The Solution

Your own backup address — a second chance built into the blockchain

Self-Heir Pattern
Designate your own backup wallet as the sole heir. You're not trusting anyone else — you're trusting your future self with an alternative key.
Dead Man's Switch as Recovery Trigger
Set a check-in interval. If you can't check in (because you lost your primary wallet), the recovery process begins. Claim from your backup address.
No Seed Phrases Needed
Traditional recovery depends on memorizing or storing seed phrases. With HeirVault, your backup wallet IS your recovery mechanism — simple and robust.
Works Across Chains
Set up recovery vaults on Ethereum, Bitcoin, Base, Polygon, Tron, Solana, and other live deployment chains. Protect all your assets with one backup strategy.

How It Works

Set up your safety net in minutes

01
Create a Vault, Name Yourself as Heir
Connect your primary wallet, deploy a vault, and set your backup wallet address as the sole heir with 100% share.
02
Deposit Assets You Want to Protect
Move tokens, ETH, or BTC into the vault. You retain full control and can withdraw anytime from your primary wallet.
03
Check In Regularly
Confirm activity periodically. If you ever lose your primary wallet, simply wait for the check-in to expire and claim from your backup address.

Answers from the contract — not the sales deck.

Seed phrases can be lost, stolen, or destroyed. A backup wallet is a living, independent key that you control. Even if your primary device is lost, stolen, or damaged, your backup wallet on a different device or hardware wallet gives you access.

You can add guardian oversight for extra security. Guardians can extend the claim deadline, giving you time to react. For maximum security, use a hardware wallet for your backup address and store it separately.

Your assets are in the vault smart contract. You can withdraw them anytime with your primary wallet. Think of the vault as a safe — you have the key, and you've hidden a spare.

On EVM, Tron, and Solana vaults, a missed check-in lets the backup wallet initiate a claim; that claim starts the grace-period deadline, and a check-in cancels the claim before execution. If you've set up a guardian, they can also extend the claim deadline on your behalf.

Yes. Bitcoin vaults use native multisig scripts with OP_CSV timelocks. Your backup address can claim BTC only after every confirmed UTXO satisfies the configured timelock plus grace blocks, using the same self-recovery pattern.

Never Lose Access Again

Set up your backup recovery in under 5 minutes. No seed phrases. No third parties. Just your own backup wallet.
