How do I use theBillfodl? How do you set it up with your wallet?Each Billfodl package comes with the mainsteel unit or chassis and a set of over 300 character tiles. After you havereceived you 12 or 24 word recovery phrase (otherwise known as a recoveryseed, seed phrase, or mnemonic phrase), you will open your Billfodl and theprovided pack of character tiles and you will spell out the first fourletters of each word and slide them into the main unit. The Billfodl mainunit has labels above each slot so you know which word of your seed goeswhere.I only see support for 96 characters;what if one of my words is more than 4 characters long?Don't worry! You can still store you yourseed securely on Billfodl. The way the recovery seeds work is such that youonly need the first 4 letters of each word in the seed. For example, if yourseed had the words: witch collapse practice feed shame open despair creekroad again ice lease Then you would arrange your tiles to look like this:witc coll prac feed sham open desp cree road agai ice leas If you ever needto recover your private data, you would just input the first four lettersinto any major crypto wallet (MyCelium, Jaxx, Ledger, Trezor, etc).Does Billfodl support all key types?Indeed it does! We only have one product,and it was designed to support all private key types: Hexadecimal,Alpha-Numeric (Wallet Import Format), and 12, 18, and 24 word seed phrases.We designed it so there was no confusion for our clients. It doesn't matterwhat kind of key or password you are storing.Is Billfodl better than a paper wallet?One of the primary drawbacks of the paperwallet is its poor longevity. Ink can run in humidity, the paper dissolves inwater, and in the longer term, paper degrades. Because of the high qualitybuild materials of the Billfodl, you can be sure that your private data andcrypto keys are safe from both the elements and time itself. Additionally,paper wallets are produced by third party agents, so until you go to recoveryour coins, you never really know they are safe to begin with. Billfodleliminates this weak point in security by allowing you to create the offlinestorage on your own without trusting a third party not to steal your coins.What happens if my Billfodl is lost orstolen?If your Billfodl is lost or stolen,IMMEDIATELY move all of your crypto to a new address which utilizes acompletely different Seed or Private Key. If using Billfodl to store SeedWords, we recommend you use a passphrase (sometimes called a "25th word") sothat if someone finds your Billfodl, you still have some protection (see BestPractices for more information). This can be done on most hardware wallets. How do I recover data protected byBillfodl?To retrieve them, simply open any bitcoinwallet which supports Seed Phrase import, such as another Trezor or Ledger,GreenAddress, or Mycelium among many others. Again, there is NO RUSH. Yourfunds are safe on the blockchain. Please take your time to research how to dothis with your preferred wallet. While the exact process differs in everywallet, most have a feature to input Seed Words. As always if you have anyquestions, we are always here to help at
[email protected] I use Billfodl instead of a Ledger orTrezor hardware wallet?TL;DR - Please don’t. While you could useBillfodl instead of a hardware wallet by creating new cold wallets andloading the private keys into Billfodl, in practice this is not the best wayto use Billfodl, and if you transacted with any frequency, this method wouldbecome very cumbersome. Instead, the Billfodl is meant to complement yourhardware wallet by enabling you to store your Seed Words in a way that is asindestructible and safe from user-error as we could conceive of.
