Walk through scanning a wallet for post-quantum exposure in 3 clicks.
A PQC scan tells you whether a given wallet's cryptographic footprint is exposed to a future quantum attacker. Here's how to run one.
Step 1 — Open the Scanner
Click /scan in the top nav. You'll see a chain picker and an address input.
Step 2 — Pick a chain
We support 18 chains today across four families:
- Bitcoin family — Bitcoin, Litecoin, Bitcoin Cash, Dogecoin
- EVM — Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base
- Solana, Tron, Aptos, Sui
- Cosmos — Osmosis, Celestia, Sei, Injective
If you don't see your chain, tell us here — we ship new ones every fortnight.
Step 3 — Paste an address and hit Scan
You'll see a results card within ~5 seconds:
- Quantum Score — 0-100, lower is worse exposure
- Tier — Critical / High / Moderate / Low
- Balance at risk (USD) — only the value sitting on exposed pubkeys
- Factors — the specific things that drove the score (re-used pubkey, ECDSA signature, no rotation, etc.)
What "exposed" really means
For Bitcoin-family chains: your public key only becomes visible the first time you spend — once exposed, that address is forever vulnerable to a future Shor attack. Best practice: rotate to a fresh address after every spend.
For EVM/Solana: pubkeys are derived deterministically from accounts and are visible from block 1, so the question is when PQC migration becomes mandatory (NSA says 2030/2035 for federal systems).
