Metamask is a cryptocurrency wallet software, originally used to interact with the Ethereum blockchain. Currently, Metamask wallets can integrate a lot of different blockchains. These include the App wallet version for Mobile and the Chrome app extension, also known as the Extension extension.

Currently, the Metamask wallet can be considered the standard wallet, the most popular today. Used primarily to interact with most blockchains, and also used to test networks.


Buy Crypto Through Debitcard: Users can buy crypto through Wyre in USD. Crypto will then be transferred to the wallet on Metamask.

Send & receive money: After connecting and creating a wallet on Metamask, users can send and receive crypto assets on the wallet by copying the wallet address sent to others.

Swap Crypto: If you want to buy and sell assets on your wallet, there is no need to connect to the AMM, because on Metamask there is now a swap feature integrated.

Intuitive user interface: Its user interface is quite beautiful and intuitive to use.

Multilingual support: A variety of languages including Vietnamese.

HD wallet: MetaMask is an HD wallet, so you don’t need to worry about backing up each pair of public/private keys. Instead, rely on just 12 seed phrases during setup. But you should remember to keep that phrase carefully, if you lose those 12 words will lose all the funds that are stored.

Custom fee: Gas price and gas limit charges can be adjusted.

Add ERC-20 tokens: Add or hide comfortable ERC-20 tokens.  

Network options: Advanced developers and users developing DApps over the Ethereum network can also access various demos through the MetaMask wallet.



  • Easy to use, friendly interface.
  • Swap integration should not need to connect to other AMM, saving time.
  • As a popular wallet extension, almost all new projects are automatically integrated.
  • Customize the gas fee, helping users customize the speed of the transaction completed.
  • Multi-blockchain integration.


  • Swap fees are quite high.
  • Unable to log in to multiple wallet addresses, each time you want to log out another wallet address, you have to log out.
  • Without automatically updating asset data, users must integrate manually. This results in no asset show if the user does not know the contract of that asset.


Metamask is a non-custodial wallet, i.e merely a place to log in to a wallet. In addition, this is currently one of the most popular wallets in Crypto, so it is highly unlikely that Metamask will cause damage to your assets.

However, there are still cases of loss when logging in to Metamask, be it because the user exposed a private key, or the malicious code installed in the computer read private key while operating on the wallet, … Therefore, it is necessary to be careful in protecting your computer, your phone.

To load ETH or ERC-20 tokens into your MetaMask wallet from another exchange or wallet. You just need to send the address of the account you want to receive the token in MetaMask.

* Note: For Metamask wallets, the ERC-20 network always defaults, transaction fees for receiving coins/tokens usually range from 20-50 USDT, depending on the volume and time of the transaction. In your Metamask wallet, you must always have a few ETH coins available for transaction fees.  Just 2 extremely simple steps as follows you can load the token into the wallet:

Step 1: Access the extension and sign in to open the wallet

Step 3: After adding the token successfully, you move the mouse through the account name, which will display the words “Copy to clipboard”. Tap it to copy your account address, and then send it to the transfer. Or you can do the same on the exchange where you want to transfer the token to the MetaMask wallet.

* Note: remember to choose the right network of the receiving wallet to transfer money from Metamask to the exchange or from the wallet through the wallet. If you choose the wrong network, your coin/token could be lost forever.

Step 4: After entering the Send out wallet address, you can completely choose the fee for trading. The higher the fee, the faster the transaction.

One issue to know and note when using Metamask wallets or DEX wallets is the Gas wei (GWEI) fee, the low gas wei adjustment that has a direct impact on the transfer of pending coins for quite a long time is a very troubling issue. Metamask wallets have a pretty good feature of being able to adjust gas wei fees at will, as well as speed up transactions.

You can choose the level of transfer such as Slow, Average, Fast. In the Transaction Fee section, you click Advanced Options. You can customize the transaction fee.
