Ethereum Still Leads DeFi, So Why Is Its Market Share Falling?

Ethereum's position in decentralized finance looks increasingly contradictory. At the beginning of 2025, Ethereum represented roughly 63.5% of total DeFi TVL. By May 2026, that share had fallen to approximately 53–54%. At first glance, that looks like a major loss of power.

But the other side of the equation matters. Ethereum still held roughly $45 billion in DeFi TVL around the May 2026 snapshot, leaving it with an enormous pool of capital even after its percentage of the overall market declined. That creates a more useful question than simply asking whether Ethereum is losing DeFi:

Is Ethereum losing DeFi activity, or is DeFi growing faster outside Ethereum?

That distinction is at the center of the Ethereum DeFi dominance debate in 2026. The important point is that a declining percentage does not automatically mean a shrinking economy. Ethereum can remain a major liquidity, settlement and infrastructure layer while other networks capture a larger portion of the growth.

Ethereum DeFi Dominance: The 63.5% to 53–54% Study Case

Before looking at competitors, the percentage itself needs to be understood.

The historical comparison is useful because it shows how much Ethereum's share changed. The current stablecoin picture is equally important: DeFiLlama's September 2026 dashboard puts total stablecoin market capitalization at roughly $305 billion, with USDT around $183.4 billion and USDC around $74.4 billion.

The headline number, therefore, is not simply that Ethereum lost roughly 10 percentage points of DeFi dominance.

The better description is:

The more accurate description is that Ethereum DeFi TVL share contracted by roughly 10 percentage points, falling from about 63.5% to 53–54%. However, Ethereum still maintained a very large DeFi economy in absolute terms, showing that a declining market share does not necessarily mean Ethereum is losing its overall relevance in decentralized finance.

That difference changes the interpretation considerably.

Market Share Can Fall Even When Ethereum's DeFi Economy Remains Huge

Market share is a ratio. That means Ethereum's percentage can fall even if its own TVL does not collapse.

Absolute TVL vs. TVL Share

Consider a simple example.

Scenario A

• Ethereum TVL: $60 billion → $50 billion
• Total DeFi TVL: $95 billion → $100 billion

Ethereum loses $10 billion while the broader market grows. Its share falls substantially.

Now consider the opposite.

Scenario B

• Ethereum TVL: $45 billion → $50 billion
• Total DeFi TVL: $70 billion → $100 billion

Ethereum gains $5 billion.

Yet its market share still falls.

Why?

Because the rest of DeFi grew by much more.

This is the simplest way to understand the current Ethereum DeFi dominance debate.

A falling percentage can represent relative underperformance rather than absolute collapse.

Why the Difference Matters

If Ethereum's TVL falls sharply and competing chains simultaneously gain liquidity, that would be evidence of capital migration.

But if Ethereum remains stable or grows while Solana, Base, BNB Chain, Arbitrum and other networks grow faster, the story is different.

The market is not necessarily abandoning Ethereum.

It may simply be expanding beyond Ethereum.

The Other Half of the Story Is What Happened Outside Ethereum

If Ethereum's share declined, the missing percentage did not disappear.

It was redistributed across an increasingly competitive collection of blockchain ecosystems.

The important competitors are not identical. They attract different users, applications and types of capital.

Solana

Solana has become particularly important for high-frequency, trading-oriented DeFi.

Its appeal comes from:

• High transaction throughput
• Low transaction costs
• Fast execution
• Strong decentralized exchange activity
• A large trading-focused user base
• Deep liquidity across several major applications

Current DeFiLlama data illustrates the difference between capital and activity. Solana currently records roughly $68.4 billion in 30-day DEX volume, compared with about $36.9 billion for Ethereum.

That does not mean Solana has replaced Ethereum.

It demonstrates something more important:

A network can capture substantial economic activity without matching Ethereum's historical TVL position.

BNB Chain

BNB Chain has another competitive advantage: scale among retail-oriented users.

