TSSO is a new oracle model designed to securely bring Net Asset Value (NAV) data on-chain for tokenized funds and assets.

1. The Problem?
Traditional NAVs for private funds are calculated off-chain by a single fund administrator. This creates a trust issue in DeFi: verifying the authenticity of NAV data on-chain is challenging since there’s no market aggregation, relying on a single point of trust.

2. The Solution: TSSO
Marcin, co-founder of RedStone, introduced the TSSO concept at an exclusive event for developers in the RWA and oracle space in 2024.

However, the solution was brought to light in July 2025, in partnership with Securitize, announcing the collaboration to bridge TradFi and DeFi, being piloted with clients like BlackRock’s BUIDL fund and KKR’s Health Care Strategic Growth Fund II.

TSSO operates like Git for financial data. Each NAV update is a signed commit in a cryptographically linked chain, creating an auditable, tamper-proof history. This ensures trust without relying on the source’s goodwill, providing transparency and traceability.

TSSO enables institutional assets, such as private credit or real estate funds, to integrate with DeFi protocols by turning off-chain NAVs into verifiable on-chain data. This unlocks liquidity and programmability while maintaining TradFi’s control and compliance standards.

3. TSSO vs. Standard Oracles
Standard oracles aggregate data from multiple sources to prevent manipulation. Private fund NAVs, however, come from a single source, making aggregation infeasible.

TSSO ensures trust by cryptographically linking each NAV update to a trusted source, preventing tampering. Innovation!

4. Dual-Key Architecture
TSSO employs a Secure Root Key for major updates, such as fund structure changes, and a Derivative Chain Key for frequent NAV adjustments. This structure balances security and efficiency, ensuring every update is verifiable and linked to prior updates.

5. Key Use Cases
TSSO supports multiple applications:

✅Lending Vaults: NAVs as collateral for DeFi loans.

✅Structured Credit: Building on-chain private debt products.

✅Tokenized Funds: Real-time portfolio tracking.

✅Auditable Reporting: Transparent data for regulators and investors.

6. Importance for the future
TSSO provides TradFi with the control, traceability, and compliance needed to engage with DeFi confidently. By making NAVs usable on-chain, it enables a new era of programmable finance, bridging traditional and decentralized systems.

TSSO is used by major players like BlackRock and KKR. As adoption grows, expect increased tokenized funds, DeFi liquidity, and institutional-grade infrastructure reshaping finance.

TSSO is a critical step toward mainstream tokenized asset adoption. Trillions!
