Use Cases

  • The Workspace can be used for asset statistics for a specific business line, while wallets are assigned to different users.
  • The Workspace can be used for overall company asset statistics, with wallets assigned to different business departments.
The Private Key Password is used for encrypting and decrypting private key shares and is crucial for your asset security. Please ensure timely backup. The backup methods and password are essential for the secure use of the MPC System.
  • ChainUp Custody uses a 3-3 signature strategy, with two private key shares encrypted and stored on Microsoft and Amazon cloud services, and one private key share stored locally on the user’s device.
  • Users have 100% control over their assets: ChainUp Custody only assists users in managing assets and cannot access user assets without the user’s private key share signature. Therefore, users need to promptly back up and securely store the local private key share.
  • For user convenience, the private key share exists in the form of a recovery phrases.
If the workspace configuration does not meet your requirements, please contact your dedicated Business Manager or email to custody@chainup.com for support.
