Coinbase suffered an MEV bot attack due to its interaction with the 0x exchange, resulting in an estimated loss of $300,000.
2025/08/14 12:20
PANews reported on August 14th that Venn Network security researcher deeberiroz reported, according to The Block, that Coinbase lost approximately $300,000 due to a misconfigured interaction between Coinbase and the 0x project's "switcher" contract. In response, Coinbase Chief Security Officer Philip Martin stated that no customer funds were affected and that this was an isolated incident.
The 0x project provides an "exchanger," a contract designed specifically for performing swaps. This contract is permissionless and can be called by anyone to perform arbitrary operations, regardless of ownership restrictions. Because this contract is permissionless, the bot appears to have called the exchanger contract to perform a transfer, transferring approved tokens from the Coinbase wallet to their own addresses.

Genius Group’s $1B Lawsuits Could Trigger 5,000 BTC Buying Spree
Genius Group, a Nasdaq-listed AI-driven education company, has approved a plan to split potential winnings from two major lawsuits between its shareholders and Bitcoin treasury. The company says it could recover more than $1 billion in damages from the combined cases. In a press release on Thursday, the Singapore-based company announced that its board of directors has approved a distribution plan for any net damages it recovers. According to the statement, 50% of any funds won in court would be paid out to shareholders as a special dividend, while the remaining 50% would be used to purchase Bitcoin. CEO Roger Hamilton said the decision was made to ensure that any court victories benefit shareholders directly. “The Company has two legal cases, one filed and one pending, in which we are seeking combined damages of over $1 billion,” he said. Genius Group Targets $1B in Damages—50% to Shareholders, 50% to Bitcoin The company’s first lawsuit, already filed in the U.S. District Court for the Southern District of Florida, seeks over $750 million in damages under the Racketeer Influenced and Corrupt Organizations (RICO) Act. The suit names four individuals, including former SEC Chairman John Clayton, and alleges misconduct that caused financial harm to Genius Group. A second lawsuit is still pending and centers on allegations of naked short selling and market manipulation. The firm says preliminary analysis of its 2023 trading data shows damages between $251 million and $262 million. Its legal team, led by attorney Wes Christian, is currently updating the claim with more recent trading records, and expects the damage estimate to increase significantly before filing. “As both lawsuits are being pursued by the Company to recover damages caused by third parties directly to our shareholders, the Board believes that 100% of any proceeds from the successful outcome of these cases should be directly distributed or reinvested for the benefit of shareholders.” Roger said. 50% of legal wins go to $GNS shareholders as special dividend, 50% to $BTC Bitcoin Treasury. No guarantee how much we recover, but in a utopian alternate universe where justice prevails $1B damages = $7/share dividend + 5,000 $BTC . In a Saylor double alternate universe where… pic.twitter.com/x3sNg4UaoK — Roger James Hamilton (@rogerhamilton) June 26, 2025 Genius Group said the upcoming short selling lawsuit is currently in its final review and will include revised damage estimates based on continued tracking of share trading activity. There’s no timeline yet for when either case may conclude, and the company cautioned that there’s no certainty around the final outcome or the amount of damages it may recover. Still, Genius Group has laid out a clear post-trial roadmap. Once any net damages are collected, after deducting legal fees, recovery costs, and taxes, the funds will be split. Shareholders would receive a dividend, while the company would use the other half to add to its Bitcoin holdings. If successful, the strategy could set the stage for one of the largest corporate Bitcoin purchases linked directly to litigation proceeds. The company did not disclose how much Bitcoin it currently holds but has previously described itself as a “Bitcoin-first” organization . Genius Group is listed on the NYSE American under the ticker GNS. Any payouts or purchases will follow regulations from the SEC, the NYSE, and Singaporean authorities. Court Drama Eases as Genius Group Resumes Bitcoin Buying Spree Post Legal Freeze Following a turbulent legal standoff that saw Genius Group barred from raising funds and forced to offload part of its Bitcoin treasury, the education and AI-focused firm is now back on the offensive. On April 3, a New York court temporarily prohibited Genius Group from selling shares or using investor funds to purchase Bitcoin, citing ongoing lawsuits linked to its scrapped deal with Fatbrain AI (LZGI). 🚨 A New York court restricts Genius Group from raising funds or buying Bitcoin, forcing the company to sell part of its Bitcoin treasury amid legal battles and financial strain. #Crypto #Regulation https://t.co/Evr2bOXIQ7 — Cryptonews.com (@cryptonews) April 3, 2025 Allegations of fraud involving executives Michael Moe and Peter Ritz escalated into a full-blown legal freeze. The court injunction, backed by an SEC complaint, also halted the company’s $150 million at-the-market share offering. Forced to stay afloat, Genius sold down its BTC holdings from 440 BTC to 430 BTC as operations came under pressure. However, a U.S. Court of Appeals ruling in May reversed the freeze , clearing the way for Genius to re-enter the market. On May 22, the company confirmed a new Bitcoin purchase of 24.5 BTC, boosting its treasury to 85.5 BTC at an average cost of $99,700 per coin, a total of $8.5 million invested. 🔓 @GeniusGroupAI has resumed Bitcoin accumulation after a U.S. court lifted its treasury ban, boosting holdings by 40% to 85.5 BTC and reaffirming its 1,000 BTC target. #Bitcoin #GeniusGroup https://t.co/fOrMLXv12D — Cryptonews.com (@cryptonews) May 23, 2025 That marks a 40% increase since the freeze was lifted, positioning Genius Group back in the ranks of corporate Bitcoin accumulators.

