It seems there still is a need for solution to keep your XRPs safe, while still having them available for occasional and sometimes even for more active use. Ripple technology is in many aspects ahead of Bitcoin and other cryptos. I find offline transaction signing one its best features. In today’s world, when no computer can be considered safe anymore, offline signing allows you to keep all sensitive information offline and thus secure and safe. I have prepared a set of tools that follows and leverages Ripple’s Reliable Transaction Submission. It will allow you to monitor Ripple network, ledgers, your accounts and balances. The offline part will also enable you to securely create new accounts, prepare and securely sign payments and submit such offline-generated payments to XRP ledger. For transferring offline generated data to an online device it uses QR codes and this makes active XRP use quick and quite convenient. Unfortunately, this package is not entirely suitable for beginners. It aims more at mid-experienced to advanced users. Also, I wanted to keep those scripts simple and plain and allow anyone to see, understand and inspect its source. This is why some results/error processing is just very subtle. More information, how-to, installation, syntax, examples, download: https://github.com/Duke67/xrptoolkit-nodejs Download: Node.js scripts (offline): https://github.com/duke67/xrptoolkit-nodejs Android app (online): https://play.google.com/store/apps/details?id=com.duke67.XRPtk The Android application is only available for download from Google Play store and it’s not yet open source (I may make it available later on). Even if not currently available for code review, this architecture can really give you a peace-of-mind because the real magic of this solution is that the online device only sees either public, or signed+encrypted information. iOS app – unfortunately not available now, who wants to develop it? Also, feel free to improve or enhance the toolkit or contact me with any idea you may have. Cheers!

I started this topic because I am tired of waiting for someone else to furnish a hardware wallet to the Ripple/XRP community. I'm a former product developer, with hardware and software experience. This project will need skill-sets in hardware development, micro-computer coding, internet coding, testing, and manufacturing. I feel that with the right group of people we can make a world class HW Wallet that will enhance the value of XRP (besides giving everyone a convenient and safe place to store their XRP). Beyond that, we can leverage the knowledge gained, with our experience, to go on to bigger and better things with Ripple. This project should be considered a commercial project, and sales profits of the wallet will be distributed to the team. In other words, this is a serious development project for experienced people, willing and able to put in the time and effort. If you are interested, please post here, talking about your skill set and how this could proceed.
