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, always. Vault is fully non-custodial. Your assets live in a smart contract on-chain that only you can deposit into and only your heirs can withdraw from, under the rules you define. We never hold your keys or have access to your funds.
HeirVault 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. On Tron you can store TRX and TRC-20 tokens (like USDT). On Solana you can store SOL and SPL tokens. Bitcoin vaults support native BTC via multisig. 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.
A Guardian is a trusted party you appoint who can extend the check-in deadline by up to 90 days per active claim, within a 180-day lifetime cap — useful if you're traveling or temporarily unable to check in. Guardians cannot withdraw, transfer, or modify assets in any way.
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).
HeirVault is truly multi-chain. We support all major EVM networks (Ethereum, Base, Arbitrum, Polygon, BNB Chain, Avalanche), Tron, Solana, and Bitcoin. EVM chains share one Solidity codebase; Tron, Solana, and Bitcoin use native implementations with explicit chain-specific claim, guardian, and relay behavior.
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. Your vault is a smart contract on-chain that works independently of our service. You can interact with it directly through any block explorer (like Etherscan) using the "Write Contract" feature — no coding required. EVM owners have an owner-only instant recovery path through emergencyRecovery, and heirs can complete the full claim flow. See our Recovery Guide for step-by-step instructions.
