The Future of Institutional Settlement Is Already Decided: How SBI and Robinhood Prove the L1–L2 Modular Architecture
3-Point Summary
- SBI’s L1-based stablecoin and Robinhood’s L2-based architecture together prove why Ethereum’s modular L1–L2 model is the future of institutional and consumer settlement.
- SBI’s choice of L1 reflects the core requirements of institutional settlement—legal certainty, finality, and regulatory robustness—while Robinhood demonstrates the scalability and UX advantages of L2 execution.
- As institutional activity scales onchain, pure L1 architectures become unsustainable, making L2 execution + L1 settlement the inevitable long‑term structure for both institutions and consumer finance.
SBI proves the stability of Ethereum L1, while Robinhood demonstrates why L2 execution with L1 settlement is becoming the future standard for institutional and consumer finance.

Institutional Settlement’s Future Is Already Decided:
How SBI and Robinhood Prove the L1–L2 Modular Model
In 2026, the Ethereum ecosystem witnessed two symbolic milestones at the same time.
One was SBI issuing Japan’s first trust-based yen stablecoin (JPYSC) directly on Ethereum L1,
and the other was Robinhood building its consumer finance infrastructure on an Ethereum L2-based modular architecture.
These two cases come from different industries, but together they prove why Ethereum’s modular architecture wins from opposite directions. This article explains the future structure along four main axes:
- SBI choosing L1 vs. Robinhood choosing L2
- Why SBI’s choice reflects the essence of institutional settlement, not a “speed trade-off”
- Why L1-only usage becomes impossible in the long run
- The solution: L2 execution + L1 settlement — and why Robinhood shows this future first
1) SBI chose L1, Robinhood chose L2
SBI — Institutional settlement chooses L1
SBI opted for a pure Ethereum L1 structure. JPYSC is Japan’s first trust-based yen stablecoin, where regulation, legal certainty, and final settlement are core requirements. For institutions, safety, irreversibility, and legal finality matter more than raw speed.
Robinhood — Consumer finance chooses L2
Robinhood, on the other hand, combined Web2-level UX with Web3 scalability by adopting an Application Layer + L2 Execution + L1 Settlement architecture. Consumer finance demands high transaction volume, fast response, and low cost — making L2 the natural choice.
2) SBI’s choice reflects the essence of institutional settlement, not a speed compromise
In institutional settlement, the most critical elements are legal certainty, regulatory compliance, asset protection, system resilience, and irreversible final settlement. This domain is driven by high-value, low-frequency transactions, so TPS competition is largely irrelevant.
SBI’s decision to use L1 is therefore not “we don’t care about speed,” but rather a strategic choice to meet the fundamental requirements of institutional settlement. Trust-based stablecoins especially depend on the legal certainty of the settlement layer, and because L2 is an execution layer, it cannot yet match L1’s legal robustness under current regulatory frameworks.

.
3) Why L1-only usage becomes impossible in the long run
SBI’s choice is rational in the early phase, but as more institutions move onchain at scale, a pure L1 structure runs into limits in terms of congestion, gas costs, and scalability.
Ethereum L1 is fundamentally designed to provide final settlement, security, and ETH-based liquidity. When L1 is used as an execution layer, structural inefficiencies emerge. Execution on L2 and settlement on L1 is what aligns with Ethereum’s modular philosophy.
As institutional settlement moves onchain in large volumes, L1-only architectures inevitably hit TPS, block space,
and gas price bottlenecks — a trend already visible across the Ethereum ecosystem. A detailed analysis is available here:

.
In short, institutional settlement can start on L1 alone, but at large-scale adoption, L1 by itself cannot scale. In the long run, an L1–L2 modular structure becomes inevitable, and SBI will also have to move in this direction.
4) The solution: L2 execution + L1 settlement — Robinhood shows the future first
Ethereum’s roadmap points to a clear answer: L2 execution + L1 settlement. L2 handles speed and cost, while L1 provides legal certainty and final settlement — a role separation that satisfies institutional, consumer, and ecosystem needs at the same time.
L2 processes large transaction volumes quickly and cheaply, delivering the scalability required by consumer finance and large-scale applications. This is exactly the execution-layer-centric model Robinhood chose.
L1, in contrast, serves as the settlement layer with strong security and irreversible finality. In regulated environments where legal certainty is non-negotiable, institutional settlement still needs L1.
A deeper exploration of why this modular structure is becoming the future standard can be found here:

.
By executing on L2 and settling on L1, Robinhood’s chain achieves speed, scalability, and legal robustness simultaneously. This is the model both consumer finance and institutional settlement are converging toward, and SBI’s continued reliance on L1 reflects the necessity of this structure from the institutional side.
Conclusion: SBI proves L1’s stability, Robinhood proves L2’s future
SBI’s choice is perfectly reasonable for the “early phase of institutional settlement.” But in a “large-scale institutional onchain era,” its scalability limits become clear.
Robinhood, meanwhile, has already implemented what is likely to become the future standard:
- Execution on L2
- Final settlement on L1
- Web2-level UX at the application layer
SBI demonstrates the stability and trustworthiness of Ethereum L1,
while Robinhood demonstrates that an L2+L1 modular architecture will become the future standard for both consumers and institutions.
Institutional settlement will ultimately converge on L2 execution + L1 settlement, and Robinhood’s chain is the first real-world example to show that future ahead of time.
