Quick Breakdown
- Ethereum remains the default hub for DeFi and NFTs due to deep liquidity ($54.6B TVL), blue-chip protocols, strong developer standards (EVM, ERC-20/721), and institutional trust, even as competition grows.
- Layer-2 solutions strengthen Ethereum’s position by cutting fees 90%+ and improving usability, allowing it to scale while keeping security and liquidity anchored to its base layer.
- Rivals like Solana and BNB Chain lead in speed and retail activity, but Ethereum continues to dominate in security, economic finality, and settlement value, positioning it as the financial backbone of the modular crypto ecosystem.
When we say Ethereum is the “default choice” for DeFi and NFTs, it’s about it being the go-to network that most people, projects, and investors naturally turn to. Think of it like the city everyone visits first because it has the best roads, reliable services, and plenty of people already living there.
For Ethereum, those “roads” are liquidity, the “services” are the tools and developer infrastructure, and the “people” are the users and communities. DeFi protocols, NFT marketplaces, and wallets were built first on Ethereum, meaning a huge amount of assets, user trust, and developer knowledge is concentrated there.
But things are changing. Layer 2s like Optimism and Arbitrum make Ethereum faster and cheaper, and networks like Solana are growing with speed and low fees. Today, many projects exist across multiple chains, so being the default doesn’t automatically mean being the only choice.
Ethereum’s Position in DeFi Today
Ethereum still holds a strong position in DeFi, largely because of the depth of its capital and liquidity. Its Total Value Locked (TVL) stands at $54.19 billion, higher than most other chains. It means more money is available for trading, lending, and staking, making it easier for users to enter and exit positions without causing big price swings. This is something both regular users and larger investors care about.
A big reason for this dominance is the presence of blue-chip DeFi protocols like Uniswap, Aave, Maker, and Lido. These platforms have built trust over the years and handle billions in transactions daily. They act as anchors, drawing both users and capital to Ethereum. New projects often launch alongside these protocols or integrate with them, further strengthening Ethereum’s network effect.
Institutional investors and whales also prefer Ethereum-based DeFi. These players look for stability, liquidity, and reliable infrastructure, areas where Ethereum still leads. Big capital moving in and out of Ethereum projects helps maintain high liquidity, which in turn keeps transaction costs predictable and trading efficient.
Overall, liquidity still clusters around Ethereum because it combines history, trust, and scale. Even with new chains growing fast, the largest pools of capital and the most trusted protocols remain on Ethereum, making it the first stop for anyone serious about DeFi.
Ethereum and the NFT Market: Still the Centre of Gravity?
Ethereum still holds the most weight in the NFT world, especially for high‑value collections and cultural icons. Many of the historically important NFT projects, like CryptoPunks and Pudgy Penguins, were created on Ethereum and continue to be traded there. These blue‑chip collections give Ethereum economic and cultural pull that newer chains haven’t matched in full scale.
When looking at where NFT trading happens, Ethereum still accounts for a large share of activity. Recent data shows it captured around 62% of NFT trade volume, which remains higher than competitors like Solana or Bitcoin Ordinals. Major marketplaces like OpenSea continue to lead overall trading volume, reinforcing Ethereum’s role as the main discovery layer for iconic collections and broad market liquidity.
Ethereum’s NFTs also carry cultural weight. Collectors, institutions, and long‑term holders often see assets on Ethereum as more established or “serious.” Even as speculative hype has faded since the peak years, trading among well‑known collections and serious buyers often centers back on the Ethereum ecosystem.
The Layer-2 Effect: Ethereum Without Ethereum’s Fees
Ethereum’s base layer (Layer 1) has long been criticized for high gas fees. Layer‑2 solutions, like Arbitrum, Optimism, Base, and zkSync, were created to fix that by processing most work off the main chain and then settling results back on Ethereum. This dramatically lowers costs while keeping Ethereum’s security.
