      your crypto shouldn't be lost forever

you spent years building your crypto legacy. don't let it be lost to the void.

if something happens to you, the blockchain doesn't care. your family gets nothing, not because of a theft, but because the keys are frozen forever. we ensure they're not.

protect your crypto legacy →

peace of mind for you. a legacy for them.

Deadhand is the safety net for your crypto. We don't hold your funds, we don't know your password, and we can't touch your keys. We just provide the bridge that makes sure your family isn't left empty-handed.

the fail-safe system

We use Shamir’s Secret Sharing, an industry-standard protocol that splits your "emergency access" into three unique pieces. We handle the heavy cryptography; you just keep the keys.

2 shards = full recovery. 1 shard = zero information.

it’s like points on a paper: one point tells you nothing about the line. with two, the path is absolute.

shard a
you keep

shard b
your family holds

shard c
deadhand guards

1. you're always in control: you keep one piece, your family keeps another. you can recover your keys anytime, completely offline, without needing us.

2. we guard the safety net: we guard the third piece. if you ever stop checking in, we release it to your family so they can unlock the legacy you worked to build.

\[ f(x) = S + a_1x + a_2x^2 + \dots + a_{k-1}x^{k-1} \]

no lawyers. no probate. no "trusting" a bank. just automated safety.

self-host: always free. clone the repo and run your own instance.

there's nothing else like this

i spent weeks looking. exchanges, lawyers, multisig, custodial apps, tokenized DAOs, metal plates... all garbage.

exchanges: kyc hell. they'll freeze your family's money for "verification" while the market crashes.
lawyers: they understand houses, not private keys. too slow and too expensive.
multisig: good luck explaining "cosigning" to your mom.
private wealth firms: $6,000/yr for 'white glove' service.

custodial apps: they hold your keys. If they go bankrupt (FTX?), you're a creditor, not an heir.
tokenized daos: if the token crashes, the nodes quit, your sarcophagus stays buried.
metal plates: great against fire, terrible against a $5 wrench.

not just crypto

deadhand works with any secret: GPG keys, SSH keys, password managers, hardware security keys.

GPG keys: protect your signing identity forever
FIDO2 / WebAuthn: back up your hardware security keys
SSH keys: ensure server access doesn't end if you're unavailable
password manager master keys: your 1Password/Bitwarden vault isn't lost

if it's a secret string that unlocks something important, deadhand can protect it.

security

we get hacked

deadhand only touches shard c. it is cryptographically useless without the other pieces.

we go rogue

the protocol is non-custodial by design. reconstruction requires 2 shards; we only have 1.

deadhand shuts down

you always possess shard a and shard b. recovery is possible entirely offline.

man in the middle

all splitting logic executes in your browser. your seed never traverses the network.

code is open source. go read it and ask ai.

no lock-in

we use standard BIP-39 and Shamir's Secret Sharing. if deadhand disappears tomorrow, you can recover your keys using ssss-split on linux or any other standard offline tool. the emergency exit is always open.

social proof

faq

Absolutely not. Deadhand is architected as a non-custodial protocol. We only hold Shard C, which is mathematically insufficient to reconstruct your private key. The recovery process requires two out of three shards; since only you and your beneficiary hold the remaining pieces, we have zero access to your assets.

This is precisely why the protocol exists. You can combine Shard A (which you keep) with Shard B (held by your family) at any time to instantly reconstruct your original 12 or 24-word seed phrase without any assistance from our servers.

No. Your beneficiary only holds Shard B. To recover the seed, they need a second shard. Shard C is held in our secure vault and is only released after our autonomous monitoring confirms 90 days of total inactivity, following multiple failed check-in attempts via your primary contact method.

Deadhand supports any secret that can be represented as a string, including all BIP-39 compliant seed phrases. This makes it universally compatible with Bitcoin, Ethereum, Solana, and thousands of other assets across all major hardware and software wallets.

The protocol is built on open standards. Because we use standard Shamir's Secret Sharing (SSS) and BIP-39 mnemonic logic, you are never locked into our service. If our servers ever went offline, you could use any standard offline SSS utility (like ssss-split on Linux) to combine your shards and recover your assets. Your legacy is protected by math, not a company.

Never. The Deadhand switch is governed by strict, autonomous logic with no manual override capability. This "Hard Logic" ensures that no amount of social engineering can force a premature release of Shard C. The safety of your vault is absolute.

No. We believe in transparent, flat-rate pricing. Whether you are protecting $1,000 or $100,000,000, the protocol cost remains the same. We do not charge percentage-based "success fees" or performance taxes on your inheritance.
