Hot Wallet
Definition
A hot wallet is a cryptocurrency wallet connected to the internet, enabling convenient transactions but with increased attack surface. Mobile apps, desktop wallets, and exchange wallets are typically hot wallets. Quantum-resistant hot wallets provide post-quantum security with online convenience.
Technical Explanation
Hot wallets store private keys on internet-connected devices. This enables instant transactions without air-gap transfers. Security relies on device security (OS protections, encryption, authentication) plus cryptographic security of the algorithms used.
Quantum threat considerations: hot wallet keys face both classical hacking risks and future quantum key-derivation attacks. Using quantum-resistant algorithms (Kyber-768, SPHINCS+) eliminates the quantum threat vector while standard security practices address classical risks.
SynX Relevance
SynX provides quantum-resistant hot wallet functionality for convenient daily use. Your Kyber-768 and SPHINCS+ keys are encrypted at rest and protected during operations. For larger holdings, combine hot wallet convenience for spending amounts with cold storage for savings.
Frequently Asked Questions
- Are hot wallets safe?
- Reasonably safe for appropriate amounts with good security practices. Use cold storage for large holdings.
- How much should I keep in a hot wallet?
- Only what you need for near-term transactions—like cash in your physical wallet.
- Does quantum resistance make hot wallets safer?
- Against future quantum attacks, yes. Standard security practices still matter for classical threats.
