Stablecoins have solidified their position as foundational infrastructure in the cryptocurrency and web3 ecosystem, enabling everyday payments and settlements far beyond speculative trading. According to a detailed analysis released by blockchain analytics firm TRM Labs, 2025 represented a pivotal year for these assets. Monthly transaction volumes repeatedly surpassed $1 trillion, reflecting accelerated growth and mainstream integration across multiple blockchains.
The report highlights a consistent upward trajectory in stablecoin activity.
Volumes built steadily in the first half of 2025 before surging sharply later in the year.
Even after modest late-year declines, levels remained well above those seen in 2023 and most of 2024.
This sustained momentum underscores stablecoins’ evolution into reliable rails for real-world financial operations, offering speed, low costs, and protection from price swings that traditional volatile cryptocurrencies cannot match.
Yet the report also paints a nuanced picture of risk.
In 2025, wallets associated with illicit actors received roughly $141 billion in stablecoin transfers—the highest figure in at least five years.
Of that total, about $72 billion involved the ruble-pegged A7A5 token. Sanctions evasion emerged as the dominant driver, comprising 86 percent of all illicit cryptocurrency flows.
When excluding A7A5-related activity, stablecoins still accounted for 42 percent of overall volumes and an outsized 86 percent of illicit ones.
Crucially, the analysis reveals that misuse is not widespread but intensely concentrated.
Professional laundering networks and sanctions-bypassing operations dominate stablecoin-related crime.
Guarantee services—specialized facilitators that help move funds for high-volume clients—exploded from less than $1 billion per quarter in 2022 to peaks above $17 billion in mid-2025.
Nearly 99 percent of this activity flowed through stablecoins before enforcement actions against key players like Huione and Haowang Guarantee triggered a sharp drop.
Front-company exchanges such as Zedcex and Zedxion further illustrate the pattern.
Between 2024 and 2025, 83 percent of their incoming volume arrived in USDT, positioning them less as retail trading platforms and more as efficient value-transfer intermediaries for restricted actors.
The A7 network stands out as a prime example: this cross-border payment platform, linked to sanctioned Russian exchanges like Garantex and Grinex, processed at least $83 billion in direct volume.
Operating as a de facto parallel financial system, it routes funds for entities in Russia, Iran, North Korea, Venezuela, and elsewhere using stablecoins for seamless settlement outside conventional oversight.
TRM Labs notes that stablecoin adoption varies sharply by crime category. Near-total reliance appears in industrialized laundering and sanctions evasion, while scams, ransomware, and opportunistic offenses show more selective use.
This concentration allows illicit networks to operate at scale with remarkable efficiency.
As policymakers debate stablecoin regulations—from potential interest-bearing products in the United States to tighter controls in China—the TRM findings carry clear implications.
TRM Labs further explained that these so-called stablecoins now function as dual-use technology: essential for legitimate global finance yet critical enablers for a narrow but sophisticated set of high-risk actors.
Targeted enforcement focused on these concentrated networks, combined with ongoing monitoring of emerging fiat-pegged tokens in constrained jurisdictions, will be key to balancing responsible innovation with security.
TRM Labs concluded that with stablecoins now firmly embedded in the crypto economy, the path forward requires precision. Broad adoption seemingly brings opportunity; concentrated risks demand focused vigilance.
