 billion, reflecting bullish trader expectations and also raising the risk of cascading liquidations. The $6 billion in derivatives leverage on Solana, combined with $15.58 billion in stablecoins, creates an on-chain capital cycle: stablecoins serve as collateral for leveraged positions and are recycled through liquidations back into the spot market. This cycle enhances the flow density of funds on Solana but also means that during market volatility, the circulation speed of stablecoins could accelerate further, intensifying the efficiency of liquidation transmission.

How is the focus of on-chain payment infrastructure competition shifting?

The sharp decline in stablecoin holding time reflects a shift in the competitive logic of the entire crypto payment infrastructure. In 2025, stablecoins processed approximately $33 trillion in transactions—more than twice Visa’s annual transaction volume. The industry’s competitive focus is shifting from “which network has larger stablecoin supply” to “which network has higher stablecoin circulation efficiency.”

Solana’s differentiated advantage in this competition lies in its performance parameters, which directly benchmark traditional payment settlement standards. The network processes over $2 trillion in stablecoin transfers quarterly, with per-transaction fees only a few cents, and final confirmation times measured in milliseconds. This predictable, stable, low-cost, and high-efficiency environment is highly valued in enterprise financial models. When Visa runs stablecoin settlement systems across four blockchains, Solana is among the first to be included, further confirming that the payment infrastructure race has moved from “who can issue tokens” to “who can process fund flows faster, cheaper, and more reliably.”

What sustainability risks does Solana’s high-frequency settlement system face?

The high-frequency fund circulation driven by the reduction of holding time to seconds also presents new operational challenges for Solana. The first key issue is whether the network can maintain stable throughput under sustained high-frequency settlement. Currently, Solana handles about 150 million transactions daily, with a real-time throughput of several thousand per second, but as payment applications expand and user scale grows, marginal performance pressures will emerge.

The second risk concerns whether the growth of stablecoin supply can continue to meet the actual demand of high-frequency payment scenarios. The $9.5 billion USDC minted on Solana in April 2026 is substantial, but if future minting volume cannot sustain this level, the current circulation speed may not be maintained.

The third risk involves the system’s vulnerability due to rapid stablecoin circulation. When funds flow at 70 seconds per cycle, any single point of failure—be it technical glitches, network congestion, or security breaches—could be rapidly amplified into widespread fund freezes or losses. The high-frequency settlement system demands infrastructure reliability far beyond traditional blockchain applications.

Summary

The average stablecoin holding time on Solana has plummeted from 29 hours to 70 seconds over two years, and Circle minted $9.5 billion USDC on Solana in April 2026. These two data points jointly indicate that stablecoins on Solana are shifting from a “reserve asset” model toward a “payment-oriented” model. The second-level holding duration of seconds signifies that funds are circulating at a very high frequency on-chain, corresponding to real-world use cases such as cross-border settlements, merchant payments, DeFi interactions, and card network spending. On the institutional adoption front, integration by Visa, Western Union, and U.S. banks further confirms Solana’s positioning as a production-grade payment infrastructure. Meanwhile, the high-frequency settlement system raises higher demands on network stability, supply sustainability, and system security. In the 2026 stablecoin landscape, a key metric for blockchain value is shifting from static supply size to dynamic circulation efficiency—data changes in this dimension are reshaping the underlying logic of on-chain USD payments.
