In the rapidly evolving world of decentralized finance (DeFi), platform choice can make or break a project. Kain Warwick, founder of the prominent DeFi protocol Synthetix, recently shared insights into why his team ultimately chose Ethereum over alternative smart contract platforms like EOS—a decision rooted in long-term sustainability, developer momentum, and robust ecosystem support.
This deep dive explores the core reasons behind Ethereum’s dominance in the DeFi space, backed by real-world development challenges and strategic foresight from one of the industry’s leading innovators.
Why Ethereum Won: Developer Experience and Ecosystem Maturity
When Synthetix was in its early planning stages, EOS emerged as a potential candidate for deployment. At the time, EOS promised high throughput and low transaction fees—features that seemed ideal for a scalable DeFi application.
However, after months of technical evaluation by Chief Technology Officer Justin Moses, the team concluded that EOS lacked mature development tools and infrastructure. Building a complex financial system like Synthetix would have required reconstructing foundational tooling from scratch—essentially reinventing what Ethereum already offered.

The quality and accessibility of Ethereum’s developer tools stood out as unmatched. From widely adopted frameworks like Truffle and Hardhat, to battle-tested testing libraries and debuggers, Ethereum provides a comprehensive suite that accelerates secure smart contract development.
As Warwick emphasized, "The tools on Ethereum are simply in a league of their own." For a project handling millions in collateralized value, reliability isn’t optional—it’s mandatory.
The Power of Network Effects in Blockchain
One of Ethereum’s most significant advantages isn’t technical—it’s social. The platform benefits from powerful network effects, where growing adoption attracts more developers, which in turn draws more users and capital, reinforcing the cycle.
According to a report by Electric Capital, nearly 25% of open-source blockchain developers actively contribute to Ethereum-based projects. This influx of talent ensures continuous innovation, rigorous security audits, and rapid response to emerging threats.
Warwick noted that this concentration of skilled developers creates a self-reinforcing advantage:
“Capital follows competence. No other platform can match Ethereum’s ability to attract both top-tier builders and institutional-grade funding.”
Even as new Layer 1 blockchains emerge with claims of superior speed or lower costs, they struggle to replicate the depth and breadth of Ethereum’s developer community. That gap isn’t closing—it’s widening.
Capital Allocation Favors Ethereum-Based Projects
DeFi is growing at an exponential rate, with total value locked (TVL) surpassing tens of billions across various protocols. But where is this capital flowing? Overwhelmingly, into Ethereum-native applications.
Platforms like MakerDAO, Compound, and Aave—all built on Ethereum—continue to dominate lending and borrowing markets. Investors recognize that while alternative chains may offer short-term gains in performance metrics, Ethereum offers something more valuable: proven security, composability, and trust.
Warwick pointed out:
“Investors are allocating the majority of their DeFi capital to Ethereum-based projects because they know the ecosystem has withstood stress tests, market crashes, and flash loan attacks—and it’s still standing.”
This confidence translates into sustained funding rounds, deeper liquidity pools, and stronger partnerships—all contributing to Ethereum’s entrenched position.

User Choice Is Shifting: From Chains to Applications
Looking ahead, Warwick believes the competition won’t be between blockchains—but between applications themselves.
“Users don’t care about consensus mechanisms or gas fees—they care about functionality, user experience, and yield. Their choice isn’t between Ethereum and EOS; it’s between using Compound or MakerDAO.”
This shift mirrors trends seen in other tech ecosystems. Just as consumers choose apps on iOS or Android without worrying about the underlying OS architecture, future crypto users will prioritize seamless interfaces and reliable services over chain-specific features.
While early-mover advantage often fades in traditional tech (e.g., Yahoo vs. Google), blockchain networks benefit from strong immutability and governance models that make migration costly and risky. Once a protocol gains traction on a chain like Ethereum, switching becomes impractical.
Ethereum’s Long-Term Resilience
Despite ongoing debates about scalability and transaction costs, Ethereum continues to lead in developer activity and institutional adoption. A previous analysis highlighted that 92.3% of blockchain developers still consider Ethereum their primary platform for building decentralized applications.
Even with the rise of Layer 2 solutions and competing Layer 1s, Ethereum maintains its role as the anchor chain for DeFi innovation. Its combination of security (thanks to proof-of-stake), decentralization, and a vast network of audited smart contracts makes it the safest bet for long-term projects.
Synthetix’s journey—from evaluating EOS to becoming a flagship Ethereum DeFi protocol—reflects a broader industry trend: when it comes to mission-critical financial infrastructure, teams consistently return to Ethereum.
Frequently Asked Questions (FAQ)
Q: Why didn’t Synthetix build on EOS despite its high transaction speed?
A: While EOS offered fast transactions, it lacked mature development tools and a strong security model. Building Synthetix on EOS would have required creating foundational infrastructure from scratch, increasing risk and development time.
Q: Is Ethereum still relevant with so many competing blockchains?
A: Absolutely. Despite competition, Ethereum leads in developer activity, security audits, total value locked (TVL), and institutional adoption. Its ecosystem maturity makes it the preferred choice for serious DeFi projects.
Q: What role do developer tools play in choosing a blockchain?
A: Robust tools reduce bugs, speed up testing, and improve security. Ethereum's ecosystem includes Hardhat, Foundry, Remix, and extensive documentation—critical for building reliable financial applications.
Q: Can other blockchains catch up to Ethereum in DeFi?
A: Some may capture niche markets, but replicating Ethereum’s network effects—developer base, user trust, composability—is extremely difficult. Most cross-chain projects still originate on Ethereum first.
Q: How does capital flow reflect platform strength?
A: Investors favor platforms with proven track records. Over 70% of DeFi TVL resides on Ethereum, signaling strong market confidence in its long-term viability.
Q: What does “composability” mean in DeFi?
A: Composability refers to how easily different protocols can interact—like Lego blocks. On Ethereum, apps like Uniswap, Aave, and Synthetix can seamlessly integrate, enabling innovative financial products.
Ethereum’s dominance isn’t based on hype—it’s built on years of iterative progress, community trust, and unmatched developer support. For founders like Kain Warwick, the decision to build on Ethereum wasn’t just technical—it was strategic.
As DeFi continues to evolve, one truth remains clear: when building the future of finance, most innovators still start with Ethereum.
