MetaMask is the best-known non-custodial crypto wallet for Ethereum and EVM-compatible networks. For millions of people it is the first step into DeFi, NFTs and decentralized apps: the browser extension, the orange fox and the “Connect wallet” button have become a de facto Web3 standard. Yet MetaMask has changed a lot over the last two years. It is now a multichain wallet with Solana, Bitcoin and TRON, built-in swaps, staking, smart accounts and even perpetual futures.
This MetaMask wallet review is for people choosing their first wallet for Ethereum and tokens, and for experienced users who want to understand what has changed in the app and what they actually pay for. It is not an advertisement: we look at the real strengths and weaknesses.
You will learn how MetaMask works, which networks it supports, where the fees come from, how to install and secure it properly, who it suits and who should pick an alternative instead.

What is MetaMask
MetaMask is a non-custodial (self-custody) wallet. Your private keys are generated and stored on your own device, not on the company’s servers. The developer cannot freeze your funds, but it also cannot restore access if you lose your recovery phrase. All responsibility for the keys sits with you, which is both the main strength and the main risk of this model.
The wallet comes in two forms: a browser extension (Chrome, Firefox, Brave, Edge, Opera) and a mobile app for iOS and Android. The extension has always been the flagship product: it is how users connect to decentralized exchanges, lending protocols, NFT marketplaces and other dApps. The mobile app adds a built-in Web3 browser and is handy for everyday transactions.
Technically, MetaMask is an interface to the blockchain. Your coins and tokens do not “live” inside the app: balances are recorded on-chain, and the wallet simply stores keys and signs transactions. If you are new to the topic, it helps to read first what a crypto wallet is and how hot and cold wallets differ.
History and developer
MetaMask was created by Consensys, the company founded by Ethereum co-founder Joseph Lubin. The first version of the browser extension appeared in 2016, built by developers Aaron Davis and Dan Finlay. The mobile app followed in 2020, once it became clear that Web3 was not going to stay on the desktop.
For years MetaMask was an “Ethereum and EVM only” wallet. In 2023 it launched Snaps, a platform that lets third-party developers extend the wallet. It then moved to multichain accounts: native Solana support arrived in May 2025, Bitcoin in December 2025 and TRON in January 2026. A single Secret Recovery Phrase now derives addresses for several ecosystems at once.
MetaMask’s source code is published on GitHub and anyone can inspect it. There is a nuance, though: the wallet is distributed under Consensys’s own license rather than a standard OSI-approved open-source license. For most users this does not matter much, but open-source purists should be aware of it.
Which networks MetaMask supports
MetaMask’s core specialty is EVM-compatible networks, meaning blockchains that run the Ethereum Virtual Machine. They all share the same address format starting with 0x. That is why one EVM address in MetaMask works on Ethereum, Arbitrum, Base, BNB Smart Chain and others, while balances on each network are tracked separately.
| Ecosystem | Example networks | Address format | Coin used for fees |
|---|---|---|---|
| Ethereum and EVM L1s | Ethereum, BNB Smart Chain, Avalanche C-Chain | 0x… | ETH, BNB, AVAX |
| Ethereum Layer 2 | Arbitrum, Optimism, Base, Linea | 0x… | ETH on that network |
| Polygon | Polygon PoS | 0x… | POL |
| Solana | Solana mainnet | Base58 address | SOL |
| Bitcoin | Bitcoin mainnet | bc1… | BTC |
| TRON | TRON mainnet | T… | TRX or Bandwidth/Energy resources |
Beyond the built-in list, you can add any EVM network manually via its RPC URL. Be careful here: only take network parameters from the project’s official documentation or trusted aggregators such as Chainlist, otherwise an attacker could feed you a malicious RPC. Layer 2 networks appear in MetaMask as separate networks, even though they rely on Ethereum for security.
Non-EVM networks that MetaMask does not support natively can sometimes be added through Snaps. Keep in mind that every Snap is extra code you trust with part of your wallet’s functionality, so install only those listed in the official directory.
