smshPQTM signs every inference call with a NIST-finalized lattice signature in under a millisecond. Today's classical signatures become forgeable the day a cryptographically-relevant quantum computer arrives. Every audit log, every routing decision, every cache hit you sign today with Ed25519 or ECDSA is harvested now and decrypted later. smshPQ closes that window — and pays for itself on the cost side while it does.
NIST finalized ML-DSA in FIPS 204 in August 2024. The NSA put it on the CNSA 2.0 list with a 2035 hard deadline for national-security systems. The harvest-now-decrypt-later attack does not need a quantum computer to start — adversaries are storing your signed traffic right now. Inference receipts are the longest-lived secrets you produce.
Enter your monthly call volume and current cost. We'll show the cache-proof savings, the verified-routing savings, and the net cost after the smshPQ™ receipt fee. No accounts. No gimmicks. The math is the math.
A signed hash is small, fast, and proves three things at once: which model ran, what scope it was allowed, and whether the answer was already paid for. Each unlocks a different line of cost.
If a prompt+context hash matches a prior signed response from the same model, serve it from cache with cryptographic proof of equivalence. The buyer trusts the hit. The vendor saves the inference.
Today, buyers overspend on premium models because they cannot verify which model actually answered. smshPQ™ signs the model ID into every receipt. Route freely between Claude Haiku, GPT-4.1-mini, Gemini Flash — and prove it on the way out.
Most regulated buyers run inference at 30-40% of capacity because they cannot audit at scale. smshPQ™ gives the regulator the receipt, the counterparty the proof, and the holder the keys — without revealing the prompt or the output.
smshPQ™ sits inline with the inference call. Zero model change. Zero protocol break. The receipt is a 384-byte ML-DSA-65 signature over a canonical hash of (prompt, model, scope, output) — anchored on Base in batched commits.
Send a single line of API traffic. We'll instrument smshPQ™ inline, show your real cache-proof rate and verified-routing rate against your actual prompts, and walk you through the deployment in a 20-minute call.
