Tonkeeper Integration & Protocol Implementation Services (OpenFinance · TON)

Code & Documentation

• runnable integration source code (Node.js/TypeScript or Python)
• OpenAPI / Swagger interface descriptions and sample requests
• Deployment guides, test cases, and CI configuration
• Compliance guidance (privacy, key management, data minimization)

Functional Modules

• Wallet login (signature challenge → verification → session token)
• Address balance and token (TON / TIP-3) synchronizer
• Transaction indexer with Webhook / SSE real-time pushes
• Batch reconciliation reports (CSV / Excel / JSON) export
• NFT transfers and metadata harvesting

Example Code (Pseudo)

// Example: Wallet Sign-in (pseudo-code)
// 1. Backend generates a challenge and returns it
POST /auth/challenge
Response: { "challenge":"random-hex-123" }

// 2. Client signs the challenge with Tonkeeper (within the wallet)
// 3. Client submits signature and address to backend
POST /auth/verify
{
  "address":"EQC...",
  "signature":"base64-sig",
  "challenge":"random-hex-123"
}

// 4. Backend validates the signature and issues a session token
Response: { "access_token":"ey...", "expires_in":3600 }

// Transaction monitoring example (using ton-client or tonweb)
// Start listening: subscribe to address tx, event, map to Webhook or message queue

API Integration Guidance (Overview)

1. Use wallet signing challenges (challenge-response) for login; backend stores only session tokens and does not hold private keys.
2. Fetch transactions and balances from nodes or light clients via TON RPC / ton-client-js, with deduplication and retry logic in the indexer.
3. For high-volume events, use queues (Kafka / RabbitMQ) and idempotent Webhook callbacks with replay protection and signature verification.
4. Sensitive operations (withdrawals, bulk issuances) are signed on the client; backend only handles verification and broadcast.
5. Compliance layer logs user consent and timestamps, and implements data minimization retention policies.

Example Endpoints (Pseudo API)

GET /api/v1/ton/balance?address=EQC...
Authorization: Bearer <ACCESS_TOKEN>

POST /api/v1/ton/subscribe
{ "address":"EQC...", "webhook":"https://your.service/hook" }

POST /api/v1/ton/broadcast
{ "boc":"BASE64_BOC", "signed_by":"wallet" }

Compliance & Security Highlights

• Non-custodial design: private keys/mnemonics never uploaded to the server; all signing occurs on the user device or within Tonkeeper.
• Transport encryption: TLS for all APIs; Webhooks support HMAC signature verification.
• Logging & auditing: optional audit log export and access controls.
• Privacy: recommended data minimization and retention policies; supports on-premise deployment and data isolation where needed.

Delivery Timeline Example

Typical flow: Requirements confirmation (1-2 days) → Protocol & API design (2-5 days) → Development & internal testing (3-10 days) → Delivery & sample deployment (1-3 days). Adjusted by project complexity.
