**Severity:** Medium **Type:** Bug **Scope:** Donations, Users **Labels:** `bug`, `security`, `help wanted` ### Description Both the synchronous and asynchronous export paths emit a hardcoded `0.00` USD equivalent: - `UsersService.exportUserDonationsAsCSV` (`src/users/users.service.ts`, line ~415). - `ExportProcessor.handleDonationExport` (`src/users/export.processor.ts`, line ~58). The comment in each location acknowledges this is a placeholder ("USD equivalent: fetched from price cache in production"). Two failure modes persist today: 1. Users downloading the CSV for tax/accounting will see a `0.00` value and may trust it. 2. If a future consumer (analytics dashboard, partner integration) ingests the CSV preemptively, the integration will be biased. ### Recommendation - Drop the column entirely until a real price-oracle integration is added, or rename it to `Quote: pending`. - When ready, integrate a price oracle (Stellar Horizon `/order_book` snapshots, CoinGecko, or a self-hosted oracle service) and cache quotes with TTL by asset. - Document the absence in `README.md` so external integrators are not surprised. ---
