Field-level summary. The source class describes the kind of source backing each row (see source classes). Live values come from the latest tracked snapshot (1 Jul).

The live KPI strip, supply chart, chain table and activity series above are the on-page market data for EURQ. They are computed by eurostablecoins.xyz from on-chain snapshots across the currently-tracked chains; they are not asserted as the issuer’s own reported figures.

Latest tracked circulating supply: €8.35M · 5 tracked chains · snapshot 1 Jul.

Latest tracked total on-chain supply: €9.68M; identified issuer operational balances subtracted to compute circulating: €1.33M. The per-chain breakdown is exposed through the public API.

The Quantoz transparency page identifies Quantoz Payments B.V. as the issuing entity (Netherlands) [S1]. The same page states that Quantoz Payments B.V. holds a DNB E-money licence in the EEA and frames the stablecoins as MiCAR-compliant. eurostablecoins.xyz records these as Issuer- document facts.

ESMA’s interim MiCA EMT White Paper register independently confirms the EMT notification: Quantoz Payments B.V. is listed with LEI 7245008P1HPUPVM7XL94, De Nederlandsche Bank (DNB) as competent authority, notification date 13/10/2023, and the EURQ whitepaper URL on the register [S5]. The same register row lists Quantoz’s broader EMT portfolio (EURQ, USDQ and additional ticker rows for other currencies that share the same EMI). Narrow scope: covers the EMT white-paper register/notification fact only.

DNB’s public register operates separately. A direct DNB register-entry URL specifically for Quantoz Payments B.V. has not been verified at audit time. That row remains Conflicting or incomplete coverage; the ESMA register entry above covers the regulator-source scope for the EMT notification fact.

ESMA’s interim MiCA EMT White Paper register lists Quantoz Payments B.V. as an Electronic money institution with the EURQ white paper notified to DNB[S5]. The Quantoz transparency page separately describes MiCAR compliance and frames Quantoz stablecoins as e-money tokens under the EU framework[S1]. eurostablecoins.xyz records the ESMA register entry as a Regulator-sourced fact (narrow scope) and the MiCAR-compliance language on the transparency page as Issuer-document fact.

Shown for reference, not a legal opinion. Full context on the MiCA reference page.

The Quantoz transparency page describes Quantoz stablecoins as “backed entirely by a combination of cash deposits, government bonds from the Netherlands, Germany, and US Government” [S1]. The same page references ISAE 3402 financial-reporting controls.

eurostablecoins.xyz records the reserve composition and the ISAE 3402 cadence as Issuer-document facts. The audit firm of record is not named on the transparency page at audit time and is recorded as No public source found. The reserve attestation file URL is not separately hosted as a canonical URL and is also recorded as No public source found.

EURQ is deployed across multiple chains per the registry. The eurostablecoins.xyz tracked chains are the chains shown in the live chain table above, with per-chain supply derived from on-chain totals. Currently tracked: Ethereum, Polygon, XRP Ledger, Xahau, Algorand.

Per the registry, EURQ is deployed on Ethereum, Polygon, Algorand (ASA), Xahau (IOU) and XRPL (IOU). eurostablecoins.xyz reflects on-chain deployments the site currently snapshots.

EURQ peg data shown on eurostablecoins.xyz reflects independent public market price sources where available. A redemption right or issuer statement is not treated as a market price feed. Rolling 7-day and 30-day deviation are computed from the daily EUR price series.

Peg coverage status for EURQ and every other tracked coin, with stale-data thresholds and known gaps, is on data coverage. The methodology behind rolling deviation is on methodology.

The supply chart and the mint/burn and transfer-volume series above are the historical context for this page. eurostablecoins.xyz does not annotate specific historical movements without an attributable source.

Where historical rows carry a smaller per-chain chain set than the latest snapshot, the "Supply by chain" chart shows a muted, dashed Unattributed (partial historical chain coverage) band on top of the per-chain stack so the stack always sums to the row’s known circulating supply.

eurostablecoins.xyz exposes EURQ data through the public v1 API. All endpoints return JSON, are CORS-enabled and are stable under /api/v1/*.

• /api/v1/coins/eurq — EURQ metadata and current state.
• /api/v1/supply/eurq — latest EURQ supply snapshot.
• /api/v1/history/supply/eurq — daily EURQ supply history.
• /api/v1/peg/eurq — latest EURQ peg metrics.
• /api/v1/holders/eurq — latest EURQ holder snapshot.

Every endpoint returns a source field and a timestamp; cite both when reproducing values. Full contract / endpoint reference is on /docs.

Supply, market share, chain distribution, peg data, historical series, holders, mint/burn and transfer-volume on this page are computed by eurostablecoins.xyz from on-chain snapshots. Values refresh on cron cadence and are not real-time tick-by-tick.

Issuer identity, DNB EMI licensing claim, reserve composition and ISAE 3402 cadence reference are drawn from Quantoz’s public pages [S1][S2][S3][S4].

Specific gaps on this page:

• ESMA EMT White Paper register entry — substantiated (Regulator-sourced fact). Quantoz Payments B.V. is listed on ESMA’s interim MiCA EMT register with DNB as competent authority and the EURQ whitepaper URL on record [S5].
• DNB public register direct entry — not independently cited (Conflicting or incomplete coverage). The ESMA EMT register entry above lists DNB as the competent authority; the per-country register-entry row is left as CIC for transparency.
• Auditor of record — not named on the transparency page at audit time (No public source found). Transparency page references ISAE 3402 controls without identifying the audit firm.
• Reserve attestation file URL — not separately cited on this page (No public source found).
• Launch-announcement news URL — the registry-stored URL quantoz.com/news/quantoz-launches-usdq-and-eurq returns HTTP 404 at audit time and is NOT cited on this page.
• Historical per-chain attribution — partial for periods before every currently-tracked chain was snapshotted. The "Supply by chain" chart displays an explicit "Unattributed (partial historical chain coverage)" band so the stack visibly sums to the row’s circulating supply.

Is EURQ a MiCA e-money token?

ESMA’s interim MiCA EMT White Paper register independently confirms the EMT notification: Quantoz Payments B.V. is listed with LEI 7245008P1HPUPVM7XL94, De Nederlandsche Bank (DNB) as competent authority, notification date 13/10/2023, and the EURQ white-paper URL on the register. eurostablecoins.xyz records the ESMA register entry as a Regulator-sourced fact (narrow scope: EMT white-paper register/notification fact only). The Quantoz transparency page separately describes MiCAR compliance and DNB EMI licensing — recorded as Issuer-document fact. The DNB public register direct entry for Quantoz Payments B.V. has not been verified at audit time and is recorded as Conflicting or incomplete coverage.

Where can I find EURQ reserve attestations?

The Quantoz transparency page references ISAE 3402 financial-reporting controls but does not name a specific audit firm and does not host a single canonical attestation file URL. eurostablecoins.xyz records the cadence as Issuer-document fact, the auditor name as No public source found, and the attestation file URL as No public source found.

Why might EURQ supply differ between eurostablecoins.xyz and other trackers?

Different trackers may apply different methodologies, snapshot timing, chain coverage and circulating-supply assumptions. eurostablecoins.xyz tracks EURQ across Ethereum, Polygon, Algorand, Xahau and XRPL where on-chain data is available. Raw on-chain totals and the per-chain breakdown are exposed through the public API.

Sources are grouped by source class. The Regulator / register sources block cites ESMA’s interim MiCA EMT White Paper register, which lists Quantoz Payments B.V. with DNB as competent authority. The DNB public register direct entry has not been verified directly; see Data coverage and limitations above for the residual gap.
