How do I use the Billfodl? How do you set it up with your wallet? Each Billfodl package comes with the main steel unit or chassis and a set of over 300 character tiles. After you have received you 12 or 24 word recovery phrase (otherwise known as a recovery seed, seed phrase, or mnemonic phrase), you will open your Billfodl and the provided pack of character tiles and you will spell out the first four letters of each word and slide them into the main unit. The Billfodl main unit has labels above each slot so you know which word of your seed goes where. 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 your seed securely on Billfodl. The way the recovery seeds work is such that you only need the first 4 letters of each word in the seed. For example, if your seed had the words: witch collapse practice feed shame open despair creek road 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 need to recover your private data, you would just input the first four letters into 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 matter what kind of key or password you are storing. Is Billfodl better than a paper wallet? One of the primary drawbacks of the paper wallet is its poor longevity. Ink can run in humidity, the paper dissolves in water, and in the longer term, paper degrades. Because of the high quality build materials of the Billfodl, you can be sure that your private data and crypto keys are safe from both the elements and time itself. Additionally, paper wallets are produced by third party agents, so until you go to recover your coins, you never really know they are safe to begin with. Billfodl eliminates this weak point in security by allowing you to create the offline storage on your own without trusting a third party not to steal your coins. What happens if my Billfodl is lost or stolen? If your Billfodl is lost or stolen, IMMEDIATELY move all of your crypto to a new address which utilizes a completely different Seed or Private Key. If using Billfodl to store Seed Words, we recommend you use a passphrase (sometimes called a “25th word”) so that if someone finds your Billfodl, you still have some protection (see Best Practices for more information). This can be done on most hardware wallets.   How do I recover data protected by Billfodl? To retrieve them, simply open any bitcoin wallet which supports Seed Phrase import, such as another Trezor or Ledger, GreenAddress, or Mycelium among many others. Again, there is NO RUSH. Your funds are safe on the blockchain. Please take your time to research how to do this with your preferred wallet. While the exact process differs in every wallet, most have a feature to input Seed Words. As always if you have any questions, we are always here to help at [email protected]. Can I use Billfodl instead of a Ledger or Trezor hardware wallet? TL;DR - Please don’t. While you could use Billfodl instead of a hardware wallet by creating new cold wallets and loading the private keys into Billfodl, in practice this is not the best way to use Billfodl, and if you transacted with any frequency, this method would become very cumbersome. Instead, the Billfodl is meant to complement your hardware wallet by enabling you to store your Seed Words in a way that is as indestructible and safe from user-error as we could conceive of.
