Why is the USDS Safety Score 100/100?

The score is calculated based on asset stability, protocol audit history, and chain security, then adjusted for liquidity depth ($362,682,663) and utilisation rates.

Safety Audit: USDS on Spark

Safety Score Calculation Methodology

Base Score (Typically 60-80 pts)

Weighted Average Formula:
Base = (Asset Score × 0.4) + (Protocol Score × 0.4) + (Chain Score × 0.2)

Risk Penalties

Low TVL (<$1M): -5 to -15 pts
Very High Util (>90%): -10 pts (withdrawal risk)
Extreme APY (>15%): -5 to -10 pts (volatility risk)
Smart Contract Risk: -20 pts if audits are outdated

Market Risk Assessment

Beyond the code, we assess the financial health of the pool. Boasting $362,682,663 in secured assets, the pool demonstrates strong health. A TVL of this magnitude suggests that the smart contracts have withstood the test of time and attracted significant yield farmers interest. This depth is critical for institutional participants who require minimal slippage on exit.

Yield Sustainability

The current APY of 3.04% must be weighed against the utilisation rate of 73.64%. Operating at 73.64% efficiency, the lending market for USDS is functioning as intended. There is ample buffer for withdrawals while still generating consistent interest for suppliers. A sustainable yield is derived from genuine borrower demand, not just inflationary token emissions.

Protocol Security

Spark on Ethereum has been evaluated for historic exploits. The score of 100 integrates the protocol's age and its resilience during previous high-volatility events.

Understanding DeFi Risks

What is Smart Contract Risk? Smart contract risk refers to the possibility of bugs or vulnerabilities in the code governing the protocol. Even audited protocols can suffer exploits if unforeseen vectors are discovered.

What is Financial Risk? Financial risk involves market factors like liquidity crises (inability to withdraw) or asset de-pegging. Our score penalizes low liquidity pools to account for this.

Is the Safety Score a guarantee? No. The score is a probabilistic assessment based on historical data and current metrics. It cannot predict "black swan" events or zero-day exploits.
