Problem statement
In the world of the internet, user experiences have become increasingly important.
However, where there is profit to be made, scams tend to proliferate.
These scams can take various forms, including fake accounts, financial losses,
and breaches of privacy. Unfortunately, trust between users has weakened compared to the past.
Goal
The main goal of this project is to improve the safety of the selling cycle between “user to user”.
Improvement
In the world of the internet, user experiences have become increasingly important.
However, where there is profit to be made, scams tend to proliferate.
The improvement will focus on enhancing the function to help users feel safer.
By adding an optional feature, users will be able to determine the type of user they are
interacting with, enabling them to make an informed decision on whether to initiate a conversation.

additional personal information compared to their previous enrollment.
2.selecting the red tick, they need to submit the requested information.
3.Once the information is submitted, users are required to wait for a period of 2-4 working days.

Best Seller Reward
User Flow

The user flow, whether for buyers or sellers, begins with accessing the user's profile.
Within the user's profile, there is a section dedicated to user reviews.
Within this section, users have the opportunity to unlock the "Best Seller" reward.
However, it's important to note that if users do not have a sufficient number of
positive reviews, they will not be able to unlock this reward.
Appoiment and Tracking System
User Flow
Face to Face Appoiment

The user flow involves users interacting face-to-face.
After one user makes an offer to another user, if the offer is accepted, a reminder will be provided to the user to
choose whether to set up an appointment reminder
or send it as an email. Once the decision is made,
the user can add it to their own calendar or set it up as a system reminder.
Tracking System

The user flow in the tracking system involves one user sending
a product to another user. Both users have the ability to make
offers, and if an offer is accepted, they proceed to add the necessary details for delivery.
