    Just upvoted and resteemed your post on Steemit.
    If you want, I'd be willing to write an article about Hodler wallet. I have around 700 (real) followers on Steemit, so that will give you some more exposure.

    Any idea when you'll add the ability to lock funds? I think that would be great to mention in the article.

    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

    Interest discussion about Hodler started in the web-wallets board : https://bt.irlbtc.com/view/5098468.0

    I just installed the 0.3.2 version for windows. I think i will try it later today, i think Hodler would be a very useful tool to store multiple crypto-funds in one wallet. I didn't hear about your ICO. Does the wallet run a coin within it?

    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

    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.

    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 Smiley

    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

    2. primary question. what function you use for generation priv. keys. Exist VUNNERABILITY generation mechanisms when hacker may sweep all keys generated wallet.



    1. Why? I wrote this wallet from a scratch, always focused on security. This code is native, do not use webview or other things which may be vulnerable. It's all native
    2. Look at function priv256forHD in misc unit, private keys are created from concatenating master seed and given coin params, then hashed. It's not inversible, so hacker must own a masterseed. Masterseed is generated with ISecureRandom + data from move sensor + taps/clicks  etc, then hashed.
    MasterSeed is then secured with TCA alghoritm for key streching and SPECK. In early version of HODLER every single private key were also secured with key strech algo but we left this feature because it takes too long for generate pool of addresses for receive/change feature.

    Heres an idea...

    With regards to the timelock feature, you could have multiple options. It could be literally impossible to access your funds, or there could be other options where the funds are accessible (in case of emergency etc) but you place a self imposed and self determined percentage penalty if you take out the funds before the deadline, (the percentage penalty should be shrinkable as you get closer to the deadline as well in a proportionate manner). So you have established the option for a disincentivising system for the user to remove their coins early, and created a source of funds for somebody too! Where should the penalty go? Well the user should be able to choose this too. Either to the developers, or to be distributed to other users of the wallet. This would act as an interest acruing mechanism for everyone who deposits funds in the wallet! So everyones a winner and it incentivises more adoption as well.

    I found the OS you created for j3 very interesting. And I understand why you charge for it. For some time now I've been looking for an android version that could be used exclusively as a multi-wallet. Any plans to create and maintain android versions for other smartphones?

    We'd like to introduce the only fully Open Source, free multi-asset and multi-platform cryptocurrency wallet in the world.

    We find it absolutely crucial that a cryptocurrency wallet should be completely Open Source. We explained why we think so here: https://steemit.com/source/@hodler.tech/hodler-the-only-multiwallet-that-s-open-source-and-why-it-matters

    Basic specification of HODLER Wallet:

    1. You have a full control over your private keys, nobody else but you can access them, you can export them to other wallets.
    2. No private data of the user is ever collected.
    3. Transactions are always generated and signed on your device. No sensitive data is ever send to an external server.
    4. Don't trust, verify - thanks to being fully Open Source, the application is completely transparent. Any modifciation or update of the software is immediately verified by the community of security experts all around the world.

    Official website of HODLER Wallet: https://hodler.tech

    Supported platforms:

    Android
    - Play Store: https://play.google.com/store/apps/details?id=tech.hodler.core
    - APK version: https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/releases/

    - EXE App: https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/releases/
    - Source Code: https://github.com/HODLERTECH/HODLER-Open-Source-Multi-Asset-Wallet/

    In the future we will add the support for following platforms:

    Supported cryptocurrencies:

    - Bitcoin (BTC)
    - Bitcoin Cash (BCH)
    - Litecoin (LTC)

    - Every ERC20 token: by default we list EOS, Tronix (TRX), VeChain (VEN), Binance Coin, OmiseGo (OMG), ICON (ICX), Zilliqa (ZIL), Aeternity (AE), Bytom (BTM), 0x (ZRX) and our HODLER.TECH (HDL). Any other token can be easily added manually by pasting the contract address. We also implemented a unique feature of automatically scanning for and adding tokens to wallet balance: just import your MyEtherWallet private key, and all the ERC20 tokens you own will be automatically added to the balance of your wallet.

    In the future we will add the support for Ripple, IOTA, Cardano, Stellar and ultimately all of the top 100 most popular cryptocurrencies.

    Features of HODLER wallet:

    - Easy and safe backup of the entire wallet done with our original solutions called HODLER Secure Backup and Encrypted QR Code Backup – read more about these solutions here: https://steemit.com/bitcoin/@hodler.tech/introducing-hsb-hodler-secure-backup. Of course our wallet also supports the traditional method of using a mnemonic seed.
    - Full encryption of wallet data to protect it from unauthorized use
    - Carefully thought out default settings allowing everyone to easily send and receive cryptocurrency, but with advanced options allowing for full customizations of transactions, like setting custom fees fitting to current network traffic
    - Many fiat currencies to which you can convert your cryptocurrency: PLN, EUR, GBP, USD, CAD, INR and many more coming in the future
    - Many languages supported: English, Polish, German, Spanish, French, Japanese, Chinese and many more coming in the future
    - Full customization and organization of the wallet: moving, removing and adding cryptocurrencies as you see fit, as well as renaming coins on the list and adding many addresses for a single cryptocurrency
    - Cryptocurrency finder for the coins listed on HODLER main screen
    - ERC 20 Scanner:  add tokens with one click.

    Incoming features:

    - Support for Decentralized Applications (DApps): we seek to support decentralized solutions to help connect the world through a blockchain
    - Many more coins: our goal is to suppport all of the most popular cryptocurrencies, as well as all the ETH, Lisk, NEO and Cardano tokens
    - „HODL My Coins” feature: a HODL option for all or some of your funds – set a restriction on your wallet to HODL cryptocurrency for a chosen time
    - NFC Payments: secure and contactless transactions - the new generation of mobile payments
    - Retailer Mode: is our way to make the vision of cryptocurrency acceptance in stores worldwide a reality. HODLER’s Retailer Mode allows the acceptance of cryptocurrency payments even for people with hardly any knowledge of them. All it takes to enable payment acceptance is switching the Retailer Mode on. The transaction will happen similarly to transactions made with credit and debit cards. Read more about it here: https://steemit.com/bitcoin/@hodler.tech/cryptocurrency-payment-terminal-for-high-street-
    retailers-retailer-mode-in-hodler-wallet
    - Pay-to-Email & Pay-to-SMS: send your coins to people who don't know much about cryptocurrency and do not have a wallet

    We invite you to download the wallet, testing, and send comments on its functionality!

    I’m an iOS user. Is there a general projected timeline for iOS app release?

    I saw Holder wallet today for the first time, and I don't know much about it, but I like the dark style.
    Does it have ability to sign-a-message for Bitcoin?
    So far I know that only Electrum and Coinomi have that option

    Two years later, the thread had no replies, the website is down but ... the wallet has 1000 downloads on Google Play. Whats up? Is this project still alive? On GitHub there was also a long silence since 2019.

    I'm poking around for inclusion in WalletScrutiny: https://walletscrutiny.com/android/tech.hodler.core/
