0 / 80 chars — free tier
Free tier. Posts under 80 characters are minted by the site operator’s wallet — no wallet, no gas needed from you. The token is held by the operator; the timestamp and text are yours, on-chain forever. Passes automated moderation and a gas-price check (mint() is skipped if network fees spike).
