Indonesian courts convicted three individuals for financing terrorism in 2024 and 2025, using serial evidence as the backbone of each trial.
These cases represent a clear shift in how Southeast Asian courts deal with blockchain data, with wallet addresses and transaction histories now serving as admissible and probative evidence of a case.
How Blockchain Data Built the Case
Indonesia’s financial intelligence unit, PPATK, worked alongside the country’s elite counter-terrorism police unit, Densus 88, to trace cryptocurrency transactions linked to the three defendants.
None of the individuals The attacks were carried out directly. Instead, they collected, converted, and converted funds into cryptocurrencies to move funds to terrorist networks.
One defendant sent more than $49,000 worth Tether (USDT) Over 15 transactions from a local Indonesian exchange to a foreign exchange.
These funds were later directed to an ISIS-linked fundraising campaign in Syria, according to TRM Labs.
“Indonesian courts have demonstrated that evidence related to cryptocurrencies… is not only admissible, but can also solidify a terrorism financing prosecution.” He reads Excerpt from TRM Laboratories report.
A regional trend is taking shape
Indonesia is not acting alone. TRM Labs noted that Singapore, Malaysia, and other jurisdictions in Southeast Asia are all investing in blockchain intelligence capabilities.
The company described a broader regional pattern in which terrorist cells have turned to cryptocurrencies precisely because regulators have been slow to apply the same scrutiny they provide to traditional fiat channels.

Xiong was extradited to China, where he faces charges of fraud and money laundering. His arrest came three months after the arrest of Chen Qi, chairman of the Prince Group, which runs the Huiyun Group.
TRM separately reported in February that illicit entities received nearly $141 billion worth of stablecoins in 2025, the highest level in five years. Sanctions-related activities It accounts for 86% of all illicit cryptocurrency flows That year.
These Indonesian convictions suggest that the window for using cryptocurrencies to quietly fund terrorism is closing, especially as courts across the region accept blockchain data as trial-ready evidence.
