Do Kwon, the co-founder of Singapore-based Terraform Labs, was sentenced to 15 years in a US prison after pleading guilty to fraud over the 2022 collapse of the TerraUSD stablecoin that erased about US$40 billion in value.
Terraform Labs was the company behind TerraUSD, an algorithmic stablecoin designed to hold a one-dollar peg, and its sister token Luna. In May 2022 the peg snapped, triggering a death spiral that vaporised tens of billions of dollars within days. Ordinary investors lost life savings, and the shockwaves toppled major firms including Three Arrows Capital, helping plunge the entire crypto industry into a brutal winter.
Kwon, a South Korean national who had been based in Singapore, left the city-state as authorities in multiple countries closed in. South Korean prosecutors obtained an arrest warrant, Interpol issued a red notice, and in February 2023 the US Securities and Exchange Commission charged him with orchestrating a multi-billion-dollar crypto asset securities fraud. The SEC alleged he had misled investors about how the stablecoin maintained its peg.
In March 2023 Kwon was arrested at Podgorica airport in Montenegro while attempting to board a flight using forged travel documents, receiving a four-month local sentence for the document offence. He then fought extradition for nearly two years before Montenegro's justice minister chose the American request over South Korea's, and Kwon was handed to FBI agents on December 31, 2024.
The civil reckoning came first: in April 2024 a Manhattan jury found Kwon and Terraform liable for securities fraud, and that June a court approved a settlement requiring more than US$4.5 billion in disgorgement, interest and penalties, plus a personal civil fine for Kwon and a ban from crypto trading. Then, in August 2025, Kwon changed his plea and admitted guilt to wire fraud and a fraud conspiracy count. Victims gave emotional testimony at sentencing about their financial ruin, and the court imposed a 15-year term, signalling that the scale of the damage demanded serious punishment.
For Singapore, where Terraform Labs was headquartered and where the Monetary Authority cooperated with US investigators, the case underscored how the city-state's crypto ambitions collided with its zero-tolerance instincts on financial misconduct.
Kwon's case also became a landmark for cross-border crypto enforcement. South Korea continued to pursue its own charges, and the American civil judgment earmarked billions for investor recovery through Terraform's bankruptcy estate. Legal analysts said the 15-year sentence, one of the harshest ever imposed on a crypto founder, would be studied for years as regulators worldwide weighed how to punish fraud in decentralised markets.