Its ecosystem benefits from:

• Low transaction costs
• Large existing user distribution
• Stablecoin activity
• Broad retail participation
• A mature exchange-connected ecosystem

The result is a different form of DeFi competition.

Ethereum has historically attracted significant capital-intensive applications and deep protocol liquidity, while BNB Chain can compete strongly where transaction frequency and accessibility matter.

Base

Base is arguably the most interesting case because it complicates the definition of Ethereum itself. Base is connected directly to the Ethereum ecosystem, but activity on Base is generally measured as Base activity rather than Ethereum L1 activity. That means Ethereum can effectively expand its broader ecosystem while its L1 share of DeFi TVL declines.

Current DeFiLlama data shows Base with roughly $5.65 billion in DeFi TVL, approximately $4.94 billion in stablecoins, and close to $1 billion in daily DEX volume. Base therefore provides an important example of why Ethereum DeFi dominance cannot be understood through Ethereum L1 TVL alone.

Other Growing Ecosystems

The same structural shift can be seen across other networks, including:

• Arbitrum
• Hyperliquid
• Avalanche
• Sui
• Tron
• Monad
• Polygon
• Other emerging ecosystems

The point is not to create another blockchain ranking. The bigger development is that DeFi is becoming geographically distributed across blockchains. Ethereum no longer needs to host every dollar and every transaction for Ethereum-based infrastructure to remain influential.

Ethereum's Layer-2 Strategy Makes “Ethereum Dominance” Harder to Measure

This may be the most important measurement problem in the entire discussion. Ethereum increasingly operates as an ecosystem rather than a single execution environment.

A user can:

1. Hold an asset associated with Ethereum.
2. Bridge it to an L2.
3. Trade on the L2.
4. Provide liquidity on the L2.
5. Use an application deployed on the L2.
6. Eventually settle activity through infrastructure connected to Ethereum.

From the user's perspective, this can feel like one Ethereum ecosystem. From a TVL dashboard's perspective, the capital may be attributed to a different chain.

Ethereum L1 vs. Ethereum Ecosystem

This creates two different questions:

Question 1: How much DeFi capital is locked directly on Ethereum?

Question 2: How much DeFi activity exists across the broader Ethereum-connected ecosystem?

Those are not the same measurement.

Base makes the distinction particularly obvious.

If Base holds billions of dollars in DeFi liquidity, that capital contributes to the broader Ethereum scaling ecosystem without appearing inside Ethereum L1's standalone TVL number. Current Base data also shows about $19.4 billion in bridged TVL, compared with roughly $5.7 billion of native TVL, highlighting how much broader the ecosystem's capital footprint can be than a simple native-TVL figure suggests.

Should Ethereum's Dominance Include Its L2s?

This is where the definition of Ethereum DeFi dominance becomes complicated.

Consider an ecosystem consisting of:

• Ethereum L1
• Base
• Arbitrum
• Optimism
• Other Ethereum L2s

If all of them are counted separately, Ethereum's L1 dominance can appear to shrink.

If they are aggregated into one Ethereum ecosystem, Ethereum's economic footprint looks much larger.

Neither measurement is automatically wrong.

They answer different questions.

Ethereum Is Still Holding a Large Amount of Stablecoin Liquidity

TVL also fails to capture another important part of the DeFi economy: stablecoins that are economically useful without being locked inside a protocol.

As of September 2026, total stablecoin market capitalization is around $305 billion. USDT accounts for roughly $183 billion, while USDC represents approximately $74 billion.

That liquidity matters because stablecoins function as:

• Trading assets
• DeFi collateral
• Settlement assets
• Treasury instruments
• Payment assets
• Liquidity for decentralized exchanges
• Bridges between different blockchain ecosystems

But not every stablecoin is deposited into Aave, a DEX pool or another DeFi protocol.

A USDC token sitting in a wallet is not counted the same way as USDC deposited into a lending market. Yet both can be economically useful. That leads to another important distinction:

TVL does not equal all economically useful liquidity.

