<div align='center'>Wellchange Holdings Company Limited

Resale of Up to 100,000,000 Class A Ordinary Shares

by the Selling Shareholders</div>

This prospectus relates to the offer and resale,
from time to time, by the selling shareholders identified in this prospectus (the “Selling Shareholders”), of up to 100,000,000
class A ordinary shares, par value US$0.00005 per share (“Class A Ordinary Shares”) of Wellchange Holdings Company Limited
(the “Resale Shares”), a Cayman Islands exempted company with limited liability. Our Class A Ordinary Shares are listed on
the Nasdaq Stock Market under the symbol “WCT.” On December 3, 2025, the last reported sale price of our Class A Ordinary
Shares on the Nasdaq Capital Market was $0.226 per share, and as of the date of this prospectus, we had 145,265,000 Class A Ordinary Shares
including 100,000,000 Resale Shares and 8,000,000 Class B Ordinary Shares issued and outstanding.

We are registering the Resale Shares on behalf
of the Selling Shareholders, to be offered and sold by them from time to time. We are not selling any securities under this prospectus
and will not receive any proceeds from the sale of the Resale Shares by the Selling Shareholder pursuant to this prospectus.

We are registering the Resale Shares pursuant
to the Selling Shareholder’s registration rights under the securities purchase agreement the Company entered with certain investors
on September 9, 2025 (“2025 September SPA”). Our registration of the Resale Shares does not mean that the Selling Shareholder
will sell any of the securities offered hereby. The Selling Shareholder may offer and sell the Resale Shares in a number of different
ways and at varying prices. We provide more information about how the Resale Shares may be sold in the section entitled “Plan of Distribution.”

Our issued and outstanding share capital is a
dual class structure consisting of Class A Ordinary Shares and class B ordinary shares of a par value of US$0.00005 each (the “Class
B Ordinary Share”). Holders of Class A Ordinary Shares and Class B Ordinary Shares shall at all times vote together as one class
on all matters submitted to a vote by the shareholders at any general meeting of the Company.
