What we collect, why.

We keep the waitlist small in scope on purpose. If you join, the information below is the only data we hold about you.

What we collect

• Email address. So we can send testnet invites and announcements.
• Optional wallet address. Only used to determine airdrop eligibility once mainnet criteria are published.
• Optional discovery source and experience level. Used in aggregate for marketing decisions; never linked to your name publicly.
• Referral code. A short identifier we generate from your email so friends you refer can be attributed.

What we don't do

• We don't sell your data.
• We don't share it with third parties beyond the email infrastructure provider that delivers your emails.
• We don't require KYC to join the waitlist. Token-related steps later may have their own legal requirements.

Analytics & cookies

If we add analytics to this site we'll use a privacy-friendly tool (e.g. Plausible) configured without cookies. If that changes, this page changes first.
