Envoy version 1.6.0 is now live!

We’re excited to announce that the latest version of Envoy1.6.0 – is now published on all your favorite mobile platforms! To download it, simply visit our download page or check for updates on your platform of choice.

Please note that there can be a significant lag from publishing to general availability due to Apple App Store and Google Play Store review policies and delays.

What’s changed

We’ve focused Envoy 1.6.0 on a vital new feature for Bitcoin’s volatile fee market — replace-by-fee (otherwise known as “RBF”). RBF allows you to easily boost the fee on a transaction you’ve sent that’s stuck surfing the mempool, or even cancel an in-flight transaction and send it back to yourself. Just tap on any transaction that is unconfirmed and quickly Boost or Cancel it in Envoy.

We’ve also brought a complete redesign of address and amount displays to Envoy, making it drastically easier and more intuitive to view amounts (in sats or BTC, as always!) or verify addresses. A special thanks to the fantastic Bitcoin Design initiative for spearheading the concept here! Oh, and don’t sleep on custom device names for Passports paired to Envoy, and the new Catalan translation 👀

For more details on each of the changes, keep reading below!

New Features

  • Full “replace-by-fee (RBF)” control is here!
    • If you’ve ever sent some Bitcoin only to have them get stuck in the mempool due to a crazy fee market, this one is for you!Now you can simply tap “⏩ Boost” when viewing a pending transaction’s details to get your transaction back to the top of the queue.Sent a transaction but realized it was a mistake? You can also tap “Cancel” and send the funds back to yourself using RBF as well 😌
  • When you set a custom name for your Passport, now that name will show up automatically in the Devices tab on Envoy.
    • Have multiple Passports in the house? Now you can easily tell them apart in Envoy using custom names!
    • Any name on Passport will now automatically be synced to Envoy when pairing for the first time.
      • Note that existing Passport names won’t be updated unless they are deleted first, but we’ll be improving that in Envoy v1.7.0!
  • Envoy translated to Catalan thanks to our friends over at @bcnbitcoinonly! Special thanks to @insatwetrust, in particular!!


  • Improved Tor performance on iOS (and some Android vendors), especially when it comes to getting fiat exchange rates.
  • Improved testnet reliability via new testnet Fulcrum infrastructure.
  • Available balance now shows fiat value in addition to Bitcoin, if fiat is enabled.
  • Improved the way fiat is displayed in the Transaction Details screen.
  • Updated OpenSSL libraries and removed some unnecessary dependencies.
  • Updated Arti (the Rust-native Tor library) in our library to the latest version, v1.1.12.
  • Improved tap targets across the board to make it that much easier to get to what you want in Envoy.
  • Tapping on the Accounts tab when inside an account will take you back to the main Accounts view.
  • When Fiat values are loading they will now display a loading bar instead of a 0.
  • We’ve taken a fine-toothed comb to the UI in Envoy and made a number of improvements across the board. Better UI, better UX, better Bitcoin experience.
  • Improved Spanish translations.

Bug Fixes

  • Fixed a bug where Envoy would slow down if a custom Electrum server was unreachable for a long period of time.
  • Fixed a rare bug where sometimes the change address would be displayed as the destination address.
  • Fixed a bug where in some iOS instances selecting Custom fee would result in a crash.
    • Thank you @Fredodido56 for the report!
  • Fixed a bug where the German locale could randomly show commas and dots while typing a number in.
    • Kudos to Mike from our TG community for the report!
  • Fixed an issue where iPhone 8 users wouldn’t be able to tag coins.
  • Fixed an issue with displaying a 24-word seed when manually imported.
  • Fixed some minor issues where under certain circumstances fiat values wouldn’t display correctly.
  • Fixed a visual bug where after deleting a hot wallet and the backup, the Accounts view’s title would be displayed incorrectly.
  • Fixed some text strings wrapping when they shouldn’t have.
  • Fixed a minor bug where sometimes the user would be asked twice about adding a Note to a transaction when signing with Passport.
  • Fixed a minor bug where the small coin exclusion alert was triggered when it shouldn’t have been.
  • Fixed a minor issue where under specific circumstances a user was able to add an infinitely long tag name that broke the UI.
  • Fixed an edge case where the user would be able to attempt to build a transaction with negative fees.
  • Fixed an issue where Envoy could freeze if a user attempted to export an abnormal amount of logs.
    • As always, we take your privacy seriously! Envoy does not send logs to Foundation (and has no ability to do so), so this only applies to users who manually tried to export logs to share with us for a bug report.
  • Fixed an issue where Envoy could freeze if the change amount was too big when setting a custom fee.

