South Korea charges CATFI memecoin operators in first DEX rug-pull case

South Korean prosecutors have charged a group linked to the Solana-based memecoin CATFI, also known as Catpie, in what local outlets described as the country’s first prosecution tied to a rug pull on a decentralized exchange. The Seoul Southern District Prosecutors’ Office, through its Virtual Asset Crime Joint Investigation Division, arrested the core suspects. The lead figure, identified by the surname Park, allegedly posed online as “Eth Father” and promoted CATFI as an independent third-party project before the scheme unfolded, according to Digital Asset Works.

Investigators say the defendants used social media to hype CATFI, driving the token’s price up more than 1,000-fold within about 26 hours. They then sold their holdings for roughly 400 million won in illicit profits, while the rug pull inflicted about 900 million won ($599,000) in losses on at least 256 investors. The case represents a rare legal action in South Korea against memecoin price manipulation under the Virtual Asset User Protection Act.

Prosecutors noted that rug pulls are deceptive exit scams in which project creators cultivate investor interest, only to abandon the project and siphon away funds. Cointelegraph reached out to the Supreme Prosecutors’ Office for comment but had not received a response by publication as the investigation unfolds.

The case adds to the ongoing scrutiny of domestic crypto markets and comes as South Korea’s crypto trading activity has cooled. Digital Asset Works highlighted a broader market backdrop in which won-based exchanges have seen trading volumes shrink relative to the KOSPI stock market, underscoring heightened regulatory attention to market manipulation and investor protection.

Key takeaways

.li>First confirmed arrest in a memecoin rug pull under South Korea’s Virtual Asset User Protection Act, tied to the CATFI/Catpie case.

• CATFI surged over 1,000 times in price within 26 hours before promoters sold approximately 400 million won in illegal profits; roughly 900 million won in losses reported across at least 256 investors.


• The token’s market profile collapsed from an all-time peak to a dramatic 99% decline, with on-chain data showing 1,512 holders remaining as of now and the largest holder controlling about 18% of supply.


• Domestic market context features a notable drop in won-based trading volume, highlighting regulatory and market headwinds for memecoins and similar high-risk assets.


• Related incidents this year underscore ongoing risk in meme tokens, including high-profile rug pulls tied to social media-driven hype and influencer-linked projects.

CATFI’s rise and fall in context

CATFI briefly reached an all-time market capitalization of about $8.99 million in February 2025, but the subsequent rug pull and exit scam knocked the token back into a lurching decline. Data from Pump.fun indicates that, despite the collapse, a significant portion of investors—about 1,512 holders—still appear to be holding CATFI in hopes of recovery. The largest known address, a wallet labeled “5Q54,” reportedly held around 18% of the token’s supply at the time data was compiled. The project’s former promoter’s X (Twitter) account has since been deleted, reflecting the erasure of public-facing outreach tied to the campaign.

The legal action signals that authorities are increasingly willing to pursue coordinated manipulation cases in the memecoin space. Rug pulls—where developers promote a token to attract funds and then abruptly abandon the project—have long threatened retail investors, particularly in communities built around social media-driven hype. The CATFI case is positioned as a test of South Korea’s enforcement under evolving crypto consumer protection standards.

However, the CATFI saga is not isolated. In May, Cointelegraph reported on another Solana memecoin linked to Keith Gill’s Roaring Kitty persona that experienced a separate rug pull, with the anonymous developer cashing out about $729,000 while investors saw steep losses. The episode, alongside the CATFI case, underscores the volatility and risk profile of meme-oriented assets even as markets evolve and regulators scrutinize suspicious activity more closely.

For individual traders, the CATFI episode illustrates how quickly momentum-based tokens can flip from rapid gains to devastating losses. One trader reportedly saw a loss approaching six figures in a short period during a recent memecoin event, highlighting the real-world stakes involved in these crowded, speculative spaces.

Regulatory backdrop and market dynamics in South Korea

The CATFI case arrives amid a downturn in domestic digital asset trading activity. Digital Asset Works’ coverage notes that won-based exchanges have seen shrinking volumes, with overall activity in the Korean market growing more cautious in the face of regulatory scrutiny and increased risk awareness among investors. The development underscores a broader tightening environment where authorities emphasize consumer protection, anti-manipulation measures, and accountability for project teams behind high-risk tokens.

South Korea’s enforcement trajectory—with the CATFI investigation marking a potential precedent—could influence how future memecoin launches are treated under existing laws. While the case does not conclusively determine the long-term legality of memecoins themselves, it demonstrates that orchestrated price manipulation and exit schemes are increasingly susceptible to legal repercussions, potentially reshaping project funding dynamics and investor diligence in the domestic market.

What comes next for CATFI and the market

As prosecutors proceed with the case, observers will be watching how charges unfold, whether additional arrests follow, and what implications this may have for the broader memecoin ecosystem in South Korea. The outcome could influence how exchanges assess listing risk, how influencers disclose promotional activity, and how investors evaluate exit risk in hype-driven tokens. In the near term, CATFI’s holders face a challenging landscape: questions about potential refunds, recovery pathways for defrauded investors, and the sustainability of token liquidity in the wake of the rug pull remain unresolved.

Readers should watch for further updates from South Korean authorities as the investigation progresses, along with any court rulings that could redefine enforcement norms for memecoins and similar schemes. The CATFI case may serve as a bellwether for how regulatory regimes balance innovation and investor protection in a fast-moving, social-media-driven segment of the crypto market.
