What does a hard fork mean for Jaxx Users?

The ongoing debates surrounding consensus, scalability and governance of decentralized system have led many in the Bitcoin community to believe that there’s a possibility of an hard fork on the horizon. I want to take this opportunity to let Jaxx users know that you will never need to take any actions leading up to a hard fork. I’d like to also provide more information to our users and the community on how Jaxx handles events, such as hard forks, and how we make our business decisions regarding similar situations.

Let’s first start off by explaining what a hard fork is. Due to the governance structures of decentralized blockchains, there will always be a level of dissent between important participants of the networks. Under certain circumstances, due to dissent among these participants, a fork of the blockchain occurs resulting in two competing chains that move in different directions. Although these blockchains will share identical information up until the fork occurs, coin holders would end up with funds on both chains along with identical private and public keys.

At Jaxx, we don’t pretend to be oracles or speak on behalf of our users or entire communities. Although we attempt to predict where the space is moving and make business decisions accordingly, we’ve learned over the years that taking a “hard stance” tends to be counterproductive, especially when situations rarely end up playing out as many would expect.

Jaxx is a multi-currency wallet that supports many blockchains and technologies with plans to support many more. Think of us as a multi-platform interface (or browser) for blockchains that allows users the ability to view, control, manage, exchange, send, and receive many of the leading digital currencies available today. Given this multi-chain multi-technology approach that provide users choice and control, we believe competition to be invaluable and we will continue to support emerging blockchain technologies and projects that we believe have merit.

The most important thing to know when dealing with hard forks is that Jaxx users really need to do nothing on their end: You don’t need to move your funds before a fork, nor do you risk losing your funds after. Unlike an exchange that holds the keys to your funds, one critical feature of Jaxx is that users are in full control of their keys. Jaxx doesn’t have access to your funds (keys are created and stored client-side and never sent to our servers), nor are we custodians of your funds (blockchain holds the funds). No matter what decision we make once we’ve evaluated the results of a fork, users will always be able to export their private keys individually or altogether via a Backup Phrase, and import them into another service The difference with holding your funds on an exchange is that you are always at their mercy regarding decisions they make; you do not have control of the keys to your funds, they do.

I’ll reiterate that with Jaxx there is nothing you need to do leading up to a hard fork. Should a fork occur, know that we will monitor the situation and events following the fork. We will also provide guidance to our users and details of any actions we plan to undertake as a result of the fork. One suggestion I will make is to occasionally check our social media channels and our in-app bulletin messages (Menu -> Bulletin) for any alerts or messages that might impact our users.

Jaxx – Monero Integration Update

For those of you that don’t know we at Decentral recently joined the Monero community and are working on integrating Monero to our Jaxx Wallet. Jaxx is a free multi-token, multi-platform light wallet that’s dedicated to uniting the crypto-ecosystem and providing an interface to Blockchain tech (in a similar way the browser unleashed the power of the internet to the masses). Among other things, it is the goal of Jaxx and Decentral to allow people to be in full control of their digital lives. All keys in Jaxx are held client-side and a single 12-word backup phrase allows for the derivation of the keys to all tokens we support, and will ever support. Also, all our products are design and user experience driven as we make stuff for the masses, so that people (like my non-technical Dad) can have a great experience.

One thing I’d like everyone to remember and keep in mind is that we’re still very new to the Monero community and much of the history of the project is not clear to us still. As you read the rest of my message, please keep this in mind and know that we are not trying to call anyone out or cause conflict in the Monero community. We just want to see Monero thrive.

Here we go.

Monero integration has been on a radar for over a year and over the past weeks and months we dove headfirst into XMR and have since spent more than 400 hours working on this particular integration. During this time we have gained massive knowledge on the inner workings of the Monero protocol, and of the Monero development ecosystem. Our goal is to provide a lightweight (~3 meg) solution for the Monero community that will allow them to manage, send and receive XMR on pretty much any platform or device.

As a result of working to integrate other projects, our 3 years of experience developing wallets, through my experience as a founder of Ethereum, as an early Bitcoin adopter and community builder, and via extensive research and code creation we’ve done for Monero, we believe to have determined the critical issues that are leading to problems with Monero growth and that these problems are hindering the adoption and success of the Monero ecosystem.

As such we are putting a call out for support from the Monero development community to help us break through these problems. We are confident that if these roadblocks can be bypassed, Monero has a great chance to flourish. We believe that unless solved, these issues will greatly hinder Monero’s ability to compete with projects that have similar features.

