The reserve
Every coin on Stabledollar pays 30 basis points of each trade into a single vault. The keeper sweeps it into tokenized Treasuries. This page is what that reserve is doing right now.

How the rate is calculated
USDY accrues by NAV appreciation rather than rebasing, so its yield has to be read out of its price. Endpoint-to-endpoint drift is not good enough: daily venue noise on Solana runs about ±0.3%, while 30 days of accrual at 4%/yr is only ~0.35%, so the signal sits inside the noise, and a 30-day fit lands at r² ≈ 0.01. Stabledollar instead fits an ordinary least squares line to log NAV across a trailing year of sessions, where ~4% of cumulative accrual dominates that noise band, and annualizes the slope. The r² above is how much of the NAV variance the fit explains; if it drops below 0.35 the estimate is treated as unreliable and the panel falls back to the published reference rate rather than printing a number it cannot stand behind.
