Who we serve
Own your money and hold the keys yourself
Hold your own Bitcoin and stablecoins under your own keys, sign with a post-quantum key, and have a document attested so anyone can check it. You hold the keys, so KXCO cannot lock you out of your own wallet.
Built on post-quantum cryptography
Your wallet ID and your signatures use post-quantum cryptography, designed to stay genuine and provable as quantum computers arrive.
Yours, and provably yours
- Hold your own money. Bitcoin and stablecoins in a KXCO Sovereign self-custody wallet, where the keys live on your device, not with us and not with a bank.
- Your own post-quantum ID. Your wallet derives a KXCO ID from your own ML-DSA key, so you can prove which key is yours. Identity for people is live, through KXCO Herald.
- Documents anyone can check. Herald Verify records a signed, revocable attestation of a document on Armature, and anyone can check it without asking KXCO.
You are in control, and you can prove it
- Self-custody: you hold the keys, so KXCO cannot freeze or seize your funds.
- Your ID comes from your own key, not from an account in a company database.
- Post-quantum by design, so what you sign today stays provable for the long term.
- Anyone can verify your signatures independently, with no KXCO account needed.
Licensed institutions hold assets. KXCO supplies the software.