Before I get into the issues I want to explain and give some background on how our integration process usually works when we tackle a new project, then I’ll explain how things are currently working with the Monero Integration.

Our goal is to implement an XMR lightweight wallet in Jaxx that connects with a high level cryptocurrency API. In most cases (with our previous integrations) there is an existing client library to use for the particular token in question. We have a full stack blockchain development team of 9 that can go from modifying cryptocurrencies nodes to providing high level APIs. We first start any project by making feasibility analysis to check how easy or difficult is to integrate a light wallet with a cryptocurrency. When we see critical unsolved issues or roadblocks, we talk with the specific cryptocurrency team as early as possible. If they have the resources they help us to mitigate those issues. When they don’t have the resources to make the necessary changes, we take the responsibility for these tasks but they provide some guidance based on their expertise.

That’s how things normally work. Here’s how it’s working with Monero.

We researched the feasibility of providing a light wallet for Monero and found the main challenges to be:

  1. Non-existing lightweight client library support (for a project as old as Monero its peculiar no dev has done this)
  2. We would have to implement support for anonymization features.
  3. There are RPC (Remote Procedure Calls) API Limitations that would require changes in the Monero daemon

Here’s what we’ve been able to accomplish so far:

  1. Finish a Monero javascript client library
  2. Use the same approach as MyMonero re anonymization (e.g. persisting the viewkeys)
  3. Modify Monero Core to support a lightweight wallet.

Currently we are developing an API on top of monerod to provide additional web services.

Now here’s the problem.

We have realized critical issues that are difficult to solve at the RPC API level without the development community’s support. Basically we would like to get the global indexes in the transaction output via the RPC API, which are required for sending transactions, but when we call methods such as gettransactions we don’t receive this information. We also try to call the *.bin RPC methods as well but they return error code HTTP 404. Ok fine. If this method is not supported in monerod there are two alternatives: 1) either the core team can add them to make it easier for the entire community to build apps on top of Monero, or 2) we can modify the Monero node itself to add support for new RPC methods required for building applications (like the Jaxx wallet or any other wallet).

The problem with us choosing the second method is the amount of time it’s going to take us to “instrument” the code is unknown as this would be an intensive research project by people who didn’t work on developing any part of Monero. Like a needle in a haystack. Also, should we have to directly hook into the code it could become easily broken in the future as new code gets pushed by the Monero core team. If (and that’s a big if) we were to go down this route of instrumenting the code we would need a commitment from the Monero core team to accept the code push and to continue supporting it in the main branch.

Without either of these two options being completed it means that Monero as it is isn’t able to bring enough information outside of the node in order to develop a full wallet.

As mentioned in previous update posts, we’d like to thank Fluffypony for providing us with assistance with the integration. But we need more help than he’s been able or willing to provide. The issue is that his help has been limited as although he is a main contributor to Monero, he also owns MyMonero and has a profit incentive not to give away his “secret sauce” on the back-end. You see, MyMonero hooks right into the code and this coupled with him being one of the few main contributors on the Monero Github gives MyMonero an upper hand against other projects trying to create similar services.

We understand and accept Fluffypony’s motives and situation. He’s put a ton or resources and effort into Monero and into MyMonero. What we’d like to do is call on anyone else who may be able to help to break through these barriers. Please email me at if you would like to join our slack channel and see if we can crack the problem’s we’ve identified and are facing. We fear if we don’t have more assistance from core Monero devs to act as guides we (or anyone else for that matter) will not be able to bring the products and services necessary for the Monero community to flourish.

Have a great weekend all!

Jaxx Announces Rootstock Integration at laBITconf


Announcement comes as Rootstock officially unveils their smart contracts based platform


Buenos Aires, ARGENTINA – 5 November 2016 – Decentral, creators of the universal wallet Jaxx, announced today the integration of Rootstock’s token RSK “Smart Bitcoin,” into their suite of software products. Jaxx becomes the first blockchain wallet to effect the integration, which will give users an opportunity to access the testnet version of the token, powered by smart contracts secured by the bitcoin network. Rootstock is immediately available on 7 of Jaxx’s 9 platforms, with support for iPhone and iPad expected shortly. The announcement comes as Rootstock executives took center stage at laBITconf to officially unveil their platform to the world’s leading blockchain experts, fintech innovators and international reporters. The concept of Rootstock is to provide faster bitcoin transactions and larger scalability, with payment confirmations occurring almost instantly.


