Bitcoin Inheritance Guardian Backup
A multisig wallet needs its descriptor as well as its keys. Lose one key and the descriptor together, and the keys you still hold cannot rebuild the wallet. A 2 of 3 with two keys and no descriptor is locked. The descriptor backup immortalizes an encrypted copy on Bitcoin's time chain. You choose what opens it, as many of the wallet's public keys as it takes to spend, or any one of them.
Your heirs will need to know which wallet this is, how it opens, where each key lives and who to call first. Nobody should learn it before then. The tool encrypts the sensitive part and splits it into guardian bundles for people you choose. A bundle names its own holder, never who else has one, and says how many bundles are needed. Enough of them together open everything, the descriptor backup included. The encrypting happens on your machine and nothing is uploaded.
Not sure what you need? The inheritance quiz takes two minutes and points you at the right option.
One secret, sealed
Bitcoin Inheritance encrypts your secret in the browser. The plaintext never leaves your machine.
N guardian bundles
Each guardian receives one bundle. A bundle holds the full encrypted payload plus one key share.
Any k recover
Bring any threshold of guardians together and their shares rebuild the key and decrypt the secret.
Client-side, offline
The pages are fully self-contained. Save them to disk and run the whole process with no network.
What your heirs need to know
Files alone tell your heirs nothing. Create Bundles asks how the wallet works and where the keys are, in your own words. Both stay sealed inside the encrypted archive, so they open only when enough guardians come together. How the wallet works can also go onto Bitcoin if you ask for it. Where the keys are never does.
Open Create BundlesDescriptor on Bitcoin
For multisig wallets. Lose one key and the descriptor together, and the keys you still hold cannot rebuild the wallet, even when they are enough to sign. Create Bundles encrypts the descriptor in your browser so your own keys open it, and gives you one line of text for a single OP_RETURN output. Public and permanent. The tool is free; publishing costs one chain fee.
Read a descriptor backupBitcoin Inheritance as a service
The tool is free, forever. The service is the practice. A Butler guides your placement session over video: your files, your guardians, your machines. We see screens, never bytes, and we never hold a bundle. Every year, a one-hour drill rehearses the recovery with your guardians so the plan works before it is needed. Offered globally, delivered remotely.
Each Butler sets their own hourly rate, so the prices below are that rate for the length of the session. Change the Butler and the prices change with them.
