Ebook

The compact beginner guide

Same calm curriculum as Learn — straight through as an ebook. Pay on this site; Learn and Playground stay free.

  • 21 short chapters: why → custody early → how payments work → network → safety
  • Plain English — no hype, no buy tips, not financial advice
  • Pairs with free Playground modules when you want a visual deep dive

Educational only. We never ask for seed phrases, keys, or wallet passwords.

States to implement

Idle

Price + primary CTA. One ember button in view. Soft list of payment apps as reassurance, not a logo wall.

Checkout open

Peer embed or redirect. Calm copy: “Pay in the app you already use — we’ll unlock the download when it confirms.”

Pending verification

Waiting on Peer — do not unlock yet. Never ask for screenshots of seeds or wallet logins.

Success (ORDER_FULFILLED)

“Payment confirmed.” Primary action: download PDF/EPUB (signed URL). Secondary: Continue in Learn / Try Playground. No seed fields ever.

Failed / expired

Plain retry. Link back to free Learn so purchase friction never blocks learning.