CEO of Jaxx Anthony Di Iorio said, “Rootstock’s platform is a remarkable way to enhance the the efficiency of transactions and in turn, the entire bitcoin ecosystem. We’ve seen great interest in their project and we are big fans of the development team. Jaxx is thrilled to add the yellow label version of their coin on our wallets, and look forward to adding the main-net version in the coming months.”


Rootstock is an evolution of QixCoin, a turing-complete cryptocurrency created back in 2013 by the same development team. Rootstock will facilitate over 300 transactions per second and confirms payments in less than 20 seconds. The platform will combine the capabilities of Ethereum with the security and transparency of the Bitcoin network, using sidechain technology and a merged mining approach.


Diego Gutierrez Zaldivar, co-founder of Rootstock said, “Rootstock is not new in that it inherits intellectual work from previous projects, but what is new, is the way we create economic incentives and the way we leverage on top of the bitcoin security model. Our partnership with Jaxx is a landmark one for us, because they produce full featured, easy to use wallets on more platforms than anyone else.”


The main-net launch of Rootcoin will occur in early 2017.




Jaxx CEO Anthony Di Iorio is available for interview.

Zcash goes live on Jaxx!


Integration complete on 7 of 9 Jaxx platforms.


Toronto, ON – November 1, 2016 – Decentral, creators of the universal blockchain wallet Jaxx, announced today that Zcash’s integration is officially complete. Due to significant community demand and interest in Zcash, Jaxx aimed to ensure the new coin was available as close as possible to its official launch date. As of Tuesday morning EST, Zcash is immediately available on 7 of Jaxx’s 9 platforms, with support for iPhone and iPad expected in the coming weeks.


Founder and CEO of Jaxx Anthony Di Iorio said, “There’s a lot of buzz and excitement around Zcash. Our team has worked hard to speed up the integration process, to test it appropriately, and to provide thousands of customers with access to this coin as soon as possible.”


CEO of Zcash, Zooko Wilcox said, “Although Jaxx wallet doesn’t presently support all of the advanced privacy features of Zcash, it is a very easy way for people to access, send, and receive Zcash coins. I’m excited about Jaxx adding support for Zcash because it works on many different platforms and devices and it already supports other cryptocurrencies like Bitcoin and Ethereum.”


Zcash works by way of zero-knowledge proofs; the protocol allows for two parties to receive verified information without knowing who each other are, or seeing the subsequent data exchange. Zcash trades and payments will see transactions published on a public blockchain, with the option of keeping the sender, recipient, and amount confidential.

Jaxx Blockchain Wallet To Add App Store-Approved Litecoin to All 9 Platforms

Fourth most valuable virtual currency will be live early October


Toronto, ON – September 21, 2016 – Decentral, creators of the universal blockchain wallet Jaxx, today announced plans to integrate Litecoin into its suite of software wallets on all of its desktop, mobile, and internet extension platforms. The integration will come into effect in early October, following significant community demand as well as pre-approval from Apple’s App Store development team, who last month listed nine approved tokens available on the iPad and iPhone. Litecoin, now just three weeks shy of its 5th birthday, is the fourth most valuable cryptocurrency by market cap, valued at approximately $180 million USD.

Jaxx Founder and CEO Anthony Di Iorio said, “We received countless requests from the community to add support for Litecoin, and we knew it was already accepted by Apple on the AppStore, so for us it’s a perfect fit and makes the most sense right now. Litecoin has stood the test of time; it’s very popular at number four, and it boasts better transaction times than Bitcoin.”


Charlie Lee, Creator of Litecoin, said, “I created Litecoin to complement, instead of compete, with Bitcoin. I’ve always envisioned a future where people transact in multiple different cryptocurrencies. Jaxx is one of the easiest to use wallets and I’m excited to be able to hold both my bitcoins and litecoins in the same wallet.”



Andrew Vegetabile, Director of the Litecoin Association, added, “Jaxx, like many of those within the Litecoin community, believes in the fact that we are part of one larger family of cryptocurrency. Having Litecoin integrated with Jaxx allows our community members, who are also members of other communities, to feel a sense of unity when accessing platforms that allow multiple cryptos. This partnership enables those cross-community members to access their various cryptocurrencies in one platform without having to worry about keeping up with multiple wallets and applications.”


