A wallet for beginners in blockchain - MetaMask wallet

Install MetaMask

Go to MetaMask official website  https://metamask.io/

Click Download (download),   click chrome (Google), and then install the plug-in to Google (MetaMask already supports downloading mobile apps, you can choose according to your preferences).

After the plugin is successfully installed, we can view it from the extension, as shown below:

Register MetaMask Wallet

The sequence is as follows: create wallet - I  Agree - create password - backup mnemonic

The mnemonic must be kept properly (it is recommended to save it in two handwritten copies, it is not recommended to copy and paste it directly on any networked device). If it is lost, your wallet will be lost and your coins will not be recovered. MetaMask is a decentralized wallet. Once the mnemonic is lost, no one can retrieve it.

Use of MetaMask Wallet

1. Your Ethereum wallet address, click to copy.

If you want to see the full address, click "..." on the right, and then click "Account Details" to view it.

Added Binance Smart Chain (BSC) and Huobi Ecosystem (HECO)

Click "Ethereum Network" in the upper right corner of the wallet, pull to the end, click "Custom RPC", and add the network of Binance and Huobi.

1. To add Huobi Eco-chain, fill in the following information:

Network name: Huobi Mainnet

Added RPC URL: https://http-mainnet.hecochain.com

ChainID: 128

Symbol: HT

Screen Manager URL: https://scan.hecochain.com

2. To add Binance Smart Chain, fill in the following information:

Network Name: Binance Smart Chain

New RPC URL: https://bsc-dataseed1.binance.org

Chain ID: 56

Symbol: BNB

Block Manager URL: https://explorer.binance.org/smart

Transfer money from exchanges to on-chain addresses

Whether it is on ETH, BSC or Heco, transactions that occur will be recorded in the blockchain, so any operation must pay a certain Gas Fee.

Different mainnets use different tokens. ETH is used on the ETH mainnet, BNB is used on BSC, and HT is used on Heco.

Therefore, before proceeding, it must be ensured that there are enough tokens in the account address to pay the miner fee.

Take BSC as an example, withdraw BNB from Binance to the account address of MetaMask. Click the red area in MetaMask to copy the account address, and then withdraw BNB to this address in Binance.

Note: This step requires the selection of the BSC mainnet.

The use of blockchain browsers

1. Query the address of the token contract

Taking "BUSD" as an example, enter "BUSD" in the search box and select the token in the drop-down menu.

The area marked in red is the token contract address of BUSD. Copy this address and add it to MetaMask to check the balance of the token in the MetaMask account in real time.

Click "Add Token" and "Custom Token", enter the copied contract address into the "Token Contract Address" column, and then click "Next" and "Add Token" to complete the addition.

2. Query account holding assets

In addition to querying token contract addresses, blockchain browsers can also query tokens held by any address. So you can use this method to query other assets held in our account.

As shown in the figure, enter the account address you want to query in the search box, and click Search.

Click the "Token" column, and in the drop-down menu, you can see all the tokens held by this address.

Click on the token you want to query in the drop-down menu, you can enter the homepage of the token and get the corresponding token contract address. Similarly, copy the area marked in red and repeat the above "add token" operation to add the token to MetaMask.

3. Query account history transactions

In addition to being able to query the tokens held by any address, the blockchain browser can also provide historical transaction information of the address, which is convenient for users to reconcile accounts or follow the transaction behavior of "giant whales".

As shown in the figure, under the "Transaction" column, you can see all the transaction information of the address. Click the corresponding transaction hash to view the transaction details.

The above is the MetaMask registration and usage tutorial for this issue
