Ostium released an update on the attack incident. Its liquidity provider fund was attacked on July 15, resulting in a loss of 23,752,746 USDC. Preliminary investigations indicate that the attacker compromised the off-chain infrastructure that provides price data to the protocol and submitted disguised illegal price reports, extracting artificially generated profits from the fund by quickly opening and closing multiple large positions.Ostium stated that traders' collateral is stored in independently isolated smart contracts and was not affected by this incident, with all trading positions remaining open. The team paused trading and froze all trading contracts within 60 minutes after the first attack transaction occurred. Currently, Ostium is collaborating with Mandiant, zeroShadow, Collisionless, SEAL 911, and law enforcement agencies, coordinating with trading platforms, bridging contracts, and stablecoin issuers to advance the investigation. The engineering team is focused on repairing and strengthening the relevant infrastructure to support the secure resumption of trading.Ostium indicated that it will notify at least 24 hours in advance before unfreezing the trading contracts. After trading resumes, existing positions will be marked at the price at the time of reopening, unaffected by price fluctuations during the pause. Addressing the affected liquidity providers and securely resuming trading remains the current top priority.

Coinbase launched a high-yield USDC lending tier with an annualized rate of about 7.02% a few days after the 7% yield campaign on Robinhood Earn, which is approximately double its standard tier of 3.63%. Both are routed through the decentralized lending protocol Morpho, which has a total value locked (TVL) of $7.11 billion, curated by Steakhouse Financial. However, according to analysis from the account Pink Brains, there are essential differences in the yield structures.Robinhood's 7% is composed of borrower interest, USDG treasury reserve earnings, and subsidies distributed through Merkl. The subsidies cover the gap between organic earnings and the 7% target, with organic earnings actually around 3% in the middle range, meaning about half is from subsidies. Coinbase, on the other hand, circulates funds by lending Ethena USDe to the marginal funding rate of perpetual contracts, further layering MORPHO token rewards, with no fixed cap but also no guaranteed minimum.Pink Brains pointed out that Coinbase's blended yield including rewards has dropped to 4.44%. Robinhood's subsidy commitment lasts for one year, betting on organic earnings rising with new lending demand; Coinbase's activity is unofficially estimated to last until mid-September.

According to the Financial Times, based on the latest publicly available court documents, the stablecoin issuer Circle had banned the crypto fund Heka Funds, supported by Tether, at the end of 2023 due to suspicions that it was manipulating the market through large-scale arbitrage operations and helping Tether expand its market share. The documents show that during the Silicon Valley Bank (SVB) crisis in 2023, USDC briefly fell below the $1 peg. Heka continuously bought discounted USDC in large quantities and redeemed it for cash from Circle. Circle believed that Heka's redemption scale far exceeded that of other market participants and suspected that the related funds ultimately flowed to Tether to help expand its USDT market size.Arbitration documents also revealed that Tether had invested about $800 million in Heka, accounting for about 75% of the fund's assets, and waived the stablecoin minting fees. The arbitrator found that Heka did not truthfully disclose its supportive relationship with Tether and was aware that the related information would raise concerns for Circle. In 2024, Heka initiated arbitration due to its account being frozen, claiming approximately $49 million in lost profits. In February of this year, the arbitrator dismissed all of Heka's claims, determining that it had engaged in malicious behavior and ordered it to pay Circle about $166,000 in attorney and expert fees. Heka denied any market manipulation and stated that it had never been subject to regulatory investigation; Circle declined to comment, and Tether did not respond to media requests for comment.

According to BLOCKMEDIA, the South Korean police are investigating a case of political interference in the competition of the cryptocurrency market. A former assistant to independent lawmaker Kim Byung-ki is accused of pressuring the Financial Supervisory Service (FSS) in February last year to force Upbit to terminate its fee waiver activities for $USDC and $USDT, in order to alleviate the financial pressure on its competitor Bithumb, which was suffering due to a zero-fee promotion.The suspicion arises from the fact that the assistant obtained an informal advisory position at Bithumb months after the interference, while at the same time, the lawmaker's son was also hired by the exchange as an intern. Bithumb denies any knowledge of political interference and insists that the fee adjustments were independent business decisions.