Litecoin is one of the globe’s most trusted cryptocurrencies and a leading alternative payment system. In conjunction with its Jaxx integration, Litecoin will use Q4 2016 to carry out memory usage improvements, faster signature validation, SegWit integration, and potentially, confidential transactions.


Litecoin’s integration comes just a fortnight after Jaxx added support for Ethereum Classic and Dash before it. Jaxx will announce the addition of several more tokens for integration into their suite of wallets in the coming months.


“We have always been pro-technology and pro-choice. One of our primary goals is to give people options in a constantly evolving digital age. We are proud to be the one-stop shop for people managing their digital wealth; customers can now access their portfolio of coins, trade them, and hold onto their keys without having to trust a centralized exchange,” said Di Iorio.


Since launching in June 2016, over 50,000 users have downloaded Jaxx.

New Major Jaxx Release on its way; will include full Ethereum Classic (ETC) integration

ETC-post-Image-cropped***UPDATE – Ethereum Classic has been released!!***

A few weeks ago, I announced that Jaxx would not be integrating Ether Classic anytime soon. The rationale was twofold. First, I believe that we jumped the gun with our DAO efforts and wasted resources aiming to become a “DAO command center”. Lesson learned. Second, we had already committed to a short-term dev schedule that included the launch of Dash, a complete menu overhaul, new features that allow sorting and hiding of tokens and currencies, various other UI work allowing us to support more tokens, and a new express and custom wallet setup procedure for new installations of Jaxx.


Today I am happy to announce that not only were we able to complete these above tasks, but also, in our spare time, we were able to get ourselves ready for Ethereum Classic integration. In the coming days Jaxx will be releasing a major upgrade which will include full ETC support, including a simple way to split ETH / ETC right in Jaxx.


Ethereum Classic is the 6th highest blockchain token by market cap, and ideologically, I have never been averse to supporting it. If I was a maximalist, I never would have founded Ethereum and would still be proclaiming Bitcoin as the be all and end-all. I am pro-technology and all for individual choice. Jaxx shares a similar philosophy.


Adding ETC just makes sense for Jaxx: we’ve received tons of requests from both ETC fans and ETH fans and all those in between to provide integration. People need ways to store ETC outside of exchanges, and our customers (and I) need a simple way to split ETH as well as have an easy path to sell (via shapeshift), or manage their ETC. Soon they will be able to do so across 9 platforms and devices using Jaxx. The new release will be pushed in the next few days.


Jaxx Wallet Adds Dash Integration & New Custom Features


Toronto, CA – Today, Jaxx blockchain wallet has taken its latest step forward in its mission to become the definitive, cross-platform interface for blockchain technology with its integration of Dash, one of the most popular tokens in the cryptocurrency space.


The new Dash integration, which enables users to send, receive and manage their Dash tokens, marks the beginning of Jaxx’s next phase of development, which will see the onboarding of more tokens while helping to broaden and support the wider blockchain ecosystem with new back-end tools. As with previous Jaxx token integrations, users can now also buy and sell Dash directly in the wallet via the convenience of Shapeshift.


“Jaxx supports and is very active in the Bitcoin and Ethereum ecosystem, now we’re excited to be joining the vibrant Dash community”, stated Jaxx CEO and Founder Anthony Di Iorio. “We had put a call on social media asking which tokens we should add next, and Dash by far was the most vocal and enthusiastic”, Di Iorio continued. 


Released via an update across all 9 platforms and devices, the new version of Jaxx also marks the debut of a customizable multi-token display. This feature enables users to select the tokens they wish to have enabled and displayed, as well as the order they appear on the main screen. This new visual experience works in tandem with the recently added base currency display options and the overall redesign of Jaxx’s menu layout to make for a sleeker, more customizable user experience.


“It’s our goal to provide an interface and user experience for blockchain that’s tailored for mass adoption,” stated Anthony Di Iorio, “similar to what the browser enabled for the internet, or the graphical user interface did for the personal computer, continued Di Iorio.” Another key tenet of Jaxx’s approach to development and growth is to provide back-end tools and infrastructure that benefits and decentralizes the entire blockchain ecosystem.


Jaxx desktop, mobile, and extension versions can be installed at, or by visiting the Apple App Store, Android Play Store, or Google Chrome Store for their respective versions. For media inquiries and partnership opportunities please contact [email protected]
