Question 1

What is the Pharos Yield Score (PYS)?

Accepted Answer

The Pharos Yield Score (PYS) is a risk-adjusted yield metric scored 0–100 that balances yield magnitude against safety and consistency. It divides the 30-day average APY by a risk penalty derived from the stablecoin's safety grade, then applies a sustainability multiplier based on APY volatility over the same period. Higher-safety stablecoins incur a lower risk penalty, so their PYS reflects their yield more faithfully.

Question 2

How are stablecoin yields sourced?

Accepted Answer

Yields are resolved through deterministic on-chain reads, curated DeFiLlama sources, price-derived or rate-derived fallbacks, and curated lending opportunities. Rankings are refreshed every 30 minutes and now preserve source-specific history so trailing APY metrics stay tied to the active source.

Question 3

What does 'risk-adjusted' mean for stablecoin yield?

Accepted Answer

Risk-adjusted yield accounts for the safety of the stablecoin issuing the yield, not just the raw APY. A stablecoin with a high safety grade (A or A+) receives a low risk penalty in the PYS formula, so even a moderate APY can score well. Conversely, a risky stablecoin must offer significantly higher raw yield to achieve the same PYS, reflecting the extra risk borne by the holder.
