# Vertically Integrated Financial Primitives for the Real World

Vend bridges the gap between real-world business performance and on-chain capital efficiency.\
\
*DeFi built composability across on-chain money.*\
*Vend builds **composability across real-world machines.***

Each unmanned business — laundromat, vending machine, kiosk, or locker — runs on the same three financial primitives that power every economy: **payments, loyalty, and credit.**

\
Until now, these functions lived in isolation — a closed payment app here, a loyalty card there, a bank loan somewhere else. Vend vertically integrates these layers on-chain, creating a single, programmable liquidity system that feeds itself.

The Vend protocol is supported by the three key components:

[**VendPay — Everyday Payments, On-Chain**](/vend-docs/vertically-integrated-financial-primitives-for-the-real-world/vendpay.md)

[**VendEarn - Real Yield From Real Machines**](/vend-docs/vertically-integrated-financial-primitives-for-the-real-world/vendearn.md)

[**VendLoyalty — Rewards That Compound**](/vend-docs/vertically-integrated-financial-primitives-for-the-real-world/vendloyalty.md)

### The Triple Flywheel Effect

Each financial transaction strengthens the protocol — creating a **triple flywheel of payments, yield, and loyalty.**
