FREQUENTLY ASKED QUESTIONS

Answers to commonly asked questions


GETTING STARTED

How do I install MetaMask?


Go to MetaMask.io and click the “Download” button, which will take you to the
relevant store to download the extension or app based on the device and browser
you’re using.

I’m a MetaMask Extension user. How do I use the same wallet in MetaMask Mobile?


You can use the same MetaMask wallet on both Mobile and Extension.

Simply install MetaMask and import your existing wallet using your Secret
Recovery Phrase.

⚠️ Importing an existing wallet into a new installation of the MetaMask
extension and/or app is one of the only times you’ll ever need to input your
Secret Recovery Phrase. If any application or extension unexpectedly asks you
for your Secret Recovery Phrase, make sure you’re in the right place.

Do I need cryptocurrency to use MetaMask?


Technically, no. You can accept signature requests from sites without any value
in your account. Having cryptocurrencies in your MetaMask account (such as ETH,
ERC-20, ERC-721, or ERC-1155 tokens) will allow you to invest, trade, play
games, own unique digital items (NFT collectibles), and much more.

How do I get funds (digital currency) into MetaMask?


You can easily buy tokens directly within MetaMask by clicking “Buy”. Different
networks and payment methods are available, though your options will depend on
your region. You can also request funds from a friend by sending them a payment
request, showing your QR code in person, or by sharing your public address.

How do I transfer my existing ETH and tokens to MetaMask?


You can send ETH and tokens from another wallet to a new MetaMask account.
Simply copy your new MetaMask public address and go to your existing wallet or
exchange to send funds to your new wallet address.

You can find your MetaMask address under account name (in the format
0x12r45...6HJ9).

How do I send ETH and tokens?


Click/tap the “Send” button on your wallet homepage.


MANAGE MY DIGITAL ASSETS

Which tokens does MetaMask support?


ETH and any ETH-based token (ERC-20, ERC-721, and more). You may need to
manually import some tokens to see them within MetaMask.

Does MetaMask support NFTs?


Yes, although currently only on MetaMask Mobile. There is an “NFTs” tab on the
home screen of your mobile wallet.

Can I exchange my tokens?


Yes! Use our Swaps feature to swap tokens inside MetaMask.

Can I use a hardware wallet with MetaMask?


MetaMask currently supports Trezor, Ledger, Lattice, Keystone, and AirGap Vault
on Extension, and Mobile supports Keystone. We’re working on adding more
hardware wallets to Mobile.


PAYMENTS

What is my public address?


An Ethereum address is a unique identifier that serves as a virtual location for
your Ether and other tokens; think of it like your bank account number. See here
for more information.

How to deposit / receive / send?


On Mobile, tap the “Send” button on the homepage, or tap “Receive” to show your
QR code, copy your address, or request payment.

On Extension, you can also send by clicking the “Send” button. To receive funds,
copy your public address and paste it into the platform you’re sending from, or
share it with the sender.


SWAPS

How do I Swap tokens on MetaMask?


It’s as easy as hitting the Swap button, either on Extension or Mobile. Here’s a
quick demo to help you get started: https://youtu.be/zeu-a-W2qJQ

Why did my Swap fail?


A Swap may fail for various reasons, although the failure rate is low. The most
common is when a transaction runs 'out of gas'. The 'out of gas' error occurs
when all the gas that was allocated for the transaction is consumed before the
Swap could complete. To prevent an 'out of gas' transaction failure, we
recommend using the default Network Fee amount that is provided by MetaMask.
When a Swap fails, some of the gas fees may be consumed by the network, but the
asset you wished to swap from will remain in your MetaMask wallet.

If a Swap fails, your funds will always be safe in your wallet. If your Swap
fails more than once, please contact Support so we can investigate the
underlying cause.

Why can’t I find a token on MetaMask Swaps?


Behind the scenes, MetaMask Swaps automatically aggregates available liquidity
from leading DEXs and Professional Market Makers. If you can't find a token, it
likely lacks the sufficient amount of liquidity.

