Free tool
Is your crypto wallet safe from quantum computers?
BMIC's wallet vulnerability checker scans any Ethereum or Bitcoin address and returns an instant quantum-risk grade — based on the wallet's actual on-chain signature history. Free for everyone. No token required. No private keys ever leave your device.
Why this check matters now
Every cryptocurrency wallet that has signed a transaction has revealed its public key permanently on-chain. Once revealed, that public key is harvestable forever — recorded by every blockchain explorer, every node, every adversary. When a sufficiently large quantum computer is available, Shor's algorithm can derive the private key from the public key in polynomial time. This is the harvest-now-decrypt-later (HNDL) attack model, and it is the operative threat for crypto holders today — not in 2050.
NIST has ratified post-quantum-cryptography replacements (FIPS 203, 204, 205) precisely because the U.S. government has formally concluded ECDSA-based signatures will not survive Q-Day. BMIC is the only active crypto presale built on those NIST-ratified standards. The wallet checker tells you, today, whether your existing wallets are exposed.
What the checker analyses
- Public-key exposure — has this address ever signed a transaction? If yes, public key is permanently revealed. The tool flags every signed-from address as elevated risk.
- Address reuse — multiple transactions from one address compound exposure (the public key is revealed once and then funds keep accumulating behind it).
- Balance-at-risk — current dollar-equivalent of funds sitting on quantum-vulnerable signatures. This is the number you actually care about.
- Migration recommendation — specific actions to reduce exposure: rotate addresses, consolidate to fresh addresses, move to a PQC-secured wallet, deploy ERC-4337 account abstraction.
- Historical timeline (token holders) — when each public key was first exposed, ongoing risk graph, alerts on new exposures.
How to use it
- Click Run the wallet checker above (no signup needed for the basic check)
- Paste any public address — Ethereum, Bitcoin, or any EVM-compatible chain
- The tool reads on-chain data only. No private keys, no signing, no wallet connection
- Get your risk grade and balance-at-risk in under 10 seconds
- Optional: register the address with your BMIC token-holder account for ongoing monitoring
Why we built this
BMIC's mission is post-quantum cryptocurrency. Telling people their existing wallets are at risk is the first step. The wallet checker is free and public because the quantum-cryptography conversation needs to be evidence-driven, not theoretical. Once you see your real balance-at-risk number, the case for migrating to PQC-secured custody stops being abstract.
BMIC token holders get the deeper version of the tool: full historical analysis, monitored alerts, recommendations, and a direct migration path into the BMIC quantum-secure wallet. See /tokenomics/ and / for the presale.
Frequently asked
Is the wallet checker actually free?
Yes — basic vulnerability checks are free for everyone, no token required. Token holders get extended history and ongoing monitoring.
Does the tool need my private key?
No. It reads only public on-chain data. Private keys never leave your device. There is no wallet-connect step. Paste a public address; that's it.
Which chains does it support?
Ethereum and EVM-compatible chains (Polygon, Arbitrum, Optimism, BNB Chain, Base), plus Bitcoin. More chains added periodically.
If my wallet is high-risk, what should I do?
Move funds to a fresh address that has not yet signed a transaction (its public key is still hidden behind a hash), then migrate to a post-quantum-secure wallet before signing again. The BMIC quantum-secure wallet ships with this migration flow built in.
