Mainchain - Supported Browsers


Why is it important to use the latest internet browser?

Two key reasons for keeping your internet browser up-to-date.

  • Your own safety and security, outdated browsers may have vulnerabilities.
  • Provide the best browsing experience.


Mainchain is developed to make the most of the latest technologies, this means that older browsers may not be supported, and some features will be unavailable.

What does this mean for you?
