The post Polymarket’s Frontend Attack Shows Why Real-Time Platforms Need Better User-Side Security appeared on BitcoinEthereumNews.com. Polymarket’s latest security incident did not begin with a broken smart contract. The prediction market platform said a compromised third-party vendor injected malicious code into its frontend for some users, exposing them to a phishing attack and forcing the company to promise full reimbursement. For crypto users, that detail matters. A platform can be sound on-chain and still become dangerous at the screen where a wallet signs, clicks, or confirms. The attack was not only about code According to TechRadar, Polymarket said the affected vendor had been contained and the compromised dependency removed after the attack was discovered. Blockchain monitoring firm PeckShield estimated that roughly $3 million in crypto was stolen from around 11 users, while Polymarket said it was contacting impacted users and refunding them in full. That sequence is familiar

The post BONK Treasury Vote: DAO Governance Risk Returns appeared on BitcoinEthereumNews.com. So here we are again. Not a smart contract exploit in the classic sense, but a rules-as-written treasury drain that sailed through governance because nobody showed up. If you hold meme tokens with DAOs attached to them, this is the wake-up call. The BONK saga isn’t just a one-off. It shows how cheap it can be to buy enough votes, meet quorum, and walk out with a treasury haul if a community is disengaged. The fix isn’t magical. It’s mostly better parameters, better process, and people actually voting. Aspect What to Know What happened An anonymous wallet filed a proposal to move roughly 4.426 trillion BONK from the BonkDAO treasury to their own wallet, and it passed with minimal turnout, triggering an automatic transfer (CoinCentral). How it was executed The attacker reportedly spent about $4.4 million buying roughly 882.285 billion BONK on centralized exchanges to

The post ‘Major loss’: New York Court rejects Kalshi’s injunction request appeared on BitcoinEthereumNews.com. Prediction market platform Kalshi has suffered a legal loss in New York. According to a court filing on the 7th of July, the firm was denied a preliminary injunction by Judge Analisa Torres of the Southern District of New York. Judge Torres maintained that gambling falls under the purview of local state oversight. The scope of laws regulating gambling and lotteries is clearly a matter of predominantly state concern. Additionally, Judge Torres clarified that federal law, the Commodity Exchange Act, does not preempt state gambling laws. Courts apply a presumption against preemption with respect to areas where states have historically exercised their police powers. Source: Court Listener She explained that such a presumption arises only when Congress legislates in a field traditionally governed by the states. In other words, federal authority applies only where Congress has
