--+      ✅ 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.
