Cobo uses advanced MPC cryptography with a Threshold Signature Scheme (TSS), generating key shares independently across multiple devices and locations. A full private key never exists at any time, eliminating single points of failure and protecting your assets from both external attacks and insider threats. Even the most sophisticated attackers can't compromise the system by targeting a single point.

Cobo leverages Trusted Execution Environments (TEEs), including secure enclaves like Intel SGX, to encrypt key shares at the hardware level. Even if the server's operating system is compromised, the hardware-based isolation ensures that private key shares remain secure and inaccessible.

We use a hot-warm-cold private key storage system, with 95% of assets securely held in ironclad cold wallets. This multi-layer approach guarantees top-level security while ensuring seamless liquidity through hot and warm wallets.

The Cobo Policy Engine acts as the final gatekeeper before any transaction is signed. Spending limits, address whitelists, multi-party approvals, and velocity controls — every rule you define is enforced at the infrastructure level, not in the application layer.

Every system, every transaction, every node is monitored around the clock. Real-time alerting, automated incident triggers, and a standing incident response team mean threats are addressed before they can materialize.
