Customizing Jaxx: How to Manage Tokens and Currencies

In line with Jaxx’s mission to unify the blockchain experience, we have integrated multiple tokens into our wallet over the past few months and continue to explore opportunities with other tokens. At this point, you can manage Bitcoin, Ether, Ethereum Classic, DASH, Litecoin and Augur’s REP in Jaxx, and easily convert them right in the wallet using ShapeShift.

 

While offering the option to hold several different tokens, we take into account that some users might only transact in one token or a select few. Also, given our users are based in different countries across the globe, we provide a series of fiat currencies. With our users in mind, we’ve introduced a feature that allows users to select which tokens and currencies are displayed by default and how to hide the rest.

 

Demo on Customizing Jaxx

 

In the video below, Annie from Jaxx will show you how to customize your Jaxx wallet so that you can add and sort the tokens and currencies that you want to see.

 

Her Jaxx wallet on iOS initially supports Bitcoin and Ethereum tokens only, in Canadian and US currencies. By going to “wallets” nested in the hamburger menu on the top right hand corner, you can add a few more or all of the tokens that Jaxx offers to the main interface, and display more or all of the currencies. You can also customize the order that tokens and currencies appear in by dragging and dropping them.

 

If you accidentally unchecked a token you have funds in, don’t worry. When a token is hidden, you won’t lose any of your funds; they will be sitting there until you re-activate it.

 

In any case, don’t forget to back up your wallet and secure your 12-word mnemonic phrase. Only get your Jaxx wallet from Jaxx.io and trusted stores. 

 

 

The Fintech and Blockchain World Expo has been postponed

The following is an important announcement concerning the forthcoming Fintech and Blockchain World Expo.

 

After consulting with several of our major event partners, as well as conducting a thorough internal review, we have decided to postpone the Expo to a future date yet to be determined.

 

The principal reason for the postponement is the number of conflicting, similarly themed events taking place on and around the same time as the Expo. Some of our major event partners felt that postponing the Expo to a less crowded time period would result in a greatly improved experience for all Expo attendees, participants, and collaborators.

 

Planning and executing an event like the Expo requires an intense amount of work and internal resources, and one of the other reasons we’re postponing the event is to refocus some of our efforts on projects that have been left underserved in the run-up to the Expo. We think we can better serve the blockchain community by redoubling our efforts on these projects for the time being.

 

Existing ticketholders have been offered a refund.

 

For any questions or concerns regarding the Expo’s postponement, please contact Events Coordinator Matthew Brown at matthew@decentral.ca.

Jaxx 1.0.5 released with adjustable BTC fee for added flexibility

If you’ve been paying attention to Bitcoin network activity over the last couple of days, you’ve undoubtedly noticed that it’s spiked to levels not seen in over two years. That’s great news for BTC holders, but a pain for wallet users who have seen their transactions take longer and longer. With the release of Jaxx 1.0.5, this will no longer be an issue.

 

Jaxx 1.0.5 adds the option to select a “Slow,” “Average,” or “Fast” fee level, all of which are dynamically adjusted based on the level of current network activity. Now, users who are unconcerned with speed don’t have to face heftier transaction fees, while power users can ensure that their transactions will be accepted by the network very quickly.

 

What we have in place is not a perfect solution, but we felt it was important to update our current options so that current Jaxx users won’t be faced with interminable wait times for BTC transactions. In future, we will also be adding Custom fee option, allowing users to specify their fee well above or below even Jaxx’s recommendations. 

 

Previously, we had a floating fee rate based on the current transaction filesize, but this new solution is more effective for handling the current state of the Bitcoin network.

 

As per usual, iOS users will have to wait a little longer for Jaxx 1.0.5 due to Apple’s length app review process. If there was anything we could do about it, we would!

