Document fraud, domain impersonation, and classical PKI expiry are three separate problems with one solution: cryptographic proof anchored to a permanent on-chain record.
A modified contract, a backdated agreement, a forged board resolution — without cryptographic signing at creation, neither party can prove what the original said or when it was authorised. The dispute always favours the forger.
Business email compromise and domain impersonation cost $2.9B in 2023 (FBI IC3). A KXCO domain attestation gives counterparties a cryptographic check — one that cannot be faked, cannot be spoofed, and updates in real time.
PDF digital signatures and classical PKI will be breakable by quantum computers. Documents signed today under RSA or ECDSA will be repudiable in the 2030s. The verification horizon matters — especially for wills, IP filings, and long-term contracts.
KXCO's scanner fingerprints your domain and submits an attestation to the KXCOVerifiedRegistry smart contract on Armature L1. A tamper-evident badge is served at verify.kxco.ai — one click confirms your domain is KXCO-verified. Updates automatically when your domain configuration changes.
Upload your document. KXCO applies an ML-DSA-65 signature and anchors the document hash to Armature L1. The signed document is yours — verifiable offline via kxco-verify (JS/Python/Rust/Go) with no KXCO server required. Every future check proves the document is unchanged from this exact moment.
An SVG badge embeds in your site, document metadata, or email footer. One click takes any counterparty to the on-chain attestation record. No login, no account, no trust in KXCO required — the proof is on a public blockchain.
The on-chain attestation in KXCOVerifiedRegistry is immutable. No one — not KXCO, not the signer, not a court order — can alter the record of what was attested and when. The block number is the timestamp. The chain is the authority.
Cryptographic attestation that your domain is controlled by the verified entity. Independently verifiable at verify.kxco.ai. Badge embeds anywhere. Updates automatically. Counterparties verify in one click.
$99/yrML-DSA-65 post-quantum signing of any document — contracts, board resolutions, IP filings, compliance statements. Every signed document anchored to Armature L1. Verifiable offline, no KXCO server required, 30-year horizon.
$29/doc or $199/moEnterprise identity and signing platform for staff, counterparty credentials, and institutional onboarding. White-label under your brand. ML-DSA-65. HSM-backed. PKCS#11 integration. Deployable within your regulatory perimeter.
EnterpriseSign every article, press release, or official communication. Authors and publications carry a verifiable identity badge. Recipients know this communication originated from your domain and has not been altered since publication.
$29/articleEvery tier is production-grade. The entry product is priced to remove any barrier to starting. The value compounds as you add surfaces.
All plans require a minimum annual commitment. Volume pricing available. Academic and government pricing available on request.
A KXCO-signed document is verifiable by any counterparty, in any jurisdiction, now or in 30 years. The proof lives on-chain — not in your email thread, not in a database that can be breached, not in a PDF whose signature expires.
Domain Trust takes minutes to deploy. Document Trust ships in the same session. Start with the entry product — $99/yr — and build the trust chain from there.
