The switch is armed.
0.2 SOL enters the vault. An heir is named. The threshold is set at two hours.
A dead man's switch on Solana. Set a heartbeat, name an heir — if you fall silent past the threshold, the estate settles itself.
A wallet on mainnet ran this full course. The chain kept the minutes; this is the deed it wrote.
0.2 SOL enters the vault. An heir is named. The threshold is set at two hours.
Each signature resets the silence. The estate stays with its owner.
The heartbeats stop. Two hours of silence pass, witnessed by the chain alone.
Past the threshold, one signature settles the estate. The vault empties into the heir's wallet.
Armed on mainnet with a 24-hour threshold. Its owner sends a heartbeat twice a day; the quiet in between is measured below, live.
A real switch from any wallet. Pulse whenever you like; disarm any time and the vault returns to you in full.
Any Solana wallet. Nothing moves until you sign the deed.
One signature writes the rule into the chain. Your heartbeat starts counting.
A switch is one account: owner, heir, threshold, and the timestamp of the last heartbeat. Pulse rewrites the timestamp; inherit only executes if the clock reads more silence than the threshold allows. There is no other path to the funds.
The vault is a program address derived from your switch. No company holds it, no multisig votes on it, and the heir learns nothing until the silence runs out.
SOL estates only, one heir per switch, one rule per wallet. Token estates and split inheritance follow in the next chapter.
SPL tokens, split inheritance across several heirs, a verified build badge, and an SDK for wallets that want to offer this natively.
