Terra (blockchain)

• 1. Introduction

  ›

  In May 2022, Terra's two central tokens, TerraUSD and LUNA, lost almost $45 billion in market capitalization within a single week. The blockchain protocol had been created four years earlier by Do Kwon and Daniel Shin. Their goal was to power a payment system built around algorithmic stablecoins. These were digital currencies designed to maintain their value through mathematics rather than dollar reserves. Before the crash, TerraUSD ranked as the third largest stablecoin in the world by market capitalization. What made this system so attractive to investors, and what made it so vulnerable to sudden collapse, deserves a careful look. The consequences stretched from Seoul to Singapore to a Montenegro airport, and eventually to a federal courtroom in the United States.

• 2. The Two-Token Design

  ›

  The phrase "burn and mint equilibrium" captured the core logic that distinguished Terra from conventional stablecoins. Traditional stablecoins hold actual dollars in reserve for every token they issue. Terra's design had no such collateral. Instead, it relied on a relationship between two tokens. TerraUSD, known as UST, was designed to stay fixed at one U.S. dollar. LUNA was designed to absorb the volatility that UST was not permitted to show. When demand for UST rose, new UST tokens were created while an equivalent value of LUNA was destroyed. When demand fell, the process ran in reverse.

  Terra used a proof-of-stake codesign for its consensus mechanism. LUNA also served as a governance token, giving holders a vote on proposals submitted to the Terra community. Several stablecoins beyond UST were built on the protocol, each named for the currency it tracked. Three decentralized applications, known as DApps, ran on the Terra blockchain using its stablecoin infrastructure: Anchor, Mirror, and Pylon. Of all these applications, Anchor would eventually attract the most attention. Critics would raise serious concerns about one of its central features.

• 3. Building an Empire

  ›

  In 2019, Terraform Labs launched its first cryptocurrency token, a year after the company's incorporation in Seoul, South Korea. The project attracted significant investment. More than $200 million flowed in from firms including Arrington Capital, Coinbase Ventures, Galaxy Digital, and Lightspeed Venture Partners.

  In January 2022, the Luna Foundation Guard was established as a non-profit based in Singapore, with Do Kwon as its director. Terraform Labs directed a portion of its UST sales revenue to the Foundation to use as reserves for stabilizing the price of UST. By the 7th of May 2022, just days before the crisis, those reserves included 80,394 bitcoin, valued at approximately $2.4 billion. The Foundation also held various other stablecoins and cryptocurrencies.

  In February 2022, Terra announced a sponsorship deal with the Washington Nationals Major League Baseball team. The arrangement included stadium and television branding and renamed the club's lounge the "Terra Club." Kwon had first brought the proposal to the Terra community without naming the partner. He referred to it only as an unnamed "sports franchise in one of the four major American professional sports leagues." The community approved a payment of $38.15 million for a five-year exclusive partnership.

  Do Kwon and Daniel Shin each initially held one share of Terraform Labs, giving each a 50% stake in the company. Kwon later enlarged his share pool to eleven shares, raising his ownership to 91.7% and reducing Shin's to 8.3%. On the 18th of May 2022, Shin and his payment company Chai Corporation announced he no longer held any Terraform Labs shares. Documents from Singapore's Account and Corporate Regulatory Authority told a different story, showing Shin still held 8.3% as of that date. Those same documents revealed that Shin held 51.2% of Chai Holdings, the parent company of Chai Corporation, while Kwon held 22.4%. The Anchor lending protocol, meanwhile, was drawing deposits at a pace that critics found difficult to explain.

• 4. The Anchor Protocol

  ›

  A 19.45% annual yield on UST deposits was the number that defined Anchor Protocol's appeal. Investors who placed UST into Anchor received that return, paid from Terra's own reserves. Critics raised concerns from an early stage. Some characterized Kwon's stablecoin model as functioning like a "ginormous Ponzi scheme," arguing that the yield was sustainable only as long as new capital kept flowing in.

  Mirror Protocol, another application running on the Terra chain, offered a different category of risk. It designed and offered financial derivatives built to track, or "mirror," the prices of actual listed stocks, giving users exposure to equities without holding them directly.

  In 2021, the U.S. Securities and Exchange Commission issued a subpoena to Terraform Labs and Do Kwon specifically because of Mirror Protocol. The SEC regarded it as potentially offering unregistered securities. Kwon refused the subpoena. He announced he would sue the SEC instead. A court hearing in Manhattan in February 2022 ruled in favor of the SEC's right to continue its investigation. The formal SEC charges arrived in February 2023. Nine months earlier, UST had already lost nearly all its value in a single week.

