- 24/7 composite
- Median of per-venue median prices across every venue printing the name, rolled to 1-minute bars. No venue weighting — reported volume can be washed, so it never weights anything.
- Basis / depeg
- Signed spread of each instrument vs the latest official reference close, in bps. Spot-backed tokens beyond their threshold are flagged as depegs. Names with no US listing show n/a — undefined, honestly, never zero.
- Session hours & countdowns
- One NYSE calendar (holidays, half-days, DST-correct), mirrored byte-for-byte between the ClickHouse products, the API (/v1/calendar), and this dashboard. Never a hardcoded weekend check.
- Exposure
- Spot AUM = on-chain token supply × live price. Perp OI = open notional marked to the tape. CEX token supply cannot be measured, so CEX exposure is NOT summed in — its 24h traded volume is reported separately, labelled as such.
- Liquidity
- Walked from real order-book snapshots: resting notional within ±5/10/25/50 bps of mid and estimated slippage for a $100k order. Bookless venues simply do not appear — coverage is sparse-honest, never extrapolated from reported volume.
- Implied borrow
- Perp funding annualized per venue cadence. The implied side only — the tradfi sec-lending baseline is a stated gap until that feed is sourced.
- Corp-action forensics
- Reference splits from the licensed feed vs each venue's declared on-chain supply events and observed price ratio. A venue that keeps printing at pre-split scale gets a public verdict, not a silent correction.
- Tracking error
- RMSE / mean / stdev of per-minute basis vs the reference — fidelity over time, not a point-in-time spread. Consistent index-scale bias is flagged (SCALE?), never silently rescaled.
- Flows & holders
- Mint/burn and supply deltas measured from transfer logs, in exact token units. Holder counts are raw; dust-adjusted holders and concentration are Phase 4 and will be labelled when they land.
- Freshness
- Every venue's capture lag is itself measured and published (/v1/freshness). Stale venues are flagged in red wherever their numbers appear — nothing on this site is silently frozen.
