For people, businesses, institutions & AI

Post-quantum infrastructure for verifiable objects & connections.

KXCO turns the things you work with — identities, AI agents, documents, payments — into verifiable objects, and lets you show how they connect. Everything stays post-quantum secure, and anyone can check it for themselves.

See what you get → Start building →

Built on post-quantum cryptography. Every action is signed and recorded so anyone can check it — no need to take our word for it.

The Problem

The locks protecting today's money and data are about to break.

Almost every bank, app and government system is protected by maths that a powerful new kind of computer will be able to crack. The computer isn't here yet — but data stolen today can be unlocked the day it arrives.

The deadlines to fix this are already set. KXCO is built so the things you own, sign and send stay safe — and stay provable — on the other side of that line.

Happening now
Encrypted data is being stolen today, to unlock later.
Deadlines are set
Governments have published when the switch must happen.
No room to wait
Switching over takes time. Starting now is the safe move.
Why Now

Three big shifts are happening at the same time.

01
The old security is expiring
The maths that protects money, logins and records is reaching its end. New "quantum-safe" standards are now the requirement, not a choice.
02
Money is moving online for good
Value is moving onto digital rails — stablecoins, tokens, instant settlement. Those rails only work if everyone can prove what's real.
03
AI is starting to act on its own
Software agents now spend, sign and decide without a human in the loop. They need a real identity and to be held accountable for what they do.

You can't solve these one at a time. KXCO is built for all three.

The deadlines are real
2024
New standards set
NIST publishes the quantum-safe standards (FIPS 203, 204, 205). The switch becomes a defined obligation.
Jan 2026
G7 roadmap
The G7 publishes a roadmap (nonbinding) naming the financial sector as a top priority for the switch.
2030
Old crypto deprecated
Under US guidance, today's RSA / ECDSA are deprecated; CNSA 2.0 makes quantum-safe signing mandatory.
2033
Quantum risk window
CNSA 2.0 reaches exclusive use. A capable quantum computer is widely expected within this window.
2035
US federal deadline
US federal systems must finish the migration. Quantum-vulnerable algorithms are disallowed.
KXCO meets the new standards in production today — built on NIST FIPS 203 / 204 / 205, so you start on solid ground instead of racing the clock.
Built for everyone in the digital economy

Whoever you are, you get a plain promise.

Humans, organisations and machines all need the same thing: to act, get paid, and prove who they are — without being faked or frozen out. Here's what that means for you.

People
Own your money and ID. Nobody can fake it, freeze it, or take it.

Objects & Relationships

Everything you work with is a verifiable object.

An identity, an AI agent, a signed document, a payment — each is a thing you can verify on its own. KXCO also lets you connect them, so you can show how they relate: who owns what, who authorised whom, what led to what.

Objects
Treat each identity, agent, document or payment as an object you can point to, verify, and trust on its own.
Relationships
Connect those objects to show how they relate — an agent that belongs to a company, a payment tied to a signed contract, an action taken by a verified person.
Always provable
Every object and every connection is signed and recorded, so anyone can check it — no need to take our word for it.
The Trust Stack

One foundation. Everything provable.

Five layers, all live, all built on the same verifiable foundation. Pick the one you need — or use them together.

01Prove who you areIdentity
Identity
KXCO Verified
Identity & agent identity
Live
A permanent ID for people, businesses and AI that anyone can check.
  • Your identity lives on the open record — not in a database that can be hacked or switched off
  • Counterparties verify you directly — no KXCO in the middle
  • AI agents get the same kind of identity — so an agent can be authorised, and held accountable, for what it does
Get verified →
02Sign things that hold upLegal execution
Legal execution
KXCO Sign
Post-quantum signing
Live
Sign agreements that stay provable and valid for decades — not just today.
  • Every signature is quantum-safe — it holds up against tomorrow's computers, not just today's
  • Anyone can confirm a signed document is genuine and unchanged, without going through KXCO
  • Built for contracts, board resolutions and filings where the proof has to last

03Move moneyPayments
Payments
KnightsPurse
Wallet & stablecoin payments
Live
Hold and send your money, invoice, and run a business — straight from your wallet.
  • Hold and send Bitcoin and stablecoins — keys stay on your device, not with us
  • Web, mobile app and browser extension, with built-in identity and payments; businesses can invoice and get paid directly
  • AI agents can be authorised to transact too — within limits you set

PQC Hosting + Bastion
Software supply chain
Live
Deploy, scan and prove your systems are quantum-safe.
  • PQC Host — signs every release and records it, so you have a build history nobody can quietly rewrite
  • Bastion — scans your code, dependencies and connections for old, breakable security, and produces reports for auditors
  • Show any third party your systems have been quantum-safe from a specific, provable date

05Settle and record itSettlement — the trust layer
Settlement
Armature L1
The trust layer
Live
The layer that records and finalises every action so it can't be faked or erased.
  • Every action is recorded with quantum-safe signatures — built in from the start, not bolted on
  • ~2-second final settlement, with a public record anyone can open and check
  • Carries identity, payments, signing and tokenised assets for people, institutions and AI alike

Trust Through Verification

Don't trust us. Check it yourself.

Everything you do here leaves a permanent receipt that anyone can verify — without going through KXCO. If we disappeared tomorrow, the proof would still stand.

A receipt nobody can forge
Every action carries a quantum-safe signature unique to whoever made it. (ML-DSA-65 on every action.)
Check it without us
Verify anything on the public record, or with free open-source tools. (No KXCO server in the path.)
Permanent and tamper-proof
Once it's recorded, it can't be quietly changed or deleted. (Anchored on Armature L1.)
Everyone is accountable
Every person, business and AI acts under an identity that can be checked. (Same standard for humans and machines.)
Proof beats promises.
Independently verifiable
Open-source verifiers
Public record
No central point of trust
Proof

Why you can believe all this.

Every claim here is backed by something you can check, a published standard, or named people. None of it asks you to just take our word.

Live infrastructure
It's running right now.
The public record at chain.kxco.ai is open to anyone. Every action is checkable — not locked inside a KXCO server.
Recognised standards
Built on the official rules.
All cryptography uses the NIST FIPS 203, 204 and 205 standards finalised in 2024 — the same ones regulated institutions are required to move to.
Open source
Audit the code yourself.
The post-quantum building blocks are published as open-source libraries (kxco on npm). Anyone can inspect the cryptography before relying on it.
Regulatory alignment
Pointed at the deadlines.
KXCO's baseline lines up with the G7's January 2026 roadmap (nonbinding), NIST transition guidance, and the NSA's CNSA 2.0 timeline.
Leadership
Real people behind it.
Founded by Shayne Heffernan Ph.D., with an advisory board drawn from BlackRock, Fidelity, DTCC, Bear Stearns and Capgemini. Full team at kxco.ai/corporate.
Usage metrics
Verifiable counters — coming soon.
We publish numbers only when you can confirm them yourself. Live, independently-checkable usage counters from the public record are on the way.
