Just over a month ago we announced the released of Anchor for Desktop and have since been working with developers to integrate it into as many projects and platforms as possible. In the same announcement post we also offered a glimpse of the vision we have for EOSIO blockchain interactions using the EOSIO Signing Request protocol.
Today we’re excited to announce the next piece of this puzzle by bringing the Anchor experience to mobile devices.
The portable version of Anchor isn’t your typical wallet, it’s been developed from the ground up to act as an authenticator first. This means it was designed as a utility app and serves as a portable trusted device to use with external media and applications (aka “dApps”).
There are two primary ways that Anchor can be used to interact with EOSIO blockchains:
Fun fact:* This blog post was created by an EOS application called Decentium. We signed in using the Anchor mobile app, wrote this post, and then approved the transaction to publish this post on the EOS blockchain using our mobile device.*
These flexible methods allow for new and exciting ways to leverage EOSIO for both businesses and developers, while working to reduce friction that typically hinder adoption by end users.
Interested in trying it?
If you have an iOS device running version 13+, we’d invite you to join our TestFlight beta program and try it today. Simply click the following link from your mobile device to get started:
The current build of the beta (16) supports the following EOSIO networks:
NOTICE TO ALL TESTERS: This is a beta product, things can and will go wrong. We’d recommend you either use an account of little/no value or a testnet account. Also make sure you have backups of your keys stored externally in safe location, as breaking changes during the beta may cause data loss within the application.
As a note to the Android users out there - hang tight, we’re working on bringing Anchor to your platform as well. The initial groundwork is being laid to bring the same experience over from iOS.
With Anchor for mobile, we aimed to streamline the account import process as much as possible. The entire import process is shown in the short animation below.
When you tap to import and account, you’ll be prompted for your private key. You can either type it, paste it, or scan a QR code containing the private key.
Anchor will then scan for any existing accounts on all supported EOSIO networks and allow you to select which account to import.
Once an account is selected the final optional step allows you to associate a pin to the account and/or use the biometrics of the device to restrict access.
You’re now ready to authenticate with any compatible EOSIO application and use Anchor to sign transactions! If you have more than one account on more than one network, simply repeat this process to load any additional accounts.
Note: The initial release of Anchor for mobile will only support the import of existing accounts and will not have account creation. Creating accounts is a feature we are working to bring to both mobile and desktop, which you can expect updates on in the future.
If so, you can easily import an account into the mobile wallet from your desktop wallet using the new QR Code feature we have added in Anchor (1.0.3).
To do this, go into the “Manage Wallets” section of the desktop application, and with the wallet unlocked, click the “View Wallet” option on the account you’d like to import. There is a new button in the private key area you can use to display a QR Code, which can be scanned by Anchor mobile import process to immediately import that private key and get started!
The experience for an Anchor sign-in can work in two distinct ways:
Using Anchor mobile on the same device
If you visit a website that’s integrated Anchor for desktop already, the same processes work if you visit using your mobile device. Simply use the app or website, go through their sign in process, and when the Anchor prompt appears click the “Open Anchor App” button right below the QR Code. Your device will swap to the Anchor mobile app and ask you to prove your identity.
When this is complete you’ll be redirected back and logged into the app/website. From there on out you’ll be able to interact with that application using your EOSIO account. Each time a request is made you’ll be able to approve it from your mobile wallet and securely sign transactions.
Using Anchor mobile with another device
If you’ve used Anchor for desktop already, you probably noticed the QR Code that’s displayed when you first signed in to an external application. That QR Code is what you can use to link an application to your mobile wallet. Simply scan the QR Code with your mobile wallet and you’ll be prompted to prove your identity and setup a session for future use.
Once completed you’ll be able to use the application on the secondary device, while all requests will then be routed to the mobile device for approval.
For the iOS test version we are announcing today - we built the entire experience using the native UI kit. This means the app supports both light and dark modes, can be used on an iPhone or iPad, and also supports landscape mode for iPad users who use their tablet as more of a miniature laptop.
Our goal is to keep things as simple as possible while also maintaining enough flexibility so Anchor fits every use case.
Mobile security isn’t perfect (nothing is), but we use the latest technologies to create the most secure mobile experience possible. Anchor on your mobile device uses the secure enclave components of the device for key storage, which makes it incredibly hard for attackers even with physical access to your device to compromise your account.
Both the EOSIO Signing Request protocol and Anchor are still relatively new, so the applications compatible with it are still somewhat limited. Here’s a short alphabetical list of a few applications you can help test it with today, using either the desktop or mobile wallet:
More and more applications supporting Anchor will be coming online soon.
If you’re a developer and are interested in integrating Anchor with your application, feel free to reach out to us. We’re more than happy to help guide and help you during the integration process. You’ll only have to integrate once both desktop and mobile, since they use the same protocol!
