Multi-party computation (MPC)

Private keys are never created or held as a single whole. Key material is split into independent shares in separated environments, and signatures are produced collaboratively — no single party ever reconstructs a complete key. This removes the single-key point of failure of traditional wallets and the fragility of on-chain multisig. MPC is the default; multi-signature and other models are available on request.

Why MPC

How it compares

Legacy wallets

Single key or on-chain multisig

  • A single private key is a single point of compromise
  • On-chain multisig adds cost and an on-chain footprint
  • Setups are often chain-specific and operationally rigid
  • Key handling exposes material to hosts or operators
MPC at Equentor

Distributed shares, off-chain

  • Keys are split into shares and never reconstructed
  • Signing is coordinated off-chain, with no extra on-chain footprint
  • One consistent control model across networks
  • Shares operate inside hardware-isolated enclaves

Hardware isolation

Key-share and signing operations run inside hardware-isolated secure enclaves — never exposed to the host OS or operators.

Policy & governance engine

Every transaction passes programmable rules: m-of-n approvals, per-asset and per-destination limits, and time windows.

Allow-listing & anti-spoofing

Destinations can be allow-listed, with protection against address-spoofing and malicious-change attacks.

Cold & warm tiers

Assets distributed across cold and warm storage, with policy enforced at each tier.

Monitoring & audit

24/7 monitoring with complete, tamper-evident audit logging of operations.

Disaster recovery

Secure key-share backup and tested recovery procedures support business continuity.

Network coverage
