# Exposure Report Methodology

> How the Stablecoin Quantum Exposure Report is computed, what it covers, and what it deliberately does not claim

The **Stablecoin Quantum Exposure Report** is a recurring, citable snapshot of
signature-exposure and dormancy across the Ethereum stablecoin holder cohorts
WalletWall already tracks. Figures are **observations over observed cohorts —
observations, not predictions** — and every edition embeds its own provenance
and boundaries.

## Scope

* **Ethereum cohort sample only.** The report aggregates the holder cohorts
  WalletWall's scheduled analytics already cover (active, whale, dormant
  cohorts). It is a cohort sample, not full-market coverage, and says so in
  the artifact itself.
* **Zero new data collection.** Editions are computed from the existing
  **Dune auto-run** snapshot the app already caches. Publishing an edition
  never executes a query and never adds analytics cost.

## How figures are computed

All aggregation is a pure, deterministic function
(`src/lib/exposure-report/buildExposureReportEdition.js`) over the cached
cohort snapshot:

* **Wallets observed** — count of cohort leaves in the snapshot.
* **Exposed-signature share** — wallets flagged with observed signature
  exposure, as a share of wallets observed, plus their share of observed
  cohort value.
* **Dormant share** — wallets in the dormant cohort or carrying dormancy
  flags.
* **Top-10 value concentration** — the ten largest observed balances as a
  share of total observed cohort value.
* **Observation floor** — below 10 observed wallets an edition reports
  *insufficient data* with no figures. Small samples are not findings.
* **Deltas** — compared only against a prior edition that itself had real
  figures; a trend is never fabricated from an insufficient edition.

Every edition carries the snapshot's **Dune auto-run** timestamp — figures
reflect the stamped snapshot time, not real time — and each published
edition's numbers are pinned by a golden test for reproducibility.

## What the report does not claim

No prediction of loss, no statement about any individual wallet, no custody,
insurance, return, or quantum-immunity claims, and no urgency framing.
Signature exposure and dormancy are research heuristics over public on-chain
data. For a single wallet, the right tool is a signed
