  • Passphrase <-> Private Key conversion logic, plus
  • Local storage of your crypto keys.
  • Security: Driven by the Mean Threshold Multi-sig, BLS, Smart Contract Accounts/Wallets, and MFA, hacking a Super Safe wallet becomes exponentially hard as the attacker will need to perform social engineering and technology penetrations on more than one person across multiple devices to execute a malicious transaction.
  • Usability: The easiest way to think about the usability of a Super Safe is like a Business Bank account (think Brex, or whatever you consider the best banking experience you’ve ever had for a business). In this “business” setting, a set of owners/authorized personnel can configure a set of rules and policies for the Super Safe, such as expenses, limits, account locking, etc. for each of the people in the organization, therefore limiting beforehand the worst-case scenario in the case anyone gets compromised.
  • Privacy: Across the different technologies leveraged for the Super Safe, privacy is at the core of its decisions. The Mean Multi-sig is 100% DeFi without any centralized infrastructure. The MFA security around it has minimal centralized infrastructure blueprint to support multi-sig MFA for the Super Safe, mainly through on-device biometric verification (FaceID, TouchID, etc.), or 3rd party authenticator apps (Google Auth, Authy, etc.), or traditional communication infrastructure (email and SMS). Super Safe keeps privacy as a core tenant with no KYC/B, no custody, and no login required.



People and businesses from around the world can create and manage international accounts with thousands of assets like stables coins and tokens, as well as access to several capital products like deep liquidity markets, a decentralized exchange, and access to several investments.
