Sepior Advanced MPC TSM™

MPC For BYO Wallet

Sepior Advanced MPC TSM™ provides the industry’s most advanced multiparty computation (MPC)-based key protection and threshold signing system available, designed for easy integration into your own in-house developed wallets for institutional-grade custody services

 

World-class key security for any wallet

  • Self-hosted for direct control of all MPC key shares/nodes

  • Protects against internal and external threats

  • Any wallet type: Hot/Warm/Cold

 

Advanced MPC for industry-leading…

  • Security: purpose-built MPC protocols for digital asset security

  • Performance: milliseconds signing latency, up to 10,000 tps or more

  • Flexibility: any protocol, wallet type, custody type, deployment model

 

Secure m of n MPC quorum approval

  • Key shares are used by each party to approve a transaction

  • No complete key exists on any device, eliminating single points of failure

  • When m of n quorum approval is satisfied, Partial Signatures are used to create a Threshold Signature (ECDSA, EdDSA...)

  • Multiparty approval, elimination of an entire key, and the output of a single signature enhance security and operations

 

Sustainable secure operations

  • MPC provides secure operations even with some parties become corrupt or unavailable
