It is necessary to make sure that the user himself chooses to create his own wallet from a seed phrase of 12 words or 24 words. And exactly the same must be done so that the user can import his seed phrase of 12 words or 24 words. There are currently very few wallets that support the creation and import of a 24-word seed phrase, so if you do not make a choice in Klever Wallet, users simply may not find a third-party application to restore their wallet. And experienced users, knowing about these further problems, will simply not take the risk and use Klever Wallet.
