# Advice and Answers from Keystone Team

## [General FAQ](/miscellaneous/faq)

<details>

<summary>Li-battery related EVERYTHING</summary>

For optimal charging of this product, it is recommended to acquire a USB type A charging adapter that delivers either a 5V1A or 5V2A output and to use the USB type A to USB type C charging cable with the product.&#x20;

The light indicator on the battery turns white when it's partially charged and yellow when fully charged.

The battery has a 1000mAh capacity and standby time of 1-2 days, but frequent usage may reduce it.

**Caution:**

1. An adapter with an output higher than 5V2A triggers a battery protection mechanism, and a lower than 5V1A may affect normal startup.
2. The battery does not support fast charging or charging via the laptop interface.

</details>

<details>

<summary>The Keystone device is not able to turn on using AAA batteries.</summary>

Keystone device requires **AAA 1.5V** batteries for proper operation.&#x20;

If your device is not turning on, please replace the existing 4 AAA batteries with new ones within the valid period. We suggest using rechargeable AAA batteries for better stability and compatibility with our device, but we do not recommend using Amazon Rechargeable Batteries as they may be prone to quick consumption.

<summary><strong>Which cryptocurrencies and tokens does Keystone support?</strong></summary>

Keystone supports a range of digital assets including BTC, ETH, SOL, NEAR, BNB, POLYGON, APTOS, DOT, KSM, XRP, LTC, DASH, BCH, AR, and TRON.\
\
To make it easier to manage your assets, Keystone only displays the main-chain assets. You can add and manage additional tokens via the mobile app.\
\
Support for ATOM, and ADA is coming soon.\
\
A list of currently [Supported Assets and Wallets](https://keyst.one/supported-wallets-and-assets) can be found on our website.

<details>

<summary><strong>Is it possible to import a recovery phrase generated by a different wallet into Keystone?</strong></summary>

Keystone supports 12/18/24-word recovery phrases generated by any BIP39 wallet.

</details>

<details>

<summary>Keystone supports 12/18/24-word recovery phrases generated by any BIP39 wallet.<strong>Can I use a different brand of a hardware wallet to recover my assets if my Keystone is lost or damaged?</strong></summary>

Keystone requires users to have complete control and ownership of their private keys (recovery phrase). If the Keystone device is lost or damaged, the Secure Element will protect the private keys from being exposed. The Keystone Pro also has a self-destruct mechanism that automatically erases all information, including private keys, if the device is disassembled.\
\
Different brands of hardware wallets use different derivation paths, so if you import the recovery phrase into a hardware wallet of a different brand, some of the assets on certain addresses may not be visible or accessible. If your Keystone is lost or broken, it is recommended to recover your assets using a wallet with the same derivation path as Keystone.\
\
If you have any additional concerns, please contact the [Keystone Support Team](https://keystonewallet.atlassian.net/servicedesk/customer/portal/1). Our administrators will assist you as soon as possible.

# General Navigation Guide

This page will help you navigate the various features based on your user profile (Beginners, Bitcoiners, Web3 Users, Advanced users).&#x20;

Please kindly note that this is not a 101 guide on crypto. We assume you already understand basic concepts like seed phrases, private keys, addresses and have some experience with software wallets.

## Beginners

For beginners, the first and ultimate thing you should remember is to NEVER share your seed phrase to ANYONE. Some of the common tricks by scammers include:

1. DM you on social media with our team member's profile to ask you to share your seed phrase or share a  website link to collect that info.
2. Buy ads on social media or search engines for their phishing sites to collect your seed phrase or register similar domains expecting you to enter sensitive data.

As a beginner, feel free to follow these tutorials to easily utilize your Keystone hardware wallet with its companion app to achieve 100% air-gapping security when sending and receiving cryptocurrencies.

# About Keystone

<figure><img src="https://miro.medium.com/max/2048/1*edNZoGr4D_ab9Bput3K3_w.png" alt="Keystone-2"><figcaption></figcaption></figure>

Keystone Hardware Wallet is a 100% Air-gapped QR code communication hardware wallet for Bitcoin, Ethereum, USDT, BCH, XRP, Tron, LTC, Dash, Polkadot, Kusama and 1000+ cryptocurrencies.

It offers convenient cold storage solution with an open source firmware, 4 inch touchscreen and PSBT Bitcoin multisig support. Protect your cryptocurrency with the perfect balance between secure and convenient hardware wallet with mobile phone support.

These are the full feature highlights of the Keystone Essential and Pro.

<figure><img src="/files/-MbnhG_q-tzJlG1paIUC" alt="Keystone-Air gapped"><figcaption></figcaption></figure>

All hardware wallets need some means of connecting to the network to sign transactions; how “air-gapped” your hardware wallet is depends on how it limits the attack surface when transmitting data to an internet-enabled device. QR codes have a smaller attack surface than USB, NFC, and Bluetooth, making them the perfect means of data transmission for an air-gapped hardware wallet. We have pioneered an animated QR code solution that enables transmission of larger amounts of transaction data and have also developed microSD card capability as requirements for compatibility with desktop wallets like Electrum and Wasabi are more demanding.

<figure><img src="/files/-Mbnid1tW1grTS0vLhzU" alt="Keystone-QR codes"><figcaption></figcaption></figure>

With QR codes, you can verify each and every data transmission to ensure that information coming into the Keystone Hardware Wallet contains no trojans or viruses and information going out doesn’t leak private keys or any other sensitive information. In contrast to USB or Bluetooth, QR codes are entirely [verifiable](https://blog.keyst.one/ever-wondered-what-your-hardware-wallet-inputs-and-outputs-9b33b4cedafd) as any normal QR code scanner can convert their data contents into human-readable format.

<figure><img src="/files/-Mbnilwh1U3Mn3t2YPB5" alt="Keystone-Secure Element"><figcaption></figcaption></figure>

Keystone Hardware Wallet uses a bank-grade Secure Element to [generate true random numbers](https://blog.keyst.one/secure-elements-harnessing-a-force-of-nature-14a959da7b54), derive private and public keys, sign transactions, and [protect private keys](https://blog.keyst.one/secure-elements-the-last-line-of-defense-4669012d4edc) from being leaked if an attacker has physical access to the device. In addition to ensuring your keys really are your keys by sourcing them from physical entropy, a Secure Element is vital to storing your private keys with the best possible protection from physical attack. A hardware wallet equipped with a Secure Element is a foundation of security long-term hodlers can rely on.

