Void
Inheritance
Protocol.

A quantum-resistant dead man's switch for your VOID. Your keys never leave this page. No server. No third party. No trust required.

⚠️

This tool runs entirely in your browser. Nothing is ever sent to a server. Your seed phrase or private key is used only to sign transactions locally and is never stored or transmitted. Keep your inheritance package file safe — it is the only way your heirs can claim your VOID.

Setup
Check-in
Heir Broadcast
Verify Package
Step 1 of 3
Your wallet

Choose how you want to authenticate. Both methods are equally secure — your key never leaves this page.

🌱
Web Wallet
I have a BIP39 seed phrase from wallet.void-coin.net
🔑
Qt / Desktop Wallet
I have a private key (WIF) from VoidCoin-Qt or CLI
Your seed phrase from wallet.void-coin.net. Never share this with anyone.
This is the address holding the VOID you want to protect.
Leave a small amount for transaction fees (0.001 VOID recommended).
Step 2 of 3
Your heirs

Add one or more heir addresses and specify what percentage each receives. Percentages must total 100%.

Step 3 of 3
Check-in interval

How long after your last check-in should your heirs be able to claim? If you don't check in within this window, the transactions become broadcastable.

Extend your timelock

Load your existing package file and enter your seed phrase to generate a new package with an extended expiry. Share the new package with your heirs — the old one becomes invalid once the new transactions are broadcast.

For the heir

If you have received this tool and a package file from someone who has passed away or become incapacitated, follow these steps:

  1. Load the inheritance package file below
  2. Verify the package details — source address, your address, amount
  3. Wait until the timelock has expired (the broadcast button will activate automatically)
  4. Click "Broadcast transaction" — the VOID will arrive in your wallet
Verify a package

Load a package file to inspect its contents without broadcasting anything. Use this to confirm your package is valid and contains the correct heir addresses and amounts.