What is slippage?


Slippage refers to the difference between the expected price of a trade and the
price at which the trade is executed. Slippage is most prevalent with larger
orders and during periods of higher volatility.

Why do I need to approve a token before Swapping?


ERC-20 tokens are deployed with functionality that allows other smart contracts
to move tokens. By approving the smart contracts, it now has permission to
execute the peer to peer swapping behavior on your behalf. The Spend Limit
permission is the total amount of tokens that are able to move when using
MetaMask Swap. By default, we set the allowance to a high value, so you don't
have to approve your tokens every time you want to Swap, but you can always
configure a lower amount using a Custom Spend Limit.

Does MetaMask charge a fee on Swaps?


A service fee of 0.875% is automatically factored into each quote to support
ongoing development to make MetaMask even better.


SECURITY

How do I keep my wallet safe?


Backup your Secret Recovery Phrase

MetaMask requires that you store your Secret Recovery Phrase in a safe place. It
is the only way to recover your funds should your device crash or your browser
reset. We recommend you to write it down. The most common method is to write
your 12-word phrase on a piece of paper and store it safely in a place where
only you have access. Note: if you lose your Secret Recovery Phrase, MetaMask
can’t help you recover your wallet. Never give you Secret Recovery Phrase or
your private key(s) to anyone or any site, unless you want them to have full
control over your funds.

Use MetaMask on a personal device

MetaMask stores the Secret Recovery Phrase, passwords, and private keys in an
encrypted format locally on the device where it's installed.

How do I import my wallet into MetaMask?


With your wallet’s Secret Recovery Phrase. MetaMask can only load one Secret
Recovery Phrase at a time. If you already have a wallet, select the “import
Secret Recovery Phrase” option when you set up your wallet.

How do I import an account in MetaMask?


You can add an additional “loose” account (accounts added with a private
key/JSON file) to MetaMask using a private key or JSON file. Please note: your
Secret Recovery Phrase will not recover any “loose accounts”. Make sure to keep
BOTH your Secret Recovery Phrase and private keys (for any accounts not derived
from your Secret Recovery Phrase, such as imported accounts) securely stored to
recover all your accounts.

Lost my password: How do I restore my wallet?


If you cannot remember your password, you must restore your account using your
Secret Recovery Phrase and create a new password. See our article for more
information.

Lost my Secret Recovery Phrase: Can I restore my wallet?


The Secret Recovery Phrase is the last resort when it comes to recovering an
account. There are ways to try to find and restore the Secret Recovery Phrase on
a computer his requires access to the computer with the installation of MetaMask
or a backup of the computer.

your account address. You will see a MetaMask confirmation when websites request
access to view your account address.

Accessibility StatementCompliance status

We firmly believe that the internet should be available and accessible to anyone
and are committed to providing a website that is accessible to the broadest
possible audience, regardless of ability.

To fulfill this, we aim to adhere as strictly as possible to the World Wide Web
Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA
level. These guidelines explain how to make web content accessible to people
with a wide array of disabilities. Complying with those guidelines helps us
ensure that the website is accessible to blind people, people with motor
impairments, visual impairment, cognitive disabilities, and more.

This website utilizes various technologies that are meant to make it as
accessible as possible at all times. We utilize an accessibility interface that
allows persons with specific disabilities to adjust the website’s UI (user
interface) and design it to their personal needs.

Additionally, the website utilizes an AI-based application that runs in the
background and optimizes its accessibility level constantly. This application
remediates the website’s HTML, adapts its functionality and behavior for
screen-readers used by blind users, and for keyboard functions used by
individuals with motor impairments.