<figure><img src="/files/-MbnipmQvmgaD5brO0Uc" alt="Keystone-Open Source"><figcaption></figcaption></figure>

Keystone Hardware Wallet is the first hardware wallet to have open source Secure Element firmware code, which allows you to verify all core cryptographic operations such as how private keys are generated and contained entirely within the Secure Element. You are able to compile the open source Secure Element firmware and hardware wallet application layer code available on our Github page if you want to verify the genuinity of firmware upgrade packages for Keystone Essential and Pro yourself. We have also released the device schematic circuit diagram.

<figure><img src="/files/-MbnjZPvaApQq2NAhcnh" alt="Keystone-Battery"><figcaption></figcaption></figure>

The weakest link in an electronic device tends to be the battery because it’s usually only built to last a few years. Keystone batteries are detachable to prevent corrosion damage and both Keystone Essential and Pro come with AAA battery support so you never have to worry about battery failure down the road. Keystone Pro also comes with a rechargeable battery.

Be aware AAA battery voltage is not steady, which is why it is generally used for products that do not need a constant voltage, like remote controllers. The AAA battery support option is intended for infrequent use. If you are likely to turn on your hardware wallet more than a couple of times a month, we recommend getting Keystone Pro.

<figure><img src="/files/-MbnjhX6pMDaMxkiIm4A" alt="Keystone-Fingerprint"><figcaption></figcaption></figure>

More sophisticated hardware wallet owners may have multiple devices used for different purposes. Keystone Pro has a fingerprint sensor option that can be used to take care of business in public locations like cafes or airports to prevent your passwords from being stolen by onlookers or surveillance cameras. Fingerprint authentication for device unlock and transaction signing can be toggled off in settings at the user’s discretion.

<figure><img src="/files/-MbnlW9Uaox_eY1ghIXG" alt="Keystone-Secure Strategy"><figcaption></figcaption></figure>

Hardware wallets are more vulnerable when you take them around with you. To prevent a side-channel attack from succeeding if you lose your device, we designed a multilayered [self-destruct mechanism](https://blog.keyst.one/self-destruct-mechanisms-unique-defense-against-side-channel-attacks-4cfea3d4eff1) for Keystone Pro. Upon detection of disassembly, the self-destruct mechanism will wipe the private keys and any sensitive information so that an attacker cannot extract it from your device.

<figure><img src="/files/-Mbnl_Kn7DqIZTs-wFDW" alt="Keystone-Multicoins support"><figcaption></figcaption></figure>

Keystone Hardware Wallet supports BTC, ETH, USDT, BCH, XRP, TRON, LTC, DASH, DOT and KSM. ETH and TRX tokens are also supported. View our full list of supported coins and tokens [here](https://keyst.one/supported-crypto-assets). If you are interested in a Bitcoin-only hardware wallet, a [Bitcoin-only firmware version](https://keyst.one/firmware) for upgrading Keystone Essential and Pro is also available.

<figure><img src="/files/-MbnmkWydIFNOcoMf3L8" alt="Keystone-Compare"><figcaption></figcaption></figure>

Keystone Essential is intended for long-term hodlers and comes with AAA battery support for 119 USD. Keystone Pro is designed for more portable access to funds and comes with a rechargeable battery, fingerprint sensor, and self-destruct mechanism for 169 USD. Shipping is free to the United States and Canada.

## I. **Web Authentication**

**Preparation**：① Keystone  ② Laptop or Phone

1\. Press and hold the “Power” button for 3s to boot Keystone.

2\. Choose a system language and tap \[Next].

<figure><img src="/files/-MXkdpaZtw8ufk_CxKe8" alt="Keystone-Web Authentication-1"><figcaption></figcaption></figure>

3\. Visit [Keystone official website](https://keyst.one/authentication) on your laptop or mobile phone. Click \[Authenticate] to display the Web Authentication QR code. Please adjust QR code size with the slide bar if Keystone has trouble scanning the QR code.

<figure><img src="/files/-Mb5xTa5dVMPOVbBXShp" alt="Keystone-Web Authentication-2"><figcaption></figcaption></figure>

4\. Tap \[Scan QR Code] on your Keystone device. Scan the QR code displayed on the "Web Authentication" page of the official website and Keystone will show the 8-digit verification code.

<figure><img src="/files/-Mb9irJSsazJ1fwGPn6E" alt="Keystone-Web Authentication-3"><figcaption></figcaption></figure>

5\. Input the 8-digit code shown on your Keystone on the website and click \[Verify].

<figure><img src="/files/-Mb9ivf5VZQEBTzrAS29" alt="Keystone-Web Authentication-4"><figcaption></figcaption></figure>

6\. If the web page says “Your Device is Secure!”, tap \[Success] on your Keystone device.

<figure><img src="/files/-MbK02QOk8xTkbYfhUDH" alt="Keystone-Web Authentication-5"><figcaption></figcaption></figure>

{% hint style="info" %}
Web Authentication helps prevent supply chain attacks. If the device has been tampered with, authentication will fail. For more information on how Web Authentication works, visit our [blog](https://blog.keyst.one/web-authentication-a-counter-to-supply-chain-attacks-62d0272f656b).&#x20;
{% endhint %}

## **II. Set a Strong Password**

1\. Password Length: At least 10 characters.

2\. Must include upper and lower case letters and digits, symbols are allowed.

<figure><img src="/files/-MXB-KhsCa1YJwzKzWnp" alt="Keystone-GetStarted-1"><figcaption></figcaption></figure>

{% hint style="info" %}
After the Keystone imports a recovery phrase, the password can be used to sign transactions (private keys will call a password for signature). This means your cryptocurrencies can be sent out if your password is leaked. Please set **a strong password** instead of using simple passwords like names or birthdays as this may make it easier for an attacker to brute force it and access your recovery phrase.
{% endhint %}

## **III. Creating or Importing a Wallet & Recording the Recovery Phrase**

**Preparation**: Recovery phrase paper or metal tablet&#x20;

{% hint style="danger" %}
**Caution: You are not recommended to perform this step in public places or with others.**
{% endhint %}

### 1. Create a Wallet

If you do not have a recovery phrase or need to generate a new recovery phrase, please select \[Create Wallet]. &#x20;

a. Tap \[Create Wallet], then \[Next], then \[I UNDERSTAND] (please read the prompts on the Keystone carefully).