Passport version 2.3.0 is now live!

We’re excited to announce that the latest version of Passport firmware – 2.3.0 – is now live! To download it, simply initiate the update from Envoy to be guided through the process.


We’re beyond thrilled to be able to release Passport firmware v2.3.0, including full Taproot support, revamped passphrase behavior, an all-new address explorer, master seed SeedQR export, 12-word seed phrase support, 12th/24th word generation for advanced users, and native OP_RETURN message viewing and signing.

This release is one of our largest to date and includes a massive amount of new features, improvements, and bug fixes.

For more details on each of the changes, keep reading below!


  • Say hello to full Taproot support in Passport 🥕
    • Passport now has full support for sending and receiving using Taproot, making the combination of Envoy and Passport a powerful way to leverage the latest and greatest tech that Bitcoin has to offer.
    • Note: existing Passport users will need to re-pair Passport to add Taproot-specific accounts (Envoy will automatically prompt you to do this the first time you enable Taproot).
    • Envoy must be on v1.5.0 or greater to use Taproot in Envoy directly.
  • Passport now has full support for verifying and displaying OP_RETURN messages directly on-screen.
  • Account and multisig configuration displays have been reworked to make them contextual to the currently active wallet.
    • Previously additional accounts were displayed irrespective of there being a passphrase applied or not.
    • Now, you’ll only see the account(s) specific to the currently active wallet. For example, if you’ve only ever used account #2 named 'Savings' under the passphrase 123abc, then you’ll only see that account when the passphrase 123abc is active. The same also applies to multisig configurations.
  • You can now export Passport’s master seed phrase via SeedQR, if desired.
    • Please note that this contains your seed phrase in a QR format, and so should be treated just as carefully as your seed phrase itself! Don’t scan it with your camera app, save it in an image, etc.
    • Both Compact and standard SeedQR are supported.
    • You can find the SeedQR export when viewing your seed phrase by using the left-select button to open the SeedQR export menu.
  • We’ve added a brand new address explorer, allowing you to browse receive addresses directly on Passport and even display them as QR codes!
    • Note that since Passport is an air-gapped wallet, it cannot know which addresses have or have not been used, or what your balance is.
    • You can easily access the new address explorer under the “Manage Account” section of each account.
  • Passport now allows the creation of 12 word seed phrases, and defaults to 12 word seed phrases during onboarding.
    • Users can still choose 24 word seed phrases if desired.

    • We’ve gone in-depth in a past blog post on why, but 12 word seed phrases are more secure than necessary and easier to backup and recover than 24 word seed phrases. If you’re curious for more background, read our blog post:
  • Advanced users can now generate 11 or 23 words offline, import into Passport, and Passport will automatically calculate the checksum 12th or 24th word when importing the new seed.
    • Note that if a seed is generated outside of Passport, we cannot guarantee it was done securely! There have been many cases recently of users improperly generating a seed phrase (i.e. not providing enough randomness/entropy) and having funds stolen as soon as they send them to the new seed.
    • We always recommend allowing Passport to generate new seeds for you unless you are an advanced user that understands the risks with manual seed generation via dice rolls etc.
  • You can now set a custom name for your Passport!
    • This name will be displayed on boot, making it easier to distinguish between your various Passport devices.
    • This new setting can be found under Device > Device Name in settings.
  • You can now check the exact percentage of battery Passport has in the settings under Device > Battery.


