A new report by blockchain intelligence company TRM Labs showed that crypto-related crime had a record nominal value in 2025, albeit that the proportion of illicit activity in the wider digital asset economy kept dropping as a whole.
The report estimates that the volume of illegitimate cryptocurrencies had risen to $158 billion in 2025, 145% higher than the figure of a year ago, which was $64.5 billion.
Although the dollar terms increased sharply, the illicit transactions formed only 1.2% of the entire on-chain volume, compared to 1.3% in 2024 and much less than the 2.4% high in 2023.
These numbers are generally in line with the estimates released this month by Chainalysis, which estimated crypto crime at $154 billion in 2025 as being less than 1% of total crypto activity.
To better capture risk, TRM introduced a new metric that measures illicit activity relative to deployable capital rather than raw transaction volume.
Through this method, the company discovered that the illicit players took 2.7% of the liquidity of the crypto in 2025 compared to 2.9% the year before and 6.0% the year before.
TRM said the data suggest that while certain illicit categories expanded in absolute terms, criminal actors absorbed a smaller proportion of new capital entering the ecosystem.
In 2025, activity related to sanctions had led to the illicit volume, mostly associated with Russia-related flows. TRM credited the growth to the increased use of A7A5, a ruble-pegged stablecoin that transacted a total volume of more than $72 billion throughout the year.
At least $39 billion of transactions were correlated to wallets belonging to the Russian sanctions-evasion system A7, suggesting a high level of coordination of an activity related to state-consistent financial infrastructure, instead of extensive use of the market.
Stablecoins were the main vehicle, and the activity moved to less regulated and riskier channels as enforcement increased.
Cryptography was reconfigured by geopolitical pressures that influenced several areas, as Venezuelans have turned into major users of stablecoins and peer-to-peer transactions to pay their daily income, remittances, and informal services due to the lack of economic stability.
In Iran, crypto buying and selling activities have been resilient to sanctions, with the total volume of transactions decreasing in the June 2025 Iran-Israel war, yet values went up, indicating larger transfers, with illegal operations reaching up to $580 million.
