- Problem Statement: The need for a secure, low-cost hardware storage solution for the dotsama ecosystem.
- Significance: Current solutions are expensive (€500+), complex, and have a larger attack surface due to reliance on mobile OS and extra platform features.
- Proposed Solution: Develop Kampela, a card-shaped device that functions as a hardware version of Parity Signer. It will accept data through a unidirectional NFC port, display output on an e-paper screen, and perform all signing operations on-chip. The device will be priced below €100 and will only support a single seed phrase per unit.
- Expected Outcomes: A secure, affordable, and user-friendly hardware storage solution for the dotsama ecosystem. The device will have all the security features of Parity Signer and will be able to replace Signer when providing signatures back to a mobile/desktop wallet. The proposal does not include actual production but will result in all preliminary development required for production.
