Exchange Validator is a free Chrome add-on developed by LuckyPigeon. It falls under the category of Browsers and is listed as an Add-ons & Tools subcategory. This add-on aims to protect users from being tricked by phishing exchange platforms with just one click.

By enabling and pinning the add-on, users can easily determine the safety of a cryptocurrency exchange platform. Once inside the exchange, users can click on the green checkmark icon located in the top-right corner of the browser. If the website is flagged as a potential phishing site, the icon will turn red, accompanied by a text prompt stating "This exchange is unsafe."

It is important to note that this add-on serves as a helpful reminder and may not include all newly established exchanges. It should not be solely relied upon as the only validation tool. Developing the habit of cross-checking information from multiple sources is the best way to prevent falling victim to phishing sites. Users are encouraged to exercise caution and use this add-on as an additional layer of security.
