Problem
Storing significant amounts of Bitcoin in a single location creates a substantial target for both digital and physical theft. This concentration of assets makes individuals vulnerable to sophisticated attacks, including violent coercion, leaving their holdings at risk.
Solution
Frostsnap offers a distributed hardware security system designed for enhanced Bitcoin self-custody. The core architecture utilizes a 2-of-3 multisignature scheme, requiring any two distributed devices to authorize a transaction. This approach provides inherent disaster redundancy and robust coercion resistance by eliminating single points of failure. Unlike traditional hardware wallets that rely on a single trusted device for key management, Frostsnap integrates a user's phone or laptop into the secure key generation and verification process, mitigating risks associated with compromised hardware.
Target Audience
The primary target audience includes Bitcoin holders seeking advanced self-custody solutions, particularly those with substantial holdings who require robust protection against physical and digital threats, and individuals prioritizing disaster recovery and coercion resistance.
