About Royen Core

Royen Core is a cross-platform desktop application designed for professional Bitcoin Core node operators managing portfolios from 1 BTC up to 5 k BTC+. It connects directly to your local Bitcoin Core full node, performing on-chain validation and relay without trusting any third party. By interfacing via RPC (“getbalance,” “listunspent,” “sendmany,” etc.), it provides seamless control over on-chain operations from a modern GUI

Under the hood, the backend is built on Node.js, leveraging its event-driven, non-blocking I/O architecture to handle thousands of simultaneous RPC requests and HSM interactions efficiently. The frontend runs on Electron, embedding Chromium and Node.js to deliver a familiar desktop experience across Windows, macOS, and Linux without platform-specific codebases

Security & Key Management

NodeVault Pro embeds PKCS#11–compliant HSM integration, ensuring all private keys are generated, stored, and used within tamper-resistant hardware modules. Multi-party workflows use Bitcoin’s PSBT format combined with “createmultisig” RPC calls to enforce m-of-n signature policies, enabling robust multisig vaults for corporate treasuries. Air-gapped signing protocols allow transaction approval on an offline device, minimizing remote-attack surfaces.

Compliance & Audit Reporting

Built-in Chainalysis KYT integration continuously screens incoming and outgoing transactions, assigning risk scores and flagging suspicious flows in real time. SOC 2®–standard audit reports are auto-generated for all RPC calls and transactions, covering security, availability, confidentiality, and processing integrity criteria. Custom KYC/AML dossiers can be exported for regulators or internal review with a single click.

Analytics & Visualization

Operational dashboards powered by Recharts deliver live portfolio analytics—P&L tracking, on-chain UTXO management, and risk indicators—directly in your desktop app. Drill down into individual addresses, monitor Value at Risk (VaR) and Sharpe ratios across your multi-address holdings, and receive signal alerts when thresholds are crossed.

Data Storage & Reliability

PostgreSQL underpins all metrics, UTXO indexing, and audit log storage, offering ACID guarantees and extensible SQL compliance for advanced querying. Incremental database snapshots and automated backups ensure rapid recovery and minimal data loss in disaster scenarios.

Deployment & DevOps

NodeVault Pro ships as Docker containers for both the app and its HSM mock-server (for development/testing), enabling consistent environments from local machines to cloud VMs. GitLab CI/CD pipelines automate linting, unit and integration tests, container builds, and staged deployments—ensuring zero-downtime updates and production-grade reliability
