Frag-ment, in real life.

From single-seed backup to inheritance and multi-wallet setups. Concrete examples of how people secure and transmit seed phrases with Frag-ment.

Single seed

Protect a single seed across your home.

You hold one wallet. One seed. Currently on a piece of paper in a drawer. With Frag-ment, fragment it into 3 fragments with a 2-of-3 scheme:

  • NFC card (in your home safe)
  • Paper backup (with your partner's belongings)
  • Mobile vault (on your phone)

Any 2 reconstruct the seed. Losing one means nothing.

This is one approach. The threshold and supports are yours to choose.

Multi-wallet

Manage multiple seeds without losing your mind.

You hold 5 wallets (DeFi, cold storage, NFT, trading, treasury). Each has a different risk profile, so each gets its own setup:

  • Cold storage seed (3-of-5 scheme, PC vault + NFC card + paper backup, kept rarely accessed)
  • Active trading seed ( 2-of-3 scheme, PC vault + mobile vault + online vault, accessible quickly )
  • Long-term holdings ( 5-of-7 scheme, paper + online vault + NFC + notary across distant locations )

Different stakes, different setups. Same engine.

This is one approach. The threshold and supports are yours to choose.

Inheritance

Plan the transmission of your assets, on your terms.

You want your heirs to access your crypto if something happens to you, but not before, and not without rules. With a 3-of-5 scheme:

  • NFC card (kept by you, in your safe)
  • Paper backup (held by your partner)
  • Sealed envelope (deposited with your notary)
  • Online vault (accessible to your executor with a delay condition)
  • Metal backup (in a bank safety deposit box)

No single party can act alone. Three signatories must agree to reconstruct.

This is one approach. The threshold and supports are yours to choose.

Trust circles

When trust isn't flat.

Real-world trust isn't binary. You may trust your family fully, your professional advisors partially, and yourself for daily access. Frag-ment's group system lets you require 2 of 3 family fragments AND 1 of 2 professional fragments to reconstruct your seed.

Family group (2-of-3 required)
  • NFC card (held by your partner)
  • Paper backup (with a trusted child)
  • Mobile vault (on a family device)
Professional group (1-of-2 required)
  • Sealed fragment (with your notary)
  • Online vault (in your wealth advisor's care)

Both group rules must be satisfied. Different rules for different circles, all enforced by mathematics.

This is one approach. The threshold and supports are yours to choose.

And many setups we haven't imagined yet.

These are the scenarios we see most often. But Frag-ment is a general-purpose tool: its rules are mathematical, not prescriptive. Whatever your situation, you design the threshold, the supports, and the trust circles that fit it.

If you're using or plan to use Frag-ment in a way we haven't thought of, we'd love to hear about it.
