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 Readiness Packet — every report edition links there.
