South Korea Makes First DEX Rug Pull Arrest in Catfi Case

South Korea, Seoul Southern District Prosecutors’ Office has arrested and indicted operators behind Catfi. This is the country’s first-ever rug pull prosecution tied to a decentralized exchange.

The case, brought under the Virtual Asset User Protection Act, charges the group with market manipulation after 256 investors lost 900 million won($586,000), when liquidity was drained following an artificial price surge.

The scheme began on Pump.fun in early 2025, where the main suspect, identified by the surname Park, operating online as the influencer ‘Eth Father,’ created Catfi before listing it on a decentralized exchange. Park allegedly posed as an unrelated third party to recommend purchases, inflated follower counts, managed project social accounts, and spread tokens across multiple wallets while using circular trading to obscure issuer control.

Catfi’s price surged 1,001-fold within 26 hours of issuance, with 6,000 investors buying in before the liquidity vanished. The group used approximately 10 million won in criminal funds and walked away with 400 million won, or $260,000, in proceeds.

South Korea Catfi Arrest and DeFi Regulation

Until this Catfi case, South Korea virtual asset enforcement had concentrated almost entirely on centralized exchanges. DEX fraud occupied a legally murky space: non-custodial design, pseudonymous wallet operators, and the absence of a regulated intermediary made it structurally difficult to assign criminal liability under frameworks built for traditional finance or even CEX abuse.

The Virtual Asset User Protection Act, which took effect in July 2024, gave prosecutors a statutory basis, covering “the use of fraudulent means, plans, or techniques” and false statements about material facts in digital asset trading, regardless of venue.

The Catfi prosecution is only the second known matter under the Act, following the January 2025 ACE token manipulation case on Bithumb, but the first to reach into a DEX environment.

Seoul Southern District prosecutors framed the enforcement mandate explicitly, stating the office would “resolutely deal with acts that disrupt the digital asset market and undermine public trust.”

DeFi regulation in South Korea has now moved from exchange oversight to on-chain conduct, and operators who assumed decentralization meant immunity are reading that statement very carefully right now.

The Tracing Mechanism

The Catfi case illustrates the investigative template that makes on-chain forensics increasingly dangerous for rug pull operators. Prosecutors identified circular trading patterns, coordinated wash trades across wallets controlled by the issuing group, which created artificial volume and masked insider ownership concentration.

From there, the off-ramp is typically the exposure point: converting criminal proceeds into fiat or stablecoins requires touching a centralized exchange with KYC obligations, and that intersection is where pseudonymous operators become identifiable individuals.

South Korea’s enforcement bodies have developed this pattern across prior cases; the 149-arrest USDT laundering ring announced earlier this year demonstrated that prosecutors can map complex multi-wallet schemes at scale. The Catfi group’s use of approximately 10 million won in traceable criminal funds suggests the on-chain trail was coherent enough to anchor the indictment.

Two suspects were arrested and indicted for market manipulation; one was indicted without detention; two others were charged for helping the main suspect flee. Similar reconstruction methods were visible in the Squid protocol exploit, where on-chain tracing helped identify the flow of drained funds across multiple hops.
