Digital Euro Association (DEA) MiCAR Tracker

This project tracks issuers of Electronic Money Tokens (EMTs), Crypto-Asset Service Providers (CASPs), and non-compliant entities under the MiCAR framework. The dashboard is a static site (HTML + Tailwind CSS + vanilla JS) served via GitHub Pages that loads its register data from JSON files at runtime.

Architecture

• data/*.json — the registers themselves. emts.json, casps.json, and non-compliant.json are the single source of truth; the page fetches them on load. snapshot.json records the sheet snapshot dates and the last refresh time, and changelog.json records dated additions/removals.
• update-data.js — the scheduled updater. It reads the source Google Sheet (Sheets API when GOOGLE_API_KEY is set, public CSV export otherwise), converts the rows, diffs them against the previous data to extend the changelog and feed.xml (RSS), writes the JSON files, and patches the human-readable "Data as of" dates in index.html's footer.
• .github/workflows/update-dashboard.yml — runs the updater every 6 hours and commits index.html, data/, and feed.xml when anything changed.
• .github/workflows/ci.yml — runs on pull requests and pushes to dev: script syntax checks, updater-marker checks, and data validation.

Data API

The JSON files are stable, publicly served endpoints — feel free to consume them directly:

Register	URL
EMT issuers	https://micatracker.digital-euro-association.de/data/emts.json
CASPs	https://micatracker.digital-euro-association.de/data/casps.json
Non-compliant entities	https://micatracker.digital-euro-association.de/data/non-compliant.json
Change history	https://micatracker.digital-euro-association.de/data/changelog.json
Snapshot metadata	https://micatracker.digital-euro-association.de/data/snapshot.json
RSS feed of register changes	https://micatracker.digital-euro-association.de/feed.xml

Each table on the dashboard also offers CSV export of the currently filtered view.

Configuration

The updater reads feed locations from the CSV_URL, DATE_URL, NON_COMPLIANT_URL, and CASPS_URL environment variables, defaulting to the public Google Sheet exports in config.js. Set GOOGLE_API_KEY (and optionally GOOGLE_SHEET_ID) to use the Sheets API instead of CSV exports; the API path falls back to CSV automatically on errors.

Caching

The updater first fetches the snapshot dates. If neither the EMT nor CASPs snapshot date changed since the last run, the cached JSON under data/ is reused and no full refetch happens. When the snapshot changes, all registers are refetched, diffed for the changelog, and persisted.

Validation

npm run validate:data validates the JSON registers (EMT token counts vs. per-currency totals, required fields on CASPs and non-compliant entries) and cross-checks currency metadata against index.html. CI runs this on every pull request; the update workflow runs it before committing.

Building the CSS

Tailwind output is committed at styles/tailwind.css. After changing markup or tailwind.config.js, rebuild with:

npm install
npm run build:css

Fonts (Inter), icons (Font Awesome), and the flag-emoji polyfill are vendored under assets/vendor/ — the site makes no third-party requests except Umami analytics.
