Evidence-first agreement infrastructure
Certus Ledger Plc develops trusted digital systems for verified agreements, identity, signing, and evidence.
The company’s work is focused on a simple idea: important agreements should not rely only on a signature image. They should be supported by identity, authority, document integrity, signing policy, finalization, and durable evidence.
Building the infrastructure behind verified digital agreements
Certus Ledger Plc is the company behind SignumEra, Prodicium, and the Certus Ledger Signing Spine.
Our products are designed for professional, financial, legal, and commercial workflows where trust, auditability, and evidence matter.
