OpenData · OpenFinance · Identity as a Service · Protocol Analysis

Securely connect World ID with the Digital USD wallet to your platform

We provide a complete interface implementation and source code delivery for World App protocol-based authentication, message signature verification, USDC on/off-ramp access, and Mini App integration, with compliance and privacy considerations.

Proof-of-Human (World ID) integration — Verify World ID's zero-knowledge proofs or signatures, enabling unique verification and session binding while preserving anonymity.
Digital USD (USDC) wallet integration — View balance, initiate transfers, fetch transaction history and export compliant reports (CSV/JSON/PDF). Support fiat on/off-ramp via regulated channels.
Mini App / SDK integration — Embedded mini-app ecosystem integration, event subscription, message verification and callback handling, supporting Android / iOS / Web.
Compliance & risk guidance — AML/KYC process consulting, data minimization strategies and cross-border transfer compliance roadmap.

Deliverables and Examples

What We'll Deliver

  • Protocol analysis report (authentication, signing model, callbacks and security boundaries)
  • Runnable API source code (Node.js / Python) and SDK templates (Android / iOS / Web)
  • OpenAPI documentation, sample requests/responses
  • Automated tests and integration plans
  • Compliance guidance (data residency, cross-border transfers, KYC/AML integration)
  • Deployment instructions and production security checklist

Example: Initiate USDC Transfer (pseudo-code)

// POST /api/v1/world/transfer
// Authorization: Bearer <SERVICE_TOKEN>
{
  'from_wallet': '0xAB...123',
  'to_wallet': '0xCD...789',
  'amount_usdc': 25.00,
  'memo': 'invoice-2025-09-01',
  'idempotency_key': 'uuid-xxxx'
}

Response: {
  'status': 'queued',
  'tx_reference': 'chain-tx-hash-or-provider-id',
  'estimated_settlement': '2025-10-01T12:00:00Z'
}

Identity Verification Example: World ID

// Server-side verification flow (outline) 1. Client uses World App to generate a proof or signature (Proof / Signature). 2. Post the proof/signature with user session data to the backend verification endpoint. 3. Backend calls World verification library or verifier node to confirm uniqueness and timestamp. 4. Map the verification result to a minimal user identifier for the app (do not store reversible biometric data).
