+      🔍 BACKEND TESTING COMPLETED - CRITICAL SUPABASE CONFIGURATION ISSUES FOUND
+      
+      ✅ WORKING:
+      - Blockchain Balance API: Functioning correctly with mock data (HEZ/PEZ balances)
+      
+      ❌ CRITICAL FAILURES - ALL AUTH ENDPOINTS:
+      - Supabase Auth signup works (creates auth user)
+      - BUT profile data insertion fails with RLS policy violation
+      - Backend using anon key instead of service role key for server operations
+      - Users table missing required columns (first_name, last_name, etc.) - PGRST204 error
+      - All auth endpoints (signup, signin, profile) are blocked by these issues
+      
+      🚨 ROOT CAUSE: Supabase configuration problems
+      1. Backend needs SERVICE ROLE KEY for server-side operations (not anon key)
+      2. Users table schema incomplete - missing columns: first_name, last_name, phone, etc.
+      3. RLS policies prevent anon key from inserting user profile data
+      
+      REQUIRES IMMEDIATE ATTENTION: Use websearch tool to research Supabase service role key setup and users table schema creation.
