Executive Summary: The Current DeFi Leadership Battle
Short answer: As of now, Ethereum continues to dominate DeFi through total value locked (TVL) and institutional trust in October 2025. Meanwhile, Solana shines as the retail-focused chain—delivering faster transactions and lower costs, frequently topping daily DEX volumes despite having shallower liquidity pools.
Key Takeaways for Busy Readers
First and foremost, Ethereum commands about $94 billion in TVL compared to Solana’s $12.6 billion. In other words, this represents roughly 7-8× more capital locked in DeFi protocols. However, Solana has repeatedly exceeded Ethereum in daily and monthly DEX volumes during 2024-2025 memecoin surges through platforms like Raydium and Jupiter.
Additionally, transaction fees differ dramatically between the two chains. For instance, Solana maintains sub-cent costs while Ethereum mainnet can spike. Nevertheless, Layer 2 solutions like Arbitrum, Base, and Optimism now offer penny-level fees after the Dencun upgrade.
Furthermore, Ethereum operates with over 1 million validators without multi-hour outages. In contrast, Solana experienced a 5-hour chain halt on February 6, 2024, and continues to strengthen infrastructure with the upcoming Firedancer client.
Understanding What DeFi Leadership Really Means in 2025
The Multiple Dimensions of Blockchain Success
To clarify, DeFi leadership analysis requires looking at several key factors rather than just one metric. If you’re interested in how these chains compare across broader metrics, check out our detailed Ethereum vs Solana vs Polygon vs TON chain metrics comparison. Specifically, critical performance indicators include:
Critical Performance Indicators:
- Liquidity depth (TVL): Notably, this impacts slippage, credit availability, and derivatives markets
- Throughput & transaction costs: Similarly, this affects user experience for swaps, perpetuals, and market making
- Reliability & decentralization: Moreover, this covers network uptime and resistance to capture
- Ecosystem momentum: Finally, this includes developer activity, protocol launches, and real-world asset (RWA) integrations
As a result, on composite scoring, Ethereum leads in overall DeFi infrastructure. On the other hand, Solana dominates retail user experience and volume spikes.
Ethereum: The Institutional DeFi Standard
Why Liquidity Depth Matters Most
To begin with, Ethereum DeFi protocols hold about $94 billion in TVL across Layer 1 and related applications according to DefiLlama. Consequently, this liquidity advantage translates to reduced slippage on large transactions. Furthermore, it creates deeper money markets for lending protocols like Aave and Compound.

How the Dencun Upgrade Changed Everything
The Technical Breakthrough
In March 2024, the Dencun upgrade (EIP-4844) introduced blob data structures for rollups. As a result, this collapsed Layer 2 transaction fees to cent-level pricing while keeping mainnet security intact. Subsequently, users can now access:
- Arbitrum: An optimistic rollup with an extensive DeFi ecosystem
- Base: A Coinbase-backed Layer 2 with consumer focus
- Optimism: A governance-focused scaling solution
- ZK-rollups: Including zkSync, Polygon zkEVM, and Starknet
The Impact on Users
Because of these changes, most Ethereum DeFi users now pay only a few cents per transaction. Therefore, this makes Ethereum competitive with Solana on cost while maintaining superior security.
Security That Institutions Trust
Network Resilience
Above all, Ethereum maintains operational continuity without multi-hour chain halts. In fact, it’s supported by about 1.0-1.1 million validators ensuring decentralization according to Beaconcha.in. Moreover, this resilience has been proven across multiple market cycles and network stress tests.
Real-World Institutional Adoption
Major tokenization projects like BlackRock’s BUIDL fund operate on Ethereum. Additionally, many real-world asset funds and pilots launch on the network first. For example, traditional finance integration includes:
- Tokenized treasuries: Franklin Templeton, WisdomTree
- Securities settlement: DTCC pilot programs
- Corporate blockchain: JPMorgan’s Onyx, Visa’s stablecoin initiatives
The Trade-off: Despite these advantages, Ethereum mainnet fees remain volatile during congestion. Also, Layer 2 fragmentation splits liquidity across multiple rollups, which can complicate the user experience.
Solana: The High-Speed Retail DeFi Champion
What Makes Solana Different
Lightning-Fast Performance
First of all, Solana delivers sub-second transaction finality with fees under $0.01. In particular, this is perfect for frequent swaps, memecoin trading, and high-speed strategies. Unlike Ethereum’s modular approach, the monolithic architecture processes everything on a single layer. To understand why Solana continues rising despite Ethereum’s dominance, read our analysis on Solana and TON: why these chains are rising but still can’t kill Ethereum.
When Solana Beats Ethereum in Volume
The DEX Revolution
During late 2024 and 2025, Solana DEXs periodically beat Uniswap in monthly volume and weekly fees. Specifically, this happened during memecoin explosions on platforms like:
- Jupiter: The leading DEX aggregator
- Raydium: A popular automated market maker (AMM)
- Marinade Finance: The top liquid staking platform
- Drift Protocol: For perpetuals trading
As a matter of fact, this demonstrates Solana’s capacity to dominate transaction flow despite lower TVL according to Messari data.
How Solana Is Getting More Reliable
Learning from Downtime
After the February 6, 2024 outage, Solana’s ecosystem focused intensely on reliability efforts. Most importantly, Jump Crypto’s Firedancer client targets massive throughput improvements. In testing, it has shown about 1 million TPS capacity, which would significantly enhance network stability.
The Current State of Development
Nevertheless, these improvements are still in progress. Meanwhile, the network continues operating with over 1000 validators as tracked by Solana Compass.
Understanding Solana’s Liquidity Gap
The Numbers Don’t Lie
Despite impressive transaction volumes, Solana’s TVL stands at about $12.6 billion according to DefiLlama. In comparison, this is much smaller than Ethereum’s liquidity pools. Therefore, collateral depth still trails by substantial margins.
The Bottom Line: Lightning-fast user experience doesn’t equal deep composable credit or derivatives infrastructure. In other words, institutional-scale DeFi operations still require Ethereum’s deeper liquidity.

Clearing Up Common Myths About DeFi
Myth #1: Solana Has $30B in TVL
The Reality: Mainstream metrics from DefiLlama show Solana TVL at about $12-13 billion. However, some communities circulate inflated claims of $30 billion. In fact, different tracking methods (including staked assets, bridged tokens) create these discrepancies.
Myth #2: Arbitrum TVL Is Wrong
What’s Really Happening: DefiLlama lists Arbitrum at roughly $3.7 billion native TVL. However, it shows about $11.4 billion in bridged TVL. As a result, various dashboards report different figures based on their counting methods.
Myth #3: Ethereum Does 100k+ TPS Now
The Truth: While post-Dencun upgrades greatly increased throughput and reduced costs, actual transactions-per-second vary by rollup and workload. Therefore, six-figure TPS claims represent theoretical capacity rather than daily averages.
The Final Verdict: Who Actually Leads DeFi Right Now?
Ethereum’s Continued Dominance
In summary, Ethereum keeps DeFi leadership through superior TVL, proven security, protocol variety, and institutional adoption. You can verify current TVL data at DefiLlama and validator counts at Beaconcha.in.

Solana’s Growing Influence
On the other hand, Solana leads in retail user experience and burst transaction volumes. Moreover, it drives innovation through competitive pressure, which benefits the entire DeFi ecosystem.
Simple Analogy: If DeFi were athletics, Ethereum runs the marathon (steady, deep, reliable). Meanwhile, Solana sprints (explosive, smooth, engaging). Therefore, choose based on your specific use case, not tribal loyalty.
