“Corda’s unique scalability and security attributes make it ideally suited to heavily regulated environments and we wanted a custodian that operated with those same features. We have found that in Hex Trust and its commitment to the end-to-end safekeeping of digital assets.”

— Cathy Minter, Chief Revenue Officer at R3

Safekeep Assets

Hex Safe has been designed with a multi-layered architecture to deliver the highest degree of security for the assets held in custody.

  • Secure Backup – upon request, all application data, including encrypted assets and in-flight transactions, are replicated in real-time to the backup datacenter.
  • Account Structure – Hex Safe offers extreme flexibility to create hierarchical structures of accounts and sub-accounts. All accounts and sub-accounts are completely segregated on chain and derived through different seeds to offer the highest degree of safety and third-party auditability.
  • Customizable User Roles – built with an institutional mindset to mesh with financial institutions processes and workflows. The platform allows six user roles to enable complete Segregation of Duties (SoD) and eliminate Single Points of Failure (SPoF) by distributing critical functions and responsibilities governing transactions processes across several functions/departments.
  • Wallet Policies – to further enhance security, policies can be created by an Administrator to limit the ability to transfer assets into or out of a custody wallet.
