The main suspect, surnamed Park, allegedly operated a social media account under the alias 'Eth Father' while simultaneously managing the CATFI project's official promotional channels — falsely presenting himself as an independent third-party influencer with no project affiliation. Alleged tactics documented by prosecutors included: artificial inflation of social media follower counts; publication of false positive announcements designed to generate FOMO among retail investors; distribution of token holdings across multiple wallets to conceal the degree of insider supply control; and circular (wash) trading across those wallets to simulate organic market demand. According to reporting by BanklessTimes and BeInCrypto, the group deployed an initial capital of approximately 10 million Korean won (~$6,700) and extracted approximately 400 million won (~$260,000) in alleged illegal proceeds before withdrawing liquidity. The token's price increased 1,001-fold within 26 hours of issuance before collapsing.","heading":"Alleged Fraud Scheme and Market Manipulation","severity":"critical","sources":[{"credibility":2,"name":"South Korea Launches First-Ever Criminal Case Over DeFi DEX Rug Pull — BanklessTimes","type":"news_article","url":"https://www.banklesstimes.com/articles/2026/05/27/south-korea-launches-first-ever-criminal-case-over-defi-dex-rug-pull/"},{"credibility":2,"name":"South Korea Makes First Arrest and Prosecution in Meme Coin Rug Pull Case — BeInCrypto","type":"news_article","url":"https://beincrypto.com/solana-meme-coin-south-korea-dex-indictment/"},{"credibility":2,"name":"South Korea Files First DEX Fraud Case After CATFI Rug Pull Scam — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/05/27/south-korea-files-first-dex-fraud-case-after-catfi-rug-pull-scam/"}]},{"content":"Investigators report that approximately 6,000 individuals purchased CATFI tokens during the promotion period. Of these, 256 investors formally reported losses, with combined documented losses of approximately 900 million Korean won, equivalent to roughly $585,000–$650,000 USD depending on exchange rate at time of reporting. The discrepancy between the total buyer count (6,000) and the formal victim count (256) may reflect the difficulty of documenting on-chain losses or differing loss thresholds for formal reporting.

The VAUPA took effect on July 19, 2024, and was previously applied in January 2025 in a separate case involving the centralized exchange Bithumb and alleged manipulation of the ACE token — making the CATFI prosecution reportedly only the second VAUPA case overall, and the first extending to decentralized infrastructure. Prior to the VAUPA, decentralized exchanges were described by prosecutors as existing in a 'regulatory blind spot.' Investigators demonstrated that the off-ramp from pseudonymous on-chain activity to fiat currency exchanges provided identifiable choke points, and that circular trading patterns across multiple wallets could be reconstructed and attributed to specific individuals through chain analysis. This precedent is expected to inform future South Korean enforcement actions targeting DEX-based token manipulation.","heading":"Regulatory and Legal Significance","severity":"high","sources":[{"credibility":2,"name":"South Korea Makes First DEX Rug Pull Arrests in Solana CATFI Case — CoinJournal","type":"news_article","url":"https://coinjournal.net/news/south-korea-makes-first-dex-rug-pull-arrests-in-solana-catfi-case/"},{"credibility":2,"name":"South Korea Files First DEX Fraud Case After CATFI Rug Pull Scam — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/05/27/south-korea-files-first-dex-fraud-case-after-catfi-rug-pull-scam/"},{"credibility":2,"name":"South Korea Brings First DEX Rug Pull Arrest In CATFI Meme Coin Case — CryptoAdventure","type":"news_article","url":"https://cryptoadventure.com/south-korea-brings-first-dex-rug-pull-arrest-in-catfi-meme-coin-case/"}]},{"content":"The Seoul prosecutors' Joint Investigation Department for Virtual Asset Crimes employed both on-chain analysis and social media evidence to build the case. Investigators traced wallet activity to identify circular trading patterns — multiple wallets controlled by the same operators conducting trades among themselves — and linked those wallet addresses to the suspects' social media accounts and real-world identities. The conversion of token proceeds to fiat currency through centralized exchanges, which operate under know-your-customer (KYC) requirements, provided the primary identification vector for suspects who had previously operated pseudonymously on the DEX. This methodology — combining on-chain forensics with fiat off-ramp records — is consistent with techniques used in other international cryptocurrency fraud prosecutions and is reported to have been sufficient to establish the evidentiary chain linking Park's 'Eth Father' online persona to the CATFI project's wallet infrastructure.","heading":"Investigation Methodology","severity":"medium","sources":[{"credibility":2,"name":"South Korea Launches First-Ever Criminal Case Over DeFi DEX Rug Pull — BanklessTimes","type":"news_article","url":"https://www.banklesstimes.com/articles/2026/05/27/south-korea-launches-first-ever-criminal-case-over-defi-dex-rug-pull/"},{"credibility":2,"name":"South Korea Makes First DEX Rug Pull Arrest in Catfi Case — Yahoo Finance / original reporting","type":"news_article","url":"https://finance.yahoo.com/markets/crypto/articles/south-korea-makes-first-dex-122540420.html"}]},{"content":"CATFI was launched on Pump.fun, a permissionless Solana-based token launchpad that allows any user to create and deploy a token with minimal friction.
