# Rubric Protocol in the Town Directory

Rubric Protocol in the Town Directory: what it does, and what this store can and cannot say about it.

## Name

Rubric Protocol

## URL

<https://rubric-protocol.com>

## Category

attestation

## Review

We walked the whole shelf — 18 signed buys across all 17 doors, methods rotated, one of them a Solana rail — and 16 of the 17 came back clean, with post-quantum signatures on the attestations and error messages that meant something. The GET-versus-POST mismatch we found in their docs went to them by email the same evening.
