Can I Use a Quantum-Resistant Wallet on Mobile?

Quantum-resistant wallets are available for mobile platforms (iOS and Android), providing post-quantum security with the convenience of smartphone access. Modern mobile devices have sufficient computational resources to execute Kyber-768 and SPHINCS+ operations efficiently.

Mobile quantum-resistant wallets handle key generation, transaction signing, and network communication using the same NIST-standardized algorithms as desktop versions. The cryptographic libraries are compiled for ARM architectures common in smartphones, with optimization for mobile processors.

Performance on mobile devices is adequate for typical wallet operations. Key generation completes in seconds, transaction signing finishes within perceivable but acceptable timeframes (sub-second for most transactions), and network operations proceed as quickly as connectivity allows.

Security considerations for mobile quantum-resistant wallets include device encryption (enable full-device encryption), biometric authentication (fingerprint or face recognition for wallet access), secure element utilization where available, and malware protection through app source verification.

Battery impact is minimal. Post-quantum operations require more computation than ECDSA but execute infrequently (only during key generation and transaction signing). Normal wallet usage—checking balances, viewing transaction history—has negligible battery effect.

Storage requirements are moderately higher due to larger key sizes and signature caching. Modern smartphones with gigabytes of storage accommodate this easily. Ensure adequate free space during installation.

Backup procedures are essential. Mobile devices are more prone to loss, theft, or damage. Secure your recovery phrase offline before storing significant funds. Mobile wallets should complement, not replace, more secure storage methods for large holdings.