On these Layer‑2 networks, transaction fees are often 90%+ lower than on the Ethereum mainnet. Users now pay just a few cents (or sometimes fractions of a cent) for swaps, transfers, or NFT actions. That shift makes DeFi and NFTs more usable for regular activity and small traders who once avoided Ethereum because fees made everyday transactions too expensive.
These L2s aren’t separate ecosystems in the way that entirely different chains (like Solana) are. They inherit Ethereum’s security model while operating as extensions of it. That means assets and activity still “live” within the broader Ethereum framework, not on a completely new blockchain. It helps developers reuse existing tools and smart contracts with minimal changes, and keeps liquidity and composability connected to Ethereum’s core ecosystem.
Different Layer‑2s bring slightly different benefits. Arbitrum has become a leading rollup with strong DeFi usage and $2.1 billion TVL. Optimism focuses on broad cross‑chain compatibility and long‑term infrastructure. Base, backed by Coinbase, has attracted lots of retail users because it’s easy to access. zkSync and other zk‑rollups use cryptographic proofs for near‑instant settlement and very low fees, although ecosystems may still be smaller than optimistic rollups.
For DeFi usability, these lower costs mean more activity happens where transactions are cheap, reducing friction for borrowing, trading, and yield farming. For NFTs, cheaper minting and trading make it easier for new creators and collectors to participate without high gas bills. L2s help Ethereum maintain its role as a hub for dApps by solving one of its biggest problems: cost.
Developer Ecosystem and Network Effects
One of the reasons developers still choose Ethereum first is the maturity and reach of its ecosystem. Ethereum’s tooling, documentation, and technical standards have been built up for years, making it easier for developers to start, build, test, and deploy their applications.
The Ethereum Virtual Machine (EVM) is the engine that runs smart contracts in a consistent way across Ethereum and many other chains. This means developers work with familiar environments and languages like Solidity, and their skills transfer directly across many networks without starting from scratch.
Ethereum’s standards, such as ERC‑20 for tokens and ERC‑721 for NFTs, have become widely accepted building blocks across the entire blockchain space. These standards reduce uncertainty because developers and users know how they behave and how tools like wallets and marketplaces will support them.

Developers use Ethereum first because the ecosystem already exists at scale. Thousands of tools and frameworks (like Hardhat, Remix, OpenZeppelin, and MetaMask) are designed around Ethereum, with deep documentation and large communities ready to answer questions or share code. This lowers barriers for newcomers and experienced builders alike.
Another big advantage is composability. On Ethereum, smart contracts are designed to interact easily with one another, like building blocks. A lending protocol can reference an existing price oracle, a wallet can pull tokens from many contracts, and an NFT marketplace can integrate with DeFi vaults, all without special bridges or adapters.
This accelerates innovation and encourages more complex applications because developers can reuse existing, tested contracts rather than reinvent basic components.
Competition Check: Where Rivals Are Winning
Even though Ethereum is still a major force in DeFi and NFTs, several rival blockchains have made real gains in areas where Ethereum is weaker.
Solana’s speed and UX appeal
Solana’s biggest strength is raw performance. It can handle over 65,000 transactions per second, far more than Ethereum’s base layer and with lower costs. In 2025, Solana reportedly processed $2.39 billion in dApp revenues and saw strong decentralized exchange revenue thanks to upgrades that reduced latency to under 400 ms and cut fees significantly.
This speed and low cost have made Solana attractive, especially for users who want fast swaps, cheap NFT mints, and frequent trading. For many retail users and traders, Solana feels snappy and affordable compared with Ethereum’s mainnet fees (even after Layer‑2 improvements). That user‑experience edge has helped Solana stay near the top in ecosystem attention and activity.
Other chains: BNB chain, Avalanche, and more
BNB Chain has also risen fast by combining low fees, fast block times, and massive user numbers. In 2025 and into 2026, BNB Chain reportedly passed Solana and Ethereum with 4.32M in daily active wallets, driven by cheap transactions and broad ecosystem support.
Avalanche is another contender that competes on performance and cost, with sub‑second finality and low fees on its smart contract chains. These alternatives show that simple user experience and low cost are strong magnets for retail activity, especially in markets where cheap transactions matter more than deep liquidity or long‑term trust.
