The “Ethereum killer” narrative is one of crypto’s most recycled stories. In 2017, EOS raised $4 billion, promising to make Ethereum obsolete. Cardano, Tezos, and Polkadot followed with similar arguments. In 2021, it was Avalanche, BSC, and Terra. None of them replaced Ethereum.
And yet the question keeps returning because Solana is making a more credible case than anyone has before.
We’ll understand in this article why Ethereum has survived every challenge so far, and whether that’s still true today, requires looking past price performance and into what each network actually does.
Why Has Ethereum Survived Every “Killer” So Far?
Taking a good look at the pattern across failed challengers shows something consistent.
Each new Layer-1 arrived with a genuine technical advantage (higher throughput, lower fees, faster finality) and used Ethereum’s congestion as its marketing pitch.
Each captured a wave of users and capital during the bull run that coincided with its launch. And each saw that capital evaporate when the cycle turned, leaving ecosystems that looked impressive on paper but had little durable activity underneath.
What they couldn’t replicate was Ethereum’s liquidity and composability. By the time serious challengers emerged, Ethereum already hosted the protocols that mattered (Uniswap, Aave, Compound, MakerDAO).
A competing chain could offer faster transactions, but it couldn’t offer Uniswap’s liquidity depth or Aave’s audited lending infrastructure on day one because building that from scratch takes years, not months.
The developer ecosystem also reinforced this. Ethereum’s Solidity is the most widely known smart contract language in crypto. Its tooling, documentation, and auditing infrastructure are unmatched. Switching a team to a new chain means retraining, rebuilding, and accepting a smaller talent pool. For most serious projects, the switching cost is higher than the performance gain.
Is Solana Actually Different From Previous Ethereum Killers?
The honest answer is yes. Solana is a more credible threat than anything that came before it. The gap between it and previous challengers is significant.
By raw user activity, Solana has already overtaken Ethereum on its base layer.
In Q1 2025, Solana averaged 3.2 million daily active wallets versus Ethereum’s 430,000. Transaction throughput on Solana reaches 65,000 TPS against Ethereum mainnet’s 30 TPS. Average fees sit at $0.00025 per transaction versus roughly $2.93 on Ethereum mainnet. For high-frequency, low-value activity, trading, gaming, payments, and minting, Solana is objectively superior at the user experience level.
The financial metrics back this up. Solana’s DEX volume hit $1.5 trillion in 2025, up 57% year-over-year. Seven Solana-based applications each generated over $100 million in revenue. Its stablecoin supply grew by over 170% in 2025, reaching approximately $15.65 billion; a sign that real capital is flowing through the network, not just speculative tokens.
Solana even attracted $1.02 billion in net inflows to its spot ETFs in the latter half of 2025, despite entering the ETF market later than Ethereum.
What makes Solana’s challenge structurally different is that it has survived a severe bear market and come out stronger. The FTX collapse in 2022 devastated the Solana ecosystem as FTX and Alameda were among its largest backers.
Solana’s token fell by over 95% from its peak. Most observers wrote it off. Instead, the developer community rebuilt, the ecosystem diversified, and Solana emerged from 2023 with more credibility, not less. That resilience marks it as a different class of competitor than EOS or Terra.
Where Does Ethereum Still Lead?
Despite Solana’s gains, Ethereum retains advantages that are difficult to close quickly.
Capital depth is the most important. Ethereum’s DeFi TVL stood at approximately $92 billion as of early 2026, which is more than nine times Solana’s $9.85 billion. Ethereum ETFs and institutional reserves hold over $35 billion in ETH. On-chain real-world asset issuance exceeded $12 billion in 2025. These are institutions with long time horizons, compliance requirements, and high switching costs.
Still, Ethereum holds roughly 60% of all DeFi TVL, down from a high of over 80% but still commanding majority control of the sector’s most valuable capital.
The developer base remains substantially larger on its own. Ethereum reported approximately 32,000 active developers in 2025, which is nearly double Solana’s figure, even as Solana’s developer count grew 42% year-over-year. More developers means more audited protocols, more tooling, more security research, and more institutional trust in the code running on-chain.
Stablecoin settlement also tells a similar story. Ethereum settled $18.8 trillion in stablecoin transactions in 2025. Together, Ethereum and Tron account for 81% of all circulating stablecoins on the entire blockchain. Solana’s stablecoin market has grown impressively, but Ethereum remains the settlement backbone for crypto’s largest financial flows.
And Ethereum’s Layer-2 scaling has addressed its most cited weakness more effectively than expected. After the Dencun upgrade in March 2024, transaction costs on Layer-2 networks dropped roughly 95%. Ethereum’s L2 ecosystem processed over 5,600 TPS on average in 2025, with daily peaks reaching 1.74 million transactions. When L2 activity is included, Ethereum’s effective throughput exceeds Solana’s base-layer TPS, the comparison most “Ethereum is slow” arguments rely on.
What About Other Challengers: Sui, Aptos, Avalanche?
Solana is the only current challenger with a realistic path to meaningful competition with Ethereum. The others occupy niches.
Avalanche’s TVL sits at approximately $6.4 billion, and it has found genuine product-market fit in gaming and enterprise subnets, but it hasn’t threatened Ethereum’s core DeFi dominance.
But, Sui and Aptos (the two high-profile launches of 2022–2023) have generated strong technical benchmarks (Sui and Aptos both support 100+ TPS natively) and raised significant capital, but their ecosystems remain early-stage.
Combined, they represent a small fraction of Ethereum’s TVL and developer count. BNB Chain still leads in raw DEX trading volume at certain points in 2025, but its centralization and association with Binance limit its appeal.
Avalanche serves gaming. BNB Chain serves retail trading in Asian markets. Tron dominates stablecoin transfers in emerging economies. None of them replaced Ethereum because none of them needed to because the market was fragmented by use case rather than collapsing into a single winner.
Can Solana Replace Ethereum?
Not in the near term, but the question itself may be the wrong framing.
The more accurate picture emerging from 2025 data is that Ethereum and Solana are diverging into complementary roles rather than competing for the same users.
Ethereum led a bigger institutional adoption, stablecoin settlements, and DeFi TVL. Solana excelled in user growth, trading volume, app revenue, and low fees, driving retail usage. These aren’t the same market. One is a settlement and custody layer for large capital, and the other is a high-throughput execution layer for active users.
For Solana to genuinely replace Ethereum, it would need to capture institutional trust at scale, the kind that comes from years of uptime, deep auditing culture, and regulatory familiarity. That takes time.
Ethereum’s institutional lead is measured in billions of dollars of ETF assets, $12 billion in tokenized real-world assets, and $18.8 trillion in stablecoin settlement. Closing that gap settles more on a trust problem, and trust accrues slowly.
What’s more likely over the next several years is continued market share erosion at the edges: Solana taking retail activity, gaming, and high-frequency DeFi, while Ethereum consolidates its position as the institutional and high-value settlement layer. That’s a genuinely threatening trajectory for Ethereum’s long-term fee revenue, but it’s not a replacement.
The Ethereum killers narrative has been wrong every time, though Solana is the first challenger that might prove it partially right.
