The Bitcoin protocol is quantum-resistant. Your wallet is not. PQ Shield wraps existing wallets with post-quantum authorization—without replacing them.
Most commentary gets this wrong. Here's what quantum computers will—and won't—break.
A post-quantum protection layer that wraps your existing wallet—without replacing it.
Dual signature: ECDSA (required by chain) + Dilithium/SPHINCS+ (stored as receipt). Quantum-resistant proof of intent survives even if ECDSA is broken.
Time-locked execution with delayed reveal. Even if your transaction is captured today, PQ re-authorization is required at execution.
Offline PQ recovery key with policy-locked rotation. Even if your wallet is compromised, your assets are recoverable.
Policy-gated transactions: transfers over $X require PQ + delay. MetaMask becomes a policy wallet, not just a keypair.
Wallet exposure metrics, address reuse risk, and migration readiness assessment. Know exactly where you stand.
MetaMask, Coinbase, Ledger, Phantom—PQ Shield wraps the wallet you already use. No migration required.
This distinction matters for credibility and legal safety. We solve the real problem without overclaiming.

Harvest-now, decrypt-later is not theoretical. Nation-state actors are already collecting encrypted traffic, waiting for quantum capability.
Your wallet's public key—visible on-chain every time you transact—is being recorded. When quantum computers arrive, those keys can be reversed to derive your private key.
The question isn't whether to migrate to post-quantum protection. It's whether you do it before or after your keys are compromised.
PQ Shield uses the same cryptographic receipt infrastructure that powers FairStamp timestamps. Every PQ authorization is receipted, auditable, and verifiable—the same dual-source verification you trust for content provenance, now protecting your wallet.
