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

On-chain data analysis firm AIXBT’s data shows that the average holding time of stablecoins on the Solana network dropped sharply 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 re-evaluation of the usage patterns on the Solana network. A 70-second holding duration implies that stablecoins on Solana are almost in a state of continuous circulation—funds are transferred to the next destination before remaining in a single address for more than two minutes.

From a more macro perspective, approximately 1 trillion USD worth of stablecoin transactions per month are passing through the Solana network at a circulation speed of 70 seconds, which cannot be explained by typical speculative holding behaviors. The shorter the average holding period of stablecoins, the more it indicates that the funds on the network are closer to “bridge funds” in payment scenarios rather than “reserve assets.” When the on-chain holding time shortens to minutes, its nature has undergone a fundamental 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 market capitalization, but the velocity of circulation. 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 a continuously circulating value carrier.

This “high turnover, low retention” fund behavior pattern corresponds to typical real-world usage scenarios. If stablecoins are 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 activities in 2026 further confirms this judgment: high-frequency, small-value, repetitive transaction structures 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 “asset storage layer” to “funds circulation layer.”

How the sharp decline in stablecoin holding time drives network value growth

The sudden drop in holding time is not an isolated phenomenon but occurs in tandem with the overall expansion of the Solana stablecoin ecosystem. In February 2026, the stablecoin transaction volume on Solana reached approximately 650 billion USD, surpassing Ethereum and TRON for the first time, ranking first globally in stablecoin transfer volume. In March of the same year, the total supply of stablecoins on Solana exceeded 15.58 billion USD, with the network handling about 36% of global stablecoin transactions, including USDC transfers which 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 form a clear growth chain: shorter holding times → faster fund circulation → increased transaction volume → higher network usage density. As funds circulate faster on the network, the same amount of stablecoin supply can support larger transaction volumes, significantly improving Solana’s capital utilization efficiency as a payment infrastructure.

Why did Circle mint 9.5 billion USD USDC monthly on Solana?

In April 2026, Circle minted 9.5 billion USD USDC on Solana in a single month, bringing the total minted in the year to 38 billion USD. 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 perspective, USDC has become the dominant stablecoin on Solana, accounting for about 67% of the total supply. Currently, Circle’s total USDC supply exceeds 79 billion USD, with over 10% 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 USD, of which USDC accounts for about 1.26 trillion USD. 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 in the USDC ecosystem.

How does Solana leverage 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, single transaction fees usually below 0.001 USD, and real-time throughput reaching thousands of transactions per second. These performance parameters enable Solana to handle transaction frequencies comparable to traditional payment networks.

At the institutional application level, Visa, PayPal, Stripe, Western Union, and Fiserv have already developed 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 US 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 Phantom Wallet natively, 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 have driven a near 200% year-over-year increase in the number of monthly independent senders of non-USD stablecoins on Solana, reflecting an increasingly clear infrastructure positioning for cross-border regional payments.

How institutional capital and RWA adoption are upgrading Solana’s settlement layer positioning

The expansion of Solana’s stablecoin ecosystem is synergistic with the growth of institutional-level applications. By April 2026, the RWA (real-world asset) lending volume on Solana reached 1.23 billion USD, accounting for 99% of tokenized pre-IPO equity trading volume. B2C2 has designated Solana as the core network for institutional stablecoin settlement, believing that its speed, reliability, and scalability meet key institutional needs. Spot Solana ETFs have been trading since 2025, with Bitwise’s BSOL reaching a first-day trading volume of 220 million USD.

In terms of liquidity, Solana derivatives open interest has increased from 4.9 billion USD to nearly 6 billion USD, reflecting traders’ bullish expectations and also posing risks of cascade liquidations. The 6 billion USD in derivatives leverage on Solana, combined with 15.58 billion USD in stablecoin supply, forms 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 circulation 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 the shift in on-chain payment infrastructure competition is occurring

The sharp decline in stablecoin holding time reflects a shift in the competitive logic of the entire crypto payment infrastructure. In 2025, stablecoins processed about 33 trillion USD in transactions—more than twice Visa’s annual transaction volume. The industry’s 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 directly comparable to traditional payment settlement standards. The network processes over 2 trillion USD in stablecoin transfers each quarter, with single transaction fees only a few cents and final confirmation times measured in milliseconds. This predictable, stable low-cost, 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 challenges for Solana’s operation. Whether the network can maintain stable throughput under sustained high-frequency settlement is the first key issue. Currently, Solana’s daily transaction volume is about 150 million, with real-time throughput reaching thousands of transactions per second, but as payment applications further proliferate and user scale continues to grow, the marginal pressure on network performance will gradually become apparent.

The second risk concerns whether the growth of stablecoin supply can sustainably match the real demand for high-frequency payments. The large-scale minting of 9.5 billion USD USDC on Solana in April 2026 raises questions about whether future minting can be maintained at this level, and whether the current circulation speed can be sustained.

The third risk stems from the system fragility caused by excessively rapid stablecoin circulation. When funds flow at 70 seconds per cycle, any single technical failure, network congestion, or security vulnerability could be rapidly amplified into widespread fund stalls or losses. The high-frequency settlement system demands infrastructure reliability far beyond traditional blockchain applications.

Summary

The average stablecoin holding time on Solana plummeted from 29 hours to 70 seconds over two years, and in April 2026, Circle minted 9.5 billion USD USDC on Solana. These two data points jointly point to a conclusion: stablecoins on Solana are shifting from “asset reserve” to “payment orbit.” The second-level holding time indicates 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 level, the involvement of Visa, Western Union, and US 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 evaluating a blockchain’s value is shifting from static supply size to dynamic circulation efficiency—data changes on Solana are reshaping the underlying logic of on-chain USD payments.
