securely integrate World ID and the Digital USD wallet into your platform

We provide end-to-end API implementations for World App, including identity verification, message signature checks, USDC on/off‑ramp, and Mini App integration, with compliance and privacy safeguards.

Proof-of-Human (World ID) integration — verify World ID using zero-knowledge proofs or signatures, enabling anonymous yet unique verification and session binding.
USDC Wallet integration — view balances, initiate transfers, fetch transactions and export compliant ledgers (CSV/JSON/PDF). Supports fiat on/off‑ramp via regulated channels.
Mini App / SDK integration — embedded mini-app ecosystem access, event subscriptions, message validation and callbacks for Android / iOS / Web.
Compliance & risk guidance — AML/KYC consulting, data minimization strategies, and cross-border transfer compliance roadmaps.

Deliverables & Examples

Standard Deliverables

  • OpenAPI / Swagger documentation and sample requests
  • Protocol and authorization flow analysis (Token, Session, Signature)
  • Runnable backend sample code (Node.js / Python) and SDK samples
  • Webhook and async notification middleware
  • Automation tests and deployment guidance
  • Privacy and compliance recommendations (data minimization, logs, consent)

Example: Initiate USDC Transfer

// 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 (high level) 1. Client uses World App to generate a proof or signature. 2. Post the proof/signature with user session data to a verification endpoint. 3. Back-end calls World verification library or node to confirm uniqueness and timestamp. 4. Map the result to a minimal user identifier (no reversible biometric data stored).

Key Benefits

  • Privacy-first: data minimization, anonymous verification and de-identification
  • Cross-platform: Android / iOS / Web references and SDKs
  • Compliance-ready: KYC/AML integration and audit-ready logs
  • Rapid deployment: first version delivered within 5–12 business days after analysis
  • Transparent pricing: starting at $300, pay on delivery acceptance

典型 Integration Modules

  • World ID proof verification and session binding
  • USDC balance checks, transfers, and callback handling
  • Mini App events, authorization and message signature verification
  • Fiat on/off ramp integration and reconciliation workflows

API Integration Quick Start

  1. Provide target App name and use case (e.g., World ID login, USDC on/off ramp, Mini App payments)
  2. Protocol scan and sandbox suitability evaluation (you may provide test accounts or official sandbox if needed)
  3. Design authorization flow (OAuth2 PKCE + Refresh Token + Webhook verification) and deliver secure implementation
  4. Development and internal validation (including idempotency, resume on failure, and notifications)
  5. Deliver: OpenAPI docs, sample backend, automated tests and deployment guidance

About Our Studio

We are a boutique studio focused on mobile app protocol analysis and compliant API integrations. Our team blends fintech, security and cloud-native expertise to deliver ready-to-deploy API implementations with OpenAPI documentation and automated tests.

  • OpenData/OpenFinance integrations and cross-platform support
  • OpenAPI/SDK deliveries and testing scripts
  • Transparent pricing: starting at $300 with flexible payment on delivery

Typical Collaboration Process

  1. You submit the target App and use case (e.g., Yape, World App, etc.).
  2. We perform feasibility and compliance risk assessment (1-3 business days).
  3. Design the API and security approach; generate OpenAPI specs (2-6 days).
  4. Develop and validate internally; deliver runnable samples and tests (3-10 days).
  5. Deliver source code, docs and test assets; provide go-live support (optional).

FAQ

What information do I need to provide?

Please provide: target App name and version, concrete use cases (transactions, onboarding, etc.), any test credentials or production access, and compliance or auditing requirements.

How to ensure compliance?

All work is performed under client authorization or publicly available APIs; we provide data minimization guidance, logging/audit strategies, and can sign NDA if needed.

World App — Official Features Summary

World is a global network built on privacy-preserving Proof‑of‑Human technology, designed to enable universal access to digital assets and decentralized services. World App provides a mobile gateway to World Network, with secure World ID storage, digital asset usage, and access to the Mini App ecosystem.

Main Features
  • World ID / Proof of Human: a digital credential that proves a unique person online in a privacy-preserving way, stored on-device for anonymous yet trusted identity verification across platforms and World App Mini Apps.
  • Storage & Transfer of Digital USD (USDC): wallet holds USDC and can be funded or withdrawn through licensed partners; instant, free transfers to global users.
  • Gas-free Experience: zero-GAS transactions for verified World ID users, with 24/7 chat support.
