March 28, 2022 View Original Today we will tell you how you can import private keys between wallets.
✅ How does it work?
When importing a private key, it is not the coins themselves that are transferred to the new wallet, but rather combinations of symbols - the private key. Those. all funds remain at your old wallet address. During import, you simply duplicate the public and private key into another wallet and can manage everything from there.
✅ For what?
🔐 For your convenience and safety.
1️⃣ Let’s imagine that you have 3 wallets: MetaMask, TrustWallet and SafePal. You can import private keys from TrustWallet and SafePal wallet into your MetaMask. In this case, you do not need to log into each wallet separately to access your tokens. You can manage transactions, see your balance, and connect to websites from your MetaMask interface.
If you have several MetaMask wallets, you can also import all private keys into one and manage all wallets from one.
2️⃣ Another plus of using such a scheme. For example, you have funds on TrustWallet and SafePal, but these wallets cannot be connected on certain sites. MetaMask is accepted by all platforms. In order not to specifically transfer your tokens to MetaMask and not spend money on commissions, you import private keys from the necessary wallets into it. After this, you will be able to connect to sites and have access to your funds from all wallets in one MetaMask.
3️⃣ If an attacker recognizes your seed phrase, he will not see your imported wallets in the interface, and therefore will not be able to steal them.
You can make an empty MetaMask wallet that will serve as a wrapper for imported fund wallets. In the event of a leak of the seed phrase, access will only be to the shell wallet in which you do not have funds.
We will analyze the whole process step by step using the MetaMask wallet as an example. Go to MetaMask and click on the 3 dots in the upper right corner. Select “Account details”
Click “Export private key”
Enter your MetaMask wallet password.
Copy the private key.
Let’s go to the wallet into which you will import the private key. Click on the icon in the upper right corner and click “Import invoice”
Insert your private key and click “Import”
The imported invoice will appear in your “my accounts” menu marked “imported”. You can rename it by clicking the pencil in the “Account Details” menu.
Keep your seed phrase and private key in a safe place.

Щоб перетворити мнемоніку на приватний ключ, вам спочатку потрібно згенерувати початкове значення з мнемоніки за допомогою функції похідного ключа, наприклад PBKDF2 або BIP39. Початковий код потім використовується для створення головного ключа за допомогою ієрархічного детермінованого (HD) алгоритму генерації ключів, такого як BIP32.
Потім головний ключ можна використовувати для отримання закритого ключа, який є 256-бітним числом, представленим у вигляді шістнадцяткового рядка. Цей закритий ключ можна перетворити на ключ WIF (формат імпорту гаманця) для біткойнів або безпосередньо використовувати для створення відкритого ключа та адреси для Ethereum.

Щоб створити біткойн-адресу, закритий ключ потрібно хешувати за допомогою алгоритмів SHA-256 і RIPEMD-160, а потім закодувати за допомогою Base58Check. Це створює унікальну адресу, яку можна використовувати для отримання біткойнів.
Щоб створити адресу Ethereum, приватний ключ використовується для створення відкритого ключа, який є точкою на еліптичній кривій. Цей відкритий ключ потім хешується за допомогою алгоритму Keccak-256, і отриманий хеш використовується як адреса.
