Institutional Metrics

Built to the standards your risk committee already applies

Sub-200ms Transaction Latency

Persistent operator sessions and pre-warmed routes keep median dispense time under 200ms end-to-end, including ledger commit.

Intelligent Carrier Failover

Health-scored dealer rails re-route in-flight traffic away from degraded operator connections before your customers see a failure.

Bank-Grade Financial Reconciliation

Double-entry, immutable ledger reconciling core-banking debits against MNO fulfillment receipts continuously, not nightly.

Secure Integration

Mutual TLS, AES-256, and an audit trail your regulator can read

mTLS-pinned channels

Every institution connects over mutually authenticated TLS 1.3 with certificate pinning and per-environment fingerprints.

AES-256 at rest, tokenised PII

Subscriber identifiers are tokenised on ingress; payloads and ledger entries are encrypted with rotating AES-256 keys.

Immutable transaction evidence

Signed, append-only records for every leg of a purchase — exportable for dispute resolution and audit.