Jaxx Dev Day: v1.0.4 is live, boasting new fixes and tweaks

 

Hey, Anthony from Decentral here. Many of you who have been using Jaxx for managing your DAO tokens have noticed that on the last couple of builds, Jaxx had trouble detecting DAO balances in the absence of an ETH transaction. 1.0.4 fixes this; DAO tokens sent or Shifted into Jaxx should no longer require an ETH transaction to become visible. This update is now available for all versions of Jaxx except for iOS. We are making an effort to get updates out swiftly on all versions, but Apple’s review process for iOS devices is proving to be a bit of an obstacle.

 

Please note that users *will* still need to have at least a small amount of ETH in DAO-holding Ethereum address(es) in order to be able to transfer their DAO tokens between accounts or out of Jaxx.

 

We’ve also added a couple more fiat base currency options (the Mexican peso and the Norwegian kroner). If there are users out there who want to see more added, we’d love to hear from you!

 

To iOS users who have been wondering when they can expect the ShapeShift update: we’re wondering the same thing. That version of Jaxx has been languishing in Apple’s review process for several times longer than normal, and we aren’t sure why. We’re just as anxious as you are!

 

Many of you have also been inquiring as to when our in-app DAO Voting and Proposal viewing system will be in place. We are still hard at work on it and hope to have it ready by next week. We have much of the back-end work done, we just need time to make sure that going live with it won’t adversely affect Jaxx’s general usability.


We are also still at work on RocketDAO, our web-based command centre for The DAO through which users will be able to browse, create, submit, and vote on Proposals, This is being developed in tandem and we are hoping to launch it in close proximity to the Jaxx voting capability update in order to ensure a seamless experience for all users.

 

Those of you who follow us on Twitter at @jaxx_io may have seen that we want the broader community’s opinion on which coins and tokens should be integrated into Jaxx next. We’ve already seen quite a few hands go up for Lisk, Dash, and Digix, but we would love to get more feedback, so please chime in at info@decentral.ca.

 

All versions of Jaxx can be downloaded from the Jaxx website.

Announcing New Dev Tools for the Community – 7 Days of Jaxx Extended

 

 

62981e6c77b0152e6b06455eb0169cffHi there! Exalted Materialization Sorceress (aka Decentral CTO) Chris here.
First things first: We’ve lied to you; “7 Days of Jaxx” isn’t actually 7 days. We’re going to keep the announcements and launches coming well into next week with even more reveals and projects. We’re on a roll and we’re not ready to bring it to a halt just yet, in fact, some of the most exciting stuff is still to come. Today we’re announcing a new project that will be of specific interest to the Ethereum and DAO dev community.

 

While Ethereum is one of the most exciting decentralized technology platforms to have emerged over the last few years, the Ethereum dev community has been hampered somewhat by the limited number of comprehensive, publicly accessible points of access to the Ethereum network. As part of our continuing mission to support the Ethereum and DAO ecosystems, Decentral is pleased to announce that we’re constructing an API built on a new, full Ethereum node.

 

This API is being developed in conjunction with CoinFabrik, and over the course of the following month, will become available for a selective rollout with interested partners to test load balancing and request queues. Our plan is to offer the same service to the public with a lower request threshold until our deployment architecture is fully tested and tuned. What’s more, this API will support a full DAO node structure, including the ability to query addresses for their voting history and DAO token transaction history, as well as detecting which accounts are tied up in Proposals and for how long. This API will allow for greater interoperability for Ethereum web app devs and contribute to the overall health of the ecosystem by allowing for additional redundancy. If you’re interested in participating in our trial phase, please email me at chris@decentral.ca.

 

The first live deployment of our API (domain to be announced) will be within Jaxx itself, and is already helping to support our DAO integration process as well as our existing Ethereum functionality.

 

Our rollout continues tomorrow with Day 7, and will resume on Monday with Day 8.

Why Ashton Kutcher & Akon are Tuning into Blockchain Technology

For many, especially individuals content with the status quo, it is unfathomable to predict the progress of future technology. For others, the idea of using decentralized strategies to further our technological autonomy has fueled ambition to create new and disruptive technologies.
 
