Envoy API Integration & OpenFinance Services

Comprehensive Transaction Tracking

Our integration enables deep access to Envoy's transaction ledger. You can retrieve automated updates on all Bitcoin transfers, complete with TXIDs and block confirmations. This level of detail is critical for tax reconciliation and strict financial accounting where every satoshi must be documented.

Account & Balance Synchronization

Envoy supports managing both mobile hot wallets and Passport hardware wallet accounts. Our OpenData API bridges this gap, automatically syncing the balances of all configured accounts so your external treasury dashboards always reflect accurate, up-to-the-minute fiat and BTC valuations.

Coin Control & Tagging Analysis

Envoy features robust coin control and manual transaction tagging. Through our protocol analysis, external systems can read these user-defined tags and UTXO states. This capability is essential for advanced portfolio management, enabling the categorization of funds for specific business units or risk profiles.

Magic Backups Oversight

Institutional users cannot afford to lose access to funds. We provide an endpoint to monitor the "Magic Backups" synchronization status. By checking if the end-to-end encrypted backup to iCloud or Android Auto-Backup succeeded recently, IT administrators can proactively address disaster recovery risks.

1. Crypto Tax Reporting Automation

Business Context: High-net-worth individuals and corporate entities must maintain precise historical records of their Bitcoin transactions to calculate capital gains accurately.

API & Data Involved: Transaction History, UTXO states, and custom Coin Tags.

OpenFinance Mapping: This solution acts as a read-only OpenBanking bridge for crypto. It extracts historical transaction logs from the local Envoy database and formats them into standard CSV or JSON payloads, which are then automatically ingested by tax calculation software like CoinTracker or Koinly.

2. Enterprise Treasury Dashboard Integration

Business Context: Corporations holding Bitcoin reserves via Passport hardware wallets need real-time financial visibility across all assets without exposing private keys to network risks.

API & Data Involved: Account Balances, Hardware Sync Status.

OpenFinance Mapping: By querying the Envoy companion app's state, our integration pulls cold storage balances into a unified corporate treasury dashboard. This allows CFOs to view Bitcoin reserves alongside traditional fiat bank accounts in real time.

3. Automated Compliance & Security Auditing

Business Context: Institutional custodians must mathematically prove that all deployed wallets are strictly backed up and communicating only over approved, secure networks.

API & Data Involved: Magic Backups Status, Tor/Custom Node Connection Settings.

OpenFinance Mapping: Our scheduled cron-job scripts query the Envoy app environment to verify that end-to-end encrypted backups are current and that the app is routing traffic through the designated corporate Bitcoin node, generating a daily compliance report.

4. Private Payment Verification System

Business Context: E-commerce platforms or merchants accepting Bitcoin directly to their self-custody Envoy wallet require automated confirmation when a customer's payment arrives.

API & Data Involved: Incoming Transactions, Unconfirmed Mempool Data.

OpenFinance Mapping: We deploy a lightweight polling mechanism that monitors the specific Envoy receiving address for new UTXOs. Upon detection, it triggers a secure webhook to the merchant's backend, instantly updating the order status to "Paid".

      "confirmations": 12,
      "tags": ["client_invoice_001"]
    }
    // ... additional transactions
  ]
}

Example: Monitoring Backup Status (Pseudo-code)

// Snippet: Verify Magic Backups health
GET /api/v1/envoy/system/health

Response:
{
  "magic_backups_active": true,
  "last_sync_timestamp": "2025-08-15T08:00:00Z",
  "tor_enabled": true,
  "custom_node_connected": "192.168.1.100:8333",
  "passport_firmware": "v2.2.1"
}

Compliance, Privacy & Security

In the realm of self-custody Bitcoin, security is paramount. Our integration architecture strictly adheres to a read-only OpenData paradigm. We never request, extract, or transmit private keys or seed phrases. All data parsed from the Envoy application is utilized solely for reporting and reconciliation. This approach complies with strict financial data privacy regulations, including GDPR in Europe and the CCPA in California. By leveraging Envoy's native Tor integration and custom node capabilities, we ensure that external integrations do not compromise your network-level privacy or leak metadata to third-party observers.

Data Flow Architecture

Our typical integration architecture involves a secure, localized pipeline designed to minimize attack vectors:

1. Data Extraction: A localized bridge utility safely reads Envoy's unencrypted state data (e.g., transaction caches and tags) on the host device.
2. Ingestion API: The bridge formats this data into standardized JSON and pushes it via encrypted TLS to your internal server.
3. Enterprise Storage: Data is securely logged into your corporate database (e.g., PostgreSQL).
4. Analytics Output: Business intelligence tools (Grafana, Tableau) or tax software consume the data from your database via secure REST APIs.

Market Positioning & User Profile

Envoy is the wallet of choice for privacy-conscious Bitcoin users and enterprises requiring robust self-custody solutions. Its seamless integration with the Passport hardware wallet makes it highly popular among high-net-worth individuals, family offices, and corporate treasuries in North America and Europe. Operating on both iOS and Android platforms, its user base heavily prioritizes open-source transparency, sovereign node verification, and Tor-routed communications over convenience-first custodial alternatives.
