1. Introduction to BNB Smart Chain

The realm of cryptocurrencies and blockchain technology continues to grow, as new systems and platforms emerge on a regular basis. Among these, the BNB Smart Chain has recently gained significant traction. The BNB Smart Chain operates as a parallel blockchain to Binance Chain, offering an environment in which developers can effortlessly and effectively build and deploy smart contracts and decentralized applications (dApps).

In this guide, we will explore how to utilize MetaMask, a widely-used Ethereum wallet and browser extension, in conjunction with the BNB Smart Chain. Covering everything from setting up the network to engaging with BNB Smart Chain dApps, this all-encompassing tutorial will enable you to smoothly navigate the world of MetaMask and BNB Smart Chain.

2. Installing the BNB Smart Chain on MetaMask

MetaMask is an Ethereum-based wallet and browser extension that enables users to interact with the Ethereum blockchain and manage their digital assets. To use MetaMask with the BNB Smart Chain, you need to add the network to your wallet. There are two ways to do this:

a. Automatic

1. Open MetaMask and click on the network selection dropdown at the top of the extension.

2. Click “Add Network” under to Ethereum Mainnet.

3. Click “Add” next to “BNB Smart Chain”.

4. Click “Approve”.

5. Click “Switch to BNB Smart Chain”.

b. Manual

If you prefer to set up the BNB Smart Chain manually or encounter a situation where the automatic setup is not available, follow these steps:

1. Open MetaMask and click on the network selection dropdown at the top of the extension.

2. Scroll down and click on “Add network”.

3. Select “Add a network manually”.

4. Enter the following details:
Network Name: BNB Smart Chain (previously Binance Smart Chain Mainnet)
New RPC URL: https://bsc-dataseed.binance.org/
ChainID: 56
Symbol: BNB
Block Explorer URL: https://bscscan.com/

5.Click “Save” to add the BNB Smart Chain to your MetaMask wallet.

3. Adding and Managing Tokens on BNB Smart Chain

To add and manage tokens on the BNB Smart Chain, follow these steps:

1. Open MetaMask and ensure you have selected the BNB Smart Chain.

2. Click “Import Token” at the bottom of the extension.

3. Enter the “token contract address”, “token symbol”, “token decimal” manually and click “Add custom token”.

4. Click “Import token” to complete the process.
You can now view and manage your BNB Smart Chain-based tokens within MetaMask.

4. Discovering Contract Addresses on BscScan.com

BscScan.com is a block explorer for the BNB Smart Chain that allows users to search and analyze transaction data, addresses, and contract information. To find a contract address for a specific token or dApp on BscScan.com, follow these steps:

1. Visit https://bscscan.com/ and locate the search bar at the top of the webpage.
   
2. Enter the token or dApp name in the search bar, and select the appropriate suggestion from the drop-down menu. If you cannot find the token or dApp by name, you can also search for it using the contract creator’s address or the transaction hash of a transaction involving the token.
   
3. Once you have navigated to the token or dApp’s page, you will find the contract address displayed prominently. The contract address is a unique identifier for the token or dApp and is typically a 42-character alphanumeric string that starts with ‘0x’.
   
4. You can now copy the contract address and use it to add the token or interact with the dApp through MetaMask or other compatible wallets.

5. Sending and Receiving Cryptocurrencies on BNB Smart Chain

Sending and receiving cryptocurrencies on the BNB Smart Chain using MetaMask is quite straightforward. To send or receive tokens:

1. Open MetaMask and ensure you have selected the BNB Smart Chain.
   
2. To send tokens, click “Send,” enter the recipient’s address, the amount you wish to send, select the appropriate token, click “Next”. Confirm the transaction details and click “Confirm.”
   
3. To receive tokens, click on under your account name and copy your BNB Smart Chain address. Share this address with the sender to receive tokens.
   

6. Interacting with BNB Smart Chain dApps

With the BNB Smart Chain set up on MetaMask, you can now interact with various BNB Smart Chain dApps. To do this:

1. Visit the dApp website and ensure you have selected the BNB Smart Chain on MetaMask.
2. Click on “Connect Wallet” or a similar button on the dApp website.
3. MetaMask will prompt you to connect your wallet to the dApp. Review the permissions and click “Connect.”
4. Once connected, you can start interacting with the dApp by following the instructions provided on the website. This may include approving transactions, staking tokens, or participating in various DeFi protocols.
5. When interacting with the dApp, always double-check the transaction details before confirming, ensuring the correct amounts and addresses are used.

7. MetaMask best practices

Here are some best practices for using MetaMask:

• Only use your wallet on your own computer, not one that other people use too.
• Use the wallet on a computer instead of a phone because it’s harder for bad people to steal from a computer.
• Keep a secret backup of your wallet’s special words, called a seed phrase, somewhere safe.
• Use a special app like Lastpass or KeePass to save your password and seed phrase.
• Write your password and seed phrase on paper or in a book you love and will never lose.
• Split your secret password and phrase into 3 parts and hide them in different places.
• Make your password extra safe by adding extra words to it and remembering those words.
• Use a password app to make a really strong password.
• Be careful with what you add to your internet browser, and turn off things you don’t use.
• Use a special computer program to check for bad software that tries to steal your stuff.
• Clean your internet browser’s history and cookies often.
• Lock your Metamask wallet when you’re not using it.
• Turn off the Metamask feature in your browser when you don’t need it.
• If you have lots of money in your wallet, make different accounts and spread the money between them.
• Move some money out of your wallet regularly.
• Never tell anyone your secret phrase or share it online. If someone knows it, they can steal your money.
• Keep your computer or phone safe because your password only works on your own device.
