Data Sources and Methodology
Quick Answer
Our pages combine original-source documentation with dated market, network and fund observations. Figures retain their units and source dates, missing values are not replaced with zero, and invalid historical observations are excluded from charts. Use the references on each page to check the original context. Collection time and valuation time are different.
Market data
Market values are normalized from CoinMarketCap and retained with their observation and collection times. Home, Markets, Metrics and Charts use the same published dataset.
Reloading a chart reads that shared dataset rather than independently collecting a new quote. Daily observations are not a candlestick or streaming feed.
Network data
ZecStats supplies the observed network height, supply and source-defined pool balances. Shielded totals include the named shielded pools, not Transparent or Lockbox.
Numeric and date checks are applied before charting; invalid or incomplete observations are excluded from computed totals. The site does not run an independent node.
Fund data
ZCSH issuer observations retain their valuation date and distinguish GAAP from non-GAAP amounts. Current fund data is not inferred from SEC filing dates or missing fields.
Premium calculations use matching-date, user-entered market price and NAV: (market / NAV − 1) × 100.
Protocols and wallets
A protocol proposal, software release and activated network rule are different states. Wallet support is specific to its platform, version and supported receiver.
Publisher statements are linked to their source and should not be read as an independent device or security audit.
Dates and source versions
Retrieval time records when a source was collected, not when its market value or document became effective. Source URLs, saved versions and hashes let readers inspect the basis of a statement.
Missing dates are not interpolated to make a smooth chart.
Sources and Methodology
Page updated: . Source observation dates remain separate.
Methodology and technical limitations
Methodology: historical observations and technical scope
The initial fund reference is a provider-extracted issuer observation valued on 2026-08-28, not a current daily feed. February ZCAP results, the August announcement and September participation summary are separate records; the September source reports 135 of 198 members without establishing a winning option here. ZIP 258 describes a protocol proposal, while publisher release text describes implementation. Trezor vendor documentation distinguishes transparent support from shielded support; this site does not certify individual firmware or device behavior. Daily fund collection now also checks the canonical Grayscale product page through an extraction provider, with compatible valuation dates and NAV/share/AUM and holdings/share validation. Historical observations remain dated; neither repeated retrieval nor a document date becomes a new fund valuation.
Source dates describe the referenced observation or document, not a live price. How data is checked · Corrections
