The next is a visitor publish and opinion from Michael Egorov, Founding father of Curve Finance.
As DeFi edges nearer to mainstream finance, it should stability neutrality, safety, and throughput. In 2025, that stability is more and more outlined by two competing architectural visions.
The evolution of DeFi has all the time hinged on one core query: what sort of infrastructure can we need to construct the way forward for finance on? Because the area matures and edges towards integration with world monetary programs, the urgency of this query solely intensifies.
In 2025, this choice is not purely technical. It’s a contest between two visions: Ethereum’s modular, decentralization-first stack and Solana’s high-performance, monolithic strategy. The end result will assist decide what the following section of blockchain-based finance appears like—and form the structure of tomorrow’s world monetary programs.
On this article, I share my perspective on how each networks are positioning themselves for the longer term, and which is extra prone to emerge forward in the long term.
Ethereum: The Basis of Severe DeFi
Ethereum is greater than only a blockchain—it’s the bedrock of recent DeFi. It’s the place safe, composable functions can thrive and the place long-term monetary infrastructure is being constructed. Institutional gamers flip to Ethereum once they need to tokenize property with confidence, and capital flows right here for safety. The truth that over 55% of whole worth locked (TVL) throughout main chains resides on Ethereum attests to its dominance.
Not like Solana’s one-size-fits-all Layer 1, Ethereum has embraced a modular scaling strategy. Layer 1 stays the core basis, whereas Layer 2s deal with particular workloads similar to micro-transactions or gaming, avoiding congestion on the principle chain. This construction preserves decentralization whereas enabling scale. With the rollout of Proto-Danksharding in early 2025, Layer 2 transaction prices have dropped considerably—cementing Ethereum’s lead in modular structure.
That stated, Ethereum’s mannequin has trade-offs. Its reliance on Layer 2s can introduce fragmentation. Some DeFi primitives must reside on Layer 1 for full composability. Whereas remoted functions like order ebook DEXs can perform on L2s, these options typically really feel like a brief repair, not a long-term design. Really built-in DeFi calls for synchronous, on-chain composability—which works finest when every little thing operates on the identical base layer.
However Ethereum’s best energy is its uncompromising dedication to decentralization. It is among the most politically impartial blockchains in existence—a key trait in an more and more regulated atmosphere. Velocity and consumer expertise could be optimized over time, however decentralization is a founding precept. As soon as compromised, it’s practically unattainable to revive.
Developer expertise is one other edge. Writing good contracts on Ethereum is considerably less complicated than on Solana, enabling builders to provide safe, well-tested code. This maturity is a part of the rationale why Ethereum builders are snug making contracts immutable—there’s confidence within the safety. It’s no coincidence that almost each main DeFi innovation originated on Ethereum. With over 1,388 deployed protocols in comparison with Solana’s 232, the numbers communicate for themselves.
When safety, composability, and developer confidence align, your entire ecosystem advantages.
Solana: Quick and Environment friendly, However Centralized
Solana addresses the identical scaling problem from a special angle. Its monolithic structure retains every little thing on a single Layer 1. This gives tangible advantages: extraordinarily quick transactions, low charges, and a seamless consumer expertise.
From a uncooked efficiency standpoint, Solana is compelling—able to processing 3,000–4,000 transactions per second (TPS) right now, with expectations of reaching over 1 million TPS by means of the upcoming Firedancer validator. These numbers, based mostly on testnet outcomes, are spectacular in comparison with Ethereum’s common of 15–30 TPS.
Nonetheless, this efficiency comes with trade-offs. Solana’s design features a chief node that sequences transactions. Whereas this improves throughput, it introduces centralization dangers. The community is distributed, however not really decentralized. That distinction issues—particularly in a world the place establishments prioritize political neutrality and censorship resistance.
Nonetheless, not each use case requires deep decentralization. For instance, inner CBDCs or consumer-facing functions in gaming and fintech might profit from Solana’s throughput and UX. I wouldn’t be stunned if we see state-adapted variations of Solana deployed in managed environments.
But regardless of Solana’s momentum, Ethereum stays the platform of alternative for what I name “critical cash.”
Structural Soundness vs. Mass Adoption
The core DeFi debate in 2025—and past—facilities on what the sector ought to optimize for: structural integrity or mass adoption? Ought to we construct resilient, decentralized, and composable programs, even when they’re slower and extra complicated? Or prioritize scale and UX on the expense of core crypto values?
Chasing adoption with out structural soundness is short-sighted. If protocols compromise on safety or decentralization, regulators will inevitably impose the identical constraints that burden conventional finance. At that time, the promise of DeFi can be misplaced.
That’s why institutional capital continues to favor Ethereum—and why I imagine that desire will maintain. Neutrality and safety can’t be retrofitted; they have to be constructed into the bottom layer from the beginning.
If we would like DeFi to outlast the hype cycles and type the spine of a brand new world monetary order, Ethereum gives essentially the most strong path ahead. It offers us the very best shot at constructing monetary rails which are resilient, safe, and unco-optable.