This matters when interpreting Ethereum DeFi dominance because a decline in protocol TVL does not necessarily mean that Ethereum's stablecoin infrastructure has become irrelevant.

DEX Activity Tells a Different Story From TVL

TVL measures capital. DEX volume measures activity. Those two metrics can move in completely different directions.

What TVL Measures

TVL generally reflects:

• Assets deposited into protocols
• Liquidity supplied to markets
• Lending collateral
• Capital committed to applications
• Assets held within DeFi contracts

What DEX Volume Measures

DEX volume captures:

• Trading activity
• Token swaps
• Liquidity turnover
• Market demand
• Capital movement between assets

This distinction is critical.

A chain can have relatively modest TVL but extremely high trading volume.

Another chain can hold enormous amounts of capital while generating considerably less trading activity.

Current DeFiLlama figures show the difference clearly. Ethereum currently records roughly $1.3 billion in 24-hour DEX volume and $36.9 billion over 30 days, while Solana records approximately $2.7 billion over 24 hours and $68.4 billion over 30 days. Base also records roughly $900 million in 24-hour DEX volume and $25.1 billion over 30 days.

That does not prove Ethereum is losing users.

It shows that TVL alone cannot describe where DeFi activity is happening.

For Ethereum DeFi dominance, that is a crucial distinction.

Is Ethereum Actually Losing Users Or Is DeFi Becoming a Multi-Chain?

There are two competing interpretations.

Argument 1: Ethereum Is Losing Some Activity

There is genuine evidence for this interpretation.

Ethereum faces competition from networks offering:

• Cheaper transactions
• Faster execution
• Specialized trading environments
• Alternative application ecosystems
• Different liquidity incentives
• Large retail user bases

Its declining share of DeFi TVL is therefore not meaningless.

Some activity and liquidity have clearly developed elsewhere.

Argument 2: DeFi Is Fragmenting

The alternative explanation is that users are not necessarily choosing one blockchain and permanently abandoning another.

Instead, they increasingly use multiple ecosystems.

A user might:

• Hold ETH on Ethereum.
• Move stablecoins to an L2.
• Trade on Base.
• Use Solana for another market.
• Keep assets on a centralized exchange.
• Return to Ethereum for another application.

The user's DeFi footprint becomes multi-chain.

That changes the competitive model.

The market may be shifting from:

Ethereum → Everything Else

to:

Ethereum + L2s + Alternative L1s + Cross-Chain Liquidity

That is a much more significant structural development than a simple leaderboard change.

The New DeFi Competition Is About Where Activity Happens, Not Just Where Capital Is Locked

Ethereum DeFi dominance becomes much harder to define once multiple measurements are considered.

Each metric answers a different question.

A network can rank highly in one category and lower in another.

That is why there is no single metric capable of measuring DeFi dominance perfectly anymore.

The Practical Interpretation

If Ethereum leads TVL but another chain leads DEX volume, neither metric is necessarily wrong.

They are measuring different aspects of the market.

The more sophisticated question is therefore:

Which blockchain is capturing the most economically meaningful activity across liquidity, trading, users, fees and settlement?

That is much harder to answer than simply ranking chains by TVL.

Ethereum's Falling Dominance May Actually Be Evidence of DeFi Maturing

This is the less obvious interpretation.

Early DeFi was heavily concentrated on Ethereum because Ethereum had several advantages at the same time:

• The largest smart-contract ecosystem
• Established DeFi protocols
• Deep liquidity
• Mature developer infrastructure
• Widely adopted token standards
• Strong wallet support
• Established stablecoin infrastructure

As the industry matured, competitors gained enough infrastructure and liquidity to specialize.

That produced different ecosystem profiles.

This means falling Ethereum DeFi dominance does not automatically represent technological failure.

It can also represent market specialization.

Ethereum no longer needs to be the only place where DeFi happens for the overall DeFi economy to become larger.

