Hello.

We'd like to inform you about implementing NANO into HODLER Wallet.

We already have the infrastructure needed to support NANO transactions, generating addresses and private keys and securing them, the backup system, and mining blocks needed to send transactions. Possibly as soon as this week we'll be able to release a closed version of HODLER Wallet with NANO support for the people who by sending an email titled “NANO TESTS” to feedback@hodler.tech declare their willingness to participate in the tests.

Jokes about fee used to send transactions are popular among the NANO community. We'd like to include one of them in our wallet's interface in the place used for setting the miners fee with other cryptocurrencies.

Placement of the NANO fee joke:


Because of that, we'd like to announce a contest for the best NANO fee joke fitting our wallet.

The prize:
including winner's signature under the joke with a link to his profile
satisfaction from winning

The rules:
Start: on the day of announcement
End: 14.02
The joke is to be placed on an edited GUI:  https://hodler.tech/manuals/HODLER-NANO-FEE-JOKE-CLEAN.jpg
Send your work to feedback@hodler.tech with a link to your social media profile
Fee-joke can be in either visual or text form


We encourage you to spread this information among the NANO community. We are very proud to be possibly the first multiwallet to include NANO among its supported cryptocurrencies. We consider NANO to be a great project that should be widely discussed by the entire crypto community because of how open this project is to solving the problems many people face, including its use of very innovative method of transaction processing, fighting against transaction spam and implementing 0-fee.

Best regards,
HODLER.TECH Team

The wallet is to be a multi-task platform with an exchange to FIAT, integration with DEX, BTC anonymization by Monero. I encourage you to follow our blog if you want to be updated: https://steemit.com/@hodler.tech

HODLER Wallet 0.4 has been released!

Among numerous small improvements, a couple of more important ones can be highlighted:

- Keypool – new address for each new transaction. Subsequent transactions will be received to new addresses, while the change mechanism will send coins to addresses with positions higher than 1,000,000 in the pool. This will greatly improve the privacy of transactions, and automatic mixing will help to obfuscate the real address of the sender. The longer wallet is being used, the more diffused and mixed user's coins will become. It's a major change in the wallet, and one that we have tested thoroughly. If you happen upon any issues with synchronization, they can be fixed by restoring the user's profile with the “QR Encrypted Backup” or “Mnemonic Seed Backup”. In case of any problems, contact us at support@hodler.tech.

- New look of the app – intended to improve the clarity of displayed information, and make using the wallet even easier. The application's UI will be further improved in the future with new icons making it easier to use particular features of the wallet.

Windows version and the APK file were published at the usual link:
https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/releases/

The new release was also added to Play Store, and it will take up to 48 hours for it to update.

We hope that you will enjoy using the new version of HODLER Wallet!

Hello. ICO was very quick, we collected funds that allow us to develop the product. Our token is HODLER.TECH (HDL) https://www.altilly.com/market/HDL_USDT

We have almost ready next few changes in the program:
- a new design of the application,
- keypool (to improve the privacy of the transaction),
- many minor changes reported by the community,

We are also finishing changes that will make our apps 100% compatible with the bitcoin.org standard in order to obtain their recommendation. The list of the requirements is very long, but almost all of them are already implemented in HODLER Wallet:
https://github.com/bitcoin-dot-org/bitcoin.org/blob/master/docs/managing-wallets.md

We have an overview of our application by Bitcoin.org will improve the confidence in our software for people who are not programmers and are unable to verify the code on our Github:
https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet

The next task is to add the NANO, XRP and Monero cryptocurrencies and integrate the HODLER Wallet with DEX (Decentralized Exchange) to enable private and secure coin exchange in the application.

Thank you for your interest

New release of HODLER Wallet has been published. Windows version, APK package and source code can be downloaded here: https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/releases/tag/0.3.1

Application installed from Play Store should update automatically within 48 hours.

In the current release moving wallets from smartphone to pc takes only few seconds thanks to the option of displaying a decrypted seed in QR form, which can be scanned and exported to another device – from pc to pc, phone to pc, or phone to another phone.



Another interesting new feature is the possibility to generate an encrypted paper wallet (including an instruction on how to restore it) with just one lick:



This is how the paper wallet looks like:



The next update will improve the quality of software, and after that we will again start adding new functionalities and cryptocurrencies. We hope that you'll enjoy using the current release of HODLER Wallet.

We have made pairing of wallets between different devices and platforms easier. Encrypted QR Backup is now displayed in the wallet, all it takes is too scan it with a laptop or phone camera to synchronize two devices. Troublesome and dangerous sending of the seed is no longer required. Encrypted seed in a form of QR code can be stored online, as to decrypt it user's password is needed.

Moving of balances into another device, including from computer to phone and vice versa, now takes only couple seconds:




In the next release we will also include the option of generating a full, encrypted paper wallet and export it from the device. In all cases to open it the password will be required. You can try by yourself to crack the wallet that we're publishing, it's our official wallet. If you try it you will get to know what the term "key stretching" is: https://en.wikipedia.org/wiki/Key_stretching

Tomorrow - Nov 27, we will update our application: HODLER Open Source Multi-Asset Wallet, Bitcoin SV will be available:

We prepared Bitcoin SV Block Explorer too: https://bsvexplorer.info

Thank you for your ideas and support. We will consider it. In connection with preparations to add Bitcoin SV fora, we would like to present the block explorer of this cryptocurrency. This is something that every project should have: Bitcoin SV Block Explorer:  https://bsvexplorer.info/

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.

@peter0425 See you at the next infrastructure tests tomorrow!

Hello.


It's time for our wallet to improve its design and, in addition to its functionality, it also had an interesting appearance and was pleasant to use.

We are looking for a person who will take care of coding the walet design (Firemonkey). We do not require much experience, we only expect your portfolio that we like. Offers, links to your portfolio with dates and your financial requirements should be sent to: contact@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

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.

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.

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.
