“The DeFi sector has matured and become safe,” is a statement by Vitalik Buterin that could serve as an ideal epigraph for the outcomes of 2025, if not for the harsh reality.
Almost simultaneously with these words, the crypto community was shaken by the news of the closure of the popular analytics service DappRadar. Shortly before that, Balancer lost $128 million in assets due to a flaw in one of its key platform components, reminding everyone of the fragility of this "financial Lego".
This dichotomy permeated the entirety of 2025. On one hand, there was a significant influx of institutional capital and record lending volumes, creating an image of stability. On the other hand, many metrics stagnated, projects closed down, and the epidemic of exploits continued unabated.
So what does DeFi truly represent at the end of 2025: a robust giant ready for integration into the global financial system, or a colossus on clay feet? Let’s try to unravel these contradictions.
Renaissance and Consolidation: The Facade of Prosperity
Despite underlying issues, 2025 indeed marked powerful trends that created an illusion of unprecedented stability and growth in DeFi. Behind this facade of prosperity were two key pillars: the active institutionalization of the sector and the formation of a healthier debt load.
These processes signaled a new stage of development, where speculative chaos gives way to more measured strategies.
First, let’s examine the dynamics of key metrics.
TVL and “Blue Chips”
As of December 30, 2025, the total TVL of the decentralized finance segment stands at approximately $118 billion.

Since mid-spring, the metric has shown impressive growth, nearing the record highs of late 2021—over $170 billion. However, a market correction followed, dragging the metric down.
As before, the dominant position is held by the Ethereum-based ecosystem, which accounts for nearly 70% of the segment, with a TVL close to $70 billion.
On December 4, a major upgrade Fusaka was activated. The upgrade aims to enhance scalability, efficiency, and security of the second-largest cryptocurrency.
The hard fork includes ten proposals for network improvements. A key innovation is the EIP-7594 standard, which implements the PeerDAS protocol. This technology allows validators to verify individual data fragments instead of entire BLOB objects, increasing their availability for the ecosystem.
Ethereum co-founder Vitalik Buterin called the protocol a critically important element for the network's development, noting that “this literally is sharding.”
PeerDAS in Fusaka is significant because it literally is sharding.

The upgrade also proposes more than a twofold increase in the gas limit at the first level (L1). Blockchain throughput is expected to rise to 12,000 TPS.
The price of the second-largest cryptocurrency reacted to the event with a 3.6% increase in one day, but the upward momentum later faded.
However, there were issues—shortly after the Fusaka deployment, a failure occurred in the popular consensus client Prysm, which disabled part of the Ethereum validators. The error was found in version v7.0.0: while processing attestations, the client incorrectly generated outdated blockchain states.
In second place in the popularity ranking is the collection of DeFi protocols based on Solana, which involves crypto assets worth over $8 billion. The Bitcoin-based ecosystem (BTCFi) ranks third in the DefiLlama ranking, with crypto assets totaling $6.7 billion.
Fourth is the BNB Chain with a TVL of around $6.5 billion. Fifth place goes to the collection of applications based on Base.
Below is the ranking of the largest protocols in the segment:

Leading the pack is the lending protocol Aave, supporting 18 networks. Its TVL exceeds $30 billion, creating a significant gap from competitors.
In the top three are the liquid staking platform Lido—around $26 billion—and the restaking project EigenLayer—approximately $12.5 billion.
Rounding out the top ten is the leading BTCFi project Babylon with a TVL of over $5 billion.
The growth of the segment in 2025 cannot be deemed sustainable. The monthly unique user count peaked at over 27 million in April, but then fell to 11.8 million as of December 30, 2025.

