Programmable Money, Payments & Financial Systems on Sui

Problem

Payments and DeFi today are disconnected:

• Payments are static transfers
• DeFi is complex and siloed
• Users must manually orchestrate everything

On Sui, this changes: Payments can become programmable financial actions.

Examples:

• A payment that automatically invests
• A salary that streams and earns yield
• A wallet that intelligently routes funds

Overview

Sui introduces a fundamentally different model for building financial systems:

• Assets are objects, not just balances
• Transactions can bundle complex logic atomically (Programmable Transaction Blocks)
• Smart contracts (Move) enforce ownership and composability at the type level

This enables something beyond traditional DeFi:

Programmable money — where assets, logic, and flows are natively composable.
