Migrate from MintDefense to Pocket Universe: Complete Guide
Migrate from MintDefense to Pocket Universe now. Complete migration guide for yearly licenses, lifetime NFTs, and free users. Upgrade instructions included.

ACTION REQUIRED: MintDefense Migration
MintDefense has evolved into Pocket Universe, an even more advanced protection system, and you must migrate to it to remain protected.
By the end of this month November 2024, the MintDefense extension will stop functioning and you won’t be protected.
You must switch to the new Pocket Universe extension and follow the steps below according to your MintDefense license type.
READ CAREFULLY according to the license you use.
NOTE FOR ALL LICENSE TYPES: If you were using our Secure RPC, you must update it in your wallet. After migrating to the new extension, you can find the new details by clicking on the extension, Settings icon, “Add Secure RPC”.

If after doing the steps above it says your yearly license is not found, it’s likely it expired and you only need to uninstall the MintDefense extension and install the Pocket Universe extension.
If you successfully migrate, your yearly license will expire 1 year after the date of your payment. You will be automatically switched to Pocket Universe Pro and won’t lose any protection.
Yearly payment is not required in the new Pocket Universe extension.
Lifetime NFT Licenses

Before starting, disable Starkey wallet on your browser. If you don’t, MetaMask won’t pop up for you while migrating.

To migrate without your NFT to other devices (after performing the steps above), please do the following:
- Ensure you have version 1.1.2 installed (if not, force an update via the extensions tab on Chrome toggling Developer Mode on if needed)
- In the extension instance you migrated to NFT, go to Settings -> App Info -> and choose “Export.” This will copy your instance key to your clipboard.
- In the devices you wish to use your NFT license on, choose “Import” on the same screen and paste the key. This will sync this new instance with your exported NFT instance.
NFT minting is possible only until the end of this month November 2024, over at https://app.kerberus.com/.
After that, minting won’t be possible for an undetermined amount of time until we deploy a new system.
For support, please open a ticket at our Discord, or send an email to support@kerberus.com from the email associated with your MintDefense license.