For example, the blockchain is a technology that allows databases to be shared across a network of computers. Information on the blockchain exists on all computers (or nodes) on the network, and each block represents an up-to-date record of whatever information is being stored. The first and best-known application of the blockchain to date is the digital currency Bitcoin. However, the technology has many other potential uses, some that could have the capacity to reframe our social relations and power dynamics. The blockchain’s ability to facilitate transparency and disintermediate trust suggests blockchain adoption will bring on a paradigm shift in our culture.
 
So what do innovations like these mean to technophobes or people not particularly well-versed in technology? Disruptive technologies like the blockchain could mean that individuals no longer have to rely on a centralized authority to control social, economic, and even political transactions. This realization has gained the attention of the following celebrities who have been able to help close the gap between tech fanatics and mainstream populations:
 

1) Ashton Kutcher

The actor, producer, and now investor, has had his fair share of success acting in films such as No Strings Attached and The Butterfly Effect, along with TV roles in Two and a Half Men and Netflix original The Ranch. Kutcher, who co-founded his own venture capital firm in 2010, A-Grade Investments, has been a longtime fan of blockchain technology and Bitcoin. In a 2013 video, Kutcher spoke at TechCrunch Disrupt NY about the power of decentralized technology:
 

“…what can decentralized technology do? Imagine if we could decentralize [the] issue of security… the notion that we could civically monitor each other in an anonymous way actually keeps the anonymity of the Internet, we don’t have to worry about Big Brother and that same infrastructure that built out bitcoin could be used in the security industry for mass good.”

 


 
Kutcher also sees the political value of blockchains — especially with regards to proposals by two of the current US Presidential candidates for remittance policies that would obstruct migrant workers’ abilities to send money to their home lands.


 
Kutcher’s advocacy as a leader in disruptive technology could encourage a growing number of people to embrace blockchain technology and cryptocurrencies. It’s what celebrities do best — create trends and start conversations on these topics.
 

2) Akon

Recording artist and producer, Akon, has been a vocal supporter of blockchain technologies and cryptocurrency. When he is not making hits, he is busy doing philanthropic work. Most recently, he helped provide electricity to over 600 million individuals across Africa. Through his cryptocurrency advocacy, Akon has been a proactive voice for reclaiming personal autonomy through technology.
 
From promoting Bitcoin and digital currencies in his home country of Senegal, as well as across West Africa, Akon is hopeful for the future of charities and other initiatives. As he explains:
 

“Digital currency is going to be the future, and as you can see I can’t remember the last time I carried a wad of dollars in my pocket…there’s all these new innovative ideas, but one in particular, by the name of bitcoin… [it’s] going to change the world from a money transactional standpoint not just for Africa, but for everywhere.”

 
The message is clear: financial systems, as we know them, are changing. Blockchain technology has the potential to streamline access to financial services, override corporate influence and open up new markets wherever wealth disparity exists. This is not to say that this technology will immediately or permanently solve global economic inequality, but it throws a wrench into the system, empowering those who wouldn’t have had the chance to be prosperous. Celebrities like Akon are helping to make this happen.
 

3) Imogen Heap

As the only female artist to have won a Grammy award for engineering, the “Hide and Seek” singer has always been a leader in tech innovation in the music industry. For example, Heap invented and designed musical gloves to manipulate sounds with hand gestures that can be used to produce music.
 
Now, Heap has embraced Ethereum (co-founded by Decentral’s CEO Anthony Di Iorio), a decentralized blockchain platform that can execute peer-to-peer “smart” contracts. By working with coders to develop a publishing method that is provably transparent, Ethereum can automatically distribute payment for sales of all copyrighted content, essentially eliminating the need for a middleperson or centralized authority. Her Dapp (decentralized app), Mycelia by Heap, will allow individual components of songs (such as a beat or a hook) to be licensed and monetized, with the owner of the content losing less (or none) of their revenue to corporate rentiers.
 
