Did you know this about mnemonic seed phrases?

Anyone with a modern crypto wallet has been presented with a mnemonic seed phrase in order to backup your wallet.

Some may be familiar enough to know those words come from a BIP39 change but did you know the last word contains checksum data for the entire word set? This means not all combos of words is even a valid mnemonic. A beautiful consequence of this is that nobody can do something stupid like customize their mnemonic by picking the first 24 words of the official word list which would he very easy to guess by someone trying to brute force low entropy mnemonics.

Humans are not random so picking your own words is never recommended. You can look up the proper way to derive a mnemonic by referencing this GitHub repository:
