HODLER Wallet - The Only Open Source Multi-Asset Wallet

[wgd]

Very interesting project
Keeping my fingers crossed!
I gave you my Merit point.
I think this topic should have significantly greater interest

About Retailer mode:
Maybe instead of sending every small transaction it would be better to set a margin position on exchange?
F.e retailer get 0,0001btc 0,00005btc 0,000002btc etc  sending every payment in single tx would be uneficcient...

You have an unusual idea, have long been watching. I wish you good luck in development, I as a HODLER, need it))

Thank you all for your support. What do you think about adding NANO cryptocurrency to HODLER wallet? https://coinpaprika.com/coin/nano-nano/

In the current edition, you can export private keys in HEX and WIF format (compatible with all wallets that allow you to import).

In the next release we will add the DASH Instant Send functionality.

If you lack some functionality, we invite you to offer it on our GitHub https://github.com/HODLERTECH/HODLER-Android-Multi-Asset-Wallet/issues

@wgd Thank you for merit!

Good work on this, missed the announcement, but I'm sure I'm not the only one looking for such a wallet. I'll probably always stick to my current client for Bitcoin, but a good open source alternative is sorely in need for all those other tokens/alts that we inevitably come into. The Jaxxs and Exoduss out there lack this feature, and as such, will never be a true solution for most of us.

Will still be a while before I commit to installing - any chance you'll hop on to the current bandwagon of atomic swapping at some point?

Thank you all for your support. What do you think about adding NANO cryptocurrency to HODLER wallet? https://coinpaprika.com/coin/nano-nano/

Every new coin added is a good idea! I think you could talk with bitcrystals developers (as BCY will be delisted at bittrex - due to "security" regulatory issue - there are many people looking for place to store their BCY and Hodler.tech wallet could be interested for them! I am aware it could be difficult as BCY is counterparty XCP token, but I think it is worth at least to make an attempt to talk

[HODLER_TECH]

Thanks. At the moment, we're adding new coins. We are preparing the support of RavenCoin, DigiByte, NANO and Ethereum Classic. In the first place, we add projects that the community proposes to us and which offer HODLER promotion in their social media. We invite you to suggest interesting coins, we will contact them.

Atomic Swap is an inevitability, we are looking for the best solution in this matter.

We've added the programming environment configuration instructions for HODLER's own compilation, please check: https://github.com/HODLERTECH/HODLER-Android-Multi-Asset-Wallet/blob/master/README.md

The iOS version is already advanced, we are waiting for the formalities related to the D-U-N-S number, the company's Appstore development account. We will inform you about the progress.

[HODLER_TECH]

Until the end of next week all the packages will be ready to be sent. Everyone who sent us their address before 19.10.2018 will be informed by email when the package is posted and when it is expected to be delivered.

If you want to confirm your addition to the list of people who will receive the hardware wallet, please send your address to contact@hodler.tech. Unfortunately a lot of people have given us their addresses who never participated in our ICO – they have been excluded. In case you don't receive a confirmation that the package has been sent by 02.11.2018, please contact us to verify the ownership of 100,000 HDL tokens. The verification means signing a message with the address where the tokens are, or if this is problematic, sending us 1 token from the address used for purchase during ICO. People who applied from an email address used during ICO don't need to be verified.

We are interested to hear your opinions after you unbox and configure the device for the first time. The last update, with a working, secure OS updater is quite impressive. A video presentation of HODLER Hardware Wallet will be published after the prototype is sent and we receive your feedback. We are convinced you will see the amount of work that we've put into this project. We hope your opinions will help us improve the product even further so that it will impress the buyers when we start selling it, which we plan to do in the first quarter of 2019. Some of the interesting ideas we had will not be finalized before the prototypes are sent – one of them is encryption of the file system done by the starting script of the OS. Thanks to the easy to install firmware updates this will be implemented soon. Of course this is just the second layer of encryption. The main one, encryption of all sensitive wallet data, is present from the start.

Your promotions are awesome! You also great reviews on play store. ETH devs have released an Android app that is multi sig and you can sign offline.  The private keys never connect to the web. I know it is a huge ask but it would be nice to see those features for other crypto assets.  What are your thoughts on those features.

[HODLER_TECH]

Thank you for your kind words! We know this solution, everything that improves security and makes it easier to use cryptocurrencies is interesting for us at the stage of building the portfolio. We'll check it. Thanks for the suggestion.

