Cumulative fee revenue generated by decentralized finance (DeFi) protocols from early 2023 through May 2026 has reached approximately $25 billion, according to a new report from Unfolded. The data, courtesy of Token Terminal, highlights an important milestone for the industry and shows that DeFi platforms can generate real, measurable revenues beyond speculative trading activities.
DEXs provide half of all fee income
Decentralized exchanges (DEXs) were the main contributor, accounting for around half of the total fee revenue collected during this period. Their dominance reflects users’ continued demand for permissionless trading, especially in volatile market conditions where traders seek direct control over their assets. After DEXs, platforms offering liquid staking tokens (LSTs) emerged as the second largest source of revenue, with lending protocols and derivatives platforms also making meaningful contributions.
Sharp acceleration in turnover between 2025 and 2026
The report finds a particularly strong increase in fee generation between 2025 and 2026. This acceleration coincides with a broader market recovery and the maturity of several key DeFi applications, including more efficient automated market makers and improved cross-chain interoperability solutions. The growth suggests that DeFi is moving from an experimental phase to a more established financial infrastructure layer.
Revenue concentration remains a risk
Unfolded described DeFi’s ability to generate real income and support cash flow-based valuation logic as a major achievement for the sector. However, the company also warned that revenue sources remain heavily concentrated in specific verticals, particularly DEXs and LSTs. This lack of diversification means that the overall ecosystem is still vulnerable to shocks affecting these dominant sectors. For DeFi to achieve long-term stability, a broader distribution of revenues across lending, derivatives, insurance, and other use cases will be necessary.
Conclusion
The $25 billion milestone underlines DeFi’s growing economic footprint and its potential to underpin fundamental valuation models. Yet the concentration of revenue in a handful of protocol types highlights an ongoing structural challenge. As the sector continues to develop, achieving a more balanced revenue mix will be critical to reducing systemic risks and attracting mainstream institutional participation.
Frequently asked questions
Question 1: What is the cumulative fee income in DeFi?
It is the total amount of fees collected by the DeFi protocols for user transactions, trading, lending, staking, and other activities over a given period of time. It serves as an important metric for measuring protocol usage and economic value.
Question 2: Why did reimbursement revenue increase between 2025 and 2026?
The spike is attributed to a broader recovery in the crypto market, increased trading volume on DEXs, and the growing adoption of liquid staking and lending platforms. Technology improvements in scalability and user experience have also contributed.
Question 3: Is Income Concentration a Problem for DeFi?
Yes. The heavy reliance on a few protocol types – mainly DEXs and LSTs – makes the ecosystem vulnerable to sector-specific downturns. Greater diversification across lending, derivatives, insurance and other industries would strengthen resilience.
