Sign Anything

Whether you’re signing off on a pitch deck, collaborating on an artistic project, or closing a top secret deal, our technology ensures privacy while being verifiable, and eliminates the risk of exposing personal information.

Privacy Preserving

By design, Csign can’t access your document. Signers privately share the secret codes (decryption keys) to interact with the document. Everything is encrypted from start to finish.

Our Advantage

Agreements published through Csign’s platform are private between signers, and rooted by a hash on a trusted public ledger. Csign transforms simple digital content into an authoritative source of truth.
