Ethereum's Role in the Rapid Expansion of Stablecoin Ecosystems: On-Chain Infrastructure Demand and ETH's Value Capture

Ethereum's dominance in the stablecoin ecosystem has solidified its position as the foundational infrastructure for digital dollar transactions, with profound implications for ETH's utility and value capture. By September 2025, Ethereum hosts 57% of the global stablecoin supply, amounting to $170 billion, driven by institutional adoption, Layer 2 (L2) scalability, and DeFi integration, according to the Stablecoin Industry Report. This growth is not merely a function of market share but a reflection of Ethereum's evolving role as a reserve asset and settlement layer, directly tied to on-chain infrastructure demand and ETH's economic utility.

Ethereum's Infrastructure Dominance: A Catalyst for Stablecoin Growth

Ethereum's secure, programmable blockchain has become the default platform for stablecoin issuance, with Tether's USDT and Circle's USDC accounting for 85% of its stablecoin supply ($87.8 billion and $48 billion, respectively), according to Ethereum stablecoin supply data. This dominance is underpinned by Ethereum's institutional-grade security, political neutrality, and compliance-ready infrastructure, aligning with Electric Capital's criteria for stablecoin platforms, as discussed in a Cointelegraph analysis. The network's ability to tokenize real-world assets (RWAs) and support decentralized finance (DeFi) protocols has further amplified its appeal, with stablecoin liquidity fueling $19 billion in DeFi loans and $10 billion in tokenized RWAs, according to a JuCoin analysis.

The surge in stablecoin activity has been amplified by Ethereum's gas fee reductions, averaging $0.37 per transaction in September 2025-a 95% drop from 2024 levels, per an Ethereum gas fee reduction analysis. This decline, driven by the Dencun upgrade (EIP-7999) and L2 solutions like Arbitrum and Base, has made stablecoin transfers and DeFi interactions more accessible. For instance, L2 networks process over 1.9 million daily transactions at fees under $0.01, compared to $3.78 on the mainnet, according to Layer 2 gas markets. These improvements have enabled Ethereum to handle $22 million in monthly stablecoin payments by late 2024, with $3 trillion settled on-chain in August 2025 alone, per The Market Periodical.

ETH's Utility: From Gas to Collateral and Reserve Asset

Ethereum's native token, ETH, has transitioned from a utility token to a reserve asset, with its demand tied to stablecoin protocols and infrastructure usage. Over 54% of global stablecoins are issued on Ethereum, requiring ETH for gas, collateral, and staking, according to a Capwolf analysis. For example, banks launching stablecoins on Ethereum could become its largest holders in 2025, as noted in a Blockchain.News report. This structural demand is reinforced by Ethereum's deflationary mechanisms, including EIP-1559's base fee burn model, which reduces ETH supply and enhances its scarcity, as explained in an ETH gas fees guide.

Moreover, ETH's role as collateral in stablecoin protocols has expanded. Platforms like Aave and Uniswap rely on Ethereum's liquidity to facilitate lending, trading, and yield generation, with total value locked (TVL) rising in tandem with stablecoin supply, per a CoinCentral article. Institutional adoption has further cemented ETH's status as a reserve asset, with 51 corporations now holding ETH in treasuries and the Strategic Ethereum Reserve (SER) projected to surpass 10 million ETH by 2026, according to the JuCoin analysis.

Infrastructure Demand and Value Capture

The interplay between stablecoin activity and Ethereum's infrastructure demand directly enhances ETH's value capture. While the exact percentage of gas fees attributed to stablecoin transactions remains unspecified, the overall reduction in fees has democratized access to the network. For instance, simple stablecoin transfers now cost as little as $0.39 instead of $86, enabling mass adoption, according to a MEXC guide. Additionally, L2 solutions like Base generate $185,291 in daily revenue from priority fees, driven by stablecoin and DEX activity, the coinlaw report shows.

This infrastructure-driven demand is further amplified by Ethereum's role in tokenized cash and cross-border payments. McKinsey notes that Ethereum's secure, interoperable infrastructure is redefining stablecoin payments, with banks and corporations integrating it for next-gen financial systems in a McKinsey note. As stablecoin flows expand beyond 1% of global money transfers, Ethereum's position as a settlement layer will likely strengthen, reinforcing ETH's utility and scarcity.

Conclusion: A Network Reinvented

Ethereum's dominance in the stablecoin ecosystem is not accidental but a result of strategic upgrades, institutional adoption, and infrastructure innovation. The Dencun upgrade and L2 solutions have reduced friction, while ETH's role as a reserve asset and collateral has created a flywheel of demand. For investors, this translates to a network where ETH's utility is increasingly tied to real-world economic activity, from stablecoin issuance to DeFi and RWAs. As the on-chain economy matures, Ethereum's ability to capture value through infrastructure demand will remain a critical driver of its long-term growth.