<figure><img src="/files/-Mcr1KB6YnEIppAIU_Lv" alt="Keystone-GetStarted-2"><figcaption></figcaption></figure>

b. Carefully record the recovery phrase while it is being displayed. You may want to use a metal tablet for more permanence.

<figure><img src="/files/-MXAyNzbWhr-Y4qpsa-1" alt="Keystone-GetStarted-3"><figcaption></figcaption></figure>

c. Tap \[Recovery Phrase Saved], then \[Next Step].

<figure><img src="/files/-MXAyT3rfx8s1Z5KKOXb" alt="Keystone-GetStarted-4"><figcaption></figcaption></figure>

d. Input the recovery phrase and tap \[Confirm] to create the wallet.

<figure><img src="/files/-MXB7BNRaxRSi4DC9v2i" alt="Keystone-GetStarted-5"><figcaption></figcaption></figure>

### 2. Import Wallet

If you already have a recovery phrase, you can select \[Import Wallet]. We recommend users create a new recovery phrase when beginning use of the Keystone to isolate assets from risks associated with previous use of an old recovery phrase (such as having entered it on a mobile phone connected to the internet or taking and saving pictures of the recovery phrase on a mobile phone, etc.).

a. Tap \[Import Wallet], then tap \[Import a Wallet with Single Backup].

<figure><img src="/files/-MXB8YPJ_CzXaZ-Fzwyh" alt="Keystone-GetStarted-6"><figcaption></figcaption></figure>

b. Carefully record the recovery phrase while it is being displayed. You may want to use a metal tablet for more permanence. Select recovery phrase length and tap \[Next].

<figure><img src="/files/-MXBBr4Not5l0_CQGwiY" alt="Keystone-GetStarted-7"><figcaption></figcaption></figure>

c. Enter your recovery phrase. Tap \[Import Wallet] to start creating a wallet. Then tap \[Confirm].

<figure><img src="/files/XHquP1YYftiu36rkTa33" alt="Keystone-GetStarted-8"><figcaption></figcaption></figure>

{% hint style="info" %}
Keystone supports importing 12/18/24-word recovery phrases and generating 24-word recovery phrases by default.
{% endhint %}

{% hint style="info" %}
The recovery phrase entails complete ownership of the cryptocurrency. If your Keystone is lost or stolen, the recovery phrase is the only way to retrieve your assets. Please make sure you have physically backed up your recovery phrase instead of saving it as a photo or other format on any device which may connect to the internet. Air-gapped mobile phones, laptops, and USB sticks have [larger attack surfaces](https://blog.keyst.one/air-gapped-computers-and-phones-vs-hardware-wallets-whats-the-difference-458888cdd97), so we advise against using them.
{% endhint %}

## **IV. Add Assets**

1\. Select the Assets you need to manage.

2\. Tap the \[√] icon on the top right of the page.

<figure><img src="/files/-MXBD02Pd0Bk-ng15ANr" alt="Keystone-GetStarted-9"><figcaption></figcaption></figure>

{% hint style="info" %}

[Setting Up Keystone (Legacy)](/getting-started/setting-up-keystone-in-5-steps)
{% endcontent-ref %}

## Foreword

The Keystone Hardware Wallet will help you create your cryptocurrency wallet in a secure and offline environment.&#x20;

Now, let‘s get to [know your Keystone](https://support.keyst.one/) and properly set it up to secure your crypto.

## Preparation

1\. Keystone with battery level 70% or above.&#x20;

2\. Computer: For visiting the online beginner's guide, interact with the provided web authentication tool, and download the firmware upgrade file.&#x20;

3\. A MicroSD card (Default FAT32 format and capacity not exceeding 512GB.）&#x20;

4\. A MicroSD card reader (Not necessary if your laptop has a microSD card port.)

5\. Recovery phrase paper or metal tablet: For storing your recovery phrase (seed or secret words).&#x20;

## Step 1. Web Authentication

1\. Press and hold the “Power” button for 3s to boot up your Keystone.

2\. Choose a system language, in this case, \[English], then select \[Next] > \[It's ready, start].

<figure><img src="/files/Z9Tffb870SoFyyU9HgmP" alt="Keystone-New-GetStarted-1"><figcaption></figcaption></figure>

3\. Visit [Web Authentication interface](https://keyst.one/authentication?locale=en) on Keystone's official website on your laptop or mobile phone. Click \[Authenticate] to display the Web Authentication QR code.&#x20;

Web Authentication tools help prevent supply chain attacks. If the device has been tampered with in any way, the authentication will fail. For more information on how Web Authentication works, visit our [blog](https://blog.keyst.one/web-authentication-a-counter-to-supply-chain-attacks-62d0272f656b).
{% endhint %}

## Step 2. Set a Strong Password

1\. Password Length: At least 10 characters.

2\. Must include upper and lower case letters and digits. symbols are allowed.

<figure><img src="/files/vinOif2hmNIqZisb39yw" alt="Keystone-New-GetStarted-7"><figcaption></figcaption></figure>

{% hint style="info" %}
**Did you know?**&#x20;

After the Keystone imports a recovery phrase, the password can be used to sign transactions (private keys will call a password for signature). This means your cryptocurrencies can be sent out if your password is leaked. Please set a strong password instead of using simple passwords like names or birthdays as this may make it easier for an attacker to force their access to your recovery phrase.
{% endhint %}

## Step 3. Firmware Upgrade&#x20;

Upgrading your firmware to the latest version allows you to benefit from new features and is highly recommended.

#### **A.** You can click the page link below to check the specific operation in the firmware upgrading tutorial for :

&#x20;([How to Format a MicroSD Card to FAT32?](https://support.keyst.one/getting-started/firmware-upgrading#iv.-how-to-format-a-microsd-card-to-fat32))
{% endhint %}

## Step 4. Creating or Importing a Wallet&#x20;

**Preparation:** Recovery phrase paper or metal tablet.

{% hint style="danger" %}
**Caution:**

1. Performing the following steps in public places or with others around is NOT recommended.
2. Be sure to write down and store your recovery phrase (seed or secret words) in secure locations.
   {% endhint %}

### 1. Create a Wallet&#x20;

If you do not have a recovery phrase or need to generate a new recovery phrase, please select \[Create Wallet].

a. Tap \[Create Wallet], then enter the password and tap \[Confirm], then tap \[Create a Wallet with Single Backup] > \[I UNDERSTAND] (please carefully read the prompts on your Keystone device).

