Hello,
from various information sources, by summary concludes the current seed phrase storage as best:
2 of 3 multisig.
My understanding is a seed phrase will have 24 words.
These 24 words are then engraved onto 3 stainless steel hexkeys, so when 2 of these hex keys are brought together, the 24 words are revealed.
Then the user needs to enter the passphrase to fully recover the wallet.
The seed phrase is very important for everyone to secure to avoid someone to to get access to his wallet, because once a person mistakenly lose his seed phrase what ever he have in his wallet can definitely gone since immediately the scammers get access to your wallet they will swap everything from your wallet.
There are some people that they can create a wallet in the same device and the same time store them in the same place how will come and identify the first and second, I know for those that are engaged in the crypto aspect for a long time knows what their doing unlike the newbie’s that they don’t know where to start.
