A public key is represented as an alphanumeric string , just like the private key. Both are usually displayed in hexadecimal format.


To add to this, if there’s ever a need to ensure that close relatives are aware of your investments in case of unforeseen circumstances, it’s much safer to use a 2-of-3 multisig wallet instead of directly sharing your private key. In such a setup, each participant holds one key, and any transaction will require at least 2 out of 3 signatures. This protects against abuse, prevents a single person from acting alone, and keeps the private key itself uncompromised.