  • We’ve improved address display based on the Bitcoin Design guidelines, making it easier than ever to verify addresses on Passport!
  • Verifying addresses on Passport is now significantly faster.
  • Passport now only prompts a single/multisig wallet type choice when verifying addresses if there is a multisig config imported for the active wallet fingerprint.
  • Users can now optionally display the seed words on-screen when first setting up Passport and using encrypted backups.
  • Improved how headers are displayed when creating or importing seeds to better reflect which step of the process a user is on.
  • Added a prompt to users setting up Passport to ensure they are in a private or secure place before carrying out the setup process.
  • Removed an unnecessary prompt to select or delete firmware when going through the firmware update flow.
  • Removed unnecessary imports in the firmware compilation process, optimizing Passport firmware size.
  • Backups can now be restored from anywhere on a microSD card, not just from the “proper” backups folder.
  • Browsing files on microSD no longer has a 20 file limit.
  • Improved minor error message dialogues.
  • Auto-shutdown has been lengthened for the onboarding process to avoid accidental shutdowns during onboarding.
  • Improved the success icon when verifying addresses.
  • Verifying reproducible builds of Passport firmware is now possible without granting Docker root permissions.
  • Wasabi Wallet has been removed from the list of export options.


  • Fixed an incorrect warning dialogue when backing out of a manual encrypted backup.
  • Key Manager seed export no longer displays a setup screen that was there by mistake.
  • Fixed an issue where you couldn’t go back in the Predictive text explainers.
  • Fixed an issue where pressing back on SeedQR recovery screens would throw an error.
  • Fixed an issue where using the # character in an account name would break account name display.
  • Fixed a minor bottom menu selection display bug after exporting to SeedQR
  • Fixed a minor visual issue where the header would start scrolling in FE because it was too long.
  • Security words can only be enabled if you input the pin again correctly now.
    • Thanks to @backtopyramidone on Github for the report!
  • Improved the setup flow after resetting Passport to prevent a potential bug.

Passport version 2.2.0 is now live!

We’re excited to announce that the latest version of Passport firmware – 2.2.0 – is now live! To download it, simply initiate the update from Envoy to be guided through the process.


With this version of Passport’s firmware we’ve added the ability to seamlessly switch back and forth between signing via QR and microSD, added the ability to restore from SeedQR, improved the user interface on Founder’s Edition, and added many quality of life improvements across the board. With the number of new features we included in 2.1.0, we took this release to focus on refining our unified firmware between Founder’s Edition and Batch 2, as well as paving the way for full Taproot support in 2.3.0.

For more details on each of the changes, keep reading below!


  • Automatically detect when a transaction being signed via QR is very large and prompt the user with the option to sign via microSD instead.
    • When a transaction is very large signing via QR codes can take quite a long time. This change makes it much easier for users to switch to signing via microSD before going through the hassle of trying to sign an excessively large QR code.
  • You can now write a signed transaction out to microSD directly from the animated QR screen on Passport.
    • Changed your mind and want to use microSD for that transaction you just signed? Now you can do so all from the same screen without having to go through the process of signing again.
  • You can now import a SeedQR directly into Passport when restoring from seed.
    • Easily import a SeedQR from an existing wallet or restore from a SeedQR backup of Passport with a simple QR scan.


  • Further improved signing of abnormally large transactions via both QR code and microSD.
  • Added an automatic encrypted microSD backup step when restoring Passport from a seed phrase.
  • Improved the spacing and alignment of text throughout the menu UI on Founder’s Edition to better account for the slightly different screen sizes.
  • Implemented secp256k1 support from rust-bitcoin, a requirement for full Taproot receive support in a future update.
  • We now create directories automatically on the microSD card as needed for storing partially-signed Bitcoin transactions (PSBTs), multisig configs, wallet configs, health checks, and Key manager.
    • This makes managing files much easier, especially when viewing the contents of your microSD card on a computer.
  • Passport now uses a 3-digit code for sorting backup files, ensuring that backups are easier to distinguish and sort.
    • Backups are now also sorted in reverse order, so you’ll always find your latest backup at the top when restoring or viewing existing backups!
  • Added additional context when setting a passphrase to ensure users understand that all passphrases are valid, and that Passport will clear passphrases upon shutdown.
  • Initial address verification for new accounts is now much faster.
  • Optimized fonts to free up some space in firmware.
  • Improved the Foundation icon when setting up a new Passport Founder’s Edition device.
  • Improved special character selection.
  • Upgraded to the latest version of foundation-rs, our open-source Rust library.
  • Removed unnecessary USB files, correcting a minor licensing display issue and simplifying compilation.
  • Improved copy and behavior of hiding and showing hidden keys in Key Manager.
  • Improved the behavior of the passphrase application flow when a user incorrectly enters a passphrase and notices the fingerprint does not match.
  • Improved copy on the account details screen regarding the derivation path.
  • Improved the way top icons are displayed on Founder’s Edition.
  • Improved battery level detection and display on Founder’s Edition.


