Ethereum's Dominance in Stablecoin Revenue Generation: The Core Infrastructure for On-Chain Finance

Ethereum's role in the blockchain ecosystem has evolved dramatically in 2025, transitioning from a speculative asset to the foundational infrastructure for on-chain finance. Despite challenges like declining Layer 1 (L1) revenue and competition from Layer 2 solutions, Ethereum remains the bedrock for stablecoin activity, real-world asset (RWA) tokenization, and institutional-grade financial infrastructure. This analysis explores how Ethereum's dominance in stablecoin revenue generation-driven by its composability, security, and institutional adoption-positions it as a critical asset for long-term investors.

The Surge in Stablecoin Transaction Volume

Ethereum's stablecoin network activity reached unprecedented levels in Q4 2025, processing $8 trillion in stablecoin transfers-a near doubling from the $4 trillion recorded in Q2. This surge reflects a broader shift in stablecoin usage from speculative trading to real-world payments, as highlighted by analysts. The network's ability to handle such massive volumes underscores its role as the go-to settlement layer for global on-chain finance.

While Ethereum's L1 revenue has declined due to migration to Layer 2 solutions, the base layer remains indispensable for stablecoin issuance and governance. Tether (USDT) and USD Coin (USDC), which collectively control over two-thirds of the stablecoin market, rely heavily on Ethereum's infrastructure. For instance, USDT's Ethereum-based supply alone reached $103 billion in Q4 2025, demonstrating the network's entrenched position in the stablecoin ecosystem.

Stablecoin Issuance and Market Share Leadership

Ethereum's dominance in stablecoin issuance is equally compelling. By year-end 2025, the network accounted for , far outpacing Tron's 27% and Binance's 7%. This leadership is driven by Ethereum's EVM compatibility, which allows seamless integration with decentralized finance (DeFi) protocols and institutional-grade custodians.

Tether (USDT), the largest stablecoin issuer, maintained $187 billion in circulation in 2025, with over half of its supply on Ethereum. This concentration of issuance on Ethereum translates into significant protocol-level revenue. According to Token Terminal, stablecoin issuers generated $5 billion in revenue on Ethereum in 2025, leveraging the network's transparency and liquidity to create composable financial products.

Protocol Yields and the Layer 2 Paradox

While Ethereum's share of app revenue has declined from 50% to 25% since early 2024, this shift reflects broader industry trends rather than a loss of relevance. The rise of Layer 2 solutions like Arbitrum and Optimism has enabled lower transaction fees and higher throughput, but Ethereum's base layer remains the settlement layer for these networks. This creates a paradox: Ethereum's revenue is shrinking, but its value as infrastructure is expanding according to analysis.

For example, stablecoin transfers on Ethereum's Layer 2 networks now account for over 40% of total volume, yet the base layer still captures the majority of protocol yields through staking and governance. Ethereum's staking activity has also grown, with institutional participation driving security and decentralization. This duality-lower direct fees but higher systemic importance-positions Ethereum as a "public utility" for global finance.

Real-World Asset Tokenization: The Next Frontier

Ethereum's dominance extends beyond stablecoins into RWA tokenization. By Q4 2025, the network held , or approximately $19 billion. When Layer 2 and EVM-compatible chains are included, Ethereum's share exceeds 70%. This growth is fueled by Ethereum's ability to tokenize real-world assets like real estate, bonds, and commodities, creating a bridge between traditional and digital finance.

The tokenization of RWAs on Ethereum is not just a technical achievement-it's a revenue driver. Protocols like MakerDAO and Aave are already integrating RWA-backed collateral into their lending markets, generating yield for stakeholders. As institutional adoption accelerates, Ethereum's role as the settlement layer for these assets will become even more critical.

Conclusion: Ethereum as the Core Infrastructure

Ethereum's dominance in stablecoin revenue generation is not a function of short-term metrics but a reflection of its role as the core infrastructure for on-chain finance. While L1 revenue has declined, the network's leadership in stablecoin issuance, RWA tokenization, and institutional-grade security ensures its long-term relevance. For investors, this means Ethereum is not just a speculative asset-it's the bedrock of a new financial system.

As the blockchain industry matures, Ethereum's ability to adapt while maintaining its foundational role will be its greatest strength. The data from 2025-$8 trillion in stablecoin transfers, $5 billion in protocol yields, and 65% RWA market share-confirms that Ethereum is not just surviving; it's evolving into the infrastructure layer for the next decade of on-chain finance.
