Post-quantum · On-chain · Independently verifiable

Your domain,
cryptographically proven.

KXCO Verified seals your domain with a post-quantum cryptographic signature and anchors it permanently on KXCO Chain. One badge. Anyone can verify it — without trusting KXCO.

Why it matters

Three things your badge proves — that no screenshot or certificate authority can.

🔐

Instant trust signal

Visitors see a badge that links directly to an on-chain record. No middleman, no expiry delay, no PDF to download.

⛓

Tamper-evident forever

The attestation is written to KXCO Chain. It cannot be altered, back-dated, or removed — even by KXCO.

🛡

Post-quantum ready

Signed with ML-DSA-65 — NIST FIPS 204, the algorithm the US government now mandates for federal systems.

🔍

Independently verifiable

Anyone can verify your attestation directly via RPC using open-source tools. KXCO's servers are not in the verification path.

How it works

Three steps. Live in 24 hours.

Choose a plan, submit your domain. KXCO confirms and activates your subscription.

We attest

KXCO's scanner evaluates your domain, signs the result with ML-DSA-65, and writes the attestation to KXCO Chain.

Embed & go

Add one line of HTML to your site. The badge queries the chain in real time and turns grey the moment it's revoked.

What “Verified” means — and what it doesn’t

We say what we can prove. Nothing more.

✓

Cryptographic proof of integrity. The artifact matches the signed record. If configuration has changed since attestation, the signature fails.

✓

Tamper-evident, permanent record. Anchored on a public blockchain. Verifiable without asking KXCO for anything.

✓

Post-quantum signature. ML-DSA-65 (NIST FIPS 204). Endorsed by UK NCSC. Resistant to quantum computing attacks.

✗

KXCO Verified does not attest to the content of documents, legal validity, or regulatory status of any verified party.

Pricing

No free tier. No feature-locked trials. Clear pricing, clear proof.

Questions

Can someone fake the badge?

No. The badge is served live from KXCO Chain — it queries the actual on-chain record every time it loads. A copied badge image would be static and obviously fake. The real badge turns grey the moment an attestation is revoked or a subscription lapses.

What if I let my subscription expire?

The badge enters a 30-day grace period (grey, unverified). After 30 days it displays the red Expired badge. The on-chain record remains permanently — only the active-subscription gate changes. Renewal restores the verified badge instantly.

How do I verify independently — without going through KXCO?

Use any JSON-RPC client pointed at https://chain.kxco.ai/rpc and call latest(keccak256(domain)) on the registry contract. No KXCO API involved. See the developer docs for a ready-to-run example.

What is ML-DSA-65 and why does it matter?

ML-DSA-65 is NIST FIPS 204 — the US government's new post-quantum digital signature standard, also endorsed by the UK NCSC. It is resistant to attacks by quantum computers. ECDSA (used by most TLS certificates today) is not. KXCO Verified signs every attestation with ML-DSA-65.

How long does it take to go live?

Typically within 24 hours of confirmed payment. You'll receive the one-line embed code by email. The badge is live the moment the attestation transaction confirms on-chain.
