Frequently Asked
Everything you need to know about protecting your digital assets — from dead-man's switch cadence to cross-border heir flows.
That is exactly the problem Vault solves. Once you miss your check-in deadline, your designated heirs can initiate a claim. After a configurable grace period and the required number of heir signatures, each heir can withdraw their on-chain share — no seed phrases or third parties needed.
No. The claim process can only begin after the dead man's switch expires — meaning you have missed your scheduled check-in. As long as you check in on time, nobody can touch your assets. Even after the switch triggers, a grace period gives you time to intervene.
You do. HeirVault does not hold custody keys or sign transfers from your vault. EVM vault logic runs through chain-native contracts, and Bitcoin vaults use native BTC scripts and PSBT signing. Direct deposits may be possible depending on the asset and chain, but withdrawals follow the vault's owner/heir rules.
HeirVault Open Beta supports multiple blockchains. On EVM chains (Ethereum, Base, Arbitrum, Polygon, BSC, Avalanche) you can deposit native ETH, any ERC-20 token (USDC, WETH, DAI, etc.), and ERC-721 NFTs. Bitcoin vaults support native BTC via multisig. Tron and Solana are available in beta. After a valid claim, heirs withdraw proportional shares based on heir shares.
No. Vault uses a pull-based withdrawal pattern. After a claim is executed, each heir withdraws their share independently. If one heir's transaction fails (e.g. their wallet rejects ETH), it has zero impact on the others.
On EVM vaults, a Guardian is a trusted party who can extend the check-in deadline by up to 90 days per active claim, within a 180-day lifetime cap, and cancel a scheduled emergency recovery during its timelock. Guardians cannot withdraw, transfer, or modify assets. Bitcoin guardians are a different co-signer trust role.
You set a threshold — for example, 2-of-3 heirs must sign before a claim can be executed. This prevents any single heir from unilaterally accessing the vault. The threshold is configurable from 1 to N (total number of heirs).
Open Beta supports major EVM networks (Ethereum, Base, Arbitrum, Polygon, BNB Chain, Avalanche) and Bitcoin. EVM chains share one Solidity codebase; Bitcoin uses native scripts and PSBT signing. Tron and Solana are available in beta.
Yes. As the vault owner, you can update heirs and their shares, change the required signature threshold, adjust the check-in interval, and add or remove guardians — all while the vault is active.
Yes, but the direct path is chain-specific. EVM owners can use the owner-only instant recovery path through emergencyRecovery(to), while owners and heirs can use block explorers or wallets to call functions such as commitExecuteClaim, executeClaim, and withdrawals. Bitcoin uses native tools and PSBT flows. See the Recovery Guide for step-by-step instructions.
