Grayscale highlights Ethereum and Solana’s dominance in on‑chain

Ethereum remains the primary settlement layer for on‑chain finance, controlling the majority of stablecoin balances, DeFi value locked and tokenized U.S. Treasury products, according to Grayscale’s research team [1]. The firm also notes that Solana and other blockchains are positioned to benefit as the industry seeks clearer regulatory guidance, though the specifics of that guidance are not detailed in the available sources.

Key takeaways

• Ethereum holds over 50% of stablecoin balances and about 65% of DeFi total value locked [1].
• Roughly 80% of tokenized U.S. Treasury assets reside on Ethereum [1].
• Solana processes more transactions than Ethereum, emphasizing speed as a competitive edge [3].
• Institutional inflows into Ethereum‑linked products reached $5.4 billion in July [1].
• The impact of upcoming regulatory clarity on these chains is not quantified in the sources [?].

Ethereum’s financial plumbing

Grayscale’s research, led by Zach Pandl, quantifies Ethereum’s grip on three core pillars of on‑chain finance. The ecosystem, including its Layer 2 rollups, holds more than half of all stablecoin balances and handles roughly 45% of stablecoin transaction value [1]. In decentralized finance, Ethereum accounts for about two‑thirds of total value locked, underscoring its role as the backbone of lending, borrowing and trading protocols [1]. Tokenized U.S. Treasury products—digital representations of government debt—are overwhelmingly concentrated on Ethereum, with nearly 80% residing on the network [1].

Solana and other chains gaining traction

While Ethereum dominates volume and value, competitors such as Solana and BNB Chain are advancing on speed and cost efficiency. Solana, designed for high throughput, consistently processes more transactions than Ethereum, though the transactions are generally of lower monetary value [3]. This speed advantage is highlighted as a key differentiator for Solana’s growth, especially as it pursues partnerships with traditional finance firms [3]. Grayscale’s analysis acknowledges that 55% of stablecoin transaction value occurs outside Ethereum, indicating room for other chains to capture market share [1].

Why it matters

The data suggest that Ethereum’s entrenched infrastructure continues to attract institutional capital, as evidenced by $5.4 billion of net inflows into spot ETH exchange‑traded products in July [1]. At the same time, the rise of faster, lower‑cost chains like Solana points to a diversifying ecosystem where regulatory clarity could shape capital allocation across multiple blockchains. While Grayscale highlights the potential benefits for Ethereum, Solana and two unnamed chains, the exact impact of any forthcoming “Clarity Act” remains unspecified in the sources. Investors and policymakers will likely watch how these networks balance transaction volume, value, and regulatory compliance in the coming months.
