Distributed ledger: finance records every party can verify

When invoices, payments and trade documents move between organisations, everyone needs to trust that nothing was changed. We build distributed ledger systems that make finance and trade records tamper-evident, without handing your data to a third party.

What it solves

Tamper-evident invoices

Verify that a supplier document has not been altered between receipt, approval and payment.

Zero-trust trade records

Each trade partner runs its own ledger node in its own cloud environment; no single party controls the record.

Verified identities

Public key infrastructure and cryptographic signatures prove who sent what, and secure every exchange.

Key management

Per-participant encryption keys with secure storage and key functions, so data stays readable only by those entitled to it.

Plugged into your AP automation

The trust layer records each step of the invoice journey (received, approved, paid), so audits and supplier disputes are settled against a record nobody can quietly edit.

Our zero-trust trade registry, built over two years, is in use across port and customer networks in Southeast Asia. It took more than 5,000 engineering hours and connects every party in an import or export: importers, exporters, banks, customs, ports and shipping lines. It includes private and shared registries, desktop key wallets, PKI key management and an API gateway with identity management.

Frequently asked questions

What does tamper-evident mean for invoices?

Each step of an invoice's journey, from receipt to approval and payment, is recorded so that any later change to the document or record can be detected.

Does one party control the ledger?

No. In a zero-trust setup each partner runs its own ledger node in its own cloud environment, so no single party controls the record.
