Tranche RealFi

Tranche Protocol — Overview

Tranche Protocol is an institutional-grade Real-World Asset (RWA) yield optimization protocol built on Mantle. It brings structured credit tranching on-chain, transforming a single tokenized RWA yield stream into multiple, risk-segmented financial products.

The protocol splits yield into two distinct tranches:

• Senior Tranche (msUSD-S): Stable, low-risk returns with first-loss protection

• Junior Tranche (msUSD-J): Leveraged exposure with higher volatility and return potential

This design gives investors explicit control over risk–reward profiles while retaining full DeFi composability.

Asset Layer — Deterministic RWA Yield

At the Asset Layer, users deposit msUSD into an on-chain RWA Vault. The vault’s Net Asset Value (NAV) deterministically accrues over time based on underlying real-world asset yield.

• Vault shares represent the underlying RWA position

• Shares act as the base asset for tranching

• Yield accrual is transparent and fully on-chain

These vault shares flow directly into the tranching system.

Tranching Layer — On-Chain Yield Structuring

The Tranche Core contract orchestrates all critical system logic:

• Minting and redemption of tranche tokens

• Swap operations between Senior and Junior tranches

• Market safety checks and invariant enforcement

The Tranche LEX, a fork of Covenant’s Latent Swap model, computes:

• Fair mint and redemption ratios

• Tranche pricing and fees

• Yield distribution using oracle inputs

This ensures transparent, deterministic, and verifiable yield allocation between tranches.

Compliance & Institutional Controls

Tranche Protocol is designed to support regulated asset workflows while remaining fully on-chain.

• A KYC Registry gates sensitive actions, especially Senior tranche issuance and transfers

• A Curator / Oracle Router controls approved pricing sources

• Supports vault NAV adapters and optional Pyth price feeds

These controls allow institutional participation without compromising transparency or auditability.

Token Layer — Composability & Capital Efficiency

Both msUSD-S and msUSD-J are standard ERC-20 tokens, enabling full integration across DeFi.

Beyond yield generation, tranche tokens unlock capital efficiency:

• Senior tranche tokens can be used as collateral

• Users can borrow HackUSD, the protocol’s stablecoin

• Borrowing is governed by oracle-valued pricing, haircuts, and LTV parameters

The Stable Borrow Vault enforces clear liquidation logic and safety margins, enabling leverage strategies while maintaining system solvency.