Key wallet features
Sending, receiving and tracking tokens
The basics — transferring coins and tokens, viewing balances and history — work on every supported network. MetaMask auto-detects many popular tokens, and rarer ones can be added manually by contract address. Always verify the contract address on the project’s official website or a block explorer: fake tokens with the same name are common.
Swaps and bridges
The built-in Swap feature pulls quotes from several aggregators and DEXs and shows what it considers the best option. Bridge moves assets between networks, including between EVM chains, Solana and Bitcoin. It is convenient because you do not need a separate service, but that convenience comes with a service fee (covered below).
Staking
MetaMask lets you stake ETH, either through a pool (suitable for small amounts) or by running your own validator for larger holders. Staking yields are not fixed and depend on network conditions, and a service fee is deducted from rewards. On TRON, the mobile app supports staking TRX to obtain Bandwidth and Energy resources.
Smart Accounts
Since the Ethereum upgrade that activated EIP-7702, a regular MetaMask account can be upgraded to a smart account without changing its address. This enables batched transactions (for example, approve and swap in one step), gas sponsorship and fine-grained permissions. You can switch the feature on or off for each network.
Additional products
The MetaMask ecosystem now includes the MetaMask Card for spending crypto, its own mUSD stablecoin, perpetual futures trading powered by Hyperliquid and prediction markets. Availability depends on your country: some of these are closed to residents of the US, the UK and several other jurisdictions. Remember that leveraged futures are high-risk products where you can lose your entire margin.
Fees: what you pay for
The MetaMask wallet itself is free: you can download it, create an address, and send or receive coins with no subscription. Each transaction, however, involves one or two types of cost.
- Network fee (gas). It goes to the blockchain’s validators, not to MetaMask. The amount depends on network congestion and the complexity of the operation. Our article on gas in Ethereum explains how it works and how to save on it.
- MetaMask service fee. Charged on swaps, bridges, staking, perpetuals and some other features. For swaps it is a percentage of the amount already included in the quote you see. The exact rate is shown in the interface and terms of service and may change.
- Provider fees. When you buy crypto with fiat through built-in partners, the payment provider charges its own fee.
The practical takeaway: the built-in swap is convenient but not always the cheapest option. For larger amounts it is worth comparing the final result against using a DEX directly or an exchanger where the rate and fee are visible up front.
MetaMask security
MetaMask stores keys locally in encrypted form, protected by a password. Access is recovered using a Secret Recovery Phrase of 12 words. Anyone who obtains this phrase gets full control of every address on every network. We cover storage rules in detail in seed phrase: what it is and how to store it safely.
The wallet includes built-in security alerts: before you sign, MetaMask simulates the transaction and warns you about suspicious requests, known phishing sites and attempts to obtain unlimited token approvals. This noticeably reduces risk but does not rеplace your own attention: alerts cannot catch every new scheme.
The strongest option for large amounts is to connect a hardware wallet. MetaMask works with Ledger, Trezor and several other devices: you keep the familiar interface while the keys never leave the secure chip. Our comparison of the two most popular devices is in Ledger vs Trezor.
The main threats to MetaMask users are not hacks of the wallet itself but social engineering: fake websites and extensions, fake “support” on social media, signing malicious approvals and permits, and address poisoning attacks, where a look-alike address is planted in your transaction history. Genuine MetaMask support will never ask for your recovery phrase.
How to install and set up MetaMask
Setup takes a few minutes, but this is exactly where most fatal mistakes happen. Follow the steps in order.
- Download the wallet only from the official source. Follow the link from metamask.io to the Chrome Web Store, App Store or Google Play. Search results often contain sponsored fakes.
- Create a new wallet and set a strong password. The password protects the wallet on this device but does not rеplace the recovery phrase.
- Write down the 12-word phrase on paper. Do not photograph it or keep it in notes, cloud storage or messengers. Double-check the word order.
- Complete the phrase check. The wallet will ask you to pick several words to confirm that you actually saved them.
- Configure networks. Enable the networks you need, and add extra EVM networks only from official sources.
- Fund the wallet with the network’s native coin. Without ETH on Ethereum or SOL on Solana you cannot pay the fee, even to move tokens.
- Send a test transaction. Transfer a small amount and confirm it arrives before moving your main funds.
