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 trust 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 JackKXCO on GitHub.

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.
