Onchain evidence played a crucial role in the conviction of three individuals for terrorism financing in Indonesia during the years 2024 and 2025. This development signifies a notable shift in how courts are beginning to recognize the value of onchain evidence. According to TRM Labs, Indonesian courts have established that cryptocurrency-related evidence, including wallet addresses, transaction histories, and on-chain flows, is not only admissible in court but can also serve as a foundational element in terrorism financing prosecutions.
TRM highlighted that terrorism financing networks have increasingly favored cryptocurrency as a means to transfer funds, largely due to the slow response from authorities and regulators in scrutinizing these transactions with the same rigor as traditional fiat channels. However, this trend is changing, as demonstrated by the recent cases in Indonesia.
In one instance, authorities traced a defendant who transferred over $49,000 worth of USDt across 15 transactions from a local exchange to a foreign platform. The funds were subsequently linked to an ISIS-affiliated fundraising campaign in Syria. The analysis conducted by Indonesia’s financial intelligence team and the counterterrorism police unit, Densus 88, was pivotal in presenting blockchain data as key evidence in each of the three cases brought before the courts.
Moreover, TRM Labs noted that Indonesia is not alone in Southeast Asia in utilizing blockchain analytics to combat financial crimes. Similar trends are emerging across the region, with governments investing in blockchain intelligence capabilities and fostering collaboration between public and private sectors to tackle illicit finance risks.
Countries like Singapore and Malaysia are also enhancing their technical capacities to trace cryptocurrency flows, as their financial intelligence units and law enforcement agencies recognize the importance of adapting to the evolving landscape of financial crime.
In a related context, on April 1, authorities in Cambodia and China apprehended Li Xiong, a leader of an organization involved in scam operations that exploited victims through fraudulent investment schemes. His extradition to China for fraud and money laundering charges highlights the ongoing efforts to address illicit activities linked to cryptocurrency.
TRM reported that illicit entities received approximately $141 billion worth of stablecoins in 2025, marking a significant increase over the past five years. This statistic underscores the urgent need for enhanced regulatory frameworks and enforcement mechanisms to mitigate the risks associated with cryptocurrency in the context of terrorism financing and other criminal activities.
