Indonesian courts accept on-chain crypto evidence, convict three terrorism financiers

Indonesia convicted three people for terrorism financing in 2024–2025. Courts accepted on‑chain evidence as primary proof, per TRM Labs.

PPATK and Densus 88 ran the blockchain analysis. Judges treated wallet maps and traced flows as central evidence, not background. TRM Labs calls this the first such use in Indonesia and likely Southeast Asia.

One defendant sent over $49,000 in USDT to a foreign exchange. Funds then moved to an ISIS-linked campaign, according to TRM Labs.

Indonesia built the toolkit since 2021. PPATK launched the SIPENDAR platform and enforced KYC/AML on local VASPs, per TRM Labs and PPATK.

In 2023, TRM Labs flagged ISIS-affiliated networks in Indonesia using USDT on Tron for cross‑border transfers. Exchange KYC, obtained via legal process, tightened attribution.

How investigators traced the $49k:
- Identified the suspect’s wallet on-chain
- Followed outbound transfers to an exchange deposit
- Matched the deposit to exchange KYC via MLAT or equivalent
- Linked the named account to the designated recipient

The lineage goes back to 2017. PPATK tied ISIS member Bahrun Naim to Bitcoin distribution via PayPal, per TRM Labs. In 2022, U.S. Treasury sanctions named five Indonesians who routed over $517,000 through local exchanges to ISIS wallets in Syria, often in $10,000 tranches masked as aid, according to the same source.

The 2024–2025 verdicts mark the first convictions from that effort. Roughly seven years passed from first public allegation to court-proven cases, per TRM Labs.
