we solve

01
Specify one to four addresses where your assets will be recovered if you something goes wrong.
02
Deploy your backup smart contract using MetaMask or WalletConnect. You won't have to share your mnemonic, and Tezoro won't have access to your assets at any point in time.
03
Now the smart contract can withdraw assets from your address and transfer them to beneficiaries, even if you lose access to your wallet or die. It is impossible to replace beneficiary addresses, which guarantees the safety of your assets.

SECURITY
Why should I trust you?
  • 1.
    You don't need to. Tezoro does not have access to your assets or mnemonic at any point of time.
  • 2.
    We deploy a separate smart contract for each customer. This smart contract cannot be customized, so all the settings you chose are protected by the blockchain.
  • 3.
    The source code of our backup smart contract is open and verified on Etherscan. You can check it out here.
  • 4.
    Tezoro smart contract has been audited by CertiK.
Do I have to share my seed phrase to create a backup?
No
Why is it impossible to hack my backup?
It’s impossible to hack a smart contract due to its nature: it is either executed in the form in which it was created, or not executed at all.
Does Tezoro have access to my funds?
No, Tezoro does not have access to your funds at any point in time. The only thing that has access to your assets is a smart contract that cannot be hacked.
Is Tezoro anonymous?
Yes, Tezoro is an anonymous service. You do not need to go through KYC, link a credit card, or do anything else to verify your identity.
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.

TECHNOLOGY
Why is Tezoro better than competitors and abstract wallets?

    Tezoro is non-custodial: you don't have to share your assets or wallet access keys, either when creating a backup or when withdrawing and transferring your assets to a backup address.
  • 3.
    Tezoro is unhackable: your backup is a smart contract that is impossible to hack because of its nature.
  • 4.
    Automation: Tezoro provides several options for the automated execution of your backup.
  • 5.
    Decentralization: a backup created with Tezoro can be executed even if Tezoro ceases to exist: you can add two workers who can run your backup directly through Etherscan.
  • 6.
    Unlike competitors, by creating a backup and will with Tezoro, you continue to keep your crypto in your wallet and use it without any restrictions.
  • 7.
    The backup amount can be higher than your current balance.
Do my assets become locked after I create a backup?
No, you can continue to use your crypto as before. After creating a backup, you keep access to your assets without any restrictions.
Is Tezoro a no-code solution?
Yes, Tezoro is a 100% no-code solution. You do not need to write any code, just fill in a few inputs on the website and confirm the deployment of your backup smart contract on the blockchain via your MetaMask account.
What is the backup execution process?
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 I don’t have enough funds on my address to pay for the gas to execute my backup?
No worries, it’s on us. Tezoro will pay the gas fee for you to launch your backup.
