I see what is happening here. It seems that you are wrapping yourself in some technical details about mnemonic phrases and bip44 paths.
To clarify, a mnemonic phrase is a sequence of words or characters that serve as a password or encryption key for a cryptographic wallet, such as metamask. The phrase is used to derive a private seed key that can be used to manage funds in the wallet.
In the case of BIP44 (Boyerdinger’s private key format), a mnemonic phrase is used to derive the public key from the private key. This allows users to store and manage their private keys using a mnemonic phrase.
Now, in relation to your question: How is my wallet determined by the Mnemonic phrase?
When you create a mnemonic phrase to a BIP44 path, it is not directly related to the determination of the metamask portfolio address. Here’s why:
- Mnemonic phrases are used for storage : The mnemonic phrase is used to store the private key safely using a BIP44 format. This means that the mnemonic phrase is not directly linked to the address of the metamask portfolio.
- Metamask uses seed wallets
: Metamask supports seed wallets that use a seed derived from a mnemonic phrase to manage funds. The seed is then used to derive other keys, such as the private key and the public key (which is the one you are referring to as a portfolio address).
- Wallet addresses are seeds, not mnemonic phrases : When you create a mnemonic phrase to a BIP44 path, it is used to generate a seed. This seed can be used to derive other keys, including the private key and the public key (the portfolio address). The address of the wallet is obtained by concatenating the seed with the parameter
address_indexon the BIP44 path.
In short, the mnemonic phrase you create for a BIP44 path is not directly related to the determination of the metamask portfolio address. The address of your wallet is derived from the seed generated by the mnemonic sentence and concatenate with the parameter address_index address on the BIP44 path.