- For large amounts, connect a hardware wallet. It appears as a separate account in MetaMask, and every signature is confirmed on the device.
Once the wallet is ready, you need to fund it. If you hold stablecoins or other crypto, you can exchange them for ETH on RubyCash without registration and enter your MetaMask address as the receiving address — just make sure you pick the right network.

Pros and cons
MetaMask strengths:
- Maximum dApp compatibility: almost every Ethereum service supports MetaMask.
- Broad EVM network support plus the ability to add custom networks via RPC.
- Multichain accounts: Solana, Bitcoin and TRON from the same recovery phrase.
- Integration with Ledger and Trezor hardware wallets.
- Built-in security alerts and transaction simulation.
- A large community, a detailed knowledge base and a long track record.
Weaknesses:
- Service fees on swaps and bridges are higher than using a DEX directly.
- The interface is packed with features and can confuse beginners.
- Its popularity makes MetaMask the top target for phishing and fake extensions.
- The license is not a standard open-source one.
- Some products (the card, perpetuals, yield accounts) are not available in every country.
- It is a hot wallet: keys live on an internet-connected device.
Who MetaMask is for
MetaMask is the logical choice if you actively use DeFi and apps in the Ethereum ecosystem: DEXs, lending, NFTs, Layer 2 networks. It is also a good fit if you want one wallet for EVM networks plus basic BTC, SOL and TRX operations, and for hardware wallet owners who need a convenient interface to connect to dApps.
It is a weaker fit if you are a beginner who simply wants to hold bitcoin long term: a hardware device or a dedicated bitcoin wallet is simpler and safer for that. If most of your activity is on Solana, TON or another ecosystem, that network’s native wallets are usually more convenient. And MetaMask is not the best place to keep a large balance without a hardware wallet attached.
MetaMask vs alternatives
Here is a short comparison of MetaMask with other popular wallets. Features change over time, so check the official websites before deciding.
| Wallet | Type | Main strength | Core ecosystem |

FAQ
Yes, you can download MetaMask and use it to store, send and receive crypto for free. You pay the blockchain’s network fee on every transaction. An additional MetaMask service fee applies only to certain features, such as swaps, bridges and staking.
For everyday amounts MetaMask is reasonably safe if you follow the basics: use the official version, a strong password and keep the recovery phrase only on paper. For large amounts, connect a hardware wallet so the keys are never stored on your computer or phone.
Yes. Since December 2025 MetaMask supports native Bitcoin: each multichain account gets its own BTC address. You can send, receive and swap BTC. Previously MetaMask only supported wrapped bitcoin on Ethereum networks.
Yes. Solana was added in May 2025 and TRON in January 2026. Addresses for these networks are generated automatically from the same Secret Recovery Phrase as your EVM address.
If you can still open the wallet with your password, go to the security settings right away and back up the phrase again. If you have lost both access and the phrase, the funds cannot be recovered, because MetaMask does not hold your keys. That is why backing up the phrase is the most important step when creating a wallet.
Most often the wrong account or network is selected, or the token was not detected automatically. Check your address in the block explorer of the right network and, if needed, add the token manually using its official contract address.
No. MetaMask does not control your keys and cannot reverse a blockchain transaction. Anyone posing as support who promises to recover funds or asks for your recovery phrase is a scammer.
Yes, MetaMask supports Ledger, Trezor and several other hardware wallets. You see the device account in the MetaMask interface, but every transaction is confirmed physically on the device and the keys stay inside it.
Conclusion
MetaMask remains the reference wallet for Ethereum and EVM networks: it offers the best compatibility with decentralized applications, hardware wallet support and mature security tooling. The move to multichain accounts with Solana, Bitcoin and TRON has made it more versatile, and smart accounts have made it more convenient.
It is still important to keep the trade-offs in mind. Built-in swaps and bridges are convenient, but the convenience carries a service fee. The interface has become more complex, and popularity attracts scammers. It is a hot wallet, so for large amounts it is best paired with a hardware device.
If you are willing to follow the basic security rules — keep your phrase offline, check websites and approvals, send test transactions — MetaMask is a reliable gateway into Web3.
