Honest answersto the hardest questions.

You begin recovery from any device. The trusted people you named at setup (your guardians) confirm it's really you with their own wallet signatures. A seven-day window opens. You can cancel it at any point, from anywhere, for any reason.

If nothing was cancelled, your vault now answers to your new wallet. Heirs, shares, and standing orders are preserved exactly. Your balances don't move; they were always in the vault, not in the wallet.

Your vault keeps working. The smart contract sits on the blockchain. It doesn't depend on our servers. Heartbeat, stewards, standing orders, claim flow: all enforced by the contract, not by us.

We mirror recovery instructions to IPFS and our public GitHub. If we vanished, your family could still inherit from any wallet on any chain.

A single signature is never enough. To move funds out of your vault, a quorum of your named heirs must sign together. After they do, there's a 20-minute commit-reveal cool-off before anything moves. If you suspect something, you pause. The vault freezes for up to seven days.

A hacker who takes one wallet (yours, an heir's, a steward's) can do nothing alone. The system was designed assuming any single key could be compromised. The plan survives that.

Yes. The vault is a smart contract you deploy from your own wallet. Only that wallet (and the rules you wrote) can change anything. We have no admin key, no upgrade backdoor, no master switch. The OpenZeppelin audit and our 51 Halmos formal proofs verify exactly this.

Seven EVM chains today (Ethereum, Base, Arbitrum, Polygon, BSC, Avalanche, Hyperliquid), plus Bitcoin (Taproot multisig), Tron, and Solana. You can have one vault per chain or vaults on every chain. The rules are yours, the plan is the same.

On EVM chains: native (ETH/etc), any ERC-20, any ERC-721 NFT, and any AAVE-supplied position. On Bitcoin: native BTC. On Tron: native TRX and TRC-20 tokens. On Solana: SOL and SPL tokens. We don't restrict which tokens you can hold. Your vault, your assets.

No. The contracts are permissionless. Our concierge service is opt-in, and we ask only for the information you offer. You don't need an email to use the vault, though we recommend at least one notification channel so you don't miss a heartbeat reminder.

A flat monthly subscription, regardless of how much you protect. The contract itself only charges network fees, paid by whoever initiates an action (you, an heir, a steward). We don't take a percentage of your assets, and we don't take a cut of any transfer.

Yes, optionally. You can supply tokens to AAVE V3 from inside the vault, earn yield, and withdraw whenever you choose. The yield accrues to the vault, so heirs benefit too. This is opt-in and managed entirely by you.

No. HeirVault is a self-custodial inheritance layer for your crypto holdings. It does not replace a will, a trust, a tax advisor, or a conversation with your lawyer about how your jurisdiction treats digital assets. It does, however, replace the seed-phrase-on-paper problem.

We don't have any. We can comply with a court order to stop selling you our subscription service, but we cannot move your funds, change your rules, or hand over keys we never had. Your vault is yours, on chain.