  • Fixed a rare bug that wouldn’t properly display the message after a device is bricked after 21 failed PIN attempts.
  • Passport now properly displays an error when an unusable QR code is scanned that the user can close.
  • Passport now properly resumes saving a file if a microSD card is inserted at the “Missing microSD card” screen.
  • Fixed a display issue when canceling a transaction before signing.
  • Fixed a rare bug where big transactions would occasionally prevent Founder’s Edition from displaying the signed QR code transaction.
  • Fixed a minor display issue with specific, long-form error messages.
  • Fixed a minor issue when exporting to Sparrow under rare circumstances.

Envoy version 1.5.1 is now live!

We’re excited to announce that the latest version of Envoy1.5.1 – is now published on all your favorite mobile platforms! To download it, simply visit our download page or check for updates on your platform of choice.

Please note that there can be a significant lag from publishing to general availability due to Apple App Store and Google Play Store review policies and delays.

What’s changed

Note: v1.5.1 is a bug-fix release that resolves an issue updating firmware via Envoy on iOS. We’ve replicated the release notes here from 1.5.0 with the additional bug fix.

With this release of Envoy, we’ve focused on bringing you fully-featured support for Taproot! This not only expands the use-cases and access for Envoy as a mobile wallet, but it also paves the way for full Taproot support to be added to Passport in the upcoming v2.3.0 firmware. We’ve also included a proper Spanish translation to Envoy, and many quality of life improvements and bug fixes.

For more details on each of the changes, keep reading below!

New Features

  • Envoy now has full Taproot ???? support, allowing you to easily send and receive with the latest and greatest features in Bitcoin!
    • For those who want to use Taproot, simply enable support from the settings under the “Advanced” drop-down and a new Taproot-specific account will be created for you.
    • This also paves the way for full Taproot support in Passport, coming in firmware v2.3.0 very soon!
  • Envoy now has a Spanish translation available to all of our Spanish-speaking users!


  • Envoy now allows users to select a preferred language in settings on iOS and Android.
  • Upgrade Flutter to the latest stable release, v3.16.1.
  • Envoy now automatically excludes coins that are too low of a value to spend in the current high-fee environment.
    • We’ve noticed that in the current fee environment, a native behavior of BDK that is designed to protect you from wasting sats could get a bit confusing. If you have coins that are relatively low value, it’s possible that they could cost more to spend than the value of the coin, meaning spending them would just be burning precious satoshis.
    • We still leverage the BDK default to help protect you from losing satoshis sending coins that are too low of value, but now we give you a clear warning when this would happen via a shiny new modal.
  • You can now hide amounts on an account while in the detailed account view.
  • Improved how the bottom sheet shows amounts when using coin control when minimized.
  • Users who have previously used Magic Backups and then manually restore the same seed now get the option to restore their previous Magic Backup or simply use a manual wallet.
  • Improved how selecting coins works when switching views.
  • Added a warning when a user manually selects coins and then changes the fee on the transaction review screen, as it can cause Envoy to automatically re-select coins for the user.
  • Updated our Tor library to the latest version of Arti, v1.1.11.

Bug Fixes

  • Fixed an issue unselecting an entire tag in coin control if some coins in that tag are locked.
  • Fixed a minor display issue when deleting a mobile wallet.
  • Fix an issue with units displayed on the send screen showing sats even when denominated in BTC.
  • Fixed an issue where redeeming an Azteco voucher could show duplicate entries in the activity screen.
  • Corrected the informational text on the unsigned PSBT screen.
  • Fixed an issue where the firmware update button would be slightly off-center.
  • Fixed a minor padding issue on the tag details card.
  • Fixed a rare issue that could cause a blank screen when pairing an existing Passport account.
  • Fixed an issue where an address could display incorrectly in the transaction details screen when receiving multiple outputs in a single transaction.
  • Fixed a display issue where excessively long device names could break the version pill on the devices tab.
  • Fixed an account renaming issue.
  • Fixed various minor display issues.