<figure><img src="/files/kynxUCntOTHjDkjxG64Z" alt="Keystone-New-GetStarted-11"><figcaption></figcaption></figure>

b. Carefully record the recovery phrase while it is being displayed. You may want to use a metal tablet for more permanence. Then select \[Recovery Phrase Saved] > \[Next Step].

<figure><img src="/files/nzJQevGsuiYO30fst0l2" alt="Keystone-New-GetStarted-12"><figcaption></figcaption></figure>

<figure><img src="/files/1GCTFpTBD27BdkNSxE8i" alt="Keystone-New-GetStarted-13"><figcaption></figcaption></figure>

c. Input the recovery phrase and select \[Confirm] to create the wallet.

<figure><img src="/files/0rpd1LQKQ8mqcGijKWyH" alt="Keystone-New-GetStarted-14"><figcaption></figcaption></figure>

### 2. Import Wallet&#x20;

If you already have a recovery phrase, you can select \[Import Wallet].

![](/files/dF12tvmBIRsXqhusheF2)

**Tip:** Keystone supports importing 12/18/24-word recovery phrases and generating 24-word recovery phrases by default.

{% hint style="info" %}
**Did you know?**&#x20;

The recovery phrase entails complete ownership of the cryptocurrency. If your Keystone is lost or stolen, the recovery phrase is the only way to retrieve your assets. Please make sure you have physically backed up your recovery phrase instead of saving it as photo or other format on any device which may connect to the internet. Air-gapped mobile phones, air-gapped laptops, and USB sticks have [larger attack surfaces](https://blog.keyst.one/air-gapped-computers-and-phones-vs-hardware-wallets-whats-the-difference-458888cdd97) so we strongly advise against using them to save your recovery phrase.&#x20;
{% endhint %}

## Step 5. Choose the Proper Companion App and **Add Assets**

Once you have successfully created/imported a wallet on your Keystone device, you can select a companion software wallet. This allows you to view your balance and create transactions.

1\. Select a proper companion software wallet based on your needs. In this tutorial, we’ll be selecting the \[Keystone Companion App] and show you how to pair your Keystone device with the Keystone Companion App in Step 6.

2\. Select the \[Cryptocurrency] you want to manage and tap the \[√] icon on the top right corner of the screen.

![](/files/5avndeUFiw5vVONBQ17C)

3. If the pop-up doesn't appear, you can access the menu button and navigate to \[Settings], then tap \[Version]. If that doesn't work, try restarting the device and attempting again.

<figure><img src="/files/McDpKeuZJjJkcP1TVRlH" alt=""><figcaption></figcaption></figure>

## Unable to upgrade the firmware?&#x20;

Please consider the following troubleshooting steps:

1. Insert the MicroSD card correctly by gently pressing it into the card slot until you hear a click, ensuring it is properly inserted.
2. Make sure that the only file on your MicroSD card is the "update.zip" file. Remove any other files like "M-10.2" or "B-3.4" to allow the device to directly read the intended file.
3. If the "Firmware Update" info doesn't appear, restart the device.
4. Verify that your MicroSD card is formatted to FAT32 and does not exceed 512GB in size.
5. If the problem persists, try using a different MicroSD card. We typically recommend using SanDisk Ultra cards.
6. Double-check that you have downloaded the correct file. If your terminal version is "BTC-Only," ensure that you have downloaded the "Multi-coin to BTC-Only" version.

# Keystone Mobile App Syncing

{% hint style="info" %}
Important Note: Please follow the updated tutorial if the firmware version is newer than M-9.8.
{% endhint %}

## I. **What is the purpose of the** Keystone Mobile Ap&#x70;**?**

As you might already know, the Keystone Hardware Wallet is completely offline and 100% air-gapped, which means it is not connected to the blockchain so it cannot show you how many coins you have not created any transactions on it.&#x20;

This is where the app comes into play. The Keystone Mobile App is designed to be paired with the Keystone Hardware Wallet to easily view all of your coins and create transactions.

Users can easily pair their Keystone devices with the Keystone Mobile APP via a QR code so your APP would have all of your public addresses associated with your device. The addresses sync up with the blockchain and allow you to view your balances and create transactions.&#x20;

## II. Operation

**Preparation:** Download the Keystone Mobile App from Google Store or App Store

1\. Open the Keystone mobile app and tap \[Bind]. Scan the QR code displayed on the Keystone hardware wallet.

<figure><img src="/files/-Mb5thCaFhjBlRHVp6E9" alt="Keystone-AppSyncing-1"><figcaption></figcaption></figure>

**Tips:**

1\) If you have already initialized your device, Please touch the \[•••] icon > \[Connect Software Wallet] to show the QR code.

<figure><img src="/files/ImMUmaLzdG1R6BiUxNip" alt="Keystone-AppSyncing-2"><figcaption></figcaption></figure>

2\) If the data is large, the number of QR codes will increase. Please keep scanning until the process finishes. If you have problems scanning due to the size of the QR code presented, please touch the QR code and use the "zoom in/out" tool to help with the scanning process. If you still have problems with scanning, please[ submit a request](https://keyst.one/request) to us. Our support staff will reply to you ASAP.

# Receiving Cryptocurrency

Both Keystone hardware wallet and the Keystone mobile app support displaying receiving addresses. If you wish to minimize use of your hardware wallet, you can have your receiving addresses displayed on the mobile app.

## I. Keystone **Hardware Wallet**

1\. Tap \[Assets] on the main page.

<figure><img src="/files/5NXsJlT5FiYVZOcqUHUF" alt="Keystone-FundsReceiving-1"><figcaption></figcaption></figure>

2\. Tap an address to display address details including the QR code and the derivation path.

<figure><img src="/files/-MXfi8bKGYOJhdPOoIh5" alt="Keystone-FundsReceiving-2"><figcaption></figcaption></figure>

[How can I create new addresses to receive cryptocurrency?](https://support.keyst.one/basic-features/adding-multiple-addresses)

Because token addresses are the same as main-chain addresses, you can use the main-chain address to receive tokens of the same cryptocurrency. For example, you can use ETH addresses to receive USDT-ERC20. [Add Tokens](https://support.keyst.one/basic-features/adding-tokens-on-the-mobile-app) on the mobile app to help with management.

## II. Keystone **Mobile App**

1\. Go to the corresponding wallet and tap \[Cryptocurrency] > \[Receive].

