Pros and Cons

Like every tool, Metamask comes with its set of strengths and weaknesses:


  1. Ease of use: Metamask’s user-friendly interface makes it a breeze to navigate through the Ethereum blockchain.
  2. Security: It offers robust security features, including local private key storage and manual transaction confirmation.
  3. Wide compatibility: It’s compatible with lots of websites and supports various tokens, enhancing its versatility.
  4. DApp Integration: Seamless DApp integration allows you to interact with decentralized applications directly from your browser.


  1. Target for phishing attacks: Being a popular wallet, Metamask is often a target for phishing attacks. Always ensure you’re on the official website.
  2. Limited to Ethereum-based tokens: While this isn’t necessarily a con for Ethereum users, those wishing to use other blockchains might find this limiting.

Tokens and Adding Blockchains

Metamask primarily supports Ethereum and ERC-20 tokens. This includes a wide range of tokens like Uniswap (UNI), USD Coin (USDC), Dai (DAI), and many others.

However, the Metamask team has been progressively adding support for other blockchains, and custom networks can be manually added. This means you can potentially add any EVM-compatible blockchain to Metamask. Do note that adding custom networks should be done carefully to avoid scams.

Wallet Types and Metamask Classification

Cryptocurrency wallets are broadly categorized as hot or cold wallets.

Hot wallets, like Metamask, are online wallets. They are connected to the internet, allowing easy and quick transactions, making them ideal for regular trading and transactions. However, this constant internet connection could make them more vulnerable to attacks.

On the other hand, cold wallets are offline wallets, not connected to the internet. They are akin to a physical vault and provide optimal security for your digital assets. But the tradeoff is less convenience when making frequent transactions.

Other types of wallets include desktop wallets (installed on a PC or laptop), mobile wallets (on your smartphone), hardware wallets (a physical device storing your private keys offline), and paper wallets (a physical copy or printout of your public and private keys).

Metamask is a hot wallet. It’s connected to the internet, facilitating easy transactions and DApp interaction. It’s also a browser and mobile wallet as it’s available as a browser extension and a mobile app.


In conclusion, Metamask serves as an efficient and secure digital wallet that’s become an essential tool for navigating the Ethereum blockchain. It’s not just a tool for seasoned traders but also a stepping stone for beginners entering the crypto world.
