  1. Hi everyone, I see a lot of questions about paper wallets lately. Got some messages regarding paper wallets as well. This is my attempt at combining all my explanations in one howto. What is a paper wallet A paper wallet is a XRP wallet you can generate offline and print. When you generate a paper wallet, you generally print it (multiple times) and store the paper wallet in a (very) safe place. Don't store all the copies in one building, since you want to be able to retrieve a copy if something terrible happens. One of the advantages of a paper wallet is is that it's "unhackable" - if someone hacks your computer, your keys* aren't stored on it. Just keep them safe A paper wallet contains 2 keys (text) and most of the times 2 QR codes (one for each key). When your XRP is stored in your own wallet, the XRP's are yours. When your XRP is on an exchange, you might loose access to your XRP's (if the exchange goes offline, freezes your account, etc.) - so if you want to hold on to your XRP's for some time, better send them to your own wallet. How about the wallet keys? There are two keys: the public key (wallet address) and the private key (secret key). The wallet address starts with a r and the private key starts with the letter s. The wallet address is generated from the private key. This means you can loose your wallet address (the one starting with r) since you can just re-generate the same address from your private key. The private key is for your eyes only (!!!) - If someone has access to your private key they have access to all the funds stored in the Ripple wallet. Please don't share your private key, please don't store it somewhere in a document on your computer, and never enter it somewhere except if you trust the place you are entering the key. Your wallet address (starting with r) is kind of your "XRP Wallet bank account number". You can send XRP to this wallet. You can check the transactions from your wallet (more below, 'consult'). Your private key (starting with s) is kind of your PIN + Username + Password for online banking: you can access all your funds and send them somewhere. Risky! How to generate a paper wallet There are many places offering to generate your paper wallet, however: some of them can't be trusted. Imagine the website generating the wallet stores the generated values, and waits untill you deposit your XRP: since they have the private key they can steal your funds. I prefer generating a wallet with open source code, so the geeks can audit the source code. Here you can find a wallet generator I trust: https://ihomp.github.io/ripply-paper-wallet/coldwallet-SHA1-cdfbe3260927b6073180a1099f02ef99ce0495e8.html. Security If you want to be sure the generated values aren't stored, you can download the source-code, store it at your computer, unplug your computer from the internet, reboot, generate, print, reboot and plugin the internet again. If you're a geek yourself, you can generate a wallet offline using the nodejs Ripple-Lib code. Here's a sample. How to get XRP into your wallet (deposit) Send XRP to your wallet address (starting with r). Most exchanges offer to withdraw XRP. You can enter your wallet address as the recipient. If you are asked for a destination tag and the address you are sending the XRP to is your own paper wallet, you can leave the _destination tag_ empty or enter a zero (0). The destination tag can only contain numbers, and can be used to distinguish funds entering your wallet. How to check my balance Since the XRP ledger is open to the world, the whole world can check your balance. However: as long as you keep your wallet address to yourself, no one will know the wallet belongs to you. To check your balance, you can use one of the publicly available tools, and enter your wallet address. I like these two: https://bithomp.com/explorer/ https://ripple.com/build/ripple-info-tool/ Of course you can install a wallet on your phone or computer and check your balance with the app; the app can be used to transfer/withdraw your XRP as well. For iOS and Android, give Toast Wallet a spin. NOTE: If you decide to use one of the available wallets, remember you have to enter your private key. Only enter the private key if you trust the app. Remember: if anyone gains control over your private key, they can steal your funds! However: since Toast Wallet is open source, everyone can audit the source code. How to get XRP out of your wallet (transfer/withdraw) To send XRP from your wallet to another wallet address (like the wallet address of an exchange) you need to generate a transaction and sign the transaction with your private key. You can do this with any XRP wallet you trust. If you install wallet software you can enter your private key to allow the wallet software to sign your transaction. If you install Toast Wallet on your iOS or Android device, you can set a PIN code, and then go to: Add wallet Existing wallet Enter the private key in the first field, leave the address field empty (it will be generated from the private key). Enter a description and pick a password. You need the password to confirm transactions for this wallet in Toast Wallet. If you want to use Gatehub, you can access your own wallet: Wallet <+> (Add wallet) Import (enter your Gatehub password) Enter your Secret Key

  3. Hi. If u want to creat your own PaperWallet. Guide -> https://chaos-artonline.com/xrp.php My guide is based on ripple.com ( https://developers.ripple.com/rippleapi-reference.html )
  4. How can I import my existing wallet onto the ledger nano s? note: I do not want to transfer XRP from my existing wallet to a new wallet on the ledger nano S. All help appreciated. I don't want more than one wallet, I just want to access my existing wallet on the ledger nano S.
  5. You can find it here: https://termhn.github.io/ripplewarpwallet RippleWarpWallet is a fork of the original WarpWallet used for making Ripple wallets instead of bitcoin ones. It is a deterministic ripple address generator. You never have to save or store your secret key anywhere. Just pick a really good passphrase - I recommend using Diceware, an online implementation of which you can find here - and never use it for anything else. This is not an original idea. bitaddress.org's brainwallet is the original inspiration, and the original WarpWallet, of course, inspired this Ripple version. The source code is hosted on github. WarpWallet adds two improvements over the traditional brainwallet: (1) WarpWallet uses scrypt to make address generation both memory and time-intensive. And (2) you can "salt" your passphrase with your email address. Though salting is optional, we recommend it. Any attacker of WarpWallet addresses would have to target you individually, rather than netting you in a wider, generic attack. And your email is trivial to remember, so why not? If you're a programmer and want to implement WarpWallet yourself, here is the algorithm used. Ripple-specific functions are part of the ripple-keypairs npm package... s1 = scrypt(key=(passphrase||0x1), salt=(salt||0x1), N=218, r=8, p=1, dkLen=32) s2 = pbkdf2(key=(passphrase||0x2), salt=(salt||0x2), c=216, dkLen=32, prf=HMAC_SHA256) secret = generateSeed(s1 ⊕ s2) keypair = deriveKeypair(secret) address = deriveAddress(keypair.publicKey)
  6. Pointed to from Alec Liu, this paper is a fantastic article that points at the massive wave of fintech pushing against banks right now: http://www.oliverwyman.com/content/dam/oliver-wyman/global/en/2016/feb/BlockChain-In-Capital-Markets.pdf
