Ethereum ETF Gains May Be Limited – Grayscale Highlights Solana as Top Competitor

·

The latest research from Grayscale Research offers a comprehensive outlook on Ethereum’s current state, adoption trajectory, and competitive positioning in the smart contract blockchain landscape. While the upcoming spot Ethereum ETF is expected to boost demand and visibility for ETH, Grayscale suggests its price upside may be more constrained compared to Bitcoin’s post-ETF rally. At the same time, the report singles out Solana (SOL) as the most credible long-term challenger to Ethereum’s dominance.

This analysis dives into key developments—from Layer 2 adoption and tokenomics shifts to ETF expectations and competitive dynamics—providing investors and crypto enthusiasts with a data-driven perspective on where Ethereum stands and where it might be headed.

Ethereum’s Shift Toward Modular Architecture

Following the pivotal Cancun upgrade in March 2024, Ethereum has accelerated its transition toward a modular blockchain architecture. This design philosophy separates core functions—execution, settlement, consensus, and data availability—into specialized components that work together seamlessly.

In this model, Layer 2 (L2) networks play a critical role by processing transactions off the mainnet while still relying on Ethereum’s Layer 1 (L1) for security and finality. L2s bundle and post transaction data back to L1, benefiting from Ethereum’s robust decentralization and cryptographic trust.

This contrasts sharply with monolithic blockchains like Solana, where all operations occur on a single layer. While monolithic designs can offer high throughput, they face trade-offs in scalability, resilience, and long-term sustainability under heavy load.

From an activity standpoint, Ethereum’s modular approach is proving effective: approximately two-thirds of all on-chain activity now takes place on L2 solutions, signaling strong user adoption and confidence in scaling technologies like rollups.

Declining L1 Revenue and Its Impact on ETH Supply

Despite growing L2 usage, a notable side effect has emerged: Ethereum’s mainnet revenue has declined. Since most transactions now occur off-chain or on L2s, fewer fees are being paid directly to L1 validators.

This shift affects Ethereum’s token economics, particularly its deflationary mechanism. Under normal conditions, high network usage leads to significant ETH burn via the EIP-1559 fee structure—where base fees are destroyed—potentially making ETH deflationary when burns exceed issuance.

However, with lower L1 activity, fee income has dropped, reducing the rate of ETH destruction. As a result, net ETH supply has begun increasing again, reversing previous deflationary trends.

Although L2s still pay costs to publish data on L1—such as blob fees—these amounts are relatively small compared to direct transaction fees during peak L1 congestion.

How Can Ethereum Restore Positive Supply Pressure?

Grayscale emphasizes that for ETH to appreciate sustainably over time, Ethereum’s L1 must see rising fee revenue. There are two primary pathways:

  1. Moderate growth in high-value L1 transactions, such as large transfers or critical smart contract interactions.
  2. Explosive growth in L2 activity, which indirectly boosts L1 revenue through increased data posting (e.g., frequent blob submissions).

Ideally, Ethereum evolves into a hybrid ecosystem:

Evidence already supports this trend. For instance:

This division of labor could ensure both layers thrive without cannibalizing each other.

Spot Ethereum ETF: Demand Outlook and Supply Constraints

The anticipated approval of a spot Ethereum ETF in the U.S. is widely seen as a bullish catalyst for ETH prices. Grayscale draws parallels with existing Ethereum ETPs (Exchange Traded Products) outside the U.S., which have historically captured 25–30% of Bitcoin ETP inflows.

Based on this ratio, Grayscale estimates that Ethereum ETFs could attract $3.4 billion to $4.1 billion in net inflows—assuming Bitcoin ETFs’ $13.7 billion inflow since January 2024 remains the benchmark.

While U.S. ETH futures volume is only about 5% of BTC futures, Grayscale cautions against using this as a proxy for spot ETF demand. Institutional appetite may differ significantly once direct exposure becomes available through regulated products.

Limited Float Amplifies Price Sensitivity

One crucial factor: nearly 50% of ETH’s circulating supply is locked long-term, limiting available float for new buyers:

With half the supply effectively illiquid, any surge in demand—especially from ETF-driven institutional buying—could exert strong upward pressure on price due to constrained supply elasticity.

Why Solana Emerges as Ethereum’s Biggest Threat

Grayscale identifies two key headwinds for ETH:

1. Valuation at ETF Approval: Less Room to Run

Using the MVRV-Z Score—a metric that compares market value to realized value—Grayscale notes that Bitcoin was trading at a relatively neutral valuation when its spot ETF launched in January 2024. In contrast, Ethereum appears overvalued by historical standards, suggesting limited upside immediately following ETF approval.

2. Rising Competition from Solana

More significantly, Grayscale highlights Solana (SOL) as the most likely candidate to erode Ethereum’s market share over time.

As the second-largest smart contract platform by developer activity and ecosystem value, Solana has demonstrated:

In 2024, SOL outperformed ETH significantly, and the SOL/ETH exchange rate is nearing its previous cycle peak. While Grayscale expects short-term stabilization—supported by ETH’s ETF momentum—the long-term trend will hinge on relative growth in on-chain revenue between the two platforms.

If Solana continues capturing developer mindshare and user activity at a faster pace, it could redefine the smart contract leader board in coming years.

Frequently Asked Questions (FAQ)

Q: Will the spot Ethereum ETF definitely increase ETH’s price?
A: Not necessarily. While ETF approval typically boosts visibility and institutional demand, ETH’s current valuation and high locked supply mean gains may be more muted than Bitcoin’s post-ETF surge.

Q: Is Ethereum becoming obsolete because of Layer 2s?
A: No—quite the opposite. L2s strengthen Ethereum’s position by offloading computation while preserving security. Ethereum remains the foundational layer securing trillions in value across its ecosystem.

Q: How does Solana challenge Ethereum technically?
A: Solana uses a monolithic architecture optimized for speed and low cost, leveraging innovations like proof-of-history. However, it trades off some decentralization and resilience during outages.

Q: What does “modular blockchain” mean?
A: It refers to splitting blockchain functions across specialized layers—like execution (L2), settlement (bridges), and consensus (L1)—to improve scalability without sacrificing security.

Q: Can both Ethereum and Solana coexist successfully?
A: Yes. Different blockchains serve different needs. Ethereum excels in security and decentralization; Solana prioritizes performance. Coexistence allows developers and users to choose based on use case.

Q: How does staking affect ETH supply?
A: Over 27% of ETH is staked, removing it from liquid circulation. This reduces sell pressure and enhances scarcity, especially during periods of rising demand.
