Your address is a lock everyone can see
Your private key is the combination. Today's computers would need billions of years to work it out from the lock alone. That's why crypto works.
Solana · post-quantum readiness
Is your wallet ready for Q-Day?
Every ordinary Solana address is its public key, in plain view. A powerful enough quantum computer could one day work backwards from it to the secret key. Paste any address and see what sits behind it.
Read-only. No wallet connection, nothing to sign, so you can check any address.
How it works, simply
Crypto wallets are locks. Today's locks are excellent against today's computers. A different kind of machine changes the arithmetic.
Quantum computers are good at exactly that puzzle
None is strong enough yet, and nobody knows when one will be: maybe years, maybe never. The day it happens is called Q-Day.
A different kind of lock fixes it
Hash-based locks rely on maths quantum computers are bad at. Each combination works once, so funds move to a fresh lock every time they're spent.
Reading the result
"Exposed" describes readiness, not danger today. No quantum computer can do this yet, and Solana has a plan to move to post-quantum signatures when it's needed.
- Shielded
- An off-curve address (a program derived address). No private key exists, so there's nothing to recover.
- Exposed · empty
- The key is public, but there's nothing behind it.
- Exposed · low
- Under $1,000 behind a public key.
- Exposed · medium
- $1,000 to $100,000 behind a public key.
- Exposed · high
- Over $100,000 behind a public key.
The quantum vault
QAULT Vault keeps SOL behind one-time hash-based keys and moves your funds to a fresh key every time you spend. Try it now on devnet with test SOL. It goes live only after an independent audit.
Mainnet waitlist
Be first through the door
Leave an email or a Solana wallet address, and you'll be among the first let into the mainnet beta, once the vault has passed its audit.
No spam. One email when mainnet opens.
