South Korea’s National Police Agency has made the Tether Laundromat a stated enforcement priority as authorities move against unregistered crypto exchange offices. Police say these offices are helping criminal groups convert fraud proceeds into USDT and send funds overseas.
National Police Agency Director Park Sung-ju announced the plan during a press briefing in Seodaemun-gu, Seoul. He said police will increase investigations into crypto exchange offices operating without registration.
Korean Police Target USDT Laundering Route
These offices are suspected of helping voice phishing groups move stolen won into Tether. The funds are then sent abroad through crypto wallets, often beyond the immediate reach of Korean authorities.
Park also said police will prepare specialized training for virtual asset investigations. The Financial Intelligence Unit will work with police on the training effort.
The Tether Laundromat term describes a stablecoin-based laundering method now under Korean police focus. The model uses unregistered exchange offices as the first conversion point between local currency and USDT.
Voice phishing groups first steal won-denominated funds from Korean victims. Those funds are then moved to informal crypto exchange offices in Seoul. The offices convert the money into USDT, often using the Tron network because of low fees.
After conversion, the USDT is sent to overseas wallets. These wallets may be controlled by foreign operators connected to the fraud groups.
Seoul Exchange Offices Face Scrutiny
Police are focusing on the spread of unregistered exchange offices across Seoul. Many of these operations appear to work outside formal compliance systems.
Authorities say the offices give criminal groups a fast way to move money out of the banking system. Once the stolen funds become USDT, transfers can happen around the clock.
The Tether Laundromat model has gained attention because the full process can be completed within hours. That speed makes recovery harder for victims and investigators.
USDT on Tron Drives Laundering Risk
The use of USDT on Tron is central to the reported laundering method. Tron-based transfers are known for low fees and fast settlement. These features can make the network useful for legitimate payments.
However, the same features can also support criminal fund movement. Police say criminals can move stolen money overseas without relying on banks after the domestic conversion stage.
The challenge for Korea is timing. Investigators must identify suspicious wallets before funds are split, moved again, or cashed out in weaker enforcement regions.
Police Plan Crypto Training
South Korea’s Criminal Proceeds Tracking Team will begin formal crypto-asset tracking training in the second half of 2026. Around ₩100 million has been allocated for related work.
Continuous training for crypto-focused investigators will also follow. The FIU is expected to be a main partner in the effort.
The plan shows that authorities are trying to build long-term investigative capacity. It also shows that crypto laundering is moving from a specialist issue into mainstream police enforcement.
DSJ Case Shows Faster Private Response
The Korean announcement follows another stablecoin enforcement case linked to DSJ Exchange and BG Wealth Sharing. According to the supplied report, investigator ZachXBT worked with Tether, Binance Security, OKX, and U.S. law enforcement during a 72-hour action.
That operation froze $41.5 million in fraud proceeds. About $38.4 million in USDT was blacklisted directly by Tether across 19 Tron addresses. Another $3.1 million was frozen through Binance, OKX, and U.S.-controlled wallets.
The case showed how quickly private-sector crypto enforcement can act when suspicious addresses are identified. Korea’s effort shows how national police agencies are preparing to build similar capacity at scale.
Tether Freeze Function Becomes Key
Tether can freeze USDT held at flagged addresses through controls built into its smart contract. This makes USDT different from some other crypto assets.
That feature can help enforcement when investigators identify wallets quickly. It can also make every won-to-USDT conversion point important for Korean police.
The Tether Laundromat crackdown may depend on how fast authorities can trace funds and coordinate with Tether. Delays could allow funds to move through more wallets or into jurisdictions with weaker controls.
Licensed Exchanges May Face Pressure
Korean licensed crypto exchanges may also become important to the investigation. Upbit, Bithumb, Coinone, and Korbit could help identify patterns linked to suspicious USDT flows.
Police may look for small repeated transfers, unusual wallet behavior, or links to known exchange-office activity. Voluntary disclosures from licensed platforms could help authorities build stronger cases.
The Tether Laundromat issue also puts pressure on regulators to close gaps between registered exchanges and informal money-changing operations.
Conclusion
South Korea’s focus on the Tether Laundromat marks a sharper approach to stablecoin-era financial crime. Authorities are no longer treating crypto laundering as a secondary issue.
The won-to-USDT conversion point is now a direct enforcement target. The outcome will depend on arrests, wallet tracing, Tether coordination, and cooperation from local exchanges. If those steps advance, Korea could build a more active model for fighting stablecoin laundering.
