Op every Bitcoin address has it's own special seed phrase. The seed phrase is a series of 12 , 18 or 24 words as the case may be, which is generated simultaneously along with the wallet address. The seed phrase in turn is used to create a private key known as the master private key and for the case of an HD wallet, that Master private key is used to generate child keys for other addresses.
Hi, i have created my own private key, public key and seed phrase.
But i can't see the option to add a seed phrase to my private key.
When i created my wallet it asks you to set a type of address and the private key, i created a bech32 address with the private key successfully.
Your public key is generated simultaneously along with the ones I mentioned above. The public key is used to generate your wallet address. You can simply add a new wallet by using the seed phrase or private key of the wallet.
