Beyond Bitcoin: The Moment Ethereum Becomes the Foundation of the Financial System
3-Point Summary
- Traditional finance is undergoing a structural shift in which on‑chain finance becomes core infrastructure — with Ethereum emerging as the central base layer.
- Ethereum L2s, especially Robinhood Chain, demonstrate that traditional finance is now expanding directly onto Ethereum-based on‑chain liquidity rails.
- The three‑layer structure of Bitcoin, Ethereum, and stablecoins — combined with the U.S. banking system’s ‘Permissioned + Public’ hybrid model — is solidifying Ethereum as the foundation of future financial infrastructure.
As traditional finance moves on‑chain, Ethereum is emerging as the foundational layer of the new global financial system.

Beyond Bitcoin: The Moment Ethereum Becomes the Foundation of the Financial System
After 2027, the transformation of financial infrastructure is no longer just a technology trend. Traditional finance (TF) is undergoing a structural shift in which on‑chain finance becomes the core infrastructure, and at the center of this shift stands one clear axis: Ethereum.
In particular, Arthur Hayes’s view that ETH will outperform BTC is not merely a price prediction. It reflects Ethereum’s structural strength as the emerging core layer of financial infrastructure. The market is beginning to see Ethereum not as a “speculative asset” but as the base layer of the financial system.
This shift did not appear out of nowhere. It has been steadily unfolding over the past few years, as on‑chain finance has moved into the position of core infrastructure for traditional finance. The following reference articles provide important background analysis on how this structural transition has been taking shape:

The four developments below may look like separate events, but they ultimately point in the same direction.
1) The Market Is Beginning to Recognize Ethereum’s Structural Strength
Global markets are no longer treating Ethereum as just another “altcoin.” They are starting to see it as a financial infrastructure layer. From stablecoin settlement and L2 scalability to institutional adoption and regulatory alignment, Ethereum is already performing core functions of the financial system.
Arthur Hayes’s ETH thesis is not about short‑term price action. It reflects structural strength as financial infrastructure. The fact that nearly half of all stablecoins operate on Ethereum means that banks and institutions have little choice but to prioritize ETH when they move into on‑chain finance.
- ETH is increasingly perceived as a financial infrastructure layer, not just an investment asset
- Stablecoins, L2s, and institutional adoption reinforce Ethereum’s structural strength
- Banks’ on‑chain strategies are converging around Ethereum as the default base layer
2) The Explosive Growth of Ethereum L2: Robinhood Chain
Ethereum’s strength is also clearly visible at the L2 level. A prime example is Robinhood Chain. The fact that a traditional finance company has built a chain on Ethereum L2 that can directly compete with Solana is highly symbolic.
Robinhood Chain’s daily trading volume is approaching $2 billion, and its DEX volume has surpassed Solana. This is not just a technical success story; it is a signal that traditional finance is entering the on‑chain liquidity arena in earnest.
- Robinhood Chain is a flagship success case of an Ethereum L2
- Traditional finance is directly entering the on‑chain liquidity market
- The direction mirrors banks’ choice of hybrid architectures built around Ethereum
3) The Three-Layer Structure of Bitcoin, Ethereum, and Stablecoins Is Strengthening
On‑chain financial infrastructure is increasingly crystallizing into a clear three‑layer structure. Bitcoin serves as the value‑storage layer, stablecoins function as the digital‑dollar layer, and the layer that actually connects and moves financial infrastructure between these two is Ethereum.
Ethereum sits at the center of this structure not just because of technical superiority, but because the throne of stablecoin settlement resides on Ethereum. Issuance, circulation, settlement, and security of stablecoins are concentrated on Ethereum, and most flows between institutions, exchanges, custodians, and banks are executed on Ethereum rails.
- BTC = value storage
- ETH = financial infrastructure — the de facto throne of stablecoin settlement
- Stablecoin = digital dollar
4) The Path Chosen by U.S. Banking: The ‘Permissioned + Public’ On‑Chain Settlement Revolution
U.S. banking has already formally adopted a ‘Permissioned + Public’ hybrid architecture. This structure satisfies internal controls, regulatory compliance, and privacy requirements, while simultaneously securing global liquidity and openness.
The permissioned execution layer is built on Hyperledger Besu, restricted to banks and financial institutions with full KYC/AML. The settlement layer, however, runs on Ethereum L1/L2, handling global payments, interactions with external institutions, and flows to exchanges and custodians.
When banks choose on‑chain finance, Ethereum sits at the center of that choice.
- Hyperledger Besu + public Ethereum L1/L2 is the officially chosen architecture for U.S. banking
- It balances internal control with global openness
- Bank‑issued stablecoins ultimately operate on Ethereum‑centric hybrid rails
Conclusion: All Roads Lead to Ethereum
Once traditional finance commits to on‑chain finance, its infrastructure choices increasingly converge on Ethereum.
- The market is recognizing Ethereum’s structural strength
- Ethereum L2s have become the expansion stage for traditional finance on‑chain
- The three‑layer structure has become the default design of financial infrastructure
- Banks have chosen a ‘Permissioned + Public’ hybrid with Ethereum at the core
This is the new baseline for financial infrastructure after 2027.
