Post-quantum by default

Most wallets aren't ready for quantum computers. Qbit Wallet is.

Most wallets today

Signatures
Elliptic-curve signatures, such as ECDSA or Schnorr.
Keys on-chain
Your public key is revealed once you spend, and some address types show it from the start.
Quantum risk
A large enough quantum computer running Shor's algorithm could work out the private key.

Qbit Wallet

Signatures
SLH-DSA, a hash-based post-quantum signature, on every spend.
Keys on-chain
P2MR outputs commit to a Merkle root, so no public key sits exposed while your QBT is at rest.
Quantum risk
Security rests on hash functions, which Shor's algorithm cannot break.

Security and privacy

Your keys stay with you

  • Encrypted on your device

    Keys are created in the extension and encrypted with your password.

  • Locks when you step away

    It locks after 3 minutes of inactivity by default, and you can set your own timer.

  • You approve every site

    Sites see your address only after you connect them, and you can revoke access any time.

  • Phishing protection

    Known phishing sites are blocked, and sites the wallet can't verify get a warning.

Which browsers does it work in?
Chrome 114 or later. Other Chromium browsers that install from the Chrome Web Store, such as Brave and Microsoft Edge, can use the same listing.
Which networks does it support?
Qbit Mainnet and Testnet4. Switch between them from the network menu in the wallet.
How do I get QBT?
Copy a receive address and mine to it with Qbit Pool, or find exchanges and other services on the Ecosystem page.
Can I use a hardware wallet?
Not yet. Hardware wallets don't support Qbit's post-quantum signatures today.
