Named Frameworks

Reusable mental models extracted from the writing and the building. Each framework is a decision tool — precise enough to apply, tested against real architecture choices. The library grows with every series.

The Rails-First Framework
Build the payment rails before you build the product. Infrastructure decisions made on day one determine what is possible on day one thousand.
The Model
LAYER 3 — Product & Experience (apps, UX, features, brand) ↑ built on top of LAYER 2 — Business Logic (credit, BNPL, KYC, fraud, limits) ↑ built on top of LAYER 1 — Infrastructure (THE RAILS) (ledger, wallets, routing, settlement, provider abstraction, multi-currency)

Most teams start at Layer 3. The Rails-First Framework says: start at Layer 1, design Layer 2 before you touch Layer 3.

When to Apply It

Apply when:

— You will eventually need to control payment flows, merchant relationships, or credit products

— The dominant payment provider in your market is an aggregator, not a direct rail

— You are designing for multi-market or multi-currency from the start

— You want to white-label the infrastructure to others

Do NOT apply when you are validating a product idea in weeks — use the aggregator and swap later.
