A wallet is a tool, not a bank.
01 — THE BASICS
What is the MetaMask
Chrome wallet?
Think of it as your personal keyring for the decentralized web.
MetaMask is a self-custody cryptocurrency wallet that you can add to Google Chrome as a browser extension. It helps you manage supported digital assets and connect to decentralized applications—often called dapps—on networks such as Ethereum. There is also a MetaMask mobile app, but this guide focuses on the Chrome browser experience.
Unlike an account at a traditional bank or a profile on a crypto exchange, a self-custody wallet does not hold your funds for you. Your assets are recorded on a blockchain; MetaMask gives you an interface for viewing them and a way to authorize actions with your wallet’s keys. You are responsible for keeping those keys and your recovery phrase safe.
That distinction is important: MetaMask is software, not a bank, investment adviser, or customer-support desk that can reverse a blockchain transaction. A wallet can make web3 easier to access, but it cannot make every token, website, or transaction safe. Take time to understand each approval before signing.

02 — GETTING SET UP
Install with care.
Start with the source.
A few deliberate steps now help protect your wallet later.
Add the extension
On the official Chrome Web Store listing, review the publisher and choose the option to add the extension to Chrome. Confirm the browser prompt. Once installed, pin the MetaMask icon from Chrome’s Extensions menu for convenient access.
Create or restore
Open the extension and follow its setup screens to create a wallet or restore one you already control. Choose a strong, unique password for this browser profile. A password protects local access; it is not a replacement for your recovery phrase.
Back up offline
Carefully write down your Secret Recovery Phrase and store it somewhere private and secure, offline. Never take a screenshot, paste it into a website, send it in a message, or share it with support. Anyone requesting it is not helping you.
Already have a wallet? Restore it only in the genuine extension, and only on a device you trust. Never enter your recovery phrase into a page reached through an ad, direct message, or unfamiliar link.
Official download03 — DAY TO DAY
Using your wallet,
one decision at a time.
The important moments happen before you click confirm.
Read the security checklistCheck the network
Networks are separate blockchains or environments. Before sending funds or connecting to a dapp, confirm that the selected network is the one the service expects. An address can look familiar across networks while an asset remains on the wrong one.
Connect selectively
Connecting a wallet usually lets a site see your public address; it does not, by itself, give that site your recovery phrase. Still, only connect to a site you meant to visit. Review permissions and use wallet settings or trusted tools to disconnect old connections when appropriate.
Read every request
A transaction can transfer an asset, interact with a contract, or approve a token allowance. Check the destination, network, amount, and any requested permissions. If the purpose or cost is unclear, reject it and investigate before trying again.
Send a small test first
Crypto transfers are generally irreversible. Verify the recipient address and network character by character, and consider a small test transfer before sending a larger amount. Be aware that network fees may apply to both transactions.
04 — KEEP YOURSELF SAFE
Security is a habit,
not a setting.
The wallet can prompt you. You are the final checkpoint.
MOST IMPORTANT
Guard your recovery phrase
Your Secret Recovery Phrase can restore wallet access. Never disclose it—not to a person claiming to be MetaMask support, not to a website, and not to an app promising to fix a problem. MetaMask support will never need it to troubleshoot.
VERIFY
Watch for impersonators
Fake support accounts, cloned sites, malicious extensions, and urgent “wallet compromised” messages are common phishing tactics. Navigate directly to official resources; do not trust a link just because it looks familiar.
PROTECT
Secure your device
Keep Chrome and your operating system updated, use a device lock, and install only extensions you trust. A browser password does not protect against malware or someone who gains access to an unlocked device.
REVIEW
Pause before signing
Read transaction details even when a familiar dapp asks for approval. A signature is not always a simple login: some signatures authorize meaningful actions. If a prompt surprises you, cancel it and verify independently.
05 — NETWORKS & FEES
Understand the route
before you move.
Wallet support, tokens, and fees depend on the network and the action.
MetaMask supports Ethereum and a range of other compatible networks; availability and features can change. Each network has its own assets, applications, and transaction costs. A token displayed on one network is not automatically available on another, even if the name or ticker matches.
Many networks charge a fee—often called gas—to process transactions. Fees can vary with network activity and the complexity of an action. Review the fee estimate shown in the wallet before confirming, and make sure you have the relevant network’s native asset available when needed to pay it. Do not rely on a fixed fee estimate from an old article or message.
Adding a custom network or token requires extra care. Use details from a project’s verified official documentation, and compare them before saving. Scam tokens can copy the name and icon of legitimate assets. A familiar logo is not proof that a token is authentic, valuable, or safe to interact with.
06 — WHEN SOMETHING FEELS OFF
Pause. Verify.
Then troubleshoot.
A calm first response can prevent a small issue from becoming a costly one.
The extension is missing
Open Chrome’s Extensions menu and check whether MetaMask is installed and enabled. Verify you are using the browser profile where you installed it. Reinstall only by navigating directly to the official site and linked store listing.
A transaction is pending
Check the correct network’s block explorer using the transaction hash, and consult official help for that network and wallet. Avoid strangers offering to “speed up” a transaction in exchange for your recovery phrase or a payment sent to them.
A website or prompt looks wrong
Disconnect from the site, close the tab, and do not approve anything else. Visit official MetaMask support by typing its address yourself. If you believe a secret phrase was exposed, use official guidance from a clean, trusted device as soon as possible; never share the phrase with a helper.
07 — QUICK ANSWERS
Is MetaMask a Chrome wallet or an exchange?
It is a self-custody wallet extension for Chrome, with a mobile app as well. It is not a bank account, and using it is different from keeping assets on a centralized exchange.
Can MetaMask recover my Secret Recovery Phrase?
No. In self-custody, you are responsible for your recovery phrase. MetaMask support cannot retrieve it for you. Keep your backup private and offline.
Is installing the extension free?
Installing the wallet extension is free. Some optional services and blockchain transactions may involve fees. Review current wallet screens and official documentation for details before taking action.
Can I undo a crypto transaction?
Most confirmed blockchain transactions cannot be reversed by MetaMask or a recipient. Verify the address, amount, and network before you confirm.
Where should I get help?
Start from the support link on the official MetaMask website. Real support will not ask you to reveal your Secret Recovery Phrase or private key.