What’s changed

In this version of Envoy we’ve implemented intuitive and easy-to-use coin control, a new Activity Center and Privacy Shield, a redesigned Learn tab, broad user experience and user interface improvements, and squashed bugs across the board.

We’re especially excited about our implementation of coin control in Envoy, as there has been a lack of intuitive coin control on mobile for Bitcoin users in the past, even though coin control is vital for giving you control over your privacy. We’ve spent countless hours building coin control in Envoy from the ground up to be as easy to use, as powerful, and as privacy-preserving as possible. Coin control isn’t just for technical users anymore.

  • Made it easier to use Envoy purely as a Passport companion app for those who don’t want Envoy as a mobile wallet.
    • It’s now easier to add additional Passport accounts without accidentally triggering the mobile wallet setup flow.
  • Improved screens across iOS, specifically those around pairing with Passport and downloading firmware.
  • Added the ability for Envoy to use the system locale to better display units and times throughout the app.
  • Added a shiny new animation to the manual mobile wallet setup flow.

Envoy 1.4 – Say Hello to Coin Control

With the release of Envoy version 1.4 today, we’ve taken the next big leap forwards in our goal with Envoy — to bring the best of Bitcoin to you, simplified. Since the release of Envoy’s full mobile wallet functionality with Magic Backup, we’ve been working tirelessly to bring you the next phase focused on giving you full control over your Bitcoin. Say hello to the most intuitive and approachable coin control to date.

Coin Control Made Easy

Taking control of your money has been a part of our mission from day one, and the ability to control exactly how you spend your bitcoin through Envoy is a key part of that. In this release of Envoy we’ve spent countless hours taking the concept of coin control that has existed in other Bitcoin wallets back to the drawing board, as coin control should be within reach of everyone, not just “techy” Bitcoiners. We think coin control should be something even grandma can use.

The concept of coin control can often be a foreign one to new Bitcoiners, but quite simply it’s a tool that allows you to choose what coins get spent in each transaction. The standard functionality of a wallet is to use a coin-selection algorithm to intelligently select the best coins to spend when you send bitcoin, but without some form of coin control there is no way for the algorithm to know what history each coin carries with it. When you combine coins with different histories, you reveal information about your financial activity you may not be intending to share!

When you use coin control, you can tag coins and add notes to transactions as you use Envoy, allowing you to spend only the coins which you want to each time you spend your bitcoin. Don’t want to reveal how much you get paid to your grocer? Only pay him using coins from your previous visits to the grocery store. Tired of your barista seeing how much you paid for dinner last night? Only pay him using coins you just got peer-to-peer. Coin control gives you total control over what information you choose to reveal each time you use Bitcoin — the very definition of privacy.

Using coin control on Envoy is just a tap away behind the new “Tags” icon inside of each account, where you can easily select to spend from an entire tag or get into the weeds and select individual coins to spend. You can keep things as simple as you want or get as granular as you want — you’re in control now. And if the concept of coin control seems like too much for you today, you can simply never touch it and still benefit from a smart coin-selection algorithm in the background that does its best to reduce fees while preserving your privacy.

All of this functionality gets added on top of the 60 second onboarding that Envoy brings via Magic Backups, the seamless integration with Passport, and the fully customizable privacy settings across the board. It’s time you experienced Bitcoin, simplified by downloading Envoy today.

If you want to deep dive into how you can use coin control we’ve got you covered with our new docs on the topic: Tags, Notes + Coin Control | Foundation Docs

Redesigned Learn Center

We have a deep passion for user education and empowerment, and want to make the output of that passion more accessible through Envoy. When you have questions about how Envoy or Passport works, want to learn more about Bitcoin, or simply want to pass the time with the sound of BitcoinQnA’s voice in the background, we’ve got you covered. We’ve started from scratch and improved every aspect of the Learn center, starting with a drastically improved video player and a new video host. Videos are faster to load, easier to control, and are now automatically marked as watched afterwards.

We’ve also added full support for reading our blog posts directly in Envoy without ever leaving the app or opening your browser. Blog posts also get marked as read immediately after viewing them, making it simple to keep up with the latest in Foundation announcements and education. In addition, we’ve revamped our FAQ section at the bottom and updated it with all of the recent changes in Envoy and Passport.