DEX vs. CEX
The largest DEX platforms like Uniswap, PancakeSwap, Meteora, and HumidiFi have shown relatively stable growth since early spring. The first two are the largest in the sector, with their combined market share approaching 50%.
Notably, the ratio of DEX turnover to the total trading volume on CEX surpassed 20% for the first time in June, indicating a growing popularity of decentralized solutions and methods for trading crypto assets. For comparison, this figure was only 6% in 2021.
Spot trading volumes on decentralized exchanges are significantly higher than in previous years. In October, the figure reached a record $419.76 billion, despite the correction.
In 2025, perp-DEX platforms like Lighter, Aster, and Hyperliquid gained significant popularity.
This relatively new category of decentralized platforms allows trading of cryptocurrencies and other derivatives with high leverage. These platforms support various types of orders and actively implement innovations. For example, in the fall, Hyperliquid launched custom perpetual contract markets as part of the HIP-3 update; their daily turnover soon exceeded $500 million.
The diagram below illustrates the alignment of market shares among platforms due to intensified competition:

“Similar to the situation with spot trading, decentralized exchanges have begun to actively increase their perp volumes, narrowing the gap with centralized platforms this year. November 2025 marked the 14th consecutive month where the share of DEX in the overall perp turnover showed consistent monthly growth,” noted CoinGecko.
Since the beginning of the year, turnover on Hyperliquid reached $2.74 trillion, comparable to the largest American crypto exchange, Coinbase. Analysts predict a shift from simple tokenization to the creation of synthetic instruments. Perp-RWA will provide traders with quick access to off-chain markets without the need to own the underlying asset.
Coinbase Ventures anticipates the “perpification of everything”: from shares of private companies to economic data. Investors will be able to hedge risks through instruments tied to oil, inflation, credit spreads, and volatility.
Institutionalization through RWA and Stablecoins
The main bridge through which large capital began flowing into decentralized finance was the integration of real-world assets and the explosive growth of the stablecoin sector.

As noted in the ARK Invest report, the tokenization of U.S. Treasury bonds, real estate, and private equity has ceased to be exotic and has become a working mechanism for attracting liquidity.

The strategic importance of mass adoption is immense. Firstly, this process enhances the legitimacy of the entire sector in the eyes of traditional investors and regulators. Secondly, the influx of capital backed by real assets significantly increases overall market liquidity.
Finally, it reduces systemic volatility, making DeFi tools more predictable and attractive to conservative players.
“Healthy” Leverage: Record Loans and the New Norm
Another prominent marker of the year was the rapid growth of the crypto lending sector—loan volumes in CeFi and DeFi reached a record $73.6 billion.

The figure is impressive, but the nature of this debt is even more important. Analysts increasingly speak of the onset of an era of “healthy leverage.” Unlike previous cycles, where debt loads were primarily formed through risky speculative positions, today a significant portion of loans is used for more conservative and long-term strategies.
The market seems to be learning lessons from cascade liquidations of the past. However, looking at this impressive figure raises the question: is this leverage truly safe, or has the industry simply learned to better mask systemic risks?
Complex derivatives and multi-layered chains of rehypothecation make the debt load less transparent. The potential hidden risk brings us back to the aforementioned image of a colossus on clay feet. Just a month ago, the capitalization of the synthetic stablecoin USDe from Ethena plummeted by over 50%.
The decline in the metric occurred against a backdrop of falling yields to 4.3% per annum compared to double-digit figures at the beginning of the year.

According to analysts from The Block, the main reason is the closure of leveraged strategies in DeFi protocols like Aave. Rehypothecation remained profitable as long as the yield of USDe exceeded the borrowing cost of USDC. However, when it fell below 5.4%, there was a mass exit from positions.
The financial facade, impressive as it may seem, began to crack when confronted with deleverage and the real pace of technological development in the sector.
Innovation Stalemate
Against the backdrop of financial growth, technological development in the sector in 2025 appeared ambiguous. It can be assumed that the influx of institutional capital aimed at stability and understandable RWA models inadvertently slowed the pace of fundamental innovations, shifting the focus from R&D in unexplored territories to more conservative solutions.
High-profile announcements and the launch of new protocols did not always lead to qualitative breakthroughs. Some key directions that were heavily invested in have even “stalled.”
BTCFi: Stalled Evolution
One of the main narratives at the beginning of the year was the BTCFi ecosystem—an ambitious attempt to integrate Bitcoin's massive liquidity into decentralized finance.
It was expected that this segment would become a new source of growth for all of DeFi. However, by the end of the year, it became evident that the declared “evolution” had effectively stalled.
Projects faced fundamental obstacles. Creating reliable and truly decentralized bridges for transferring value to other networks remains an unresolved challenge: vulnerabilities in such solutions can potentially lead to billions of dollars in losses.
Economically, the conservative Bitcoin community has largely not embraced such initiatives. This was reflected in relatively low growth rates of the corresponding protocols and a lack of support from key developers, who still prioritize HODL strategies over complex DeFi constructions.

