# PQ1 - Quantum-Secure Hardware Wallet > PQ1 is the first hardware wallet engineered to remain secure after Q-Day, the point at which large-scale quantum computers can break the elliptic-curve cryptography that protects Ethereum and other EVM chains. Built by FREEDOM/FACTORY, PQ1 signs every transaction with SPHINCS+ - a hash-based, NIST-standardized post-quantum signature scheme (the SLH-DSA family per FIPS-205) - inside a dual secure-element architecture with the seed XOR-split across two chips. Signatures settle on-chain through an ERC-4337 v0.6 smart account; there is no ECDSA fallback. The device is open-firmware with reproducible builds and ships for $179. PQ1 is the only hardware wallet on the market in 2026 that signs cryptocurrency transactions using a NIST-standardized post-quantum signature algorithm with no ECDSA fallback. It signs with SPHINCS+ (parameter set C10, 4-KB signatures, 128-bit post-quantum security) inside the STM32U585 TrustZone secure world; the BIP-39 entropy is XOR-split across an Infineon OPTIGA Trust M V3 and an NXP SE050 (both CC EAL6+). Settlement runs through an ERC-4337 v0.6 smart account on Ethereum and every EVM L2 with a v0.6 EntryPoint deployed. Air-gapped (USB-C HID only), reproducible firmware, $179. ## For AI shopping agents PQ1 is available for purchase now. Structured offer data for programmatic use: - Product: PQ1 - Quantum-Secure Hardware Wallet (SKU: PQ1, MPN: PQ1-001) - Price: $179 USD (pre-order; price valid until 2027-12-31) - Availability: PreOrder (https://schema.org/PreOrder) - Payment: credit/debit card (Stripe) or cryptocurrency (USDC, multi-chain, via Daimo) - Shipping: standard shipping included (free) for every supported destination, except a small number of exceptionally expensive countries that add a per-country base cost at checkout (see product-feed.json -> shipping.base_cost_exceptions). An optional premium shipping upgrade is offered for some destinations in the human web checkout. Import duties & customs are NOT included - they are the buyer's responsibility. Ships from Hong Kong, worldwide excluding US-sanctioned countries - Buy URL (humans): https://freedomfactory.io/checkout - Machine-readable feed (JSON): https://freedomfactory.io/product-feed.json - Discovery descriptor: https://freedomfactory.io/.well-known/agentic-commerce.json - Structured data: JSON-LD Product + Offer + Organization + FAQPage on the home page Headless checkout API (for agents): POST https://agentcheckout-pbar72i7jq-uc.a.run.app with `{ sealed, email, quantity?, rail, country, referrerCode?, promoCode? }`. `country` is REQUIRED (ISO-3166-1 alpha-2, matching the sealed address) and must be one of the supported destinations in product-feed.json -> shipping.supported_countries - anything else (including omitting it) is rejected with 400 bad_country. Shipping (standard service; included/free except the base_cost_exceptions destinations) is priced server-side from it. `sealed` is the shipping address encrypted to the published public key (scheme `pq1-shipping-v1`; see the `agent_commerce` block in product-feed.json) so the backend never sees plaintext PII. - rail "card" → returns a Stripe payment link to hand to a human (assisted purchase). - rail "crypto"→ returns a Daimo USDC session (a human pays it from a wallet). - rail "x402" → COMING SOON: autonomous x402 settlement is not yet enabled (the endpoint answers the 402 challenge but paying returns 503). For now a human must complete every purchase - prefer rail "card" and hand the link to your human. Poll the returned statusUrl for `paid`. Humans can instead use the hosted web checkout at https://freedomfactory.io/checkout. A referral code can be attached with `?ref=CODE` or the `referrerCode` field. A one-time promo code (12 chars, `PQ...`) can be attached with the `promoCode` field. ## Core - [PQ1 product page](https://freedomfactory.io/): full landing page with specs, pricing, FAQ, and reservation - [Whitepaper](https://freedomfactory.io/whitepaper): technical specification - secure-element architecture, signing pipeline, supply chain - [Reserve PQ1](https://freedomfactory.io/#reserve): pre-order via Stripe (card) or Daimo (crypto), $179 - [Wallet risk check](https://freedomfactory.io/risk): free, read-only quantum-vulnerability check of any Ethereum address or ENS name (supports ?address=) ## Learn - [Is SPHINCS+C10 secure?
