MetaMask is a well-known and trusted non-custodial cryptocurrency wallet that has millions of active users around the world. But is it still safe to use in 2025? The short answer is: yes.

MetaMask is a safe way to store your Ethereum, NFTs, and other tokens, but how you use it is what truly determines your security. Many users lose their crypto to phishing scams, sketchy decentralized apps (dApps), and other frauds that could easily be avoided. Those who pay attention to MetaMask security and remain vigilant against potential threats have a vastly different experience when handling their crypto.

Read on to learn how to avoid common mistakes when using MetaMask and discover all the essential information for using it securely.

Is MetaMask Safe?

The crypto community says that MetaMask is safe to use in 2025, thanks to its strong security features like encryption, regular updates, and seed phrase recovery. Additionally, MetaMask doesn’t keep any private data on its servers, which further helps prevent your crypto from falling into the wrong hands.

Being open source is another reason why MetaMask is a safe choice for a cryptocurrency wallet. Because of this transparency, anyone, even security experts, can look at its code, find possible bugs, and report them before they cause real hazards.

What is MetaMask?

MetaMask is a self-custodial cryptocurrency wallet that Consensys developed. You can use its app or browser extension to sell, buy, bridge, and manage your crypto overall.

MetaMask can be integrated with many EVM-compatible blockchains, but Ethereum users will find this wallet particularly useful. This is because MetaMask connects them to the whole Ethereum ecosystem. In particular, it lets you use thousands of dApps, buy and sell NFTs, and connect to DeFi platforms without having to switch wallets or make multiple accounts.

MetaMask is a free and safe cryptocurrency wallet that you can use on a number of browsers and mobile operating systems, such as iOS and Android. The only time MetaMask charges fees is when you use its built-in providers to buy or sell crypto, where they take a 1% transaction fee.

How Does MetaMask Work?

Now that we know what MetaMask is and whether or not it’s safe, it’s valuable to understand how this self-custodial wallet operates if you intend to use it.

MetaMask works as a browser extension or mobile app. It stores your crypto keys on your device, not on any company’s servers. When you set it up, MetaMask gives you a 12-word secret backup phrase that can recover your entire wallet. And since you control the keys, no one else can access your funds but you.

The MetaMask app links your device to the blockchain so you can use a cryptocurrency app. First, the app asks for permission to access your wallet. Next, it shows you transaction details like how much crypto you’re sending and where it’s going. After reviewing every detail displayed, you can then confirm the transaction with a password.

With MetaMask, you are also allowed to use Ethereum and other blockchains without having to switch between wallets. This means you can easily access DeFi platforms, buy NFTs, and use thousands of other crypto apps from one platform.

MetaMask Security Features

Based on cybersecurity statistics showing rising threats within the crypto world, MetaMask has been busy building several strong security features to protect your assets.

For example, when you use MetaMask, your private keys are kept on your device instead of on company servers, so hackers can’t get them from a central database. The wallet also encrypts all data and communications from end to end so that no one can see the details of your transactions.

Also, MetaMask needs your confirmation for every transaction and interaction with a dApp. This way, even if someone gets into your device, they can’t do anything without your permission and confirmation. And finally, the people who worked on MetaMask added Blockaid protection, which checks transactions and websites for scams before you use them.

However, even with MetaMask’s strong security measures in place, keeping your assets safe ultimately remains your responsibility. The strongest wallet security measures mean nothing if you fall for phishing scams, share your seed phrase, or ignore other warning signs from suspicious dApps.

What Are the Benefits of MetaMask?

MetaMask has a lot of great features that make it easier to use Web3 apps and manage your crypto. Here’s a list of our favorite MetaMask benefits:

• Easy to use. The setup and interface are simple enough for beginners, but still have everything that advanced users need.
• Your keys, your crypto. You own your private keys completely, so no one can lock you out or take your money.
• Built into your browser. MetaMask doesn’t require you to do any extra downloads. Just add the extension and start using crypto apps right away.
• Works with many blockchains. With MetaMask, you don’t need different wallets to switch between Ethereum, Polygon, and other networks.
• Handles all your tokens. With automatic detection, you can keep all of your regular crypto, NFTs, and other new tokens in one place, conveniently.
• Keeps things safe. Your keys stay on your device with strong encryption and are never sent to the company’s servers.
• Opens up Web3. MetaMask allows you to instantly connect to DeFi apps, NFT marketplaces, games, and thousands of other crypto services.
• Customizable transaction fees. If you want your crypto transactions to go faster, pay more. If you don’t, pay less.
• Gets better over time. Regular updates of the MetaMask platform add new features and help keep the wallet updated with what’s new in the crypto world.

What Are the Risks of Using MetaMask?

So, we can confirm that MetaMask is legit. However, despite the robust security measures in place, users of this cryptocurrency wallet could still lose their money in a number of ways.

