 - Module quản lý ví đã có frontend tại `/wallets`, kết nối đầy đủ Wallet API qua TanStack Query, gồm danh sách/chi tiết, tạo/sửa, đặt mặc định, lưu trữ/khôi phục, tìm kiếm, sắp xếp và phân trang. `DELETE /wallets/:id` được thể hiện trong UI là lưu trữ mềm, đúng quy tắc Backend bảo toàn lịch sử.
 - Module quản lý danh mục đã có frontend tại `/categories`, kết nối Category API qua TanStack Query, gồm cây cha/con, tạo/sửa, tìm kiếm, lọc loại/nguồn/trạng thái, sắp xếp, lưu trữ và khôi phục; toàn bộ nội dung có bản dịch Việt/Anh.
 - Module quản lý giao dịch đã có frontend tại `/transactions`, kết nối Transaction API qua TanStack Query, gồm danh sách lịch sử theo ngày, xem/tạo/sửa/xóa giao dịch, lọc nâng cao, sắp xếp, phân trang và đính kèm hóa đơn.
+- Module quản lý chuyển tiền đã có frontend tại `/transfers`, dùng contract `GET/POST /transfers` và `DELETE /transfers/:id` qua TanStack Query; gồm form chọn ví nguồn/đích, validation số dư và hai ví khác nhau, xác nhận trước khi chuyển/xóa, lịch sử có tìm kiếm/lọc/sắp xếp/phân trang và đầy đủ loading/error/empty state. Sau thao tác tạo hoặc xóa, frontend làm mới cache transfer, wallet và transaction để lấy lại số dư do Backend tính toán.
 - Các module ngân sách, tiết kiệm, báo cáo và AI Assistant chưa được triển khai trong frontend hiện tại.