This concept isn’t restricted to music. Since the digital age, creative industries such as books, films, and visual art have experienced a loss of control over their content. When physical properties get digitized, they can be reproduced and shared by a global audience without creators receiving revenues from it. With the blockchain, respect for artistic property is being reclaimed and Imogen Heap wants to be the leader of the revolution. Her single “Tiny Human,” which is only available for purchase with ether (the fuel that powers the Ethereum network), is solidifying Heap as a foremost innovator of music distribution using blockchain technology.
 

4) Richard Branson

Entrepreneur and billionaire Richard Branson has also been an avid promoter of Bitcoin and blockchain applications. In addition to acting as an advocate for cryptocurrencies and disruptive technologies, he has invested in cryptocurrency companies (e.g. BitPay), hosted an exclusive digital currency conference on his own private island, and onramped Bitcoin as an accepted form of payment for his space travel initiative, Virgin Galactic. In a discussion with Argentinian President, Mauricio Macri, Branson outlines how Bitcoin can offer individuals:
 

“Greater levels of control, freedom and scrutiny over what happens with our money, Bitcoin addresses these concerns and that is why so many people believe it represents the future. While many of us are excited about the possibilities Bitcoin has to offer, I’m not sure any of us would argue that it comes without problems.”

 
An extremely powerful and a high-profile celebrity, Branson can use his fame to spark overdue and meaningful conversations with decision-makers about cryptocurrencies and disruptive technology and, in turn, explore applicable use-cases.

5) Mike Tyson

Boxing bad boy Mike Tyson has been an avid participant in the Bitcoin revolution. Working in partnership with Bitcoin Direct, Tyson recently unveiled two Bitcoin-related initiatives: Mike Tyson Bitcoin, a Bitcoin ATM, and a digital wallet, the Mike Tyson Digital Wallet. Underlying both products is Tyson’s interest in increasing awareness about Bitcoin and encouraging non-specialists to use the cryptocurrency. As a celebrity, Tyson is interested in using his celebrity status to promote discussions about Bitcoin and its potential to incite positive change:
 

“People don’t really understand a currency based on numerical equations. I personally still don’t … but I’m grateful to be a part of the revolution and hoping that my participation in this space will lead to more conversations and help increase knowledge and awareness.”

 

 
While Tyson’s initiatives are still in their relative infancy, such endeavours offer insights into Bitcoin and blockchain technology test-cases. By investing in products aimed at non-specialists, celebrities like Tyson make accessible what may otherwise come across as exclusive or obscure technologies.
 
Disruptive and decentralized technologies are the future and we have just begun the journey. As more and more familiar faces get on board with blockchain technology, the gap between the tech industry and mainstream culture should definitely begin to narrow. Can you imagine our current society without the influence of the Internet? Neither can we. It’s everywhere. The question is, will blockchain technology be the next Internet, and what will its capabilities and influence be? All we know is that the future is here and it’s knocking on our doors. Will you let it in?

7 Days of Jaxx: What’s in the Box?

7 Days of Jaxx

 

Welcome to 7 Days of Jaxx! We’ve challenged ourselves to present 7 major initiatives, releases and announcements over the course of 1 week that we think the whole community will be really excited about.

 

We got the ball rolling yesterday with our launch of Jaxx 1.0 on iOS (let’s consider that Day 1), and tomorrow brings the rest of the Jaxx 1.0 rollout across the remaining platforms and devices. Today we’re revealing the revised design and concept for our Coin Card program. As for the rest, you’ll just have to figure ‘em out…

 

A couple of months back, we announced that we would be launching an initia2cards (1)tive that would enable the easy purchase of Bitcoin in Canada. Now, we are excited to let Canadians know that we’ve secured a partnership with Gateway Newstands, a Canadian company that has hundreds of convenience stores across the country, to stock Jaxx Coin Cards. We’re also excited to announce that we will also be adding Ether to the mix making it the first time ever Ether will be able to be bought with cash in stores. As we add more coins to Jaxx, these should also become available for purchase using Jaxx Coin Cards. Users just purchase the cards with cash, peel off a sticker to reveal a QR code, and scan it from their Jaxx wallet to import the funds, making the purchase and importing of coins quick, easy, and convenient. 

