Developers

# Build on infrastructure anyone can verify.

Sign, verify, settle and issue identities, for people and AI agents, using open-source post-quantum tools and a live network. No lock-in: everything you produce can be checked independently, with or without KXCO.

What you can build

## The whole stack, as building blocks.

Post-quantum signing & verify

Add ML-DSA-65 signatures and verification to any app or webhook, with libraries for JS, Python, Rust and Go.

Identity for humans & agents

Issue verifiable identities and credentials, the same API for people, organisations and AI agents.

Settle on Armature L1

Read and write to a live post-quantum network with ~2-second finality and a public explorer over standard EVM tooling.

Encrypted data & transport

ML-KEM-768 key encapsulation and file encryption, plus hybrid post-quantum TLS for connections.

Attest your deployments

Sign every release and scan for quantum-vulnerable algorithms with PQC Host + Bastion in your CI/CD.

Authorise AI agents

Give agents per-request signed authentication (no bearer tokens) and wallets governed by their own keys.

Open-source packages

## Audit it before you trust it.

All published under @kxco on npm and KnightsbridgeAIQ on GitHub . All sixteen packages, with versions and evidence .

kxco-post-quantum

ML-DSA-65 and ML-KEM-768 primitives, signatures, key encapsulation, key derivation.

kxco-verify

Browser- and server-side verifier for any KXCO signature. Runs with no KXCO server. JS / Python / Rust / Go.

kxco-post-quantum-webhook

Signed-webhook adapters for Express, Fastify, Hono, Workers and Vercel.

kxco-pq-vault

Post-quantum file encryption (ML-KEM-768 + AES-256-GCM).

AI-agent quickstart

## Give an agent an identity and a wallet.

# 1 · generate a post-quantum keypair for your agent

npx kxco-pq keygen --algo ml-dsa-65 --out agent-identity

# 2 · connect to the Armature L1 network

# live RPC + current chain ID: https://chain.kxco.ai

# native token: ARMR

# 3 · sign every request, no bearer tokens, server stores only the public key

import { sign , verify } from 'kxco-post-quantum'

const sig = sign (request, agentSecretKey) // attach to the request

verify (request, sig, agentPublicKey) // anyone can check it

Full agent documentation, wallet API and the published KXCO public key are at chain.kxco.ai . Always read the live network parameters there before integrating. For the complete walkthrough, identity, signing, settlement, hosting and quantum readiness, read Running AI Agents on KXCO .

Latest writing

## The long reads.

Running AI Agents on KXCO

Give an agent a post-quantum identity, sign every action, settle on Armature L1, host it and make it quantum-ready, with runnable code. ~40 min read.

Quantum Risk Went Institutional

BlackRock's quantum warning, the two on-chain risk vectors, and why Armature L1 is post-quantum from genesis, coordinated by the ontology. ~22 min read.