South Korea Takes Another Step Toward Crypto Reform Amid Talk of Regulatory Shake-up
South Korea’s government is set to fast-track pro-business crypto reforms, including stablecoin regulations. The South Korean newspaper Metro Seoul reported that the Presidential Committee on State Affairs announced its plans at a public briefing on August 13. South Korea Crypto Reform Taking Shape The committee spoke of a five-year plan for state administration, naming 123 state affairs-related tasks. Among these tasks named were “the construction of a digital asset ecosystem” and “developing the domestic cryptoasset market.” Both were identified as “key national tasks” for the administration, which took office in early June this year following the election of President Lee Jae-myung. President Lee Jae Myung on Wednesday laid out a sweeping five-year policy agenda, detailing 123 national tasks ranging from constitutional reform to industrial growth and market fairness. https://t.co/52cb7gzOvi — The Korea JoongAng Daily (@JoongAngDaily) August 13, 2025 Lee has spoken repeatedly about his intention to build up the domestic crypto sector, with deregulation and stablecoin regulation high on his agenda. The President appears keen to let domestic firms issue won-pegged stablecoins . Leading banks and IT companies have reacted by registering scores of stablecoin-related trademarks . Others are hurriedly rolling out crypto-related business plans, aware that this may allow non-financial firms to develop advanced payment platforms. However, one of President Lee’s key campaign pledges was left off the five-year plan, namely the dissolution of the Financial Services Commission (FSC). The FSC is the nation’s top financial regulator. Its Financial Intelligence Unit (FIU) polices the country’s crypto exchanges , issuing operating permits and conducting periodic on-site inspections. It also enforces anti-money laundering and terrorist financing protocols at the trading platforms. The Government Complex Building in Seoul, South Korea. (Source: Seoul Institute [CC BY 4.0]) FSC: Vociferous Critic No More? In previous years, the FSC has been a vociferous critic of the crypto sector. But in recent years, as governments have relaxed their hardline stance to the industry, it has spoken in favor of reform. Under the proposal, FSC’s supervisory duties were to transfer to the Financial Supervisory Service. The FSC’s policy-related tasks were due to transfer to the Ministry of Strategy and Finance. But Lee’s plan to scrap the FSC proved controversial, even among senior ministers. While his offices have yet to confirm that the President has shelved the policy, the five-year plan appeared to suggest the proposal may have moved to the back burner. There was no mention of the regulatory reorganization move on the plan. And seven of the 123 tasks were assigned to the FSC. The newspaper added that crypto reforms are a “key focus” for both the government and the National Assembly this year. As such, reforms are “expected to gain momentum” in the weeks ahead, Metro Seoul wrote. ‘Time to Play Catch-up’ Political leaders are concerned that South Korea is being left behind. They note that over the past two years, the global crypto market has expanded by about 262%. While crypto investment has spiked in the US, the European Union, and Japan, driven by institutionalization drives, the same cannot be said for Seoul. The outlet wrote: “Delayed institutional reforms and a lack of legislation in South Korea have left the domestic cryptoasset market significantly lagging in terms of competitiveness.” South Korea says President Lee Jae Myung to visit Japan this month https://t.co/PmtmRcPibF — Nikkei Asia (@NikkeiAsia) August 13, 2025 The FSC has prioritized its plan to allow corporations to buy and sell crypto. It also wants to tak a “more relaxed approach” to regulations. The regulator has previously spoken of its intention to roll out crypto-related regulations before the end of this year. However, skeptics say that a final decision on the fate of the FSC is yet to be taken. Talks to abolish the regulator “may resume in the future,” the newspaper explained. Unnamed financial sector officials opined that the debate over the reorganization of the financial regulators would “continue until the end of the year.” Earlier this month, the Seoul district of Gangnam announced it had recouped $144,057 in unpaid taxes in the first half of this year by seizing coins from tax evaders .
