The Solution

Programmable inheritance that works without trust or intermediaries

Dead Man's Switch
Set a check-in interval (1 to 365 days). If you miss it, heirs can begin the claim process. As long as you check in, nobody can touch your assets.
Multisig Claims
Require M-of-N heir signatures to withdraw. No single heir can act alone. Configurable from 1-of-1 to 3-of-5 and beyond.
Guardian Oversight
Appoint trusted guardians who can extend the claim deadline — adding a human safety layer against false triggers or premature claims.
Multi-Chain Support
Protect assets across Ethereum, Bitcoin, Base, Arbitrum, Polygon, BSC, Avalanche, Tron, and Solana — all from one dashboard.

How It Works

Three steps to secure your legacy

01
Create a Vault
Connect your wallet, choose your chain, and deploy a non-custodial smart contract vault. Set your check-in interval, heir addresses, share percentages, and multisig threshold.
02
Deposit Assets
Transfer ETH, tokens, NFTs, or BTC into your vault. Assets remain fully under your control — you can withdraw or modify settings anytime.
03
Check In Periodically
Confirm you're active by checking in before your deadline. If you ever stop checking in, your heirs can claim their shares after the grace period.

Answers from the contract — not the sales deck.

If you miss your check-in deadline, the dead man's switch activates and your heirs can initiate a claim. Claim initiation starts the configurable grace-period deadline; once that deadline passes and the required number of heirs sign (multisig), each heir can withdraw their designated share. The entire process is automated and on-chain — no lawyers or intermediaries needed.

No. The claim process only begins after you miss your check-in. As long as you check in on time, nobody can touch your assets. Even after the switch triggers, guardians can extend the deadline to prevent false claims.

They need a basic wallet (like MetaMask) to receive funds. HeirVault provides step-by-step claim instructions. The process is as simple as connecting a wallet and signing a transaction — no seed phrases or private key management required.

You can update heir addresses, share percentages, multisig threshold, and check-in intervals while your vault is active. Heir, share, and signature-threshold updates are scheduled first and become executable after the on-chain timelock; check-in interval changes execute once the owner transaction confirms.

HeirVault is a smart contract tool, not a legal document. It automates the technical transfer of on-chain assets. We recommend using it alongside traditional estate planning for complete coverage. Our Legal Kit provides templates to help bridge the gap.