If you wish to contact the website’s owner please use the website's form

Screen-reader and keyboard navigation

Our website implements the ARIA attributes (Accessible Rich Internet
Applications) technique, alongside various behavioral changes, to ensure blind
users visiting with screen-readers can read, comprehend, and enjoy the website’s
functions. As soon as a user with a screen-reader enters your site, they
immediately receive a prompt to enter the Screen-Reader Profile so they can
browse and operate your site effectively. Here’s how our website covers some of
the most important screen-reader requirements:

 1. Screen-reader optimization: we run a process that learns the website’s
    components from top to bottom, to ensure ongoing compliance even when
    updating the website. In this process, we provide screen-readers with
    meaningful data using the ARIA set of attributes. For example, we provide
    accurate form labels; descriptions for actionable icons (social media icons,
    search icons, cart icons, etc.); validation guidance for form inputs;
    element roles such as buttons, menus, modal dialogues (popups), and others. 
    
    Additionally, the background process scans all of the website’s images. It
    provides an accurate and meaningful image-object-recognition-based
    description as an ALT (alternate text) tag for images that are not
    described. It will also extract texts embedded within the image using an OCR
    (optical character recognition) technology. To turn on screen-reader
    adjustments at any time, users need only to press the Alt+1 keyboard
    combination. Screen-reader users also get automatic announcements to turn
    the Screen-reader mode on as soon as they enter the website.
    
    These adjustments are compatible with popular screen readers such as JAWS,
    NVDA, VoiceOver, and TalkBack.
    
    
 2. Keyboard navigation optimization: The background process also adjusts the
    website’s HTML and adds various behaviors using JavaScript code to make the
    website operable by the keyboard. This includes the ability to navigate the
    website using the Tab and Shift+Tab keys, operate dropdowns with the arrow
    keys, close them with Esc, trigger buttons and links using the Enter key,
    navigate between radio and checkbox elements using the arrow keys, and fill
    them in with the Spacebar or Enter key.
    
    Additionally, keyboard users will find content-skip menus available at any
    time by clicking Alt+2, or as the first element of the site while navigating
    with the keyboard. The background process also handles triggered popups by
    moving the keyboard focus towards them as soon as they appear, not allowing
    the focus to drift outside.
    
    Users can also use shortcuts such as “M” (menus), “H” (headings), “F”
    (forms), “B” (buttons), and “G” (graphics) to jump to specific elements.

   jump to specific elements.

Additional UI, design, and readability adjustments
 1. Font adjustments – users can increase and decrease its size, change its
    family (type), adjust the spacing, alignment, line height, and more.
 2. Color adjustments – users can select various color contrast profiles such as
    light, dark, inverted, and monochrome. Additionally, users can swap color
    schemes of titles, texts, and backgrounds with over seven different coloring
    options.
 3. Animations – epileptic users can stop all running animations with the click
    of a button. Animations controlled by the interface include videos, GIFs,
    and CSS flashing transitions.
 4. Content highlighting – users can choose to emphasize essential elements such
    as links and titles. They can also choose to highlight focused or hovered
    elements only.
 5. Audio muting – users with hearing devices may experience headaches or other
    issues due to automatic audio playing. This option lets users mute the
    entire website instantly.
 6. Cognitive disorders – we utilize a search engine linked to Wikipedia and
    Wiktionary, allowing people with cognitive disorders to decipher meanings of
    phrases, initials, slang, and others.
 7. Additional functions – we allow users to change cursor color and size, use a
    printing mode, enable a virtual keyboard, and many other functions.

Assistive technology and browser compatibility

We aim to support as many browsers and assistive technologies as possible, so
our users can choose the best fitting tools for them, with as few limitations as
possible. Therefore, we have worked very hard to be able to support all major
systems that comprise over 95% of the user market share, including Google
Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS, and NVDA
(screen readers), both for Windows and MAC users.

Notes, comments, and feedback

Despite our very best efforts to allow anybody to adjust the website to their
needs, there may still be pages or sections that are not fully accessible, are
in the process of becoming accessible, or are lacking an adequate technological
solution to make them accessible. Still, we are continually improving our
accessibility, adding, updating, improving its options and features, and
developing and adopting new technologies. All this is meant to reach the optimal
level of accessibility following technological advancements. If you wish to
contact the website’s owner, please use the website's form
