BlockDex/Security

Security

What BlockDex stores, who else processes it, and how to report a vulnerability.

Reporting a vulnerability

Email hello@kynth.studio. Include the URL, what you did, and what you saw. There is no bounty and no NDA to sign. We will confirm receipt, and we will tell you what we changed.

The same address, with a machine-readable expiry, is published at /.well-known/security.txt under RFC 9116.

Accounts

BlockDex has no user accounts. There is nothing to sign in to, no password to reset and no session to steal — the site is a published dataset and a set of static pages, and a build gate fails the deploy if an authentication route ever appears while this page still says otherwise.

What is stored

  • An email address, only if you type one into the subscribe form, and only after you confirm it by clicking a link.
  • Anonymous page analytics with the IP address truncated before it is stored.

Who else processes data

  • Vercel — hosting and edge delivery; request logs
  • Supabase — the database this product's own index is served from
  • PostHog — product analytics, IP-truncated
  • Resend — delivering the one email the subscribe form sends

Also true

  • Everything on this site is generated from public sources and rendered as static pages; there is no user-generated content that another visitor can see.
  • The whole estate runs on one Supabase project with row-level security on; this product's tables are its own.

BlockDex is built and run by Kynth Studios. The declarations on this page are part of this product's own configuration and are re-checked at every deploy against the repository they describe: a product that claims to have no accounts and ships an authentication route fails the build, and so does one that takes payment without naming its payment processor here.

The studio list

One product, taken apart, once a month

Kynth Studios pulls one shipped product open every month — what it does, what it cost to build, what the pipeline behind it looks like, and what the numbers did. One email a month, nothing in between.

Double opt-in — we send one confirmation link and nothing else until you click it.
