Metamask Wallet- Brings Etherum to your Browser

In the cryptocurrency and blockchain domain, a cryptocurrency wallet is the foremost and the most important gateway to the exposure to the crypto world. There are so many blockchains and so many cryptocurrencies. The most popular and the leader of crypto world are BTC, ETH, etc.

The Etherum chain was evolved in 2013 which brought the concept of smart contract and decentralized applications. As on date, there are so many decentralized applications and so many ERC20 tokens. So the tokenomics in Etherum ecosystem equally needs better wallet management which, will not just cater management of ETH/ERC20 tokens but also the interactions with dapps, but also the built-in exchanges to allow users to buy ETH. If all these facilities can be brought together to one place and can be offered in a simple way with intuitive user interface then it can bring mass adoption and people will feel easy to get into the crypto world. Metamask wallet aims to offer such a solution to the users of Etherum ecosystem.

Supported coins/tokens

It supports ETH coin and all ERC20 tokens. So Metamask is exclusively for Etherum ecosystem.

Built-in Exchanges

Metamask has integrated with Coinbase(for USA customer only) and Shapeshift. In other words, it has built-in exchanges which enable users to buy ETH within its user-interface.

Getting started with Metamask

Go to https://metamask.io/. Then get the extension and for that select the suitable browser of your choice. I have chosen the Opera browser.

It will be redirected to Opera addons page where you need to click on "Add to Opera". It will then start installing.

Once installed you can see the tiny Metamask addon in the browser. Then click on that addon.

Accept the privacy notice.

Accept terms of use.

Set the password for your wallet. Then click on "Create".

Then you can see the 12 words displayed right in front of you. This is the most important part. You must keep these 12 words in a safe place, preferably write it down in a paper and save it offline. This is essential to restore/recover your wallet in future.

Then click on "I've copied it somewhere safe".

Now your account is created.

In the Main Network link if you click, then you can see there is "Main Etherum Network" and many other "Test Network". The Etherum Main Network is by default selected, as for a normal user Main Etehrum Network is of use. However, if you are a developer and developing dapps in Etherum network then you can make use of the Test network for testing purposes.

You can also create multiple accounts (ETH addresses with the same wallet, means with same private keys). You can import account too but in that case, the private keys will be different.

You can also edit the name of the account as per your choice and can save it.

If you click on the account there are various options showing such as "View account on Etherscan, Show QR code, Copy Address to clipboard, Export private key, etc." So it is easy for a user to easily copy the address, scan the QR code and also can check & track the transaction on Etherscan. Metamask has simplified the things for a user.

A user can also add ERC20 token in Metamask wallet. For that click on "Add Token". Then input the "Token Contract Address", "Token Symbol", "Decimals". Then click on "Add".

A user can buy ETH directly from the user interface of Metamask. For that click on "Buy", then you can see two options "Coinbase" & "Shapeshift". However, Coinbase is available for USA customers only. You can choose either of the two and can proceed to the exchange to buy ETH.

In order to send ETH or any other ERC20 tokens, the user has to click on "Send". Then input the "Recipient Address", "Amount". Then click on "Next".

Comparison of Metamask with MEW

Review & rating

I must say that the goal to make the access of blockchain easy for a common user and to interact with various dapps in Etherum ecosystem along with managing so many tokens have become really easy with Metamask. So it really a pro considering the mass adoption. On the downside, security and privacy are somewhat dependent upon the browser where it is installed as an addon. So users must take additional precaution in this context.

Overall I would like to give a 4.25-star rating out of 5 stars to Metamask wallet.

Conclusion

The journey of Metamask wallet has really been better and the user interface has really improved in time. The goal to offer a simple and user-friendly interface along with decentralized experience and other parallel objectives where the crypto wallet is not just limited to managing tokens but also interaction with the dapps in the network through the browser, has been achieved with Metamask wallet. I can see it as a potential to lower the barrier of entry & opening an easy window for mass adoption.
