According to BlockBeats, Tesla China released the 2026.14.13 in-vehicle software update on July 31, covering Model 3, Model Y, Model S, and Model X models.

The rollout began on July 31, 2026, with one of the software updates primarily upgrading "Doubao Big Model": an intelligent voice assistant that not only provides real-time information but also engages in natural and fluent conversations; it supports multiple premium voice options and can be paired with personalized characters such as "Know-It-All," "Music Lover," and "Storyteller." This feature requires activation of premium in-vehicle entertainment services.

According to BlockBeats, on July 31, Bitget data showed that the Hang Seng Tech Index rose more than 1% intraday, after falling as much as 0.7% previously. The Hang Seng Index was about to turn positive intraday, after falling as much as 1% previously.

BlockBeats reports that on July 31, Canadian hardware wallet manufacturer Coinkite issued a security warning, advising users of Coldcard Mk3 wallets who generated mnemonic phrases in firmware versions 4.0.1 to 5.0.3 to migrate their assets as soon as possible. The company stated that preliminary analysis shows wallets using BIP-39 passphrases have a lower risk, and Mk4, Q, and Mk5 devices are unaffected. The investigation is ongoing.

Meanwhile, security researchers are investigating an unusual transfer involving 594.48 BTC (approximately $38.3 million). AnchorWatch CEO Rob Hamilton stated that the attacker transferred 1324 UTXOs in 500 transactions over three blocks, speculating that the problem may have stemmed from insufficient random number entropy during wallet generation.

Wizardsardine CEO Kevin Loaec believes the vulnerability may be related to a low-entropy random number generator in a software library, security chip, or specific device batch or firmware version. Attackers could potentially use AI-generated scripts to brute-force the affected wallets. Currently, there is no conclusive evidence linking this fund transfer directly to the Coldcard Mk3 vulnerability.

According to BlockBeats, on July 31, the Federal Reserve kept interest rates unchanged at 3.5%-3.75% at its July meeting, and the large-scale hedging positions previously built around the rate hike were quickly unwound.

Data shows that in August, open interest in federal funds futures briefly exceeded 1 million contracts for the first time in history, involving approximately $5 trillion in notional principal. After the decision was announced, CME data showed that open interest in the contract decreased by approximately 140,000 contracts. The previously continuously increasing net short positions of leveraged funds were reversed, and the price of federal funds futures in August rose rapidly, turning short positions betting on interest rate hikes into losses.

The market had previously raised the probability of a July rate hike to nearly 50%, but trading quickly cooled down as the new Federal Reserve Chairman Kevin Warsh did not signal a rate hike.
