Coinomi vs. MetaMask | Which Wallet Is the Best?
We will compare two popular multi-currency crypto wallets, Coinomi and MetaMask. Both wallets are non-custodial and multi-functional. However, each has a distinctive set of functions, and knowing them will help you choose the wallet that perfectly meets your requirements. Please read this article to get a better idea of the characteristics of these wallets.
What Is Coinomi?
Coinomi is a versatile multi-currency crypto wallet. It was launched in 2014 by George Kimionis. Currently, the brand is headquartered in the British Virgin Islands. Coinomi supports over 1,770 cryptocurrencies and 168 fiat currencies. If we don't consider NFTs, Coinomi supports the highest number of crypto coins compared to other wallets.
Coinomi app can be installed on smartphones (Android and Apple) or computers. The wallet team did a good job ensuring that Coinomi will be a safe wallet. The wallet supports a segregated witness protocol which enhances the security of transactions. All data doesn't leave the user's device. The access can be regained via seed phrase.
On top of receiving, sending, and storing money, Coinomi can be used to buy and exchange cryptocurrencies. This functionality is realized through integration with Changelly and ShapeShift. Another partner is Binance. Coinomi has quick access to Binance DEX. Also, the wallet allows staking coins and has an inbuilt dapps browser. The latter feature is scarce for crypto wallets.
What Is MetaMask?
MetaMask is a wallet supporting ERC-20 tokens, BNB chain tokens, and custom test blockchains. Moreover, this wallet supports NFTs. Considering it, we can conclude that MetaMask supports thousands of assets. However, it's worth saying that, unfortunately, MetaMask doesn't support Bitcoin.
The wallet was created in 2016. Initially, it was available only as a browser extension, an unusual format for crypto wallets. Later, the dev team released mobile apps, too. MetaMask is an HD wallet. It supports NFTs, in-game tokens and collectibles, staking and swapping tokens. To maintain funds' safety, users should keep the seed phrase and beware of phishing attacks.

Coinomi vs. MetaMask (details)
Platforms
Both wallets can be installed on the mobile phone, but MetaMask doesn't have a full-fledged desktop version, while Coinomi doesn't have a browser extension version. So, these wallets have the same number of formats, and it's up to you whether you prefer a browser extension or a desktop wallet.
Types of transactions
Coinomi and MetaMask share almost the same number of supported transactions, but the former offers one more thing: the ability to exchange coins through the partners' services. It makes Coinomi's functionality more diverse.
Transaction fees
Both wallets don't take transaction fees for crypto operations. That's quite a nice feature!
Supported currencies
If you are not into NFTs, Coinomi seems to be a winner in terms of supported coins. It supports more cryptocurrencies than any other non-custodial wallet. On the other hand, Coinomi is yet to support operations with NFTs, and we don't know if supporting NFTs will be added anytime soon. If you need a wallet that can do operations both with regular cryptos and NFTs, then MetaMask can be a better choice. However, don't forget that MetaMask doesn't support Bitcoin! That can be a serious disadvantage.
Security features
Coinomi and MetaMask are at about the same level security-wise. Both wallets are non-custodial and don't collect user data. This data doesn't leave the user's device. It's up to account owners to beware of scammers and phishing attacks. Access to accounts can be regained via seed phrase.
Payment methods
Payment methods supported on MetaMask and Coinomi seriously differ. Coinomi offers services that are more regular for the major public. It makes this wallet more suitable for people who want a simple service that looks familiar. The fact that Coinomi supports bank card and wire transfers makes it more convenient than MetaMask. However, the latter provides enough decent payment methods as well.
Extra features
Coinomi is more versatile than MetaMask. The latter doesn't provide many extra features on top of staking. For instance, the dapps browser is a unique and outstanding feature to have in the wallet. Access to decentralized exchange and several ways to exchange your coins are great features, too. And staking is also in place, so MetaMask cannot offer any additional features that Coinomi lacks.
Access
Both wallets can be used all across the world, which is beautiful.
