RWA 3.0: IOST’s Paradigm Shift Toward a Modular On-Chain Real-World Assets Infrastructure

From “Static Certificates” to “Programmable Financial Building Blocks”

1. Redefining RWA 3.0: A Modular Principal–Yield Separation Framework

As DeFi and TradFi converge, traditional tokenization of real-world assets (RWA) — bonds, real estate, and more — has mostly meant mirroring these assets on-chain as static certificates. This approach lacks the flexibility and composability modern finance demands. IOST’s RWA 3.0 introduces a modular Principal–Yield separation framework that transforms on-chain assets into an institutional-grade, DeFi-ready paradigm.

In current tokenization models, principal and yield are packaged together, constraining on-chain utility and liquidity, neither can be used independently for collateral or for advanced strategies.

IOST’s RWA 3.0 splits each asset into two independent token modules:

• P-Token (Principal Token): Represents the return of principal at maturity, designed for low-risk, stable-yield institutional investors.
• Y-Token (Yield Token): Represents the ongoing yield stream, freely tradable, collateralizable, and composable for DeFi-native users.

This separation enables true on-chain programmability and composability of cash flows, elevating RWA from “static certificates” to “dynamic financial instruments” by:

• Creating secondary markets with real-time yield pricing to attract institutions and market makers
• Enhancing capital efficiency and leverage opportunities, unlocking deeper liquidity
• Providing developers a sandbox to build structured products and hedging strategies
• Bridging DeFi and TradFi value on-chain and off-chain

Static Certificates ➔ Programmable Assets

• Transfer & Trade: Holders can freely circulate tokens on secondary markets
• Collateral & Lending: Tokens can be staked or borrowed against across lending protocols
• Compose & Derive: Tokens power leveraged, principal-protected, and other innovative DeFi products
• Customize & Integrate: Developers can rapidly build tailored financial tools atop the P/Y framework

2. Why IOST Is Uniquely Positioned to Pioneer RWA 3.0

Delivering on this vision requires excellence in Compliance, Technology, and execution — three areas where IOST leads:

Technical Foundation: High-Performance, Modular Multichain Architecture

• IOST’s proprietary subnet framework lets RWA 3.0 deploy as Layer 2 on multiple public chains or custom subnets, while maintaining native EVM compatibility.
• Integrated cross-chain bridges, liquidity engines, oracles, DID, and payment modules provide end-to-end RWA lifecycle management.
• Each subnet is fully customizable — tuning performance and compliance modules per L1 characteristics, achieving true plug-and-play multichain deployment.

Compliance Advantage: Full-Spectrum Regulatory Support in Japan

• IOST is JVCEA-greenlisted and is listed on JFSA-regulated exchanges (e.g., Coincheck, BITPoint).
• Direct collaboration with financial institutions and regulators ensures every issuance and trade meets legal requirements.
• This compliance foundation enables IOST to engage meaningfully with financial institutions and regulators in one of the world’s most structured markets.

Proven Real-World Execution: Institutional & Retail On-Ramps

• Partnership with licensed platform DigiFT: over US$5.7 billion in institutional bond issuances on-chain.
• PayPIN Ring™ with biometric authentication enables compliant retail investors in RWA.

Together, IOST’s modular tech stack, regulatory credentials, and live deployments address RWA’s core challenges — regulatory barriers, low liquidity, and user mismatch — driving the transition from conceptual finance to sustainable on-chain markets.

3. Why Japan Is the Ideal Launchpad for RWA 3.0

Japan offers the world’s most mature regulatory environment for RWA innovation. IOST chose Japan for its RWA 3.0 debut based on three pillars:

1. Clear Regulatory Pathways

• Japan’s FSA classifies crypto assets under the Financial Instruments and Exchange Act, distinguishing financing vs. non-financing tokens.
• The updated Payment Services Act provides legal clarity for stablecoins and crypto custody.

2. Robust Market Demand

• As the world’s largest holder of US Treasuries (over US$1 trillion), Japanese investors seek digital access to dollar-denominated assets.
• On-chain US Treasuries meet both currency allocation and digitization needs, driving strong institutional and retail uptake.

3. Industry Consensus

• The Japan Crypto-Asset Business Association (JCBA) has published RWA issuance and trading guidelines, supporting standardization and regulatory dialogue.
• These frameworks accelerate coordination between projects, regulators, and industry stakeholders, speeding time-to-market.
