Do Kwon

• 1. Introduction

  ›

  Do Kwon named his newborn daughter Luna in April 2022, writing publicly: "My dearest creation named after my greatest invention." Within weeks, the cryptocurrency bearing that name had collapsed to virtually nothing. Almost $45 billion in market capitalization vanished in a single week. Investors around the world lost savings they had trusted to his creation. Then came the warrants, the flight, and an arrest far from Seoul. By late 2025, a federal court had sentenced Do Kwon to more than a decade in prison. How did a young engineer build something so large? And how did it all fall apart?

  ›

  Born in Seoul on the 6th of September 1991, Do Kwon attended Daewon Foreign Language High School. He then crossed the Pacific to study at Stanford University, earning a degree in Computer Science in 2015. After graduating, he spent a brief period working as a software engineer at both Microsoft and Apple. In January 2016, he returned to South Korea and founded a networking startup called Anyfi.

  Anyfi secured approximately $600,000 in South Korean government funding during its early stages. The funding was approved through a Korean incubator company run by one of the co-founders' parents, a direct conflict of interest. The Korean Ministry of SMEs and Startups later found that Anyfi had received failing grades in its initial evaluation reports. Ministry investigators also uncovered five counts of inappropriate use of funding for personnel expenses. The Ministry reported that the money was eventually retrieved.

  In January 2018, Kwon co-founded a new company with entrepreneur Daniel Shin. This venture would operate across borders and deal in a new form of digital money. In 2019, Forbes named Kwon to its 30 Under 30 list in the Asia Finance and Venture Capital category.

• 3. The Terra Ecosystem

  ›

  Terraform Labs Pte. Ltd. was incorporated in Singapore, placing it beyond the easy reach of any single regulator. In 2018, the company released a cryptocurrency called Luna. Starting in 2020, it began selling a stablecoin called TerraUSD, known as UST. Unlike stablecoins backed by dollar reserves, UST used an algorithm tied to the Luna supply to maintain a value of around one dollar.

  One dollar was the constant target for UST's value, sustained not by cash reserves but by its dynamic relationship with Luna. When UST fell below that floor, traders could exchange it for a dollar's worth of Luna. That exchange reduced the UST supply and pushed the price back up. When UST rose above the target, new coins could be created by burning Luna to expand the supply. Terraform Labs described this as an elastic monetary policy. By April 2022, Luna's value had climbed to more than $116.

  Mirror, whose token was known as MIR, ran on a decentralized finance platform connected to the Terra blockchain. It let users create and trade synthetic versions of stocks and other assets, effectively allowing people to work around restrictions that applied to those assets in conventional markets. Prism, Astroport, and Anchor were among the other projects Kwon's team built within the network.

  The U.S. Securities and Exchange Commission had taken notice of Mirror before the wider crisis arrived. In 2021, the SEC issued a subpoena to Terraform Labs and Kwon specifically about the Mirror Protocol. Kwon refused to comply and said he would sue the SEC instead.

  In December 2021, Korea's National Tax Service demanded approximately $100 million in additional taxes from Kwon and Shin. They refused to pay, arguing that their subsidiaries in Singapore and the British Virgin Islands were not Korean entities. Korean authorities maintained that the founders had made practical management decisions while resident in South Korea, making the profits subject to Korean jurisdiction. On the 30th of April 2022, Kwon filed to dissolve Terraform's Korean entity. The dissolution was approved on the 4th of May 2022. Three days after that, the unraveling would begin.

• 4. Seven Days of Collapse

  ›

  On the 7th of May 2022, several prominent investors reportedly sold more than $285 million worth of UST on Binance in a single day. That selling pressure broke the algorithm's grip. By the 8th of May, UST had slipped to $0.985, barely below its intended floor. The Luna Foundation Guard, established to serve as a reserve for Luna, loaned a total of $1.5 billion to try to defend the peg.

  Luna, which had reached an all-time high of $119.51, fell to virtually zero over the following days. UST plunged from near parity to just ten cents. In June 2022, Terraform Labs introduced a replacement coin called Luna 2.0. Investors and critics pushed back hard. The original coins were subsequently renamed TerraClassicUSD and LUNC.

