# Conduct a Solvency Assurance Audit

## Overview

A **Solvency Assurance Audit** evaluates whether a protocol's balance sheet and liquidation mechanisms can withstand shocks—ensuring the system remains solvent and able to honor obligations even under stress.

## Why Solvency Assurance Is Critical

Code and parameter safety alone don't guarantee viability. Protocols must also demonstrate that:

* **Assets ≥ Liabilities** under adverse conditions
* Liquidation mechanisms can act effectively and fast enough to preserve solvency

## Pre-Audit Preparation

* **Clearly define scope**: Identify pools, collateral types, leverage thresholds, and liquidity concentrations. Make assumptions explicit.
* **Run internal dry-runs**: Perform initial solvency checks before engaging external auditors.
* **Test coverage**: Prioritize fork-level and stress simulations, including edge-case modeling and fuzzed inputs.

## Audit Process and Components

### 1. Balance Sheet Analysis

* Evaluate total assets (collateral, reserves) vs. liabilities (outstanding debt, redemption obligations).
* Identify **exposure concentrations** (e.g., collateral concentration in a volatile asset).

### 2. Stress Testing Scenarios

* Simulate severe events:
  * Rapid price crashes (e.g., 50% drop in ETH in 24 hrs).
  * Liquidity shortages.
  * Correlated multi-asset failures.

### 3. Liquidation & Liquidity Dynamics

* Stress test liquidation execution paths, focusing on:
  * Market depth limitations.
  * Time-to-liquidate vs. price decay.
  * Slippage and cascading risk effects.

### 4. Risk Metrics

* **Solvency ratios** under stress.
* **Liquidation capacity**: how much collateral can be offloaded before breaching solvency.
* Early-warning indicators for escalating risk.

### 5. Deliverables

* **Solvency health report** with scenario analyses.
* **Recommendations** for:
  * Improved collateral diversification.
  * Adjusted liquidation thresholds or incentives.
  * Buffer reserves or liquidity backstops.

## Post-Audit Actions

1. **Test regression scenarios** — Ensure recommended changes fix the issues and prevent recurrence.
2. **Allocate buffer time** — Allow for testing, governance discussion, and revalidation.
3. **Update documentation** — Reflect all modifications, including new risk thresholds or monitoring protocols.
4. **Execute testnet trials** — Simulate the audit recommendations under realistic conditions.
