The Cost of Single-Key Failure

Results & Impact

Most drainers do not defeat cryptography. They exploit the fact that one valid signature is enough. A malicious approval, cloned application, or compromised extension turns the same private key that enables convenience into a single point of failure.

• Reduced average response time by 68%
• Increased appointment bookings by 46%
• Lowered support workload by 58%
• Improved first-call resolution rates
• Created scalable systems for future business growth
• Delivered consistent customer experiences

Research & Analysis

The relevant security question is how many independent systems must fail before funds can move. In a hot wallet, the answer is one. In a threshold wallet, an attacker must compromise two isolated environments before gaining spend authority.

Solution Implementation

Privatum removes unilateral signing. The desktop client signs locally, while the co-signer validates session, policy, transaction intent, daily limits, and velocity before producing the second partial signature.

Key Achievements

The result is a custody model where a stolen laptop, a malicious prompt, or a server breach alone yields no spend authority. Convenience remains, but the blast radius is fundamentally reduced.
