Plaza is the point-of-sale that accepts Lightning — the fastest payment rail on earth. Your customers scan a QR code. You keep 100%. Visa, but free.
No bank approval. No Square rep. Just you, your wallet, and Plaza.
Free on iOS and Android. Connect your Lightning wallet via NWC — Plaza generates invoices but never holds your keys. Your wallet, your sats.
Show the QR code. Customers pay from Cash App, Phoenix, Strike, Alby — any Lightning wallet they already have.
Payment settles in seconds. Zero fees deducted. A Schnorr-signed receipt is stored on Blossom automatically — verifiable proof, forever.
Merchants run their business. Customers discover where to spend. Both sides sovereign.
Everything you need to run your counter — and understand your business.
Google Maps for Bitcoin commerce. Find merchants. Pay sovereign.
Open source isn't enough. The question is: can you run it without trusting us?
Published in the public domain. SHA-256 verified. Defensible prior art. Anyone can build on it.
Plaza generates invoices — never holds keys. Your wallet signs. Mathematically impossible for Plaza to take your funds.
Your merchant profile is a keypair you own. Plaza disappears? Your identity stays — portable to any Nostr client.
Every transaction generates a Schnorr-signed receipt stored on Blossom. Verifiable proof of commerce, forever.
Phoenixd + LNbits + Caddy on your own VPS. Plaza's backend is a reference, not a dependency.
Lightning, Nostr, NWC, NIP-15, Blossom. All open. All auditable. Your catalog lives on Nostr — readable by humans and agents alike.
Each transaction produces a Schnorr-signed receipt, stored on Blossom — open, content-addressed media servers. Not a database row Plaza controls. A cryptographic artifact anyone can verify and no one can alter.
Your sales history belongs to mathematics, not to a platform. If Plaza vanished tomorrow, every receipt would still verify.
Example receipt. Every field verifiable against the merchant's public key.
Self-sovereign. Zero fees. Runs indefinitely. No custodian in the critical path. Your Lightning wallet is yours forever — whether Plaza exists or not.
Zero transaction fees. Zero subscription fees. Every feature included. No paywalls, no tiers, no catches.
0% transaction fees. 0% subscription fees. Always.
