Blood Seal Gu

Signaturly → PactDoc — e-signature & document workflow

Most agreements in India are still print, sign, scan, email — with no proof of who signed what, or when.

Ability

What it does

A secure digital-signature and document workflow, built India-first, with ready-made templates for rentals, housing societies, HR and small firms.

  • Three apps: Express API, React signing app and an admin for users, plans and templates.
  • Sealed PDFs and a chained audit log record who signed what, and when.
  • Team workspaces with roles; an access test calls every one of a team’s 53 routes as outsider, viewer, member, admin and owner.
  • Public API with keys and webhooks, embedded signing, and Razorpay billing.
  • The server refuses to start if any secret is missing or still a placeholder.

Feeding

Inputs & upkeep

A Gu that isn’t fed starves. This one needs:

Eats
Documents, signer identities, email links and codes
Upkeep
Templates and data migrations as plans change
If starved
No mail server? Emails print to the server terminal — still usable for local work
