You die or stop responding.
2021 · Mircea Popescu drowned. Up to $1B in BTC, keys unknown.
Dead man's switch · Built for Solana Seeker
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
Your Seed Vault blocks malware. It does nothing if:
2021 · Mircea Popescu drowned. Up to $1B in BTC, keys unknown.
2025 · A Ledger co-founder was kidnapped for a crypto ransom.
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.

How it works
Four screens, from plan to payout. Running today on devnet.
Set who receives; the app handles the rest.
The vault locks on-chain. Withdraw shows a fake timeout.
Checking in resets the timer.
No check-in, and the heir accounts receive.
One skull, four moods
A sped-up demo. Check in to stay alive, or let the clock run and watch each stage play out.
Checked in on time. Nothing moves.
Silence has started. The next release tier is counting down.
A tier is due. Funds go to the heir.
Every tier has paid out. Rest easy.
Why now
Seed Vault keys never leave the secure chip.
72 physical attacks on crypto holders in 2025, up 75% on 2024.
Cloak is live on Solana mainnet; NEAR Intents delivers shielded ZEC.
Kora pays the ~0.000005 SOL fee, so the check-in key never needs SOL: nothing to top up, nothing to drain.

FAQ
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.
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.
Nothing. Kora sponsors the network fee, so the check-in key never needs SOL.
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.
Any Solana wallet, or someone without one through a Cloak claim code. Each plan can have up to 8 tiers, paid in order.
The alpha is live on devnet. The target is a Solana dApp Store release in Q2 2027, after an external audit.
