Live peer-to-peer Bitcoin order book aggregated from Nostr relays.
Live site: https://p2psats.com
P2P sats is a read-only aggregator of peer-to-peer Bitcoin orders. It connects to public Nostr relays where platforms like RoboSats, HodlHodl lnp2pbot, Mostro and Peach broadcast their offers under NIP-69, parses the events, and renders everything as a unified order book with depth chart, spread, and crossed-pair detection.
No accounts. No orders posted from here. No funds touched. Just a window into what's already public on the relays.
The P2P Bitcoin market is fragmented. Liquidity, prices, and payment methods are spread across separate apps and bots, each with its own siloed slice of the order flow. To find the best ask you currently have to flip between four different UIs. Most people just don't bother, and liquidity stays thin where it could be deep.
P2P sats unifies the view to (hopefully) make the market stronger, especially for users in regions where non-KYC and local payment methods are essential.
- Live aggregation from four NIP-69 relays (Mostro, lnp2pbot, RoboSats, Peach)
- Depth chart with bid/ask area and a Yadio reference price line
- Spread, mid-price, best bid/ask, total depth on both sides
- Crossed-pair detection (cross-platform arbitrage candidates)
- 9 quote currencies (USD, EUR, BRL, ARS, MXN, VES, ZAR, RUB, PEN)
- 3 locales: English, Spanish (es-419), Brazilian Portuguese (pt-BR)
- Statically prerendered (vite-ssg) for fast first paint and SEO
- Mobile-friendly responsive layout

Adding a new platform is mostly a matter of identifying its NIP-69 relay and adding it to src/lib/data.ts. PRs welcome.
Requires Node 22.12+ (see .nvmrc).

Issues and PRs welcome. Easy first contributions:
- Add a new NIP-69 relay (
src/lib/data.ts,src/services/nostrOrderbook.ts) - Add a payment-method label (
src/lib/data.ts) - Translation improvements (
src/i18n/locales/*.json) - Bug reports for anything that looks wrong in the order data
Before opening a PR, please run npm run type-check && npm run build so the prerender still passes.
- p2p.band by KoalaSat does something very similar. P2P sats was built independently; the more frontends on this public data, the better.
- The NIP-69 spec, without which none of this would exist.
- The RoboSats, lnp2pbot, Mostro and Peach teams, for publishing their order data openly to Nostr.
