Greetings friends, today we are going to dive in detail into the design of one of the hot wallets – the interface, Metamask. This article will be suitable for both beginners and experienced cryptans who have been around for a while. We will break down the pros and cons of Metamask, as well as tell you some tricks in its use.
What is Metamask?
Metamask is a programmable cryptocurrency wallet developed by ConsenSys Software Inc. focusing on Ethereum blockchain solutions. This wallet was originally introduced as a browser extension for Chrome and Firefox, becoming popular among Ethereum blockchain users due to its simple interface and ease of synchronisation with decentralised exchanges that support Ethereum.
Early on, Metamask faced the problem of counterfeit counterparts in extension shops, leading to the release of iOS and Android mobile apps in September 2020. It is important to note that installing an extension or mobile app is not mandatory, but is recommended for increased security.
Metamask ensures ease of use and provides a wide range of functionality, including the ability to deposit, withdraw and make payments in a few clicks. Interaction with decentralised applications and Ethereum exchanges is done using a JavaScript module (Web3js or Ethers).
One of the characteristic features of Metamask is an integrated Ethereum token exchange service that connects multiple decentralised exchanges to find the best exchange rate.
The main wallet features include sending and receiving ETH and tokens, as well as the ability to store and withdraw funds with the payment of Ethereum’s standard gas fee. There is an additional swap fee of 0.875% of the transaction amount. Metamask also supports interaction with dApp applications and allows participation in buying and selling NFTs.
An overview of the Metamask extension features:
Storage and Transfers:
Metamask provides a convenient algorithm for storing and transferring funds. Users can easily deposit Ethereum coins and stablecoins of this blockchain. No storage fees and with the ability to make transfers through any Ethereum networks. The only fee is for gas usage.
Buying and selling NFT:
You can easily buy and sell non-fungible tokens (NFTs) on decentralised exchanges (DEX) in Metamask. The user’s collection is displayed on the app’s home screen, and tokens can be placed on the respective exchanges, participate in auctions, and receive funds from the sale of NFTs.
dApp applications:
The Metamask extension provides the ability to conduct transactions in various decentralised applications (dApps) on the Ethereum blockchain. It doesn’t matter to the user which platform they are interacting with the application on, as Metamask supports multiple of them.
Swaps:
The recently introduced swaps feature allows users to exchange their tokens for other tokens. The system automatically monitors DEX exchanges and selects the best exchange offer, ensuring favourable conditions and minimal network fees.
Token Purchase:
Users can purchase a variety of Ethereum tokens of different standards. A simple purchase process where the system selects the best quotes based on region and available providers. The ability to purchase stablecoins and native tokens on various networks (Ethereum, Polygon, Binance Smart Chain, etc.) using a card, bank account or mobile payment.
These features make Metamask a powerful tool for managing cryptocurrency assets, participating in the growing world of decentralised finance and interacting with a variety of applications on the Ethereum blockchain.
👍 Benefits of Metamask Wallet:
- Ease of use: Metamask is known for its simple and intuitive interface, making it one of the easiest wallets to use.
- Availability across platforms: Users can choose between a browser extension and a mobile app, ensuring ease of use in a variety of scenarios.
- Multi-asset support: Metamask supports not only Ethereum (ETH) but also all tokens based on it, making it versatile for different cryptocurrency assets.
- Minimal fees: The wallet only charges a standard gas fee as well as an additional swap fee, providing transparency and predictability of costs.
- Support for smart contracts and NFTs: Metamask provides the ability to interact with smart contracts, including buying and selling NFTs, making it suitable for participation in various decentralised applications and activities.
- Integration with dApp: The wallet easily integrates with decentralised applications (dApps) on the Ethereum platform, providing users with a user-friendly experience.
- High security: Metamask provides a high level of security, which is especially important in the context of storing cryptocurrency and interacting with decentralised financial services.
👎 Disadvantages of Metamask wallet:
- Transaction time: Transactions can sometimes take a long time to process, which can lead to higher fees during peak activity.
- High cost of gas on the Ethereum network: The cost of gas is on average higher on the Ethereum network, and users may need to explore the features of the EIP-1559 protocol to optimise costs.
- Risk in device hacking: Since private keys are stored on the user’s device, if the device is hacked, an attacker will have access to them, emphasising the importance of securing the device itself.
Yes, Metamask is a free wallet, available to install via a browser extension or downloading the mobile app. The wallet itself does not charge transaction fees. Instead, the user pays a standard fee for gas on the Ethereum blockchain.
In the context of Ethereum, the concept of “gas” reflects the amount of computing power expended to execute a particular transaction. Complex transactions require more gas, which increases the fee accordingly. In addition, the cost of gas depends on the current workload of the Ethereum network. On average, gas fees are higher on the Ethereum network compared to some other blockchains.
With the EIP-1559 protocol, the user has the ability to adjust the amount of gas, which affects the speed of transaction execution. This allows users more flexibility in managing costs and choosing the optimal level of gas based on their needs.
Metamask provides a high level of security using three layers of protection: password, private keys and a passphrase of at least 12 words. These measures provide additional layers of protection to prevent unauthorised access and ensure cryptocurrency assets are stored safely.
- Password: The user sets a password to access their wallet. Metamask recommends not storing the password digitally and writing it down on paper to increase security.
- Private keys: A private key, which is a randomly generated sequence of digits, is used to identify the user and confirm transactions. This key is stored on the user’s device (browser or mobile app).
- Passphrase: The user receives a passphrase of at least 12 words when setting up the wallet. This phrase is necessary to restore access to the wallet in case of loss of the password or private keys.
In case of losing the password or private keys, the user can use the passphrase to regain access. Nevertheless, it is important to keep the passphrase in a safe place, as without it recovery becomes impossible.
Storing private keys on the user’s device, as in the case of Metamask, provides an additional layer of security. At the same time, it is important to monitor the overall security of the user’s device by installing anti-virus software and avoiding connections to unreliable Wi-Fi networks.
Security issues in Metamask wallet:
There have been no hacking incidents during the existence of Metamask and the system continues to maintain a high level of security. Nevertheless, incidents are encountered when funds leave the wallet. These incidents, however, are not related to a breach of Metamask’s security. More often than not, attackers hack into the user’s PC, gaining access to browser data and eventually private keys.
The secret to success is not to store the password and passphrase on digital devices. Metamask recommends writing this data down on paper and keeping it out of reach. Users can also increase security by using hardware wallets such as Trezor or Ledger.

Auto-token detection
To improve security in Metamask, it is recommended that you disable the automatic token detection and NFT (non-replaceable tokens) feature. This can help in preventing potential risks from fraudsters and malicious actors. To perform this action, follow the instructions below:
- Open Metamask: Launch the Metamask app on your browser or mobile device.
- Go to settings: Inside Metamask, find the settings or preferences section. This is usually represented by a gear icon or profile icon.
- Find security settings: Go to the security or settings section of your wallet.
- Disable token and NFT auto-detection: Look for the option related to token and NFT auto-detection. Select “Disable” or follow a similar action according to your interface.
- Confirm your changes: You may need to confirm your selection by following the on-screen instructions.
By disabling token autodetection and NFT, you will maintain control over which assets show up in your wallet and reduce the likelihood of falling for fraudulent schemes. Remember the importance of following basic security principles and regularly updating your software to minimise risks.
