Dead man's switch · Built for Solana Seeker

Don’t take your crypto to the grave.

Deadman releases your SOL and USDC to your heirs if you go silent, and locks your vault if someone forces you to send. One fingerprint resets the clock.

The problem

Self-custody has one point of failure: you.

Your Seed Vault blocks malware. It does nothing if:

Silence

You die or stop responding.

2021 · Mircea Popescu drowned. Up to $1B in BTC, keys unknown.

Coercion

Someone forces you to send.

2025 · A Ledger co-founder was kidnapped for a crypto ransom.

Loss

Your phone and keys are gone.

2013 · 8,000 BTC thrown out with a hard drive. Never recovered.

Today’s wallets are all or nothing. Lose the keys, lose the money.

Alive

Checked in on time. Nothing moves.

Missed a check-in

Silence has started. The next release tier is counting down.

Silent past a release tier

A tier is due. Funds go to the heir.

Plan fully released

Every tier has paid out. Rest easy.

Why now

Phones are the new wallet.

A hardware vault in every Seeker

Seed Vault keys never leave the secure chip.

Wrench attacks are rising

72 physical attacks on crypto holders in 2025, up 75% on 2024.

Private send works on mobile

Cloak is live on Solana mainnet; NEAR Intents delivers shielded ZEC.

Kora

Check-ins cost the user 0 SOL

Kora pays the ~0.000005 SOL fee, so the check-in key never needs SOL: nothing to top up, nothing to drain.

FAQ

Questions nobody likes asking.

What is a dead man's switch?+

A mechanism that acts when you stop responding. In Deadman you check in with your fingerprint. If you stop, your release plans pay your heirs, tier by tier.

What does the coercion PIN do?+

If someone forces you to withdraw, enter the coercion PIN. The vault locks on-chain without a sound and the withdrawal shows a fake timeout. Nothing moves.

How much does a check-in cost?+

Nothing. Kora sponsors the network fee, so the check-in key never needs SOL.

What does Deadman charge?+

Only when a tier is released: 2% on the Solana rail, 3% on private channels. Or the optional monthly plan of 10 USDC every 30 days with a 0% fee.

Who can receive the funds?+

Any Solana wallet, or someone without one through a Cloak claim code. Each plan can have up to 8 tiers, paid in order.

When is mainnet?+

The alpha is live on devnet. The target is a Solana dApp Store release in Q2 2027, after an external audit.

Your keys die with you.
Your crypto doesn’t.
