# Snowflake — Seiche Reference FX evaluation share

Prepared 11 October 2026 IST. State: **packet ready full account required**. No new application, agreement or message was sent by this preparation work.

## Proposed recurring use

A treasury/data team joins a narrow table of daily EUR reference observations to its own research tables. The first offer is a free evaluation share with explicit source and vintage columns; its purpose is testing data ingestion and recurring use.

## Entry and prepared fields

Official entry: https://app.snowflake.com/

- Provider name: LiquiLens.
- Proposed listing: Seiche Reference FX — dated EUR observations.
- Category: Financial / reference data, if available in the current portal.
- Description: Daily ECB reference observations for USD, GBP, JPY and INR per EUR, delivered with source credit, units, retrieval dates and current-vintage limits. Original data is freely available from the ECB. Seiche presents the values without interpolation or currency conversion.
- Data contract: reference-fx-sample.schema.json and dataset-factsheet.md.
- Sample: reference-fx-sample.csv; four series, twenty observed dates each.
- Evaluation questions: which date is latest per currency, which retrieval clock produced it, and which observation dates are absent?

The downloadable sample is limited to four ECB EUR reference-FX series. Broader LiquiLens institution and Undertow liquidity tools are separate source-bound research services. No dataset sample grants rights over unrelated sources. Customer counts, revenue, certifications, SLA commitments and named reference clients are not established by this packet.

## Remaining gate

Requires a full Snowflake account, provider privileges, accepted provider terms and approved profile. Trial accounts cannot publish on Marketplace. The official paid-provider billing-country list checked in this pass omits India; do not assume LIQUILENS PRIVATE LIMITED can sell a paid listing. Free provider eligibility, sharing/replication costs and terms still require account review.

No native share, native application or Snowflake execution was created or tested. Dataset first_available_at remains NULL; a current-amended series must not be advertised as point-in-time backtest data.

## Evaluation assets

[Dataset factsheet](dataset-factsheet.md) · [80-row CSV sample](reference-fx-sample.csv) · [JSON sample](reference-fx-sample.json) · [Sample verification](sample-verification.json) · [Reference-FX review](sample-report-fx.md) · [Coverage and vintage review](sample-report-coverage.md).

A useful first evaluation is one dated note retained by an independent analyst. A second-day return and the analyst's assessment of usefulness are tracked separately from a successful request or an accepted listing.
