First of all, I need to share some science with you. The wallet here is not actually a wallet in a broad sense, but a definition in the blockchain. It is not used to put money, but to Install the secret key. On the blockchain, as long as you have the key, and then match it with the all-inclusive address, you can extract the virtual currency inside and use it. Therefore, the wallet address and key are very important, and they are often packaged together.

First, the concept of wallet First, let’s understand the wallet. What needs to be clarified is that the wallet is not actually a tool for storing money, but a tool for storing keys (private keys and public keys). The key can have control over the digital currency on the corresponding address. Private key: The user uses the private key to sign the transaction, thereby proving that he has the right to output the transaction. The transaction information is not stored in the wallet, but in the blockchain. Public key: used to generate addresses and store transactions. Information is generated by the private key through an asymmetric encryption algorithm. Wallet address: It is a 42-digit hexadecimal hash value string starting with a double letter (representing the currency). The address of ETH is a 42-bit hexadecimal hash value string starting with 0x. If a wallet is compared to a bank card, then the wallet address is the bank card number.

Second, how to use the wallet. There are many digital wallets on the market currently,

Such as imToken, myetherwallet, Kcash, parity, Metamask, Jaxx, etc. Choose a wallet you like. It is recommended to choose imToken. Here we also use imToken as an example: Download an imToken APP in the application market, click "Create Wallet", and give the wallet a name and password. Please note: remember the password yourself. imtoken will not remember your password. If you forget your password, it cannot be retrieved! ! So forgetting your password means losing all the currency in your wallet! ! It is best to copy it down by hand and keep it properly to prevent loss caused by network transmission and hacker attacks. This is very, very important. Remember to click Create Wallet. After the wallet is created, we need to back up the wallet. Wallet backup is used to restore the wallet settings if the program is deleted or the phone is stolen.

There are two ways: backup mnemonic or backup keystore. The mnemonic phrase is 12 randomly generated words. You can copy this and put it in a safe place. Then copy a copy in order and put it in a safe place. You can understand this mnemonic phrase as another form of the private key. , based on which the wallet can be restored. For example, if you accidentally delete the imtoken application, or your phone is missing, you can use this mnemonic to restore the wallet. The keystore is a string similar to the picture above. You can back up this keystore and use this keystore to restore your wallet after deleting it. After practicing a few times, you can become familiar with the wallet. At this point, the wallet is created. On your wallet page, click on the right side of the address bar to get the address of your wallet. (3) Withdrawing coins from the exchange to the wallet We take the exchange gate.io as an example to demonstrate how to withdraw ETH coins into the wallet. Log in to gate.io, click ETH, and this interface will appear. The red box inside is the wallet address to be transferred. (4) Transfer between wallets. After entering the wallet, select the amount area: the transfer page will be displayed: you can enter the account number yourself, or you can use the swipe in the upper right corner: press next and enter the password to transfer