 

Jaxx Coin Cards are currently available only to Canadian users, but we believe our Cards are a much simpler, more efficient way to get quick access to funds than ATM systems or exchanges, and hope to expand the program beyond Canada’s borders in the near future.

 

Stay tuned for more exciting announcements as 7 Days of Jaxx continues!

Inside the Jaxx HD Upgrade for Ethereum

My name is Simon Howell, I’m a technical copywriter and support specialist at Decentral.
 
This past Friday, Kryptokit released Jaxx 0.0.17, which included the first Ethereum wallet to comply with HD standards. For the uninitiated, HD stands for “hierarchical deterministic. This means that the Jaxx HD upgrade generates a new address every time funds are sent to the latest address. All previous addresses can be reused, and all addresses are derived from the master mnemonic. The HD standard was conceived as a way of minimizing the reuse of addresses – frequently reused addresses are much less private.
 
In the leadup to this release, our team (including our CTO Chris Forrester, the architect of this and other key Jaxx features) had many conversations about how best to handle the migration path for the Jaxx HD Upgrade. This upgrade was unlike all previous changes made to Jaxx, because upgrading to the new system required the generation of a new HD address that would not automatically store users’ funds, which meant they would need to be sent there.
 
This created a potential ethical issue, because transferring users’ funds from one address to another would incur the usual Ethereum transaction fee: .00105 ETH. Admittedly, that’s not a large sum, but subtracting it from users’ balances without asking just didn’t seem right, and even the considered option of refunding users wasn’t practical (especially as it would violate the Kryptokit philosophy of not collecting user info), so we had to rule out simply forcing the HD upgrade and transfer.
 
On the other hand, we considered giving users the option to decline the upgrade entirely. We decided against that as well, both because we believe there’s a clear need for Ethereum wallets to support HD standards in order to provide greater security, especially as Ethereum grows in prominence, and because making it optional might make future updates extremely complicated.

 

jaxx hd upgrade

 

The migration path we landed on was a hybrid approach: the upgrade itself was mandatory, but we left it up to users whether or not to let Jaxx make the transfer of funds. Users who declined to transfer their funds could still access their old (non-HD) address and private key via the Display Ethereum Keys screen – from there, the funds could be imported into Jaxx or any other Ethereum service that supports private key imports.
 

The Catch

We knew that no matter what migration path we chose, there was bound to be some confusion – HD is not necessarily a widely-known or understood standard within the Ethereum space, which means users might not appreciate being told that they will have a changing address all of a sudden. While there’s been some concern and a few cases of outright frustration, by and large, the response has been very positive, and most importantly of all, not one user has lost access to any funds as a result of this complex upgrade.
 
For any users experiencing issues with their balance not showing up after the transfer is made, or who are running into a “nonce too low” issue when attempting to Send, we would advise writing down your master mnemonic, uninstalling Jaxx, reinstalling the latest version, and pairing in your master mnemonic using the Restore Wallet function.
 
Today, we released version 0.0.18, which addresses the issues faced by some users as a result of the Jaxx HD upgrade. Users who declined the HD transfer should have an easier time accessing their non-HD private key, with the “one and a half minute” loading time eliminated. Users upgrading to HD for the first time (e.g. users who missed the 0.0.17 upgrade) should more reliably see their balance in the new wallet without having to do a re-install / re-pair.
 
This latest update would not have been possible without detailed feedback from our users – thanks to the whole community for trying out Jaxx and for being patient as we roll out these unprecedented features. If you are still experiencing any issues after installing this latest version, or have any general questions, don’t hesitate to get in touch at info@kryptokit.com.
