On-Chain Evidence Secures Convictions of Three Terrorism Financiers in Indonesia

Three individuals were convicted for terrorism financing in Indonesia during 2024–2025, with on-chain cryptocurrency evidence playing a central role, according to TRM Labs. Courts accepted wallet addresses, transaction histories, and blockchain flows as admissible evidence, demonstrating a shift toward recognizing digital assets in legal proceedings.

Indonesian authorities traced one defendant sending over $49,000 in USDt across 15 transactions from a local exchange to an international platform. The funds were ultimately routed to an ISIS-linked fundraising campaign in Syria. Analysis was conducted by Indonesia’s financial intelligence team and Densus 88, whose findings were accepted by the courts.

TRM Labs highlighted that similar capabilities are emerging across Southeast Asia, with agencies in Singapore and Malaysia developing blockchain intelligence to trace illicit finance.

The firm noted that stablecoin based illicit transfers reached approximately $141 billion in 2025, marking a five-year high. This trend underscores the growing importance of blockchain analytics in countering terrorism financing and other crypto-related crimes in the region.