What Would Actually Prove Ethereum Is Losing DeFi Relevance?

The article should not become an argument that Ethereum cannot lose its position.

It can.

But the evidence would need to be broader than a declining percentage of TVL.

Stronger Evidence of Structural Decline

A much more convincing bearish case would involve several indicators moving together:

• Ethereum's absolute TVL falling persistently
• Stablecoin liquidity leaving Ethereum
• DEX activity consistently migrating elsewhere
• Developers increasingly choosing competing ecosystems
• Major DeFi protocols reducing Ethereum exposure
• Ethereum L2 growth failing to compensate for L1 weakness
• Lower protocol revenue and fees
• Declining economic activity alongside declining liquidity

The strongest warning would be simultaneous deterioration in both capital and activity.

What Would Not Be Enough?

A falling percentage of total DeFi TVL does not automatically mean Ethereum is losing its underlying strength. If Ethereum’s TVL remains substantial while the broader DeFi economy expands much faster across competing networks, its market share can decline even as its own ecosystem remains economically significant. This distinction is especially important when comparing Ethereum’s role across applications ranging from decentralized exchanges to a crypto casino, where liquidity, transaction activity, and user demand may increasingly be distributed across multiple chains. That distinction should remain central to the Ethereum DeFi dominance discussion.

The 63.5% to 53–54% Drop Needs to Be Read Differently

Return to the study case.

The raw story is simple:

63.5% → ~53–54%

That looks bearish.

But the fuller picture is more complicated.

Ethereum still has:

• Significant absolute DeFi liquidity
• Deep protocol liquidity
• Major stablecoin infrastructure
• A large developer ecosystem
• An expanding L2 ecosystem
• Significant DEX activity
• Established settlement infrastructure

At the same time, competing ecosystems have captured a much larger share of the overall DeFi economy.

Both statements can be true.

Ethereum can lose market share while remaining one of the most important platforms in DeFi.

The current data reinforces why activity needs to be separated from TVL. Ethereum remains among the largest DEX venues, while Solana, BNB Chain and Base are also processing substantial trading volumes.

The more accurate description is therefore:

Ethereum's dominance is declining, but its role may be changing from being synonymous with DeFi to being a core component of a much larger multi-chain DeFi economy.

What to Watch Next for Ethereum DeFi Dominance

The next phase should be evaluated using several indicators rather than one percentage.

1. Ethereum Absolute TVL

Is Ethereum continuing to attract and retain capital?

2. Ethereum Stablecoin Liquidity

Are stablecoins remaining within Ethereum's broader ecosystem?

3. DEX Volume

Is trading activity stabilizing, growing or consistently migrating elsewhere?

4. L2 Growth

Are Base, Arbitrum, Optimism and other Ethereum L2s expanding the ecosystem?

5. Fees and Revenue

Are users generating meaningful economic demand?

6. Developer Activity

Are new protocols still choosing Ethereum and its surrounding infrastructure?

7. Cross-Chain Liquidity

Are users becoming more multi-chain rather than simply switching chains?

This framework provides a much better way to evaluate Ethereum DeFi dominance than asking whether Ethereum has regained a particular percentage of TVL.

The Bigger Lesson: Dominance Is Becoming a Poorer Proxy for Importance

The DeFi market has changed.

When one blockchain hosted most of the major protocols and liquidity, TVL dominance was a relatively straightforward indicator.

That is no longer the case.

Today, capital can move across:

• L1s
• L2s
• Bridges
• Stablecoins
• DEXs
• Lending markets
• Perpetual exchanges
• Cross-chain applications

Economic activity can also be split between execution environments while remaining connected through common liquidity and infrastructure. That makes blockchain dominance increasingly multidimensional.

Ethereum can lose TVL share while maintaining strong influence over liquidity, stablecoins, developers, settlement and L2 activity. Likewise, another chain can dominate trading volume without replacing Ethereum across the entire DeFi stack.
