Sign without friction
Recipients sign on any smartphone, tablet, or desktop. Our interface is designed for speed and clarity.
Seal the proof
The moment everyone signs, the document is sealed and its cryptographic fingerprint is anchored on the blockchain.
Why does blockchain proof matter?
Encryption protects a document while it travels, but it says nothing about which version was signed once the file has been forwarded, renamed, and stored in multiple places. Firma anchors the fingerprint of the sealed PDF on a blockchain. This means the person holding the file can independently prove which bytes were signed long after the deal closed.
Sealed PDF
The PDF itself contains a cryptographic certificate embedded in the metadata.
Anchored
The document's hash is stored on a public ledger that can't be edited or deleted.
Impossible to Fake
Any change to a single pixel of the document invalidates the blockchain proof instantly.
Universal Verification
Verify any document years later using our open verification portal, independent of our system.
