# Multi-layered defence

RealFi's "multi-layered defense framework" is a comprehensive risk management architecture designed to withstand extreme market stress by embedding structural, financial, and behavioral protections at every level of the system.

Rather than relying on a single fail-safe, the protocol ensures resilience across four distinct levels:

1. **The asset level:**

   RealFi applies rigorous underwriting standards supported by real-time credit analytics. The performance of borrowers is continuously monitored, tracking metrics like collections, cash-flow health, and default rates.

   If risk thresholds are breached, contractual protections – such as early repayment triggers or collateral enforcement – can be activated immediately to mitigate risk before losses have a chance to compound.
2. **The deal (transaction) level:**

   Each individual transaction is structured with embedded credit safeguards to limit downside risk.

   These protections include conservative loan-to-value caps and minimum debt service coverage requirements applied at origination, with self-amortising structures preferred and enhanced Investment Committee scrutiny of any bullet or refinancing-dependent structure. This ensures that every deal has sufficient collateral buffers and strong cash-flow coverage right from the point of origination.
3. **The portfolio level:**

   To prevent overexposure to any single risk factor, the broader portfolio is managed using strict duration and concentration controls.

   *Duration discipline:* The portfolio's weighted average life is capped at 1.25 years, with sleeve-level maturity limits keeping the book short. This allows RealFi to rapidly rotate capital or exit jurisdictions if macroeconomic or regulatory conditions deteriorate.

   *Geographic diversification:* Jurisdictional exposure is heavily restricted, with emerging market exposure capped at 50% of the portfolio, no single Tier 2 jurisdiction exceeding 25%, and Tier 3 (frontier) markets capped at 10% in aggregate, ensuring the foundation remains anchored in high-quality operating environments.
4. **The protocol level:**

   At the highest level, RealFi utilizes on-chain circuit breakers mechanisms and stability fund to preserve solvency, liquidity, and price stability.
