Ethereum’s most recent upgrade, Fusaka, officially launched on December 3, 2025, introducing significant scaling enhancements aimed at simplifying user interactions with the network. Unlike prior upgrades that mainly concentrated on consensus mechanisms or transaction fee structures, Fusaka focuses on improving usability for everyday users, particularly those who may not be well-versed in concepts like private keys or complex wallet interfaces.
A standout feature of the Fusaka upgrade is the implementation of EIP-7951, which introduces a new type of cryptographic signature compatible with billions of devices globally, including smartphones and advanced hardware security keys. This enhancement allows Ethereum to leverage a secure login method that users are already accustomed to using for unlocking their devices and accessing applications.
Additionally, Fusaka incorporates a major upgrade known as PeerDAS, which significantly enhances the network’s data handling capabilities. This upgrade is expected to lead to lower and more stable costs on Layer-2 networks that process transactions for a vast number of users. Developers anticipate substantial reductions in transaction fees as the network’s capacity expands.
As Fusaka went live, Ethereum’s price experienced a notable upswing. In the 24 hours leading up to the upgrade, ETH saw an increase of approximately 9% to 10%, reclaiming the crucial $3,000 threshold after recovering from dips in the high-$2,700s. During the upgrade window, ETH fluctuated between $2,997 and $3,167, supported by a spike in trading volume that exceeded $30 billion. Following the launch, the price has stabilized, with traders now focusing on the pace of Layer-2 fee reductions and the potential for sustained momentum from future protocol adjustments.
Historically, Ethereum’s major upgrades have exhibited a recurring trend: while they often do not yield immediate substantial impacts, their economic effects tend to accrue over time. Analysts are monitoring key price levels for ETH as it hovers around $3,000. Resistance is identified in the range of $3,166 to $3,179, where approximately 2.76 million ETH is located, making it a formidable barrier to breach. Conversely, $2,800 is noted as a significant support level essential for maintaining the current upward trajectory, with additional support found between $2,700 and $2,760, a zone that previously attracted buying interest.
For the short term, market analysts anticipate a balanced outlook for ETH in the upcoming weeks, predicting fluctuations between the support zone of $2,800 and resistance around $3,150 to $3,200 as traders observe early metrics on Layer-2 fee reductions. A sustained breakout above resistance could pave the way toward the mid-$3,000s, while a decline below $2,800 would redirect attention back to the mid-$2,700s.
Looking to the medium term, projections for the first half of 2026 vary but often converge on several key themes. Some analysts posited medium-term targets in the $3,300 to $3,600 range, driven by fee savings and improved user experiences that could enhance network activity. In more bullish scenarios, predictions suggest ETH could surge to anywhere between $7,000 to $9,000, contingent on strong institutional investments and favorable macroeconomic conditions. However, some experts caution that upgrades by themselves may not directly trigger immediate multi-month rallies; instead, they create the groundwork for future growth once demand recovers.
The full implications of the Fusaka upgrade on ETH’s trajectory are anticipated to unfold gradually over the coming quarters rather than through a singular price surge.
