Ethereum Foundation Warns of Potential Cryptocurrency Wallet Disruptions

Abstract

The Ethereum Foundation (EF) has warned of potential disruptions to crypto wallets and related software due to the upcoming "Glamsterdam" network upgrade, which will change Ethereum's gas fee model. In an August 17 announcement, developers cautioned that wallets, indexers, and fee estimation tools, particularly those with hardcoded maximum gas limits, risk breaking and will require updates. The issue stems from EIP-8037, introducing a new "state-gas" dimension for operations that create new state, such as sending ETH to a new address. While a standard transfer to an existing address will remain 21,000 gas, sending to a new address will incur an additional cost. Developers urged a review of smart contracts and code that assume 21,000 gas covers any ETH transfer or that calculate fees based solely on gas quantity. Developers are advised to test their systems on the public testnet "Plataberget," launched on August 13, 2026, where the Glamsterdam activation is scheduled for August 20. A one-month feedback and client software update phase will precede testing on the Sepolia and Holesky testnets before the mainnet launch.

The upcoming Glamsterdam upgrade will change the gas model, and some software risks malfunctioning. The Ethereum Foundation (EF) team warned about this on August 17.

According to the developers, wallets, indexers, and fee estimation tools could be at risk. Programmers were advised to test their systems on the public testnet Plataberget.

The EF emphasized tools with a "hard-coded maximum gas limit": such solutions, they stated, will stop working and require an update.

The issue is related to EIP-8037. The proposal adds a separate state-gas dimension for operations that create new state. A regular $ETH transfer to an existing address will keep its cost at 21,000 units, but sending coins to a new address will incur an additional charge.

Developers urged a review of smart contracts that assume the logic that 21,000 units covers any $ETH transfer, as well as code that calculates fees based solely on gas quantity.

According to Forkcast, Plataberget was launched on August 13, 2026. The activation of Glamsterdam on this testnet is scheduled for August 20. Before the mainnet launch, there will be a feedback and client software update phase, estimated to last one month, followed by testing on Sepolia and Hoodi.

Recall that in August, Buterin named quantum resistance and AI as priorities for Ethereum.

Venice Token Price Forecast: VVV Eyes $15 as Revenue Surpasses $100 Million

Venice Token (VVV) attracts attention after a sharp price rise, trading near $13.71 with a 12.29% daily gain. The rally follows co-founder Eric Voorhees reporting the platform has surpassed $100 million in annualized revenue, reaching profitability in Q1. Venice AI boasts 3.5 million users, 1.7 million daily API calls, and a token model that burns VVV for API credits, with 33.7 million tokens (42% of supply) already burned. Technically, VVV shows a bullish short-term reversal on the 4-hour chart, approaching key Fibonacci resistance at $13.50. A break above could target $14.50 and the psychological $15 level. However, momentum indicators like Stochastic RSI suggest overbought conditions, risking a pullback to support zones at $13.18-$13.00 or $12.70-$12.41. A key divergence is noted: despite the price recovery, open interest in derivatives remains low at ~$55.72 million, well below its $140 million peak, suggesting the current move is driven more by spot demand than leveraged speculation. Persistent spot net outflows also present a cautionary signal. The token's short-term direction hinges on holding above $13.50, with improved platform fundamentals acting as a potential catalyst.

Domestic RF Filters, Finally Starting to Compete?

China's domestic filter industry, particularly in the challenging BAW (Bulk Acoustic Wave) segment, has reached a significant inflection point, moving from solving the "availability" problem to entering a phase of commercial competition and scale. The market is attractive, with the global mobile terminal RF filter market projected to reach $9.2 billion in 2025, and BAW filters showing strong growth. However, the sector is historically dominated by giants like Broadcom and Qorvo, protected by deep patent walls, as evidenced by lawsuits that have bankrupted competitors like Akoustis. Previously, high-frequency BAW filter production in China was nearly zero. Now, domestic players like Nous Micro, Wuhan Memsensing, Hansky, and others are forming a genuine industrial cluster, achieving mass production and shipping hundreds of millions of chips to clients. Different business models are emerging, including IDM and fab-lite approaches through partnerships with foundries like Sai Microelectronics and Runxin Sensing. A key signal of this new competitive phase is a patent lawsuit filed by Nous Micro against Wuhan Memsensing in June 2025, alleging infringement of a core BAW resonator patent. This conflict, rather than mere internal friction, underscores that the industry now has substantial products and market stakes to contest. The challenge is no longer just technical breakthrough but transforming technological leads into sustainable commercial success through superior patents, product performance, cost control, and customer acquisition. Chinese companies are finally positioned to compete for a share of this lucrative market long held by foreign leaders.

