Settlement Infrastructure
for Institutional FX
KXCO Armature is a private, permissioned Layer 1 blockchain built for cross-border payments at institutional scale. Post-quantum secured. OTC-native. Audit-ready on day one.
Built for institutions, not retail
Post-Quantum Secure
Every transaction is signed with ML-DSA-65 (CRYSTALS-Dilithium), a NIST-standardised post-quantum signature scheme. The network is quantum-resistant from day one. No future upgrade required. KXCO is dedicated to staying ahead of the quantum AI revolution.
OTC-Native Settlement
Rates are set directly from OTC desk quotes — no public order book exposure, no slippage. The operator locks a corridor rate (ARMR per unit of fiat) and it is applied immutably to each payment instruction.
Compliance by Design
Every admin action, rate lock, and payment carries a full audit trail. Correspondent account ledgers record debits and credits on every settlement. ISO 20022-compatible statements available on request.
Three steps from instruction to settlement
Connect
The institution connects via REST API or the admin portal and submits a payment instruction in their fiat currency — USD, EUR, GBP, AED, SGD, HKD, JPY, CNY, CHF, DKK, or BTN.
Rate Lock
The operator applies a pre-locked exchange rate derived from OTC desk quotes and live FX reference data. The corridor rate is fixed at the point of instruction — no market exposure during settlement.
Settle
The payment settles on-chain in ARMR with deterministic finality. The institution receives a confirmation with a full audit trail and an ISO 20022-compatible account statement on request.
