Details of the CATFI scheme on Solana
South Korean prosecutors arrested and charged a group of individuals connected to the Solana-based CATFI memecoin following an alleged rug pull executed on a decentralised exchange. The operation is the first formal criminal case in the country targeting a memecoin scam that occurred entirely within a decentralised trading environment. Authorities state that the scheme drew in hundreds of retail investors who suffered substantial losses after the token experienced a sharp price increase followed by a liquidity drain and collapse.
The CATFI token launched on Solana and traded mainly through decentralised platforms including Pump.fun. Investigators claim the operators promoted the token aggressively as a high-potential memecoin to attract early buyers. One key promoter reportedly operated under the alias Eth Father and used that identity across social channels to build trust and encourage participation. Once trading volume and liquidity grew, the operators allegedly engaged in coordinated trading activity such as wallet splitting and wash trading to create the appearance of organic demand.
Price surge and subsequent collapse
At its peak the CATFI token reportedly increased more than one thousand times in value within a short period. That rapid rise ended abruptly when liquidity was withdrawn and large holdings were sold, producing a price collapse consistent with a classic rug pull. Prosecutors estimate that around 256 investors were directly affected, with total losses reaching approximately 900 million won or about 650,000 US dollars. Investigators also identified roughly 400 million won, or 260,000 US dollars, in illicit profits linked to the scheme.
Arrests, charges and legal framework
The Seoul Southern District Prosecutors Office Virtual Asset Crime unit led the investigation. Two primary suspects were arrested and five individuals in total were charged. Additional suspects remain under investigation for allegedly assisting key figures in evading arrest. The case is being prosecuted under South Korea Virtual Asset User Protection Act, a recently introduced law aimed at addressing fraud and manipulation in digital asset markets. Authorities continue to trace wallet activity, promotional networks and liquidity movements connected to the token launch.

Significance for South Korean crypto enforcement
This prosecution represents the first known instance in South Korea where criminal charges have been pursued specifically for a DEX-based memecoin rug pull. Earlier enforcement actions focused mainly on centralised exchanges or structured investment fraud, but this case extends scrutiny directly into decentralised trading environments. Prosecutors have made clear that the use of decentralised platforms does not shield individuals from criminal responsibility. By applying the Virtual Asset User Protection Act to on-chain activity, authorities signal that token creators and promoters can be held accountable even without a centralised intermediary.
The CATFI case also illustrates how quickly memecoin ecosystems can amplify both gains and losses. The reported one-thousand-times surge attracted many retail traders, yet the subsequent collapse erased those gains almost immediately after liquidity was removed. With 256 confirmed victims and losses reaching hundreds of millions of won, regulators are treating the incident as coordinated financial fraud involving token manipulation and misleading promotion rather than a simple market failure. The outcome is expected to influence how future memecoin projects are launched and monitored in South Korea.