Areas where Ethereum is genuinely losing ground
There are some real areas where Ethereum is losing ground:
- Retail UX and activity: BNB Chain and Solana have grown larger in daily wallet activity, powered by easier onboarding and lower costs.
- Transaction throughput & speed: Raw TPS and fast finality metrics heavily favour Solana and some other chains over Ethereum’s base layer.
- Attention and mindshare: In recent rankings, Solana, Base, and other ecosystems collectively earned more global attention than Ethereum alone.
Security, Trust, and Economic Finality
One of the biggest strengths Ethereum still holds in 2026 is security and trust. For high-value financial systems like DeFi, the base layer’s safety matters more than speed or low fees. Developers, institutions, and large holders look for a blockchain where money and smart contracts are extremely hard to tamper with, and that’s where Ethereum stands out.
Ethereum uses a Proof-of-Stake (PoS) consensus system, where validators lock up (or stake) ETH to help secure the network. If a validator misbehaves, they risk losing their stake. This creates strong economic incentives for honest behaviour and makes it extremely expensive for bad actors to try to attack the network. Reversing finalized transactions would require controlling over two-thirds of all staked ETH and risk massive loss through slashing, which is intentionally punitive.
This mechanism leads to what’s known as economic finality: once a transaction is finalized, it’s nearly impossible to alter without unbearable financial cost. That matters a lot for DeFi protocols managing billions of dollars. The harder it is for attackers to change blocks or manipulate data, the more confidence users and institutions have in leaving their funds on that chain.
For high-value DeFi, this trade-off between speed and security is worth it. A slower settlement that’s highly trusted beats a faster system that might be easier to exploit. Newer blockchains and some alternative consensus models can offer quicker confirmations or immediate finality, but they often do so with fewer validators or more centralized structures, which reduces the difficulty of attack. Ethereum’s deep validator set and economic cost model make real attacks prohibitively expensive by comparison.
Is Ethereum Still the Default or the Settlement Layer?
By 2026, the real question may not be whether Ethereum is the default app chain for DeFi and NFTs but whether it has become the settlement layer for a broader modular system.
Ethereum’s base layer now focuses less on handling every transaction directly and more on securing value and settling activity that happens elsewhere. After the shift to Proof-of-Stake and major upgrades like EIP-4844 (proto-danksharding), Ethereum reduced data costs for Layer-2 rollups and reinforced its long-term scaling roadmap. The goal is to let Layer-2s handle execution and user activity, while Ethereum secures and finalizes the results.
This reframes Ethereum’s role. It may not win on raw transaction speed or cheapest fees at the base layer. Instead, it acts as the economic anchor. Billions of dollars in DeFi, staking, and tokenized assets ultimately rely on Ethereum’s security guarantees. In this sense, Ethereum is less of a consumer app chain and more of a financial backbone.
In a modular future, “default” does not necessarily mean “where every user interacts.” It may mean:
- Where liquidity ultimately settles
- Where high-value assets are secured
- Where developers anchor their rollups
- Where institutions feel comfortable storing capital
Under this model, Ethereum doesn’t need to dominate daily transactions to remain the default. If the most serious value eventually settles on Ethereum, even if users interact through Arbitrum, Base, or other networks, then Ethereum still sits at the center of the system.
Final Take: Default by Design, Not by Convenience
Ethereum remains the default because of liquidity, security, and infrastructure, not because it is the cheapest or fastest. It leads in Total Value Locked, developer tooling, and institutional trust. At the same time, it is losing ground in retail user experience, speed, and low-cost activity, where chains like Solana and BNB Chain compete more effectively.
For Ethereum to lose its default status, a rival would need to match its capital depth, security model, developer ecosystem, and long-term reliability, all at scale. So far, no chain has replaced it across all these areas. Until that changes, Ethereum is likely to remain the default foundation for DeFi and high-value NFTs, even in a multichain system.
