Protect your crypto before quantum breaks it.
QSHIELD scans Solana wallets, tokens and programs for quantum exposure, then moves what matters into vaults that only open with hash-based signatures.
Your address is already public.
A Solana address is an ed25519 public key. It's on chain the first time anyone sends you something. Classical computers can't work backwards from it to your private key.
A large enough quantum computer running Shor's algorithm could. Because the chain keeps everything, those keys can be collected today and attacked later. Moving after that day is too late for any key that was already exposed.
QSHIELD is built for everything that already exists: wallets, treasuries, tokens and protocols.
Five layers, one network.
Start with a free score. Move assets into post-quantum vaults when you're ready. Let Sentinel and pre-set rules handle the moment it matters.
How exposed is your wallet?
Paste any Solana address. We check the key type, what the address holds and how long it has been active, then score how much a quantum attacker could reach. Free, and nothing is stored.
Vaults that don't trust curves.
SOL in a QSHIELD vault sits at a program address with no elliptic-curve key behind it. It only moves with a one-time Winternitz signature, built from hash chains in your browser.
Shor breaks curves. Not hashes.
Shor's algorithm breaks the discrete-log problem behind ed25519. Hash functions don't have that structure. The best known quantum attack on them, Grover's search, only square-roots the work, so a 256-bit hash still leaves around 2¹²⁸ steps.
Every withdrawal rotates the key.
A Winternitz key is 67 secret values. Signing reveals a point partway along each value's hash chain. Anyone can finish the chains and check they land on your public key. Reusing a key leaks more of each chain, so every vault withdrawal rotates to a fresh one.
This panel runs a real Winternitz one-time signature with SHA-256 in this page. Nothing leaves your browser.
Sentinel watches the labs so you don't have to.
AI agents read research papers, hardware roadmaps and standards updates, separate real milestones from press releases, and move the network's threat level when the evidence does.
Watch
Level changes need two independent agents and a human reviewer to agree before any trigger can fire.
Decide now what happens on q-day.
Pre-authorize a narrow, capped transfer into your own QSHIELD vault. It can only go to you, only up to your limit, and only when a verified trigger fires.
Signing records your rule. It's free and doesn't move funds.
Launch shielded.
Every coin launched on QSHIELD is born quantum-ready: authorities locked down, treasury in a post-quantum vault, and a public readiness score holders can check before they buy.
Readiness score updates as you choose. Holders see it on the coin page.
Prove your protocol is ready.
Projects pay QSHIELD to audit their quantum readiness. Every report is hashed and signed on chain, so holders can check it hasn't been edited after the fact.

- Sentinel alerts for your team
The $QSHIELD flywheel.
Vault and audit fees are real protocol revenue. Revenue buys $QSHIELD on the market, burns part of it, and funds the next round of security tools.
Shielded launches
Shielded launches make new tokens quantum-ready from day one, with locked authorities and treasuries in post-quantum vaults.
The bigger job
The bigger job is what already exists. Most value on Solana sits in wallets, treasuries and protocols created long before anyone thought about q-day, and all of it may need to move.
Quantum security for a brighter tomorrow.
