Ethereum Hits 3-Week High as Shark Wallets Accumulate and Fusaka Rollup Boosts Network Activity
Data verified and updated as of November 2025
Ethereum surged to a three-week high on Wednesday as on-chain data revealed a sharp uptick in accumulation by so-called “shark” wallets — typically defined as addresses holding between 100 and 10,000 ETH. The renewed buying interest coincides with the successful deployment of Fusaka, a new rollup technology that has accelerated on-chain activity and reinvigorated sentiment across the Ethereum ecosystem.
The convergence of network innovation and mid-tier investor demand is now shaping a potential short-term recovery narrative for Ethereum, even as broader market conditions remain fragile following recent volatility.
Shark Wallets Accumulate Aggressively as Market Recovers
Blockchain analytics firms report that mid-sized investors have been steadily absorbing supply over the past 10 days, reversing the outflows seen during earlier stages of market uncertainty. According to aggregated on-chain tracking:
- Shark wallets added an estimated 120,000 ETH in less than two weeks.
- Withdrawal activity from centralised exchanges increased, indicating long-term positioning.
- Net flows into self-custody wallets hit their highest level since early October.
Analysts view this buying pattern as early-phase accumulation, typically seen before broader retail participation begins to return. While whale wallets (holding over 10,000 ETH) remain relatively neutral, the behaviour of shark wallets often precedes wider price movements.
Fusaka Deployment Boosts Network Confidence
A major catalyst for Ethereum’s renewed momentum is the rollout of Fusaka, a next-generation rollup architecture designed to improve throughput, reduce settlement costs, and enhance composability between Layer-2 environments.
Key features highlighted by developers include:
- Modular execution layers, enabling faster and cheaper transactions
- Improved cross-rollup bridging, reducing fragmentation across L2 ecosystems
- Dynamic settlement batching, lowering congestion during peak periods
The deployment has already resulted in a surge in Layer-2 activity, reflected in heightened bridged volumes, increased validator participation, and rising gas consumption from rollup-related operations.
Market strategists argue that Fusaka reinforces Ethereum’s long-term scaling roadmap, especially as the network continues to face competitive pressure from high-performance chains such as Solana, Sui, and Near.
Price Reclaims Key Resistance Levels
Ethereum’s price briefly touched the three-week high near the $3,750 zone, clearing two important technical levels:
- 200-day moving average (DMA)
- Major descending resistance line from mid-October
This breakout suggests a shift in near-term momentum:
- Momentum oscillators have moved out of oversold territory.
- Daily trading volume has increased by more than 40%.
- Funding rates across futures markets have normalised after the prior correction.
Technical analysts warn, however, that a sustained upward move requires confirmation from higher-time-frame closes above $3,700–$3,760. Failure to hold this zone could open the door to renewed selling pressure.
Market Sentiment Improves, but Risk Factors Remain
Although accumulation and technological progress have driven optimism, the macro backdrop for crypto remains delicate. Several risk factors may restrain Ethereum’s advance:
- Uncertain Federal Reserve policy path, with rate cuts still not guaranteed
- Weak liquidity conditions across altcoins
- Reduced institutional flows into Ethereum-related investment products
- High sensitivity to Bitcoin volatility, especially ahead of major derivatives expiries
Still, analysts emphasise that Ethereum’s relative resilience — especially compared with smaller altcoins — signals growing investor confidence around its fundamental value.
On-Chain Indicators Paint a Constructive Picture
Beyond accumulation by shark wallets, additional indicators support a cautiously bullish outlook:
1. Declining Exchange Supply
ETH on exchanges has fallen to a two-month low, suggesting reduced sell-side pressure.
2. Rising Staking Participation
Staked ETH now exceeds 32.6 million, reflecting long-horizon commitment from validators.
3. Healthier Liquidation Profiles
Recent corrections flushed out excessive leverage, reducing the probability of cascading liquidations.
Together, these metrics imply that Ethereum may be entering a more stable consolidation phase, with the potential for upward continuation if broader market conditions cooperate.
Outlook: A Turning Point or Just Relief?
Whether Ethereum’s latest rally marks the start of a more substantial recovery or merely a relief bounce depends on several upcoming catalysts:
- The next US economic data releases
- Progress on Layer-2 adoption following Fusaka
- Stability in Bitcoin’s derivatives markets
- Continued accumulation behaviour from shark and whale cohorts
If current on-chain trends persist, analysts believe Ethereum could challenge the $3,900–$4,000 resistance zone in the coming weeks. But failure to hold recent gains may push ETH back toward the $3,450 support area.
For now, the combination of shark wallet accumulation and Fusaka-driven network optimism has given Ethereum its strongest short-term foundation in nearly a month.