Zhang Lei: How He Became the Biggest Money-Maker This Year

Zhang Lei's company Pinzhun Laser (频准激光) became the biggest "meat sign" (highly profitable new share) of the year on its A-share market debut. Its stock price skyrocketed nearly 600% from its IPO price, generating potential single-lot profits of over 550,000 RMB for lucky subscribers. Founded by Zhang Lei, a 2014 Ph.D. graduate from the Shanghai Institute of Optics and Fine Mechanics, Pinzhun Laser specializes in ultra-stable, narrow-linewidth lasers critical for quantum computing. Its lasers are used by leading global research teams at Harvard, Caltech, and France's PASQAL. The company later successfully applied its core frequency conversion technology to the semiconductor sector, developing deep-ultraviolet lasers for advanced chip manufacturing and inspection. This move diversified its revenue, with semiconductor sales growing rapidly to account for over 25% of its business by 2025. The company boasts gross margins consistently above 69%. Remarkably, Pinzhun Laser required only two major external funding rounds before its IPO, a testament to its early profitability. Key strategic investors in its IPO included major downstream players like BOE,佰维存储 (BIWIN), and中微半导体 (AMEC), signaling strong industry validation. The article highlights the crucial early-stage support from Hangzhou-based capital, particularly funds associated with the Hangzhou Institute of Optics and Fine Mechanics. This "patient capital" model, part of Hangzhou's broader 300-billion-yuan industrial fund strategy, focuses on partnering with scientist-entrepreneurs through the risky valley of death from lab to market. The success of Pinzhun Laser and another Hangzhou-backed firm,宇树科技 (Unitree Robotics), showcases how this supportive ecosystem helps build leading hard-tech companies.

3-Month Loss of $10 Billion, DAT Companies Begin to Return to Rationality

During the recent earnings season, major Digital Asset Treasury (DAT) companies reported staggering combined losses of approximately $10 billion for Q2 and over $30 billion for the first half, primarily due to markdowns on their bitcoin holdings. However, contrary to expectations, their stock prices have rebounded from June lows, indicating the market had already priced in these losses. The key shift is a collective return to rationality. Companies like Strategy, Sharplink, and Metaplanet are now prioritizing a new core metric: increasing the amount of crypto assets per share. This marks a departure from last year's aggressive growth-at-all-costs narrative. To achieve this, they are adopting disciplined capital allocation—issuing stock to buy crypto when trading at a premium, and halting dilution or initiating buybacks when at a discount. Some, like Strategy, have even broken "never sell" pledges to uphold this discipline. A major tool enabling this strategy is the STRC model—perpetual preferred shares offering high dividends (e.g., 12-13%) to raise fixed-income capital for purchasing bitcoin. Strive, Bitmine, and Metaplanet have launched their own variants. Sharplink pursues a different path, staking its vast Ethereum holdings to generate native yield. While the premium of DAT stocks over their underlying crypto asset value has declined and may not fully return, the model is evolving rather than ending. Stripped of hype, DAT firms are becoming actively managed, leveraged thematic funds. Their survival through massive losses and continued institutional investment (with major funds adding billions to positions during downturns) suggests the industry is maturing into a more calculated, long-term business focused on compounding crypto per share.

PI Price Forecast Remains Stable at $0.086 as Pi Network Reforms App Economy

PI price forecast remains stable around $0.086 as it continues to trade below a key descending trendline from April. The token has been consolidating in a narrow range between $0.078 and $0.086 throughout August, with major EMAs positioned above the price indicating bearish pressure. Key resistance levels are identified at the 20-day EMA ($0.08772) and the SuperTrend indicators around $0.09-$0.10. Support sits at the current price and the August range low of $0.070. Fundamentally, Pi Network announced a major change to its App Studio pricing model, set for August 24, 2026. The fixed, subsidized rate of 0.25 Pi for app creation/editing will shift to a usage-based model reflecting actual AI service costs. Subsidized rates will remain for apps demonstrating genuine user adoption. Separately, the mandatory node protocol upgrade has reached version 26.1, with only version 27.1 remaining to complete the sequence. On-chain activity shows increased transaction volume, including patterns of repeated 0.03 Pi transfers, potentially related to testing following the protocol upgrade. The bullish scenario targets a break above the $0.08772-$0.09000 resistance cluster, opening a path toward the 50-day EMA at $0.09560. The bearish risk is a breakdown below the consolidation range, potentially testing the $0.070 support level. The conclusion notes that while fundamental developments are progressing, the price chart remains technically constrained until it can decisively break above the persistent downtrend line and key moving averages.
