Offline-First Protocol

Payments that work
when the internet doesn't.

GhostPay Mesh is a cryptographic protocol for offline-first value transfer. Create, send, and settle payments — no connection required.

The internet fails. Payments shouldn't.

Billions of people and businesses are cut off from reliable payments every day — at festivals, in transit, during outages, and in developing markets.

Three steps. Zero connectivity.

GhostPay Mesh uses cryptographic promises to enable value transfer without any network connection.

Step 01

Create

Generate cryptographic payment promises offline. Each promise is signed, timestamped, and bound to your device.

Step 02

Transfer

Send payments via QR code, NFC, or Bluetooth. No servers, no internet — just peer-to-peer value exchange.

Step 03

Settle

When connectivity returns, the protocol auto-reconciles all transactions against the cryptographic ledger.

Military-grade cryptography.

Every transaction is protected by the same algorithms trusted by intelligence agencies and blockchain networks.

XChaCha20-Poly1305

AEAD encryption for payload confidentiality and integrity.

Ed25519 Signatures

Elliptic curve signatures for tamper-proof authentication.

Device-Bound Keys

Keys generated and stored on-device, never transmitted.

Zero-Knowledge Proofs

Prove commitment validity without revealing transaction data.

Built for the real world.

From festival crowds to disaster zones, GhostPay Mesh works where traditional payments fail.

Events & Festivals

Process thousands of payments when cell towers are overloaded.

Travel & Remote

Pay anywhere — planes, ships, rural areas, developing markets.

Emergency Relief

Distribute aid and process payments when infrastructure is down.

Business Continuity

Never stop processing — even during network outages.

Developer ready. Production proven.

Everything you need to integrate offline payments into your application.

REST API

Full-featured HTTP API with comprehensive documentation.

Mobile SDKs

Native SDKs for Flutter and React Native.

Protocol Spec

Complete cryptographic protocol specification.

// Create an offline payment promise
const promise = await ghostpay.createPromise({
  amount: 50.00,
  currency: 'USD',
  recipient: 'merchant_abc',
  offline: true,
});

// Transfer via QR code
const qr = await promise.toQR();

// Auto-settles when connectivity returns
promise.onSettle((receipt) => {
  console.log(`Settled: ${receipt.id}`);
});
