Observed quotes from Philidor events linked to this asset, one line per chain, with depegs marked on the same timeline.
No Philidor peg observations for USDS in this window.
Daily investable TVL plus TVL-weighted APR for the exact symbol. Multi-vault assets are aggregated server-side; empty days stay honest rather than being backfilled in the browser.
Derived points reconstruct historical vault snapshots using today's vault eligibility; observed points are captured directly from that day's investable set.
The score starts as the category-weighted sum of these 0-10 dimensions. Review status, stale evidence, hard-fail flags, chain and dependency penalties, or an underlying-asset cap can lower it. Full methodology
Philidor continuously observes the published backing evidence for USDS and keeps its provenance explicit. That check runs position by position on-chain, at pinned finalized blocks. The shadow backing score below is what that composition measures under our framework. It is published for transparency and does not yet feed the published risk rating shown on this page.
Deployments currently covered by Philidor's asset registry; this is not a claim that no other deployments exist.

84.5% of backing value directly reproduced on-chain at pinned finalized blocks; the remainder relies on the cited source or is not reproducible from public chain state. Composition source: ba_labs, observed 2026-10-14 06:39 UTC. Philidor’s backing look-through. Evidence method is explicit per row: pinned-block on-chain checks, issuer-published third-party attestation results, or issuer report. Philidor does not independently fetch the auditor artifacts behind issuer-published attestation results. Issuer-reported values are never relabelled as independently verified. The raw onchain_verified_pct here may remain non-zero on an inadmissible snapshot for diagnosis; /v1/por publishes the fail-closed decision-current value. Since methodology v6, for coins whose composition is genuinely observed (mostly non-fail-closed sleeves), the backing ceiling caps the SERVED risk score — effective_score/effective_tier reflect it and ceiling_enforced marks the rows where it applies. Mostly-unobserved snapshots (issuer-report stubs) stay observational and never cap.
