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 Polymarket Switches on Instant Bitcoin Lightning Deposits, Cutting 60-Minute Waits to Under a Second appeared on BitcoinEthereumNews.com.
Key Takeaways Polymarket now credits bitcoin Lightning deposits in under 1 second via Spark, versus 10–60 minutes onchain.

The post Polymarket and CEO Shayne Coplan Sued Over Strategy Bitcoin Sale appeared on BitcoinEthereumNews.com.
Polymarket sued after resolving a Strategy Bitcoin market as “No” despite an SEC filing showing a BTC sale. Plaintiffs say Polymarket should have resolved “Yes” after Strategy’s SEC filing disclosed a 32 BTC sale. This signals ongoing tensions in prediction market resolution criteria as volumes and scrutiny surges. Polymarket and Chief Executive Officer (CEO) Shayne Coplan are facing a lawsuit over the settlement of a prediction market on whether Strategy (formerly MicroStrategy) sold Bitcoin (BTC) before May 31, 2026.

Polymarket Faces Lawsuit Over Disputed Strategy BTC Sale Settlement On July 3, 2026, two Polymarket traders, William Wood and Thomas Bush, filed a lawsuit in the New York Supreme Court against Polymarket, alleging the platfo
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.

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
