NIP-QUOTE (kinds 30530, 30531): structured pricing for Nostr.

NIP-99 gives you classified listings with a price tag. NIP-QUOTE gives you the negotiation layer. A provider publishes a structured quote with line items, tax, validity window, and payment method options. Multiple providers can quote the same request. Once accepted, Payment Terms (kind 30531) lock in the deal: milestones, deposits, streaming rates, cancellation schedules.

NIP-ESCROW (kinds 30532, 30533, 30535): conditional payment coordination.

NIP-57 zaps are one-way. Cashu tokens are bearer instruments. Neither gives you "hold these funds until both sides are happy."

Lock (30532) commits funds with proof. Settlement (30533) covers all outcomes via a single outcome tag: released, forfeited, partial_forfeit, or expired. Payment Receipt (30535) proves money moved; also handles streaming payments via tick_number and cumulative tags for time-based billing.

Payment-rail-agnostic. Events record what happened; money moves on Lightning, Cashu, Strike, Stripe, or whatever rail the parties choose.

Build with this: a freelance platform with milestone-based payments and per-deliverable quotes. A peer-to-peer marketplace with buyer protection. A ridesharing app with per-minute streaming receipts.

Published 20 more Nostr protocol extensions on NostrHub, plus updates to 2 from last week. The full portfolio is now 27 standalone NIPs covering payments, trust, scheduling, disputes, provenance, and more. 40 new event kinds total.

Payments: NIP-QUOTE (structured pricing), NIP-ESCROW (conditional payments with settlement outcomes), NIP-INVOICING (machine-readable invoices)

Trust: NIP-TRUST (portable trust networks with revocation), NIP-REPUTATION (structured ratings), NIP-DISPUTES (dispute resolution with mediator support)

Scheduling: NIP-BOOKING (calendar availability and slot booking), NIP-PROVIDER-PROFILES (service provider discovery)

Ecosystem: NIP-CRAFTS (technique documentation), NIP-PROVENANCE (supply chain tracking), NIP-SCARCITY (workforce shortage signals), NIP-MENTORSHIP (training progression)

Paid APIs: NIP-L402-SERVICES (Lightning-gated API discovery, 8 production implementations)

Three composition guides show how existing NIPs combine without new kinds: SLA monitoring, community governance, institutional referral routing.

All standalone. No framework lock-in. Every NIP works independently.

Authorship verified with NIP-VA (kind 31000) attestations.