<figure><img src="/files/-MXknPdTiQUjDDGZ3iPc" alt="Keystone-FundsReceiving-3"><figcaption></figcaption></figure>

2\. Tap \[Address] to change the receiving address.

<figure><img src="/files/-MXfihGPMkXsjuInnbuP" alt="Keystone-FundsReceiving-4"><figcaption></figcaption></figure>

3\. There are 2 ways to share address information to a sender: (Please use addresses displayed on the Keystone device to verify receiving addresses, or scan the QR code format of the address displayed on the Keystone device when receiving.)

a. Hold down on the address to copy it to the clipboard.

b. Show the address’s QR code to the sender.

<figure><img src="/files/fWIOoDy94Rw8JePzT5D9" alt="Keystone-FundsReceiving-5"><figcaption></figcaption></figure>

## **III. Receive Mining Proceeds**

1\. If you use the Keystone hardware wallet’s addresses to receive BTC, LTC, DASH, or BCH mining proceeds, you may receive a large amount of small transactions. Transaction data and transaction fees will increase with the number of UTXOs sent at the same time.

2\. We suggest you use the HD wallet to generate mining proceeds receiving addresses, and regularly transfer to your hardware wallet. For example, if you receive 100 transactions of 0.0001 BTC, we recommend you send them in 1 transaction of 0.1 BTC to your hardware wallet address.

# Specter 2/3 PSBT Multi-Sig

Keystone firmware versions V1.1.1 (BTC-Only) or newer support PSBT Multi-signature functions. Detailed instructions below will explain how to create a 2-out-of-3 PSBT Multi-signature wallet with the Keystone Wallet, Coldcard and a [SeedPicker](http://seedpicker.net/) as 3 participant co-signers. We will use here Specter V1.4.6 as the watch-only coordinator.

## I. **Preparation**

1\. [Firmware](https://keyst.one/firmware?locale=en) version V1.1.1 (BTC-Only) or newer running on Keystone Essential or Pro models. Create recovery phrase A.

&#x20;  (Please read[ How to upgrade firmware](https://support.keyst.one/getting-started/firmware-upgrading) for more details.)

2\. Coldcard upgraded to firmware version V2.1.0 or newer.&#x20;

3\. <http://seedpicker.net/> run on an offline PC/Mac.

3\. Specter (V1.4.6 or newer) installed and running on PC/Mac.

4\. MicroSD card (≤512GB; default FAT32 format).

### 3. Adding Paper Wallet on Specter

By using a software-generated paper wallet, you eliminate the need to buy a third hardware wallet (you may later have to buy a hardware wallet if you need to use this key for emergency recovery purposes).

In this tutorial, we chose to use [SeedPicker](http://seedpicker.net/) to generate the third recovery phrase.

{% hint style="warning" %}
**Warning: This is the highest risk step in our multisig setup**. **Follow the instructions closely to drastically improve your security.**
{% endhint %}

1\) Insert the microSD card into your PC/Mac.

## III. Sending and Receiving Assets with Sparrow Wallet

### **A. Receiving BTC**

Users can choose between the Keystone device or the Sparrow Wallet app to generate receive addresses for BTC. But it’s recommended to use Keystone to view or generate receive addresses due to safety concerns. (This way you can verify that the receiving address is actually correct or not, because the internet-connected instance is prone to malware.)

1\. On Keystone: Touch \[Addresses] to display the receiving addresses. (You can optionally generate more addresses that the device can display for you.)

<figure><img src="/files/-McN5lolERq4Ia2K1r88" alt="Keystone-Sparrow-13"><figcaption></figcaption></figure>

2\. On Sparrow Wallet: Click \[Receive] to display the receiving addresses. (You can also go into the Addresses menu and use any address displayed, but we mainly recommend using the ones via Receive.)

<figure><img src="/files/-McN6-awKvJbI6kdf-Ff" alt="Keystone-Sparrow-14"><figcaption></figcaption></figure>

### **B. Sending BTC**

#### 1. Create a Transaction with Sparrow Wallet

{% hint style="info" %}
**Notes:**

1\. Electrum cannot recognize dynamic QR codes, static QR codes that only have the capacity for around 8 inputs, 2 outputs, and corresponding signing data (capacity may be affected by differences in screen resolution and camera on the device used for Electrum). When transaction data is too large to be transmitted via static QR code or Keystone is unable to recognize/display a QR code, please use your own microSD card to transmit transaction data.

2\. Keystone automatically checks and marks the changed address for you as a security measure against phishing attacks on Electrum, which may attempt to insert different addresses that do not belong to you. However, these functions only work for the first 100 changed addresses that Keystone creates by default, and will not continue working for changed addresses that you create after initializing the device. Later, we will add support to manually add an unlimited number of changed addresses to the list that Keystone will check for in Electrum transactions.

# MetaMask

Keystone is the only hardware wallet that is compatible with both the MetaMask extension and the MetaMask mobile app. It fully supports all EVM chains, as well as the main coins, tokens, and Dapps.

🎉🎉🎉<mark style="background-color:orange;">Great news!</mark>&#x20;

<mark style="background-color:orange;">The waitlist for our 3rd generation product is now open. Visit our</mark> [<mark style="background-color:orange;">homepage</mark>](https://keyst.one/) <mark style="background-color:orange;">to find out more.</mark>

Firmware versions M-5.0 (Multi-Coin) or newer will allow you to use the MetaMask Extension (V10.8.0 or newer) with your Keystone and set the MetaMask extension as a watch-only wallet on your Keystone Essential or Pro.

## **I. Preparation**

1\. [Firmware](https://keyst.one/firmware?locale=en) versions M-5.0 (Multi-Coin) or newer running on Keystone Essential or Pro.&#x20;

&#x20;  (Please read[ How to upgrade firmware](https://support.keyst.one/getting-started/firmware-upgrading) for more details.)

2\. Download the MetaMask browser extension (**V10.8.0 or newer**) from MetaMask's [official website](https://metamask.io/download).&#x20;

## **II.Important Notes**

A wallet generated by MetaMask has its recovery phrase online. This means that this recovery phrase has been connected to the network(internet).

Therefore, even if you import this recovery phrase created by MetaMask into Keystone (or any other hardware wallets) to continue managing your digital assets, this recovery phrase might already be at risk of being attacked by hackers.

