More on recovery seeds: 

  • A recovery seed is a list of words in a specific order used as a backup for hardware and software wallets. It is a very large random number made easy to read.
  • Wallets use a seed to generate unique private keys. The same seed always gives the same private keys.
  • If the wallet has a problem, the seed is needed to recover it. Without it, the wallet cannot be recovered.
  • “Seed”, “recovery seed”, “mnemonic seed” or “master seed” are synonyms.

More on protection against loss & theft: 

  • You need at least 3 HODLRs to split your seed amongst all of them and protect it against loss and theft.
  •  With such security scheme, each HODLR holds a share. You need more than one share to reveal the seed. But if someone finds one of your HODLRs, your seed remains invisible and you still have the other shares to recover it.
  • There are two ways to split a seed in multiple shares
    • Use a SLIP39 Shamir Secret Sharing compatible hardware wallet. It will generate all the shares automatically.
    • Split a 24 words BIP39 seed manually. It is very easy to do with the Split 2-of-3 Recovery Scheme Sheet included in the box.

HODLR Disks: Physical security

  • HODLR Disks is 100% made of 316L marine grade stainless-steel. For an homogenous high temperature resistance, every component is made of the same material.
  • When it is closed, your HODLR becomes a compact and extremely robust stainless steel monobloc and your seed words are enclosed in a thick protective shell.

How does it work

HODLR Swiss has designed step-by-step protocols for users to follow and ensure security. The platform encourages to schedule a minimum of 1 hour to prepare their respective HODLRs. Moreover, they also urge users to ensure that there are no humans, cameras, or visual witnesses of you when you engrave your seeds onto the HODLR disks. The platform also advises not to read out your seed words out loud to ensure maximum security.

The process is relatively simple; users get their mnemonic recovery seeds from their hardware wallets to their HODLR. Users can upgrade from their paper backup to their holders or recover from their HODLRs on their hardware wallets.

To use their HODLR disks, users have to simply open their HODLR by unscrewing and detaching the top lid. Pre-mark their seed with a permanent marker so if they were to make mistakes, they can use alcohol or acetone to erase. After they’ve marked the correct terms, they can punch their seeds onto each of the 24 disks. After they’ve punched in their seeds, Users can simply seal their HODLRs and store them in a safe place.

HODLR Swiss urges users to keep their HODLR disks private in a safe and discrete location. The HODLR Disk has a magnet included, which users can use to store in creative places. Moreover, the manufacturers also advise keeping their HODLRs away from any camera on your phones, laptops, computers, or recorders.
