Tessera

A browser app to create, browse, respond to, and tally on-chain surveys and polls on Cardano, implementing CIP-179 (transaction metadata label 17).

Surveys live entirely in transaction metadata — no smart contracts, no custom backend required to read them. Responses can be public or sealed (timelock-encrypted with drand for delayed reveal), eligibility is scoped by on-chain role (DRep, SPO, CC, Stakeholder, Keyholder), and tallies are computed client-side directly from chain data.

Status: active development, end to end. The app covers the whole survey lifecycle, and the Tier-1 serving backend validates responses, snapshots stake/voting-power weights at each survey's end epoch, and finalizes closed surveys into content-addressed result artifacts that anyone can re-derive from chain data with packages/verifier (docs/AUDIT.md). See backend/ARCHITECTURE.md for the design and backend/TALLY-SPEC.md for the counting rules.

Governance linkage

A survey can be advertised by a Conway governance action (CIP-179 Action → Survey linkage): the action's anchor metadata carries the survey's ref, and Tessera surfaces the link on the explore and survey pages once the action's voting deadline matches the survey's end epoch.

The survey page offers its owner, and anyone in Pro mode, a link tool at /survey/:key/link that produces the linked CIP-108 anchor document — from a minimal built-in form, or by inserting the link (and its @context terms) into a document your governance tooling produced. It states the one epoch the action must be proposed in, with dates; hashes the exact emitted bytes and pins them to your configured IPFS providers (or you host them yourself) so the served document matches the on-chain hash; and can build, sign, and submit an Info Action carrying the anchor from a CIP-30 wallet. For other action kinds, take the document, hash, and URL to your own tooling.
