Ex-Singapore Naval Officer Sentenced to 82 Months in Crypto Theft Case

A former Singapore Armed Forces captain has been sentenced to 82 months in prison for stealing 1.7 million USDT from an acquaintance's cold wallet, according to court reporting published on May 8, 2026. The case highlights a basic but critical vulnerability in crypto self-custody: a seed phrase written on paper and left at home.

Teo Rong Xuan Sentenced to Six Years and 10 Months

Teo Rong Xuan, 35, pleaded guilty to six charges related to the theft, with another 10 similar charges taken into consideration during sentencing, CNA reported. Teo was a captain with the Naval Diving Unit before being discharged from the SAF. MINDEF confirmed to reporters that he was no longer serving.

The victim, Xuan Songtao, had deposited approximately 1.7 million USDT into a Ledger Nano X cold wallet on December 14, 2022. He wrote the device's 24-word seed phrase on paper and kept it at his home.

Teo re-entered the victim's condominium on December 31, 2022 using an access card. He photographed the seed phrase and, on January 1, 2023, transferred the full 1.7 million USDT into his own wallet. Court documents valued the stolen amount at approximately US$1.7 million (S$2.15 million).

The case was prosecuted as a conventional criminal matter, not a crypto-specific enforcement action. Charges included housebreaking, securing access to a cold wallet to commit theft, misuse of a computer system, and use of benefits from criminal proceeds.

Bail Set at S$130,000; Sentence Begins May 29

Judge Ong granted a three-week deferment of the sentence. Teo remained out on S$130,000 bail and is expected to begin serving the 82-month term on May 29, 2026.

At current market rates, USDT trades at $0.9998 with a market capitalization exceeding $189 billion. The stablecoin's peg stability means the stolen amount retains nearly the same dollar value today as when it was taken.

Why This Case Matters for Crypto Self-Custody

The theft did not involve a protocol exploit, exchange hack, or sophisticated on-chain attack. It was a physical breach: someone with access to a residence photographed a paper seed phrase. For holders who store recovery phrases at home, the case is a direct warning about physical security gaps in self-custody setups.

Singapore's handling of the case as standard criminal law, applying housebreaking and computer misuse statutes rather than crypto-specific regulation, reflects how many jurisdictions still prosecute digital asset theft. As governments worldwide sharpen their approach to stablecoin oversight, enforcement actions like this one show that existing criminal codes can already reach crypto-related offenses.

The 82-month sentence is notably severe for a theft case involving a single victim. The prosecution's position and the number of charges, 16 in total, suggest the court weighed the premeditation and abuse of trust involved. Teo had prior access to the victim's home, which enabled the break-in.

For the broader crypto industry, the case lands during a period when the movement of large sums across wallets continues to draw regulatory and public scrutiny. The Crypto Fear & Greed Index currently sits at 38, reflecting a cautious market mood.

The sentencing also arrives as stablecoin policy debates intensify in multiple jurisdictions. While this case is not a regulatory action, it adds to the growing body of criminal cases that involve stablecoins as the target asset rather than volatile tokens.

Teo's sentence is scheduled to begin on May 29, 2026. No appeal has been publicly reported.
