Ethereum experienced substantial growth in decentralized finance (DeFi) and stablecoin sectors throughout 2025. Data from DefiLlama indicated that Ethereum’s total value locked (TVL) in DeFi exceeded $99 billion, outpacing the next largest Layer 1 ecosystem by more than ninefold. The network also facilitated the settlement of $18.8 trillion in stablecoin transactions, coinciding with a significant decline in transaction costs.
Lower transaction fees were a pivotal factor contributing to this growth. Fees on Ethereum’s main Layer 1 dropped to their lowest in five years, while Layer 2 networks recorded transaction costs below $0.01. This reduction in expenses benefited users involved in payments, remittances, and savings activities. Additionally, enhanced paymaster infrastructure allowed applications to absorb transaction fees, eliminating the necessity for users to hold ETH for gas fees.
Crypto platforms expanded their engagement with Ethereum during the year. Robinhood, Gemini, and Kraken introduced tokenized stocks on Ethereum’s Layer 1 and Layer 2 networks, extending access to U.S. equities beyond traditional market hours. Robinhood further announced intentions to develop its own Layer 2 network utilizing Arbitrum’s Orbit technology.
Regulatory clarity also played a role in fostering the growth of crypto-focused neobanks. These institutions launched payment cards and rewards programs, reporting substantial daily spending volumes.
Beyond DeFi and stablecoins, Ethereum’s ecosystem witnessed expansion in institutional and technological domains. Institutional involvement increased, with over $35 billion of ETH held in exchange-traded funds and strategic reserves. More institutions adopted Ethereum smart contracts for on-chain capital management and DeFi yield strategies, amounting to over $12 billion in real-world asset distribution.
Significant advancements were made in Ethereum’s rollup-focused roadmap. Layer 2 networks achieved an average throughput of 5,600 transactions per second. The Fusaka upgrade, implemented in December, enhanced blob capacity and reduced Layer 2 costs. Furthermore, the Layer 1 gas limit rose to 60 million, expanding settlement capacity by approximately 33%.
Marking its 10th anniversary in July 2025, Ethereum celebrated the deployment of over 88 million smart contracts. Daily transactions reached a peak of 1.74 million, reflecting robust activity. Developer engagement remained high, with 32,000 active developers in the ecosystem and over 16,000 new members joining between January and September.
To understand the broader implications, it’s vital to consider the dynamics of the decentralized finance sector. DeFi allows financial services such as lending, borrowing, and trading to occur on blockchain platforms without traditional intermediaries. Ethereum, being a foundational technology for many DeFi applications, benefits from increased adoption and innovation. Stablecoins, which are cryptocurrencies pegged to traditional currencies like the U.S. dollar, enable smoother transactions and have become integral to DeFi operations.
The decrease in transaction costs has been a game-changer. Historically, high fees have deterred smaller transactions and limited the accessibility of Ethereum-based services. The reduction of costs on Layer 2 solutions makes Ethereum more attractive for everyday use, expanding its user base and application potential.
The introduction of tokenized stocks on Ethereum further illustrates the network’s versatility. By facilitating 24/7 trading of U.S. equities, these platforms are leveraging blockchain technology to offer services beyond the capabilities of traditional stock exchanges.
Institutional interest in Ethereum is driven by the potential for higher returns and diversified investment strategies within the crypto space. As financial institutions seek to meet client demand for digital assets, Ethereum’s infrastructure provides a reliable platform to explore these opportunities.
From a regulatory standpoint, clarity is crucial for the continued growth of crypto products. Clear regulations enable companies to innovate with confidence, knowing they are operating within legal boundaries. This environment encourages the development of more sophisticated financial products and services.
Despite these positive developments, several risks remain. The cryptocurrency market is known for its volatility, which can affect asset values and transaction stability. Additionally, operational risks such as technical failures or security breaches pose challenges. Regulatory changes or enforcement actions could also impact the landscape, influencing market conditions and investor sentiment.
In terms of next steps, stakeholders will closely monitor ongoing infrastructure upgrades and potential regulatory updates. The evolution of Ethereum’s technological roadmap and its ability to maintain security and efficiency will be critical to sustaining its growth. As interest in digital assets continues to rise, the balance between innovation and regulation will shape the future of Ethereum and the broader blockchain ecosystem.
