  • What is a Private Key Shard?

    Generally, private key sharding is the process of dividing a single complete private key into several parts, each of which is a private key shard. This overcomes the concern of asset loss due to the loss or theft of an entire private key by a large extent. Safeheron private key sharding involves using the MPC algorithm to generate key shards before constructing a wallet, and then using the MPC algorithm to compute the signature when transacting. In contrast to generic private key sharding, the MPC algorithm generates multiple key shards and the original private key never appears during the entire process, resulting in enhanced security.

  • Which tokens are supported by Safeheron?

    Safeheron supports 11 native coins such as BTC and ETH, as well as hundreds of tokens. Our Web3 wallet is compatible across all EVM chains as well non-EVM chains such as Solana and NEAR which will soon be available. More

  • What distinguishes Safeheron from a MultiSig contract?

    Safeheron's MPC signature algorithm implements ECDSA, EdDSA, and BLS signature algorithms, covering more than 99% of public blockchains. However, the MultiSig contract is restricted to certain EVM chains and incurs a higher gas fee. Safeheron MPC MultiSig, on the other hand, is more secure and effective while less expensive than a typical MultiSig contract.

  • Is there a role with the highest permission in multi-people management?

    Once the wallet is initialized, admins have the same permission that multiple people will jointly make important decisions in the manner of threshold signature set in the management mode.

  • What is MPC and why should I use it?

    Secure Multi-Party Computation, or MPC for short, is also known as SMPC. Learn more about it on our MPC 101. MPC ensures that you can use it while remaining invisible throughout the entire process, from private key generation to usage and storage. Safeheron utilizes MPC to transform a single private key into distributed private key shards, effectively eliminating the risk of a single point of failure of a private key, while allowing multiple individuals on a team to co-manage assets.

  • What is TEE and why should I use it?

    TEE stands for Trusted Execution Environment. More information can be found in Intel SGX Trusted Execution Technology. Sensitive data is secured by TEE with hardware isolation, which protects it from external attacks and sniffing attempts. Safeheron uses TEE to store users' data, transaction policies as well as other sensitive and important information. This help ensures the security of users' data on the hardware.


  • What’s Safeheron’s security model?

    When using MPC to generate private key shards, the original private key never appears from generation to signing transactions. Storage and use of private key shards are all in TEE, ensuring no improper data access occurs even if hackers manage to hijack the server. Furthermore, Safeheron's unique offline public & private key exchange mechanism prevents man-in-the-middle attacks on private key shard generation and transmission.

  • If the email gets compromised, how do I make sure that the assets are safe?

    Safeheron provides enterprise-level security. When using a new/abnormal device to log in, no wallet data can be accessed, and this device must be confirmed by the team creator. That is, even if a user's email account is compromised, the hacker still does not have access to the funds, let alone be able to steal them.

  • Is Safeheron MPC wallet safer than a hardware wallet?

    With hardware wallets, there is a risk associated with a single point of failure on the private key. On the other hand, Safeheron uses MPC technology which utilises decentralised key shards. The private key is not visible at any point of time making it exponentially harder for the private key to be compromised. In addition, Safeheron employs the Trusted Execution Environment (TEE) to assure the security of the key shards and code execution. Safeheron’s multi-party and multi-cloud deployment further minimise the risk of a single point of failure.

  • What if Safeheron goes bankrupt?

    Safeheron is a decentralized MPC MultiSig solution provider in which users own all private key shards from the beginning. As a result, in the unlikely event Safeheron goes bankrupt, users can still use the offline private key recovery tool to recover the original private key along with all key shards. Users can import the original private key into any decentralized wallet and gain access to their funds again.

  • What will happen after recovering the original private key?

    Once the plaintext of the original private key is revealed, Safeheron will assume that the assets are in jeopardy, giving us the authority to halt all movements until further confirmation is received. For security reason, we recommend to only recover the wallet's private key at the end of your service with Safeheron.

  • Is your code open-source and has it been security audited?

    Yes the code is open-source. Our code has been audited by SlowMist, a reputable leader in the cybersecurity industry while the MPC algorithm has been audited by the renowned security firm, Kudelski Security.

  • Is your code open source?

    Safeheron core algorithms, signing machine, etc. will be gradually open source, view Safeheron open source on GithHub

  • What should I do if the creator's local private key shard is lost?

    If the creator's local private key shard is lost, you can recover it using the backed-up recovery phrase.

  • What should I do if the backup user's private key shard is lost?

    If the backup user's private key shard is lost, you can use the Safeheron App and back it up again.


  • Support speeding up or canceling transactions?


  • Support EIP-1559?


  • Does Safeheron support dApps?

    Safeheron provides a Web3 browser extension and REST API as well as flexible approval flows to enable a secure interaction with dApps. Safeheron also gives you the ability to have multiple users manage assets at the same time.

  • Why are transaction fees lower with Safeheron?

    The MPC MultiSig algorithm computes signatures using pure mathematical algorithms. As the Secure MPC runs off-chain, it appears just like a standard single signature transaction when it's on the chain, thus incurring a similarly low transaction fee. This is in contrast to the significantly higher fees incurred by BTC native MultiSig or EVM smart contracts during the multi-signature process.