{% content-ref url="/pages/za1waTlj0y6kWl5UkulY" %}
[Potential Trouble with Importing MetaMask wallet into Keystone](/3rd-party-wallets/eth-and-web3-wallets-keystone/bind-metamask-with-keystone/potential-trouble-with-importing-metamask-wallet-into-keystone)
{% endcontent-ref %}

{% hint style="danger" %}
In principle, we highly recommend creating a new recovery phrase (new wallet with a 24-word seed phrase) offline on a Keystone hardware wallet and then transferring your assets from your MetaMask wallet to the new one prior to using your Keystone to interact with MetaMask. This is the safest way to protect your assets.
{% endhint %}

## **III. Bind MetaMask** **with your Keystone Hardware Wallet**

#### **1. Set Up Your MetaMask**

1\) If you are running any fork of MetaMask other than the standard production fork, disable it now.

<figure><img src="/files/uq4nN9o3uBfl75TDeaWk" alt="Keystone-MetaMask-1"><figcaption></figcaption></figure>

3\) Choose to either create a new MetaMask wallet or import one. Here we will create a new Secret Recovery Phrase as a demonstration.&#x20;

<figure><img src="/files/9u13l617UtvFZzc4HGvT" alt="Keystone-MetaMask-2"><figcaption></figcaption></figure>

4\) Set up your password. Please try to set a strong password to maximize the security of your account.

<figure><img src="/files/8xdjl5K1S6E6rCQttoLF" alt="Keystone-MetaMask-set-up"><figcaption></figcaption></figure>

5\) Keep your secret recovery phrase somewhere safe.

# Importing MetaMask Wallet into Keystone

By using the official MetaMask extension (V10.8.0 or newer), users can import their existing MetaMask wallet into their Keystone hardware wallets (with M-5.0 or newer firmware versions) and continue to manage their assets in the same wallet by utilizing MetaMask as a watch-only wallet.

{% hint style="danger" %}
In principle, we highly recommend creating a new recovery phrase (new wallet with a 24-word seed phrase) offline on a Keystone hardware wallet and then transferring your assets from your MetaMask wallet to the new one prior to using your Keystone to interact with MetaMask. This is the safest way to protect your assets.
{% endhint %}

## I. Operation

This section will explain, step-by-step, how to import an existing MetaMask account into your Keystone and then interact with MetaMask using your Keystone to manage your assets on particular accounts.

1.Run the “MetaMask Extension” and enter the main interface. Then, check the MetaMask wallet you want to import to Keystone. In this tutorial, we will import the wallet labeled as “Account 1” into Keystone.

<figure><img src="/files/PTExcy0HMAZy1P7ULgVR" alt="Keystone-MetaMask-LedgerPath-1"><figcaption></figcaption></figure>

2\. Obtain the secret recovery phrase for your MetaMask wallet (in this case, the recovery phrase for “Account 1”).

If you have forgotten your secret recovery phrase, you can reveal it as follows：

*1) Click on the "Menu" icon on the top right corner > then select \[Setting] > \[Security & Privacy] > \[Reveal Secret recovery phrase].*

<figure><img src="/files/rPJGUeQ3R8afdw8OWo9A" alt="Keystone-MetaMask-LedgerPath-2"><figcaption></figcaption></figure>

<figure><img src="/files/fsANdFfhVy8a8arUJ9e5" alt="Keystone-MetaMask-LedgerPath-3"><figcaption></figcaption></figure>

*2) Enter your password and click on \[Next] to display the secret recovery phrase. Then, carefully record it. We suggest to use a metal tablet for high permanence.*

<figure><img src="/files/8e9gOxthEyimt81SdmCK" alt="Keystone-MetaMask-LedgerPath-4"><figcaption></figcaption></figure>

<figure><img src="/files/LnEx93ThBEEwv2NA4v52" alt="Keystone-MetaMask-LedgerPath-5"><figcaption></figcaption></figure>

3\. Turn on the Keystone device. Tap the "Menu" icon > \[Setting] > \[Create/Import Wallet] > Ether your password and tap \[Confirm].

<figure><img src="/files/CsEfbbRzQFw1CQPlGbY4" alt="Keystone-MetaMask-LedgerPath-6"><figcaption></figcaption></figure>

4\. Select \[Import Wallet] > \[Import a Wallet with Single Backup], then select the proper recovery phrase length (in this case, 12) and tap \[Next].

<figure><img src="/files/PLhWOV4MDCGsQFfTNsDf" alt="Keystone-MetaMask-LedgerPath-7"><figcaption></figcaption></figure>

5\. Enter your recovery phrase > tap \[Import Wallet] to finish importing wallet > add any cryptocurrencies to the list based on your needs and tap \[√]. Now, your MetaMask Account has been successfully imported.

<figure><img src="/files/9WmnoxrGFopkCrXzp4MA" alt="Keystone-MetaMask-LedgerPath-8"><figcaption></figcaption></figure>

6\. Click on the "Menu" icon > \[Software Wallet] > select  \[MetaMask / Rabby / DeFi] and tap \[Confirm] > tap \[Export Later] to enter the wallet homepage. Check whether the “Account 0” address on Keystone and MetaMask are the same.

<figure><img src="/files/8k0pZB8hAcrK96A4ZqVJ" alt="Keystone-MetaMask-LedgerPath-9"><figcaption></figcaption></figure>

7\. Tap the \[•••] button on the top right of the screen > then tap \[Connect Software Wallet] to display the QR code.

<figure><img src="/files/ACV8ah5Qzt3onFQecD3F" alt="Keystone-MetaMask-LedgerPath-10"><figcaption></figcaption></figure>

**8. Uninstall and reinstall the MetaMask extension. (This is a necessary and important step.** For more information, please see the [Potential Trouble with Importing Accounts](https://support.keyst.one/3rd-party-wallets/eth-and-web3-wallets-keystone/bind-metamask-with-keystone/potential-trouble-with-importing-metamask-wallet-into-keystone).**)**

9\. Run the “MetaMask Extension” and **set up MetaMask by creating a new Secret Recovery Phrase**. (After setting up and entering the main interface, you will see a new MetaMask account. This new account has nothing to do with your old MetaMask account so you can simply disregard it.)

<figure><img src="/files/ANaxakJIxwIGA7PCP7rN" alt="Keystone-MetaMask-LedgerPath-14"><figcaption></figcaption></figure>

11\. Select \[QR-based] and then click \[Continue].