Privacy Shield Joins the Toolbar

We’ve always held preserving user privacy as one of our chief values at Foundation, and that starts with the options available to our Passport and Envoy users. With this version of Envoy, we’re taking things a step further and improving the visibility and usability of all of those privacy settings in Envoy with a new standalone section we’re calling the “Privacy Shield.” Quickly connect to your own Bitcoin full node, switch back to Foundation’s, use Tor for improved privacy, or turn Tor off for better performance when necessary.

Everything you need to know about preserving your privacy while using Envoy can be found in our documentation: Privacy | Foundation Docs

Activity Center, Reborn

In addition to launching coin control and revamping our privacy settings, we’ve taken the time to overhaul the activity center in Envoy and give it a new home in the toolbar. Everything you need to keep up with your Bitcoin activity, Passport firmware updates, and more can be found in the Activity Center now. We plan on expanding this in the near future to encompass more things as well, so keep an eye out for future Envoy updates!

Envoy version 1.3.0 is now live!

We’re excited to announce that the latest version of Envoy1.3.0 – is now published on all your favorite mobile platforms! To download it, simply visit our download page or check for updates on your platform of choice.

Please note that there can be a lag from publishing to general availability due to Apple App Store and Google Play Store review policies and delays.

What’s changed

In this version of Envoy we’ve implemented the ability to redeem vouchers with a single QR scan in Envoy directly to your mobile wallet, added the ability to cycle through units by tapping on amounts, the ability to update Founder’s Edition devices directly from Envoy, and focused heavily on refining user experience for Envoy mobile wallet users.

With the release of our last major version of Envoy, we transformed Envoy into a standalone Bitcoin mobile wallet with powerful account management and privacy features in addition to its role as Passport companion app. With that came many new screens and features, so we’ve taken this release to focus on iterating and bringing many bug fixes and quality of life improvements for all our fantastic Envoy users.

As you may have noticed, we’ve skipped v1.2.0 and jumped straight to v1.3.0 as we realized we had too many important changes to be made during the beta period for v1.2.0. As a result this changelog includes all major changes introduced in v1.2.0 as well, so it’s extra long and extra exciting.

For more details on each of the changes, keep reading below!

New Features

  • You can now redeem vouchers directly in Envoy with just a few taps!

Announcing Envoy Wallet: Bitcoin Simplified

We’re thrilled to announce a groundbreaking release of Envoy, our mobile companion app for Passport. This new update transforms Envoy into a standalone Bitcoin mobile wallet with powerful account management and privacy features.

Envoy makes financial sovereignty more accessible than ever before and radically lowers the barriers to Bitcoin self custody.

Notably, Envoy Magic Backups take the pain and worry out of setting up and backing up a mobile wallet, allowing you to get up and running in 60 seconds and restore your wallet anytime, on any device, in just three taps. It’s time you experienced Bitcoin, simplified.

Read below to learn more, or dive right in and download Envoy now!


With mobile wallet support in Envoy, the combination of Envoy + Passport empowers you to store your wealth in an ultra secure, intuitive hardware wallet while also spending Bitcoin on the go in just a few taps. Move funds back and forth between Envoy and Passport, make airgapped transactions, and access your spending and saving balances from anywhere – all in a single app!

Not a Passport owner? This update introduces full Bitcoin wallet functionality on your iOS or Android phone. Use Envoy to store and spend your Bitcoin with strong security, privacy via Tor, and a streamlined setup experience.

We are excited to bring our best-in-class design, intuitive and approachable user experience, and peace of mind to smartphone users across the globe – no Passport required.


In Bitcoin, the term “mobile wallet” refers to any wallet that keeps your keys on an internet-connected smartphone for easier spending and receiving of funds. While you should not keep your life savings in a mobile wallet, it provides easier access to a small amount of Bitcoin for spending, withdrawing from an exchange, and onboarding new users.

Envoy has traditionally been a “watch-only wallet” that connects to Passport, allowing you to view your balance and create transactions, but providing limited functionality when you are away from your hardware wallet. Now you can enjoy Envoy as a full-featured Bitcoin wallet on the go.


Envoy introduces a new seed-less onboarding experience called Magic Backups. While Envoy users can of course manually handle seed words if desired, we aimed to engineer a solution that enables 60-second onboarding and automatic encrypted backups of Envoy’s private key and application data (such as settings and labels), with a full restore taking just three taps.

