Kwon Do-hyung, more commonly known as Do Kwon, is a South Korean former businessman and software engineer. He was the co-founder and CEO of Terraform Labs, the parent company of crashed stablecoin TerraUSD and cryptocurrency Luna. TerraUSD and Luna collapsed in May 2022, wiping out almost $45 billion market capitalization in one week and causing hundreds of billions in losses in the larger crypto market. Kwon faces legal and social pressure regarding his role in the Terra crash. Citizens from various jurisdictions — including South Korea, Singapore, and the United States — are taking legal action against Kwon. On 23 March 2023, Kwon was arrested in Montenegro, while attempting to travel to Dubai using falsified documents. Following his arrest, he was charged by a US federal grand jury of eight counts, including securities fraud, commodities fraud, wire fraud, and conspiracy.