<figure><img src="/files/7Y76ldeLHRAqiEWeUox3" alt="Keystone-MetaMask-LedgerPath-15"><figcaption></figcaption></figure>

12\. MetaMask uses your computer's camera to scan the QR code displayed on the Keystone hardware wallet.

<figure><img src="/files/UGa6YuobfSMbHvY1Ax3v" alt="Keystone-MetaMask-LedgerPath-16"><figcaption></figcaption></figure>

13\. Select the Account (e.g. Account 1) that you want to bind and click \[Unlock].

<figure><img src="/files/GBeJBlodLdeUeWduXZOy" alt="Keystone-MetaMask-LedgerPath-17"><figcaption></figcaption></figure>

14\. MetaMask should now be successfully bound to your Keystone. Check that the “Keystone 1” account on MetaMask is the same as the account on Keystone. Now you can continue to manage your assets in this wallet by interacting with MetaMask and using your Keystone for signing purposes.

<figure><img src="/files/m6aDRs4DOUka7byKndzn" alt="Keystone-MetaMask-LedgerPath-18"><figcaption></figcaption></figure>

That’s all!

We hope this guide is useful when you decide to import an existing MetaMask Wallet/Account to a Keystone hardware wallet!

# Potential Trouble with Importing MetaMask wallet into Keystone

## I.**Important Notes**

A wallet generated by MetaMask has its recovery phrase online. This means that this recovery phrase has been connected to the network(internet).

Therefore, even if you import this recovery phrase created by MetaMask into Keystone (or any other hardware wallets) to continue managing your digital assets, this recovery phrase might already be at the risk of being attacked by hackers.

{% hint style="danger" %}
In principle, we highly recommend creating a new recovery phrase (new wallet with a 24-word seed phrase) offline on a Keystone hardware wallet and then transferring your assets from your MetaMask wallet to the new one prior to using your Keystone to interact with MetaMask. This is the safest way to protect your assets.

## II.Potential trouble sample

We have recently received feedback from some users about not being able to select certain accounts when binding their Keystone hardware wallet to MetaMask. Let’s explore and address this problem together:

(1) As you can see in the examples provided below, there are two existing accounts in the MetaMask wallet within the example shown in the picture below (“ Account 1” and “Account 2”). In this example, this wallet has already been imported into Keystone as well. The Keystone acccount0’s public key is the same as the one of MetaMask’s Account 1:

<figure><img src="/files/Kyd4mjPcW0i8gbY929lY" alt="Keystone-MetaMask-Others-1"><figcaption></figcaption></figure>

(2) When you try to bind Keystone with MetaMask under such a situation by selecting which account you wish to bind, you’ll soon find that “account 1” and “account 2”, unlike the other accounts, can not be selected as shown in the picture below：

<figure><img src="/files/9j4Q5SpS6NF3Xoig3k0N" alt="Keystone-MetaMask-Others-2"><figcaption></figcaption></figure>

(3) This happens because “account 1” and “account 2” are already bound to MetaMask.

Due to the potential scenario above, we’ve decided to write this guide to explain how to correctly import an existing MetaMask Wallet into Keystone, hoping we could help users avoid this situation.

# How to Switch ETH Path to Ledger Live / Legacy Format?

Firmware versions M-5.0 (Multi-Coin) or newer support the switching of wallet paths (ETH) to Ledger Live and Legacy formats with your Keystone device in the MetaMask / DeFi / Web3 mode.

Keystone's original default wallet path (ETH) format is BIP44 Standard so If you want to import a recovery phrase from a Ledger device (Ledger Live / Legacy), you will need to switch the wallet path to Ledger Live / Legacy formats to identify your digital assets.

This guide will show you how to switch the wallet path (ETH) to Ledger Live / Legacy formats. Let’s take a look in more detail.

## **I. Preparation**

[Firmware](https://keyst.one/firmware?locale=en) versions M-5.0 (Multi-Cion) or newer running on Keystone Essential or Pro.

{% content-ref url="/pages/-MVz-o9g8Dc-vlyVuAZj" %}

<figure><img src="/files/WWqdrIfbc4MGcwMtX6pq" alt="Keystone - different ETH path -3"><figcaption></figcaption></figure>

3\. The address format should have been changed for now. Reconnect software wallet to make this new format address binded on the software wallet.&#x20;

<figure><img src="/files/zIQshisYu3PH62PqMQQl" alt="Keystone - different ETH path -4"><figcaption></figcaption></figure>

### Important Notes

* In **ledger live** format, Keystone only supports the synchronization of the **first 10 addresses.**&#x20;
* In BIP44 Standard and ledger Legacy formats, Keystone supports the synchronization of all addresses.

# Configure EVM Chains on MetaMask

Learn how to configure EVM chains, like Binance Smart Chain, on MetaMask extension for seamless decentralized finance and blockchain applications.

Keystone with firmware versions M-5.0 provides full support for any EVM-compatible blockchains. Users can now add any EVM-compatible blockchains on Metamask and use Keystone with it.

This guide will show you how to add the Polygon (Matic Network) Network on Metamask as an example. The same method would apply for other chains. Let’s take a look in more detail.

For more information on how to use MetaMask with EVM-compatible blockchains, please visit the [MetaMask](https://metamask.io/) official website.

## **I. Preparation**

1\. [Firmware](https://keyst.one/firmware?locale=en) versions M-5.0 (Multi-Cion) or newer running on Keystone Essential or Pro.&#x20;

&#x20;  (Please read [How to Upgrade Firmware](https://support.keyst.one/getting-started/firmware-upgrading) for more details.)

2\. Install MetaMask extension with version V10.8.0 or newer.&#x20;

3\. Set up and connect MetaMask with Keystone. (Check [here](https://support.keyst.one/3rd-party-wallets/eth-and-web3-wallets-keystone/bind-metamask-with-keystone) for tutorial)

## **II. Add Polygon (Matic Network) to Metamask**

Users can choose to add Polygon (Matic Network) to MetaMask either automatically or manually.

### 1. Adding it Automatically

1\) Find the Polygon network on <https://chainlist.org>, choose the network (e.g. Polygon Mainnet) and click on \[Connect Wallet].

<figure><img src="/files/QQEpRwXY1gPlzDAgnEBs" alt="Keystone-EVM chains-1"><figcaption></figcaption></figure>

2\) Select the Account (e.g. Keystone 1), then click on \[Next] > \[Connect].