As a result, BTCFi failed to emerge from its niche experiment status, becoming one of the major technological disappointments of 2025.
x402: Local Success with Caveats
Amid overall difficulties, local achievements stood out. A notable example is the x402 protocol, which offered a solution for micropayments in a Click-to-Pay format. The project confirmed that innovations in DeFi are still possible, especially in specific niches.
However, even this success cannot be deemed bright. Technical experts criticized the protocol, pointing out risks of centralization and inevitable architectural compromises.
Six months after its launch, the project team released a second version of the protocol aimed at creating a “single payment layer for the internet.”
The solution became “multichain by default”: it works with native tokens of Base, Solana, and other blockchains without requiring additional custom logic. Among the technical updates are simplified scenario creation, improved wallet interactions, and integration of traditional payment systems.
The x402 case illustrates a broader trend: successful products of 2025 address only specific tasks. They do not eliminate fundamental issues like scalability or security.
The Harsh Truth
The current growth metrics and the launch of new solutions mask the pitfalls in the industry: the culling of weak players and technical risks. Behind the graphs of TVL dynamics, the statistics of failures are often obscured, and the fact that a single error in a smart contract can still lead to multimillion-dollar losses remains.
The Graveyard of Projects: From DappRadar to the Cosmos Ecosystem
As in previous years, 2025 also saw the “washing out” of weak and unviable projects from the market. However, this process also affected once-promising players with clear value for the market:
- DappRadar: the well-known analytics platform ceased operations due to “financial instability” after a prolonged search for an effective business model;
- Cosmos ecosystem: in November, announcements were made regarding the cessation of operations or critical restructuring by Comdex, Kujira, Evmos, Picasso/Composable, Quasar/Tower, and Stride.
The failures of major projects indicate complex issues within the segment that cannot be attributed solely to the miscalculations of specific teams, financial difficulties, or developer outflows.
Incurable Disease: Hacks as a Constant
The key problem contradicting Vitalik Buterin's thesis about the safety of DeFi remains relevant—hacks continue unabated.
Attacks on Stream Finance or Balancer are just isolated examples. In the first quarter of 2025 alone, the Web3 ecosystem lost about $6 billion due to rug pulls.
Among other negative cases in recent months:
- Unauthorized withdrawal of crypto assets worth $3.1 million from the BNB platform GANA Payment;
- The disappearance of the project team Hypervault with $3.6 million;
- Exit scam of the CrediX protocol based on Sonic after a hack of $4.5 million;
- An attack on the blockchain Flow with damages of $3.9 million;
- Loss of $3.9 million by the Unleash Protocol.
Each of these incidents damages the industry’s reputation and confirms that vulnerabilities in smart contracts remain unaddressed and fundamental security issues are still relevant. As long as coding errors lead to colossal losses, it is premature to speak of the segment's maturity and its readiness for mass adoption.
DeFi at a Crossroads
In summarizing the year 2025, it can be stated that for DeFi, it was not a year of triumph but a period of maturation through crisis. The sector demonstrated a dual dynamic, combining signs of maturity with fundamental vulnerabilities.
The integration and acceptance of RWA, the expansion of stablecoins, and “healthy leverage” in the crypto lending segment indicate the industry’s ability to attract capital and build sustainable models. However, the unconvincing dynamics of BTCFi, a series of project closures, and regular security incidents cast doubt on the long-term prospects of the entire ecosystem.
On the other hand, some experts remain optimistic: co-founder of Chainlink Sergey Nazarov believes that the decentralized finance industry has already completed 30% of its journey towards mass adoption, with full acceptance expected by 2030.
Perhaps 2026 will be a defining year. The sector faces a choice: to return to genuine decentralization and technological reliability or to fully transform into a high-risk appendage of the traditional financial system.