• 5. When the Peg Broke

  ›

  Beginning on the 9th of May 2022, UST started to break from its one-dollar peg. Within days, its price fell to 10 cents. LUNA, which had traded at an all-time high of $119.51, collapsed to virtually zero. Before the crisis, LUNA had been among the top ten largest cryptocurrencies by market value. On the 13th of May 2022, Terraform Labs temporarily halted the Terra blockchain in response to the falling prices.

  The collapse appears to have been triggered by an attack on Terra's liquidity pool and was worsened by flaws in the underlying blockchain framework. Contributing factors included investor concerns about cryptocurrencies more broadly and a drop in the price of bitcoin. Large withdrawals from the Anchor Protocol in the days before the crash added further pressure. As holders rushed to convert UST into LUNA through the mint-and-burn system, LUNA's supply swelled dramatically. The increased supply drove LUNA's price down further, which destabilized the balancing mechanism between the two tokens. The Luna Foundation Guard spent its bitcoin and other cryptocurrency reserves in an attempt to restore the peg, but the effort failed. Blockchain analysts later noted that the precise fate of those reserves remained unclear.

  On the 25th of May 2022, the Terra community approved a proposal to reissue a new LUNA cryptocurrency and to abandon UST entirely. The original blockchain was renamed Terra Classic, and the original LUNA became LUNA Classic, abbreviated LUNC. Investors called the new token Terra 2.0. It lost value in its opening days on exchanges.

  In August 2022, Do Kwon discussed the collapse on the NFTV series Coinage. He acknowledged that his earlier faith in Terra now "seems super irrational." He denied that the system had ever been a Ponzi scheme. KBS News later reported that before the collapse, Kwon had transferred 9 billion won to the Seoul law firm Kim & Chang. That sum was worth $7 million, and federal prosecutors would later cite it in the case against him.

• 6. Arrest and Sentence

  ›

  On the 23rd of March 2023, Do Kwon attempted to travel to Dubai using false Costa Rican travel documents. He was also carrying false Belgian travel documents at the time. Montenegrin authorities intercepted and arrested him at Podgorica Airport.

  A federal grand jury in Manhattan subsequently brought eight charges against Kwon, including securities fraud, commodities fraud, wire fraud, and conspiracy.

  Terraform Labs filed for Chapter 11 bankruptcy on the 21st of January 2024. Assets and liabilities were listed in the range of $100 million to $500 million. In August 2025, Kwon pleaded guilty to two fraud charges and agreed to forfeit $19 million as part of a plea deal. The U.S. government argued for a sentence of no more than 12 years. On the 11th of December 2025, a judge sentenced him to 15 years in prison. In February 2026, the group managing Terraform Labs' bankruptcy sued Jane Street Capital, alleging insider trading and a role in the collapse. That lawsuit was the most recent of many legal actions that followed, stretching across courts in California, Singapore, South Korea, and France.

• 7. Global Legal Fallout

  ›

  On the 18th of May 2022, South Korea's new Justice Minister, Han Dong-hoon, enlarged the Seoul Southern District Prosecutor's economic crimes division. He vowed to track illegal funds, crack down on tax evasion, and seize the proceeds of criminal financial activity. On its first day of operation, the Financial and Securities Crimes Joint Investigation Team named the LUNA and Terra crisis as its primary target. In June 2022, the Korean government imposed travel restrictions on 15 people with connections to Terraform Labs. The group included former developers who had worked on the Anchor lending protocol. An arrest warrant for Daniel Shin followed on the 29th of November 2022.

  Kwon filed to dissolve Terraform Labs' Korean entity on the 30th of April 2022, according to records at the Supreme Court of Korea's Registry Office. Approval came on the 4th of May 2022. In Singapore, where Terraform Labs was incorporated, the company had never applied for a licence under the Payment Services Act. It was not a notified entity either, meaning it lacked even a temporary exemption from that licensing requirement from the Monetary Authority of Singapore.

  On the 17th of June 2022, plaintiffs filed a class action against Terraform Labs in federal court in California. In September 2022, a $56.9 million class action followed at the High Court of Singapore. The defendants in the Singapore case included Do Kwon, Terraform Labs, Nikolaos Alexandros Platias, and the Luna Foundation Guard.

  In December 2022, French cryptocurrency investors filed a criminal complaint against Binance. They accused the exchange of marketing on Instagram and Telegram before French authorities had approved its registration as a digital financial service. In April 2024, Binance's U.S. unit convinced a federal court to send a separate class action to arbitration. The plaintiff had purchased more than $437,000 in TerraUSD on Binance.US before the collapse. He alleged the exchange failed to disclose that UST was a security. In December 2024, Jump Trading's crypto unit, Tai Mo Shan Ltd., agreed to pay $123 million to the SEC. The settlement resolved claims that Tai Mo Shan had misled investors about the stability of TerraUSD. More than two years after the collapse, legal consequences were still accumulating for entities far beyond Terraform Labs itself.
