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.
