§Payment System & Zaps

pleb.school uses NIP-57 zaps for payments. Funds go directly to creators; the platform only verifies receipts.

§Two payment modes

§Tips

• Can be sent without a session if a signer is available
• Great for supporting free content

§Purchases

• Require an authenticated session
• Unlocks content once verified receipts meet the price
• Supports partial payments and installment zaps

§Claim behavior

• Auto-claim when receipts meet the price
• Manual “Unlock with past zaps” retry when needed
• Receipts are stored in the database for audit

§Admin notes

• Database price is authoritative; Nostr price is a hint
• Receipts are verified for signature, invoice hash, amount, recipient, and event match
• If receipts only appear on non-configured relays, claims can fail until relays are updated

Payments stay peer-to-peer while entitlements remain reliable.