Additionally, we wanted to ensure that Envoy does this without collecting any user data – no email address, no passwords, no IP address (when Tor is enabled) – no friction!

We expect Envoy Magic Backups will lead to a massive increase in self custody, with easier onboarding than you’d find at any Bitcoin exchange or custodian.


  1. Envoy generates a seed and stores it on your phone’s secure element.
  2. Since most users have iCloud Keychain or Android Auto Backup enabled, the seed is automatically synced to your other iOS or Android devices – fully end-to-end encrypted, without needing to give Envoy permission to access your iCloud or Google account. This encryption means that only you can access this data, not even Apple or Google.
    • Learn more about iCloud Keychain.
      • “iCloud protects your information with end-to-end encryption, which provides the highest level of data security. Your data is protected with a key that’s made from information unique to your device, and combined with your device passcode, which only you know. No one else can access or read this data, either in transit or storage.”
    • Learn more about Android Auto Backup.
      • “Android preserves app data by uploading it to the user’s Google Drive—where it’s protected by the user’s Google account credentials. The backup is end-to-end encrypted on devices running Android 9 or higher using the device’s pin, pattern, or password.”
  3. Envoy then creates a backup file containing your app settings, account labels, and other non-sensitive app data, so that Envoy can be restored to its exact previous state. This folder is end-to-end encrypted with your seed so that Foundation can never see the contents. We call this the Envoy Backup.
  4. The fully encrypted Envoy Backup is uploaded to Foundation’s servers, alongside a hash of the seed (a cryptographic representation of the seed that proves your knowledge of the seed, not the seed itself!) so that we can ensure no one else can attempt to download your backup without proving knowledge of your seed phrase.
  5. There is no Foundation user account, no email, no password – all you need is access to your iCloud or Google account.


If you lose your phone or delete the Envoy app, restoring your wallet takes only a few seconds with Magic Backups.

  1. Envoy checks the secure element on your phone and looks for the seed.
    • If it discovers a seed on the secure element, Envoy hashes the seed and sends the hash to our server.
      • This merely proves your knowledge of the seed and does not reveal your seed to Foundation in any way!
    • If it does not discover a seed, it accesses the encrypted backup from iCloud Keychain or Android Auto Backup and restores the seed to the secure element. Then Envoy hashes the seed and sends the hash to our server.
  2. Envoy then downloads the encrypted Envoy Backup from our servers.
  3. Envoy uses the seed to decrypt the Envoy Backup file locally (on your phone!) and restores all user settings, account labels, and other app data – so it’s like you never left.


We’ve also added the following features and improvements in this release:

  • Biometric/PIN authentication. Now you can protect your mobile wallet or Passport balances from prying eyes
  • Ability to swipe on accounts to hide balances while you’re on the go. For example, you can display your mobile wallet balance but hide your hardware wallet balance.


We’ve released this new version of Envoy to all major platforms, so you can choose the method that suits you best below:

  1. If you’re on iOS, you can install Envoy from the App Store using the following link:
  2. For those on Android, you can either find Envoy in the Play Store, install via F-Droid, or download the app directly from Github (Envoy is fully open source!):
    • Play Store
    • F-Droid
    • GitHub
      • Download the APK titled “envoy-apk-1.1.3.apk” directly from the above link and install
      • As this APK is signed with our own keys instead of Google’s keys via the Play Store, if you’re using the Play Store version you’ll have to uninstall Envoy first before installing the public beta


As you use Envoy as a mobile wallet, we’d love to hear from you – every issue, bug, or favorite feature! There are three main places you can go to give us feedback or get help with Envoy:

  1. We have a standalone Telegram channel for our community that you can join and give feedback or get support
  2. You can email us
  3. You can direct message us on Twitter


The release of Envoy as a mobile wallet paves the way for a range of roadmap items we’ve been planning for some time, and we can’t wait to build on this strong foundation of simplified Bitcoin usage. Next you’ll be able to jump in the ???? with thousands of other Bitcoiners, become a ????, or ⚡ your way to a cup of coffee — all within Envoy!

We’re excited to release the next piece of your financial sovereignty toolkit to the masses and onboard a wave of Bitcoiners to self-custody, privacy, and financial sovereignty sat by sat.

Now back to building.
