Bitcoin Legacy
A dead-man's switch built from Bitcoin itself — pre-signed, time-locked transactions we physically cannot spend, alter, or lose.
You did everything right — hardware wallets, steel backups, keys that never touched the internet. But if something happens to you, can your spouse run a signing ceremony? Will your kids find the passphrase? Self-custody dies with the custodian. Bitcoin Legacy is the bridge: your security stays absolute, and your heirs need zero technical skill.
In your own wallet, you sign a transaction paying your heirs — time-locked months into the future. Your keys never leave your possession. We never see them.
We store the signed transaction and watch the chain. A simple "I'm alive" check-in — one click, no keys — keeps us reminding you to roll the date forward as life goes on.
If the lock expires, the transaction broadcasts automatically and the coins move to your heirs — no keys, no lawyers, no exchange accounts. They don't even need to know what a private key is.
Most custody products ask for trust. Bitcoin Legacy is built so that trust is mathematically unnecessary — the protocol enforces our restraint, not our promises.
The transaction carries an nLockTime — a rule enforced by every node on the Bitcoin network. Until that date, the transaction is invalid for everyone, including us. Broadcasting it early is rejected by consensus itself.
The transaction is signed by your private keys — which we never have. Changing the amount, the recipients, or the date by even one byte destroys the signature. What you signed is the only thing that can ever happen.
Your coins never move to us. They stay in your cold storage, untouched, until the day the timelock opens. Change your mind? Spend your coins normally — that instantly and permanently voids the inheritance transaction.
Multisig, passphrases, geographically-split steel plates — your setup is a fortress. Bitcoin Legacy doesn't weaken it by a single bit. Everything we hold is information that's useless to a thief and priceless to your family.
Your beneficiaries receive bitcoin at addresses you chose — a hardware wallet you set up for them, their own wallet, anything. They never run software, never sign anything, never learn a seed phrase. Inheritance arrives like a wire transfer, not a cryptography exam.
