Solana Won on Speed. But Ethereum Is Winning Finance
3-Point Summary
- Onchain finance is shifting from a race of speed and scalability to a competition of monetary policy and tokenomics.
- Solana’s inflation-based model accelerates growth but creates long-term constraints for RWA, institutional payments, and settlement infrastructure.
- Ethereum’s deflationary or neutral supply model provides value stability and predictability, making it the preferred foundation for institutional onchain finance.
Onchain finance is no longer defined by speed alone—its future depends on which chain can build the most trusted tokenomics.

Solana Inflation vs Ethereum Deflation: Tokenomics That Decide the Future of Onchain Finance
As onchain finance rapidly expands into the regulated world, chain speed and scalability alone can no longer explain institutional choice. What matters is tokenomics (monetary policy) — how a chain manages supply and preserves long‑term value — which is becoming the core standard for RWA, institutional settlement, and global clearing infrastructure.
Solana has used an inflationary model to drive fast growth and high staking rewards, but as it moves into the phase of RWA, institutional payments, and onchain finance, this structure can become a long‑term constraint. Ethereum and Solana both use Proof of Stake (PoS), yet the source and structure of their security are fundamentally different.
Ethereum secures its network through capital‑based security, while Solana’s security relies on the execution performance of high‑throughput validators. In other words, even though both are PoS chains, they differ in the fundamental answer to “what actually keeps the network safe?” For a deeper dive, see the previous article “The Truth About PoS Security: Ethereum Is Secured by Capital, Solana by Performance” .
Since The Merge, Ethereum’s economic structure has been driven by two main pillars. Issuance is centered on staking rewards, while burn is driven by network activity. Combined, these two forces allow Ethereum to operate under a deflationary or neutral supply model. Ethereum’s evolving economic identity is discussed in detail in “Ethereum’s Identity Crisis: Digital Money or Network Security Asset” .
This supply structure plays a critical role in the expansion of onchain finance. Robinhood Chain combines ultra‑fast throughput, ultra‑low gas fees, and Ethereum‑based security and compatibility to create one of the most natural entry paths for traditional finance users into Web3. Robinhood Chain’s success is possible precisely because Ethereum has operated under a deflationary or neutral supply model since EIP‑1559, functioning as a stable settlement layer (L1). For more context, see “Settlement on L1, Execution on L2: How Robinhood Chain Set a New Standard for Onchain Finance” .
In the end, Ethereum’s deflationary model delivers supply stability and value preservation, allowing it to become a trusted onchain financial infrastructure for global institutions.
Solana’s recent consideration of a deflationary model has a clear motivation. To move into the next stage of onchain finance — RWA, institutional payments, and global settlement infrastructure — a predictable supply model is essential. Speed and scalability remain Solana’s strengths, but the ultimate battleground for onchain finance will be decided by tokenomics.
1) Solana: Inflation‑Based New Issuance Model
Solana adopts a model of continuous new issuance (inflation) to secure the network and fund staking rewards. The initial annual inflation rate was 8%, decreasing by 15% each year until it stabilizes around roughly 1.5%.
- Most newly issued SOL is paid out as staking rewards.
- Not staking leads to dilution of one’s holdings.
- Continuous supply growth creates pressure on long‑term value stability.
- 50% of transaction fees are burned, but this is not enough to fully offset inflation.
In short, Solana is fundamentally an inflationary token, and staking is the only way to defend against dilution. This offers attractive short‑term rewards, but it introduces limitations when measured against the long‑term value stability demanded by institutional‑scale capital.
2) Ethereum: Deflation‑Based Burn Model
Since EIP‑1559, Ethereum has shifted to a deflationary or neutral supply model. The base fee of each transaction is automatically burned, creating a structure where ETH supply can decrease as network activity increases.
- Higher network usage leads to a reduction in ETH supply.
- Staking rewards are modest, but supply stability is high.
- The value structure favors long‑term holders.
- It provides the predictable supply model that institutions prefer.
Ethereum has thus become a deflationary asset whose value is directly linked to network activity. This structure allows global institutions to view ETH as both the foundational asset of onchain finance and a reliable settlement layer.
3) Why RWA Is Not “Any Chain Will Do” but “Which Chain You Use Matters Deeply”
RWA is backed by safe underlying assets such as government bonds or money market funds, but the actual operation runs on top of a chain’s tokenomics and settlement structure. As a result, supply stability, fee predictability, and regulatory compatibility of the chain directly influence institutional adoption.
Consider an institution issuing $1 billion worth of RWA on Solana. Throughout the lifecycle of that RWA, the institution must continuously use SOL for settlement, clearing, and transaction fees. As long as Solana maintains an inflationary model, SOL supply will keep increasing.
- Long‑term value dilution: the real value of held SOL declines over time.
- Uncertain settlement costs: inflation‑driven price changes make cost modeling difficult.
- Regulatory friction: regulators are reluctant to endorse tokens with structurally expanding supply as “stable.”
- Complex accounting and financial modeling: inflation and staking decisions affect value, increasing operational burden.
No matter how safe the underlying asset is, if the economic model of the chain that hosts it is unstable, the trust and scalability of the RWA itself are constrained. This is why global institutions favor Ethereum’s deflationary or neutral supply model, and why Solana’s discussion of a deflationary transition is not a cosmetic tweak but a structural response to institutional requirements.
Conclusion
Onchain finance has moved beyond a pure technology race. We are now in a phase where each chain’s monetary policy and tokenomics decide the outcome. Solana has undeniable strengths in speed, scalability, and user experience, but its inflationary model can become a long‑term constraint as it expands into RWA, institutional payments, and settlement infrastructure.
Ethereum, by contrast, uses a deflationary supply model to deliver the value stability, predictability, and regulatory friendliness that institutions demand, cementing its role as the standard layer for onchain finance. This is not just a difference in token design; it is a question of which chain can credibly sit at the center of global financial infrastructure.
Solana’s exploration of a deflationary model is therefore not merely a tokenomics adjustment, but a strategic move to meet the minimum conditions for institutional finance. Ultimately, the future of onchain finance will be decided by how much trust in tokenomics can be built on top of high speed and broad scalability.
