← The High Quality Terminal UI Cookbook

The PDF, $1

11 chapters, typeset, yours to keep. The same book is free to read on this site and free as an EPUB, and nothing in the PDF is missing from either. A dollar is for the typesetting and for keeping the lights on.

Fifteen chains. USDC on Solana is the default because a network fee should not cost more than the book.

How it works

  1. 1. You pick a chain and CoinPay shows you an address and an amount.
  2. 2. You pay it. CoinPay tells us when it confirms.
  3. 3. You get a download link that works for 48 hours. Lost it? Pay nothing again, just email us the payment id.

No account, no email required, no card. We never see a wallet key, and the payment settles to us directly rather than sitting in an escrow.
