Shopstr

• Name: Shopstr
• URL: https://shopstr.market/
• Category: Nostr marketplace / self-custodial bitcoin commerce / Lightning-and-Cashu merchant layer
• Tags: bitcoin-ecosystem
• Summary: Shopstr is a Nostr-native Bitcoin market shell. The point is seller-controlled identity plus Lightning or Cashu checkout and wallet handoff. Useful commerce middleware, not a merchant-stack anchor.
• What it does:
  • Lets users buy and sell goods on a Nostr-based marketplace without traditional account approval or KYC onboarding
  • Settles payments directly between buyers and sellers over Bitcoin Lightning or Cashu rather than holding funds in platform custody
  • Gives buyers a built-in wallet option while still allowing funds to move to external wallets
  • Publishes product listings, reviews, wallet-connect behavior, media support, and relay-facing behavior through open Nostr standards
  • Ships as an open-source web application and progressive-web-app-style stack built with Next.js
• Key claims:
  • The homepage says “Sell anything. Get paid in Bitcoin. No bans, no fees, no middlemen,” and explicitly describes Shopstr as free to use, no-KYC, self-custodial, and open source
  • The homepage says shops cannot be banned or frozen because listings live on Nostr and users hold their own store keys, which is the clearest first-party sign that the project is built around user-controlled identity rather than platform accounts
  • The homepage says buyers pay with Bitcoin via Lightning or Cashu, money goes directly from buyer to seller, no platform holds funds, and sellers face no mandatory fee beyond an optional donation rate
  • The homepage’s FAQ says no external wallet is required because Shopstr includes a built-in wallet, but users can withdraw to an external wallet at any time
  • The homepage reports 13M+ sats in sales volume and says there are no mandatory platform fees, reinforcing that Shopstr is operating a live marketplace rather than only a protocol demo
  • The README describes Shopstr as “A global, permissionless Nostr marketplace for Bitcoin commerce” and lists support for NIP-47 Wallet Connect, NIP-60 Cashu Wallet, NIP-99 Classified Listings, NIP-85 Reviews, NIP-46 Nostr Remote Signing, NIP-57 Lightning Zaps, and Blossom media support, which indicates a fairly broad commerce-and-wallet protocol surface
  • The package manifest includes nostr-tools, @cashu/cashu-ts, @getalby/sdk, @getalby/lightning-tools, next, and @ducanh2912/next-pwa, which is consistent with a Nostr-native web commerce app that integrates wallet and ecash tooling rather than a static marketplace brochure
• Whitepaper: No canonical standalone Shopstr whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, public README, and package manifest in the first-party repo; see ../whitepapers/shopstr-primary-sources-2026-05-02.md.

Internal linkages

• Ecash rail baseline: cashu.

• Merchant-software contrast when the point is checkout plumbing rather than Nostr-native discovery: btcpay-server.
