Custodial Multi-Party Computation
Custodial Multi-Party Computation involves a service provider using advanced cryptographic techniques to manage client assets without ever holding a single, full private key. Instead, the provider and the client hold different shards of the key, which are used to sign transactions collaboratively.
This model eliminates the risk of a single point of failure inherent in traditional custodial services. It allows institutions to offer high-security custody solutions while maintaining regulatory compliance and auditability.
Because the key is never fully reconstructed, the risk of key theft from the custodian's servers is drastically reduced. This approach is becoming the industry standard for institutional crypto asset management due to its superior security profile.
It enables a hybrid model where the client retains partial control while benefiting from the infrastructure of a professional custodian.
