Secure, compliant CoinEx API & protocol integration — from market feed to settlement

We deliver fully documented, testable API implementations and integration kits for market data ingestion, order routing, wallet reconciliation, proof-of-reserves verification and KYC/AML-ready pipelines tailored to CoinEx or similar exchanges.

Market Data & Streaming — WebSocket client for real-time ticks, orderbook snapshots, incremental updates (diffs) and historical charting export (CSV/Parquet).

Trading & Order Management — Authorized REST endpoints and signed private endpoints (HMAC) for limit/market orders, OCO, margin and futures wrappers with idempotency and retry logic.

Custody & Reconciliation — Automated on-chain wallet reconciliation, Merkle-tree proof verification (proof-of-reserves), and scheduled accounting exports for ledger ingestion.

Compliance & Risk — KYC/AML gateway design, sanctions screening hooks, rate-limit management and secure secrets handling (HSM / KMS integration).

Deliverables & Integration Packages

Standard Integration

OpenAPI (Swagger) spec for public & private endpoints
REST client + WebSocket client (Node.js and Python)
Authentication & signing helpers (HMAC with nonce, timestamp)
Basic reconciliation script (wallet <-> on-chain)
Integration test plan & Postman collection

Advanced (+Compliance)

Full trading gateway (order manager, risk checks, idempotency)
Proof-of-reserves verifier (Merkle-tree checks & on-chain proofs)
KYC/AML adapter (screening, audit logs, PII minimization)
Deployment guide: API gateway, rate-limiting, HSM / KMS

Enterprise

Custom SDKs (Go, Java, .NET) and sample microservices
High-availability WebSocket ingestion with checkpointing
Ledger export, GL mapping & tax-ready reporting
Onsite protocol analysis / third-party audit support

Integration Quick-Start (Example)

// PSEUDOCODE: REST auth & private request (HMAC-based)
POST /api/v1/auth/token
{ 'api_key': 'YOUR_KEY', 'nonce': 1690000000000 }

// Sign requests: signature = HMAC_SHA256(api_secret, method+path+body+timestamp)
GET /api/v1/orderbook?symbol=BTCUSDT
Headers:
  X-API-KEY: YOUR_KEY
  X-SIGNATURE: <signature>
  X-TIMESTAMP: <ts>

// WebSocket: subscribe to trades & diff orderbook
wss://ws.coinex.example/stream
subscribe { 'method': 'subscribe', 'channels': ['tickers','orderbook'] }

Sample Market-reconciliation Flow

1) Ingest WebSocket snapshots + diffs and persist with sequence IDs.
2) Periodic full-orderbook snapshot (S3/Parquet) for replays.
3) Reconcile exchange wallet balances against on-chain transactions (addresses & deposits).
4) Verify platform-stated reserves using Merkle proofs published on-chain / public endpoint.

Core Benefits of Our Integration

Production-ready SDKs & OpenAPI documentation for fast go-live
Secure secrets handling (KMS/HSM integration) and automated key rotation
Compliance-first design: KYC hooks, consent logging, and data minimization
Scalable real-time ingestion with checkpoints and replayability
Transparent proofs-of-reserve verification assistance (Merkle tree)

Regulatory & Security Notes

We implement integrations only via authorized, lawful channels. For crypto-exchange projects, we provide guidance for AML/KYC workflows, sanctions screening, and regional regulatory requirements (e.g. FCA, ASIC, MAS, FinCEN guidance). We never assist with illicit activity and replace unsafe terms like 'crack' with 'reverse engineering' when documenting interoperability analysis.

API Integration Instructions (recommended)

Provide the target app name (CoinEx) and detailed scope (market data, trading, settlement, reserve verification).
Share any official API keys / sandbox credentials or request our sandbox setup.
We perform protocol analysis (2–5 business days) and produce OpenAPI + SDKs.
Integrate & test in staging: WebSocket resiliency testing, rate-limit handling and order idempotency.
Deliver: source code, API docs, test plan, compliance checklist and runbook for production.

Typical small-scope delivery: 3–8 business days. Complex enterprise or custody work quoted separately.