Yesterday, we have exceeded 500 mobile app installations via the Play Store. DASH promised to add our wallets (all versions) to dash.org website after the release of iOS and Linux applications. We are also trying to put our apps on bitcoin.org, bitcoincash.org and litecoin.org. We hope that you will like our wallet even more, when we implement the changes you propose. We invite you to add your suggestions to our Github: https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/issues

Issues with "pending status" are under development at this moment: https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/issues?q=is%3Aissue+is%3Aopen+label%3Apending

Here you can see what we have finished working on lately, many of these are your suggestions for which we would like to thank you again.

Great progress Hodler Wallet team!
Your activity there is amazing,
and your development too.
I think your project could be hidden crypto gem soon

PS. Have you already contacted bitcrystal devs?

[HODLER_TECH]

Yesterday's tests were a true war. If you didn't participate, you missed a lot. I'll try my best to describe the whole thing:

1. 16:00 – 2 hours before the tests we start to prepare the wallets: 100 wallets with $20 in each
2. 16:30 – A lot of users opened their wallets, the servers slowed and the application started to “take its time to think”.
3. 17:00 – Even more wallets running, it's harder for us to make new ones and our progress slows.
4. 18:00 – Over 600 people starts the wallet at the same time, nervous awaiting for the first backups begins.
5. 18:05 – First 20 wallets with passwords are published.
6. 18:06 – Server I fails; that was not the intended scenario. According to plans the server should have passed the surplus traffic to Server II and they should both work on synchronizing the wallets. Since this failed, Server II took the entire traffic and also slowed, through it kept working.
7. 18:30 – Some impatient people turned off their wallets and the server started to improve its performance, the application was still a bit slow but usable.
8. It turned out 4 of 20 backups were empty – the servers were congested during sending funds to these wallets, and sending was interrupted after a moment.
9. 19:30 – All wallets are restored.
10. Summing up the results, licking the wounds, burying the dead – these still take place.

We will soon publish our conclusions as well as fixes to the application which will make the second round of tests (81 wallets with $20 on each) go more smoothly. We are definitely happy with the enormous interest the community displayed towards HODLER Wallet and our infrastructure tests, which surpassed all expectations.

[HODLER_TECH]

Some conclusions right after fixing the servers:

1. Bitcoin can't use the same server as the other coins. It has to have a full, dedicated server + one mirror server. We still have to fix switching between the two servers to disperse the traffic.
2. We need to start creating local backups of the utxo database more often, so that restoring it will be really fast. At the current configuration it takes about 3 hours, it will be brought down to maximally 30 minutes.
3. Synchronizing each coins will be separated into independent threads with a specific TimeOut. In case of a single coin malfunction, the entire wallet won't crash trying to connect to a malfunctioning server.
4. The list of available coins will be shown during the first configuration, in order not to needlessly check balances of the coins the user does not use – it will unburden the infrastructure.

The test we organized turned out priceless. We spotted a lot of little elements that can be improved.

The second turn of tests will take place on Friday 19:00 CEST.

You are doing phenomenal work HODLER Wallet development team!
I hope it will bring amazing results soon! As SIRIN Labs Finey blockchain-phone example showes people need such kind of technology - so there is definitely market niche for HODLER, so keep working! I believe in you!

[HODLER_TECH]

@wgd

Thanks for support. There is still a lot of work ahead of us. We are currently looking for a person who will take care of UI / UX and will create a new, better wallet design. Required experience in Firemonkey. If you know someone who could help us, please contact us: contact@hodler.tech

I'm really amazed how you just moved in just the couple of months. Good post-mortem reports and I love to see those improvements coming in the next weeks or so. I'm going to continue to monitor the progress and I'm glad to be part of this amazing project (signature campaign). Keep up the good work guys!!!. As far as person you are looking for, you may want to post it in Services (if you hadn't done so).

@peter0425 See you at the next infrastructure tests tomorrow!

You are moving forward as planned

If you some day need help signing your token up different places, telegram support and spreading the word I would love to help.

I got 40$ from your competition. Thanks a lot.

This time everything went great. The new, 0.2.9 release of our application, updated using all the data we collected during the previous test, is much better than the 0.2.8 release. The new, optimized synchronization system is much lighter on the servers, the wallet no longer slows down when traffic is high, and the balances are synchronized much faster. Improved traffic control system divides the traffic smoothly and evenly on all servers. The servers proved themselves to be able to survive the harshest of situations, and after the traffic lowers down they can get back to normal immediately. The only issue we discovered is huge encumbrance during ETH and tokens synchronization, and we will start working on it right away.

The 0.2.9 release also introduces a new token Algory, a new coin DigiByte (Legacy + Segwit), support for all LTC addresses (Legacy, Multisig, Segwit) and the option of choosing preferred coins during the initial configuration. This version of our wallet is a great advancement and it will soon be introduced to our hardware wallet.

Currently we're working on the iOS release as well as adding the support for NANO.
