The problem
1500 BTC is lost daily due to loss of access to wallets.
How does Tezoro solve it?
Step 1
Prepare a backup
Create a smart contract that can recover your crypto if you lose access to your wallet or die.
Step 2
Use your crypto as before
After creating a backup, you keep access to your assets without any restrictions. You can spend, transfer or withdraw it.
Step 3
Ooops...
You have irretrievably lost access to your wallet or died. Is it possible to withdraw funds from your wallet?
Step 4
No worries 👌
If you have prepared a backup with Tezoro, you have nothing to worry about. Your crypto can be recovered. How?
You, executors, or one of the automated triggers launches your backup → 30 days pass during which it is possible to cancel the execution → your crypto withdraws from your wallet to the smart contract → your crypto transfers to the receiver's address.

What happens if my Tezoro account is hacked?
Safety is our #1 priority. We take the highest measures to protect our infrastructure.
However, in the unlikely event that your account is hacked, the only thing that can happen is that a hacker can transfer your assets to your backup address. It is virtually impossible to withdraw assets to any other address rather than the one you provided as your backup address. This security is guaranteed by the nature of the blockchain.
Thus, there is no reason for an attacker to try to hack your Tezoro account since it is entirely impossible to transfer your assets to any address other than your backup address. This security is guaranteed by the nature of the blockchain.
Moreover, any backup smart contract has a 30-day buffer. During this period, we will send you several email notifications so that you can easily cancel this process.
How much does the backup smart contract service cost?
The service fee is 0.09 ETH per backup. Also, there is a transaction fee for deploying a smart contract, which is calculated based on network busyness.