<figure><img src="/files/u44W27bRXCUZQUJn7MT4" alt="Keystone-EVM chains-2"><figcaption></figcaption></figure>

3\) Click on \[Add To MetaMask] > \[Approve] > \[Switch network].

<figure><img src="/files/qKclu0TEBHWIEOOtZ424" alt="Keystone-EVM chains-3"><figcaption></figcaption></figure>

<figure><img src="/files/NHfGST6xRgyi1R2vU1GD" alt="Keystone-EVM chains-5"><figcaption></figcaption></figure>

4\) Polygon Mainnet has now been successfully added to your MetaMask.

<figure><img src="/files/LIbU2pp5RdrFl8rDcWuc" alt="Keystone-EVM chains-6"><figcaption></figcaption></figure>

### **2.** Add it Manually&#x20;

You can add custom networks to MetaMask manually but there's probably no reason to do so unless you're a software developer. If you would still like to do so manually, please follow the instructions below:

1\) Run the MetaMask Extension and enter the MetaMask main page.

2\) Click on the Network Selection button at the top of the MetaMask Extension > \[Add Network].

<figure><img src="/files/y5tWQXg36dAtGdFipuco" alt="Keystone-EVM chains-7"><figcaption></figcaption></figure>

3\) Input the relevant Polygon details below into the blanks provided: Network Name: Polygon Mainnet. Then click \[Save]. &#x20;

* **New RPC URL**: <https://polygon-rpc.com>&#x20;
* **Chain ID**: 137&#x20;
* **Currency Symbol** (optional): MATIC&#x20;
* **Block Explorer URL** (optional): <https://explorer.matic.network/>

<figure><img src="/files/Mm4HtaKqhrAX2RxccWSS" alt="Keystone-EVM chains-8"><figcaption></figcaption></figure>

Sometimes changing the RPC URL can help during network congestion:

* [https://rpc-mainnet.matic.network
  ](<https://rpc-mainnet.matic.network&#xD;&#xA;https://rpc-mainnet.maticvigil.com&#xD;&#xA;https://rpc-mainnet.matic.quiknode.pro&#xD;&#xA;>)
* [https://rpc-mainnet.maticvigil.com

# Configuring EVM Chains on MetaMask Mobile

Learn how to configure EVM chains, like Binance Smart Chain, on MetaMask Mobile for seamless decentralized finance and blockchain applications.

The Keystone hardware Wallet supports all EVM chains compatible with MetaMask. Those EVM-compatible chains are also configurable on Metamask mobile App as well.

This guide will show you how to add the Binance Smart Chain(BSC) Mainnet Network to your Metamask mobile app. The same method is applicable for any other EVM-compatible chains.

## **I. Preparation** <a href="#id-5fbzrl90gih8" id="id-5fbzrl90gih8"></a>

1.[ Firmware](https://keyst.one/firmware?locale=en) version M-5.0 (Multi-Coin) or newer running on Keystone Essential or Pro.

2\. Connect MetaMask Mobile V5.0.0 or newer with the Keystone Hardware Wallet ([Tutorial](/3rd-party-wallets/eth-and-web3-wallets-keystone/metamask-mobile)).

***Please read***[ ***How to Upgrade Firmware***](https://support.keyst.one/getting-started/firmware-upgrading) ***for more details.***
{% endhint %}

## **II. Add EVM Chains onto MetaMask Mobile** <a href="#jruohttyn6ws" id="jruohttyn6ws"></a>

#### **1. Automatically add EVM chains** <a href="#h48006xfehdc" id="h48006xfehdc"></a>

1\) Run the MetaMask Mobile app and tap on the **Menu icon** on the top left corner and select the \[Browser] option.

2\) Type[ https://chainlist.org](https://chainlist.org/) in the URL search bar and select your desired network available on the page.

<figure><img src="/files/Grx71r6ND59XxKl1zJsB" alt="Keystone-EVM chains access-2"><figcaption></figcaption></figure>

3\) Scroll the screen down until you’ve found the network you’d like to add.

<figure><img src="/files/LqsxRCtNjQJQtClA9y5Y" alt="Keystone-EVM chains access-3"><figcaption></figcaption></figure>

4\) Select a network you’d like to add to MetaMask and tap \[Approve] to complete the addition and move onto the next step.

#### **2. Manually Configure EVM chains on MetaMask Mobile** <a href="#kymh96pa9bs7" id="kymh96pa9bs7"></a>

Adding networks manually is not recommended for normal users as it is generally used by IT developers. The instructions below explains how you can manually add networks onto the MetaMask Mobile app. For this section of the guide, we will be adding the Polygon network:

1\) Tap \[Menu Icon]> then \[Settings]

<figure><img src="/files/C6yhCPP3Ka5CcV9pIRk8" alt="Keystone-EVM chains access-6"><figcaption></figcaption></figure>

2\) Select \[Networks] and tap \[Add Network]

<figure><img src="/files/FCRMmUJxsPBGI1dVBXyf" alt="Keystone-EVM chains access-7"><figcaption></figcaption></figure>

3\) Input the necessary Polygon network details below into the blanks provided. Then tap \[Save].

* **Network Name:** Polygon Mainnet
* **New RPC URL**:[ https://polygon-rpc.com](https://polygon-rpc.com/)
* **Chain ID**: 137
* **Currency Symbol** (optional): MATIC
* **Block Explorer URL** (optional):[ https://explorer.matic.network/](https://explorer.matic.network/)

<figure><img src="/files/KpHIEGn5yx5EKNdQmLiZ" alt="Keystone-EVM chains access-8"><figcaption></figcaption></figure>

Sometimes, changing the RPC URL can help with transactions during network congestion:

* [https://rpc-mainnet.matic.network](https://rpc-mainnet.matic.networkhttps/rpc-mainnet.maticvigil.comhttps://rpc-mainnet.matic.quiknode.pro)
* [https://rpc-mainnet.maticvigil.com](https://rpc-mainnet.matic.networkhttps/rpc-mainnet.maticvigil.comhttps://rpc-mainnet.matic.quiknode.pro)
* [https://rpc-mainnet.matic.quiknode.pr](https://rpc-mainnet.matic.networkhttps/rpc-mainnet.maticvigil.comhttps://rpc-mainnet.matic.quiknode.pro)

4\) You have now connected to the Polygon Mainnet with your Metamask Wallet!
