Tenet / 01
Audit-grade by default
Every signature creates a cryptographically verifiable receipt. No upsell, no premium tier — the chain is the product.
Studio · Index
A signing system, not a signature pad.
Puresign builds the simplest legal kernel for documents that matter. Manifest, frame, verify, archive — four blocks, one chain.
Tenets · MMXXVI
Four blocks, no detours.
Most signing tools ship a thousand features and one good receipt. We do the opposite — one clean signing flow, and a receipt that holds up the next day, the next year, the next decade.
Tenet / 02
No paper theatre
We don't ask you to print, scan, fax, or rotate a PDF. Type your name, pick a style, ship the block. That's it.
Tenet / 03
Email verified, always
Every signer confirms a real inbox before reaching a block. Anti-fraud isn't a feature — it's a precondition.
Tenet / 04
EU-tenanted
Your tenant lives in the EU by default. GDPR isn't a checkbox, it's where the database actually runs.

We ship from a small team, on a clean stack, without ads, without surveillance pixels, without a data-resale model. The chain pays the bills — and only the chain.
