Security FAQ

Common questions about QFS security

How are my private keys stored?

Your private keys are encrypted with quantum-resistant algorithms and split into multiple shards using Shamir's Secret Sharing. No single person or system has access to complete keys.

What happens if QFS goes bankrupt?

Your assets are held in non-custodial wallets. You always have full control and can withdraw at any time. QFS never has access to your private keys.

Is my account insured?

Yes! All accounts are covered by our $500M insurance policy through Lloyd's of London. This covers both hot and cold wallet assets.

How often are you audited?

We undergo third-party security audits quarterly. All audit reports are published and available for download.

Can I self-custody my keys?

Yes! QFS supports hardware wallets (Ledger, Trezor) and you can always export your private keys.

What's your bug bounty?

We offer up to $1,000,000 for critical vulnerabilities discovered by ethical hackers.