• Phishing scams. Fake websites may imitate the legitimate MetaMask website in hopes that you will enter your seed phrase on their website, even though you thought you were logging into the real site.
• Malicious apps. Some dApps can request unlimited access to your tokens and empty your wallet once you approve them.
• Buggy smart contracts. Broken code in contracts can lock up or steal your money with no way of getting it back.
• Software problems. Hackers can try to exploit unknown bugs or vulnerabilities in MetaMask before their IT team acknowledges and fixes them.
• Your own mistakes. Losing your seed phrase, sending it to the wrong address, or approving sketchy transactions can quickly make your money disappear forever.
• Browser issues. If your browser gets hacked or you install bad extensions, malicious hackers who control these threats can steal your wallet information.

MetaMask keeps adding better protection and scam alerts, but most crypto losses happen because people aren’t careful enough with their wallets.

What Are the Disadvantages of MetaMask?

Like said already, MetaMask encompasses many safety features to keep your crypto as safe as possible. Nonetheless, there are a few issues that users need to consider before making MetaMask their main cryptocurrency wallet. Here are some of them:

First things first, MetaMask is a “hot wallet,” which means it’s always online. Because of this, it’s more likely to be hacked than other offline ways to store your cryptocurrency. Suppose you’re using MetaMask as a browser extension. In that case, you must ensure the wallet is compatible with your browser, as updates or extensions that conflict with it can stop it from working correctly.

MetaMask also doesn’t have a dedicated customer service team, which is a significant downside in most unfortunate cases. If you lose access or have problems with your app, extension, or account, you can’t call a help desk for help. The worst part is that if you lose your seed phrase or private keys, you will never be able to get back your money or recover it in any way, shape, or form.

How Can I Secure My MetaMask Wallet?

Here are a few things you can do to protect your MetaMask wallet from threats and possible losses:

• Use a strong password. Make a strong password that you only use for this wallet and nowhere else. By doing this, hackers won’t be able to get into your wallet, even if they somehow find out your other account passwords.
• Enable auto-lock. MetaMask can be set to lock itself after a few minutes of inactivity. By enabling this feature, you will ensure that the auto-lock will keep your wallet safe if someone gets into your device.
• Avoid phishing scams. Always type metamask.io directly into your browser instead of clicking links. Fake sites that look identical to the real one can steal your seed phrase and sensitive information, even when you think you’re on the legitimate site.
• Keep MetaMask updated. Install MetaMask updates as soon as they’re available, as they often fix security vulnerabilities. It’s well known that outdated software is easier for attackers to exploit.
• Use only trusted websites. Research dApps before connecting to them and stick to well-known platforms with good reputations. Malicious sites can drain your wallet through hidden permissions.
• Secure your connection. Always use a VPN when accessing MetaMask on public Wi-Fi to encrypt your internet traffic. This will prevent others from intercepting your online activities and wallet data.
• Consider hardware wallets. Connect a Ledger or Trezor to MetaMask for extra crypto security since they store your keys offline. This will come in handy if you ever experience software-based attacks.
• Protect your seed phrase. Make note of your 12-word recovery phrase and keep it in different safe places offline. Do not ever save a screenshot in a digital location where hackers could potentially access it.
• Know how recovery works. If you lose access to your MetaMask account, you can restore your entire wallet using just your seed phrase. For this very reason, protecting those 12 words is absolutely critical.

If you follow these tips, you’ll be much less likely to lose your crypto. But remember that, after all, you’re the one in charge of keeping your wallet safe.

MetaMask Compatibility and Token Support

MetaMask works with Ethereum and tons of other blockchains that use similar technology. You can easily connect to networks like Binance Smart Chain, Polygon, and Avalanche by adding their network details in settings. This lets you use one wallet for crypto across different blockchains instead of juggling multiple apps.

The MetaMask wallet automatically finds most tokens on these networks, especially popular ones like USDC. If you have newer or less common tokens, you can add them manually by pasting them into their contract address. MetaMask will then show your balance and let you send those tokens just like any others.

You can also connect hardware wallets like Ledger or Trezor to MetaMask for extra security. This will give you the easy interface of MetaMask while keeping your private keys safely stored offline on the hardware device. This will ensure you have a great setup that prioritizes convenience without sacrificing security.

What Are the Best MetaMask Alternatives?

Many people like using MetaMask as their crypto wallet, but it’s completely normal to look at other options when choosing one for yourself. Aside from MetaMask, there are many other wallets that offer different features and blockchain support, and here are some of them:

• Coinbase Wallet supports multiple blockchains, including Bitcoin, and has a built-in dApp browser. It’s user-friendly for beginners but connects to Coinbase’s ecosystem.
• Trust Wallet covers more blockchains than MetaMask, including Solana and Cosmos networks. Also, it offers staking rewards and has strong mobile functionality.
• Phantom focuses specifically on Solana and its ecosystem. It’s fast, intuitive, and perfect for Solana DeFi and NFTs, but limited to a blockchain.
• Exodus provides a great desktop experience with built-in exchange features. Importantly, it supports many cryptocurrencies but has fewer Web3 features than browser-based wallets.
• Brave Wallet is built into the Brave browser and supports Ethereum and Solana. It offers enhanced privacy features and doesn’t require separate downloads.

These alternatives have the same risks as MetaMask, like phishing attacks, user errors, and malicious apps. However, they do have different blockchain coverage, security, and user interfaces. So, do some good research about each and choose your crypto wallet based on which blockchains you use most and your preferred device setup.
