# 3️⃣ **Add User Model and Postgres Integration** * ✅ Use `Prisma` (recommended for Postgres) or any ORM: * Table: `User { id, address, created_at }` * ✅ On first login: * Check if user exists by `address`. * If not, insert into the `User` table. * ✅ Add adapter to hook NextAuth to the database. ---