  Around 200,000 South Korean investors had been harmed by the crash. By the 17th of May, more than 1,600 of them had signed up with domestic law firms to pursue a class action. A separate suit, Patterson v. TerraForm Labs Pte Ltd. et al., was filed on the 17th of June 2022 in the United States District Court for the Northern District of California. In September 2022, a $56.9 million class action was brought at the High Court of Singapore. Do Kwon, by then, was no longer in South Korea.

  ›

  On the 12th of May 2022, ten days into the collapse, a man arrived at Do Kwon's high-rise condominium building. He demanded an apology and claimed to have lost approximately $2 million. Kwon's wife requested emergency police protection, and South Korean police opened an investigation.

  In October 2022, on the Unchained Podcast, Kwon was asked about the South Korean government's move to cancel his passport. He answered: "Oh, I'm not using it anyway, so it doesn't, I can't see how that makes a difference to me." When asked if he had another passport, he declined to say. In 2023, he acknowledged holding a legitimate passport from Costa Rica.

  By the 14th of September 2022, a South Korean court had issued a formal arrest warrant for Kwon and five others on allegations of violating Korean capital markets law. Prosecutors placed all six in Singapore at the time. Days later, the Seoul Southern District Prosecutors' Office began the process of adding Kwon to Interpol's red notice list and revoking his passport. By December 2022, South Korean authorities believed he had moved to Serbia.

  On the 23rd of March 2023, police at Podgorica Airport in Montenegro stopped a man attempting to board a flight to Dubai. He was carrying falsified Costa Rican travel documents and a second set of falsified Belgian documents. The man was Do Kwon. A federal grand jury in Manhattan subsequently charged him on eight counts: securities fraud, commodities fraud, wire fraud, and conspiracy. One month later, KBS News reported that Kwon had transferred 9 billion won to the law firm Kim & Chang before the TerraUSD collapse. That sum was the equivalent of roughly $7 million.

• 6. Courts and Consequences

  ›

  On the 19th of June 2023, a Montenegrin court sentenced Kwon to four months in prison for using forged passports. Former Terraform Labs finance officer Han Chang-joon received the same sentence. Kwon appealed and lost before Montenegro's highest court.

  In November 2023, the Montenegro High Court approved Kwon's extradition to either South Korea or the United States. The justice minister initially chose South Korea. A series of appeals and counter-rulings followed over the next year. In December 2024, a Supreme Court ruling gave the justice minister final authority. Minister Bojan Bozovic ordered Kwon deported to the United States. Kwon was extradited on the 31st of December 2024.

  February 2023 had already brought formal SEC charges. The agency charged Kwon and Terraform Labs with perpetrating a multi-billion dollar crypto asset securities fraud. Terraform Labs filed for Chapter 11 bankruptcy on the 21st of January 2024, listing assets and liabilities between $100 million and $500 million. The civil case then went to trial. On the 5th of April 2024, a jury in the Southern District of New York found Kwon and Terraform Labs liable for defrauding investors. The SEC had argued that Kwon secretly sought outside financing after UST slipped from its peg in May 2021. He then publicly attributed the recovery to algorithmic stability alone, regulators said. The agency also said Kwon had falsely claimed his blockchain was being used for real transactions on South Korea's Chai app.

  In August 2025, Kwon pleaded guilty to two fraud charges and agreed to forfeit $19 million. The U.S. government argued for a sentence of no more than 12 years. A federal judge sentenced him to 15 years in prison on the 11th of December 2025. The South Korean special prosecution office separately revealed that Kwon had withdrawn approximately $35 million in cash even after his arrest in Montenegro. Documents from his confiscated laptop appeared to show that Kwon had provided financial support to Milojko Spajic. Spajic was a former Montenegrin finance minister and a prime ministerial candidate at the time. Kwon and his lawyers denied that allegation. If Kwon serves half of his sentence in the United States, he may apply for the International Prisoner Transfer Program. Under that arrangement, he could return to South Korea, where a second trial could still await him.
