Vinu Digital develops configurable digital asset wallet infrastructure for secure asset management, transaction workflows, treasury operations, and blockchain network integrations.
Direct control over
keys and approvals.
Deterministic Wallet ArchitectureGenerate and manage large numbers of wallet addresses through configurable addressing and deployment models designed for institutional asset operations.
HSM, Multisig & MPC Key ManagementConfigure HSM-backed signing, multi-signature policies, and MPC-based workflows according to security, governance, and operational requirements.
Hot, Warm & Cold Wallet OperationsSeparate transactional, operational, and reserve assets through wallet tiers with distinct access, approval, and transfer policies.
Policy-Based Transaction ApprovalsApply approval thresholds, role assignments, transaction limits, cooling-off periods, and separation-of-duty controls.
Automated Sweep & Treasury WorkflowsAutomate asset consolidation, batch transfers, gas handling, balance monitoring, retries, and treasury movements.
Multi-Network Asset SupportManage digital assets across selected EVM and non-EVM blockchain networks through modular network adapters.
Institutional Admin ConsoleControl networks, wallets, balances, transactions, approvals, listeners, users, and operational policies through one interface.
Ten technical layers,
one custody stack.
- On-Chain Smart Contract Layer
- Solidity-based contracts, CREATE2 deterministic addressing, ERC-1167 minimal proxy patterns, EIP-1559 transaction support, Safe multisig treasury workflows, and OpenZeppelin security modules including ReentrancyGuard and AccessControl.
- Node & Listener Infrastructure
- Ethereum and selected EVM full or archive nodes, WebSocket and RPC event listeners, mempool and nonce monitoring, gas oracle integration, and configurable gas optimization logic.
- Workflow & Orchestration
- Kubernetes CronJobs, containerized worker microservices, Kafka or RabbitMQ event queues, automated retries, and reorganization-aware transaction handling.
- API & Integration Layer
- REST and WebSocket APIs, webhook notifications, JWT authentication, role-based authorization, and configurable SSO through OIDC or SAML.
- Monitoring & Logging
- Prometheus and Grafana metrics, optional OpenTelemetry support, detailed audit trails, and configurable Slack, Discord, or PagerDuty alerts.
- Security & Key Management
- HSM-backed signing through CloudHSM or YubiHSM, configurable multisig policies, TLS-encrypted connections, KMS-based encryption at rest, MFA, and least-privilege access controls.
- Data & Reporting Layer
- PostgreSQL, BigQuery-based OLAP reporting, reconciliation records, transaction history, AML/KYC audit datasets, and reporting capabilities designed to support compliance processes.
- Admin Dashboard
- Web-based management of blockchain networks, assets, balances, transaction history, chain analysis, listeners, schedulers, monitoring, and manual or automated sweep operations.
- DevOps & CI/CD
- GitHub Actions and GitLab CI pipelines, Docker and Kubernetes deployments, Terraform Infrastructure as Code, Cloudflare, and AWS-based infrastructure services.
- Optional Integrations
- Project-specific KYT/AML services, Layer 2 and bridge connectivity, SIEM integrations including ELK, Loki, and CloudWatch, and Redis-based caching where required.

Four controlled steps
to production launch.
Define supported assets, blockchain networks, wallet tiers, key management models, approval policies, user roles, and reporting requirements.
Your institution,
your rules, your keys.
Institution-Specific Security Models
Configure HSM-backed signing, MPC, multi-signature policies, approval thresholds, and access controls around internal governance requirements.
Direct Operational Control
Maintain control over wallet policies, signing workflows, treasury movements, user permissions, and transaction execution within the institution’s infrastructure.
Modular Custody Architecture
Deploy the custody engine, network adapters, monitoring, reporting, key management, and integration components required for each project.
Automated Asset Operations
Coordinate transaction validation, asset sweeps, batch processing, fee management, retries, and treasury workflows through configurable automation.
Multi-Network Capability
Manage supported EVM and non-EVM blockchain networks through modular node, listener, wallet, and asset-management layers.
Banking and Exchange Integrations
Connect custody infrastructure with exchange platforms, banking systems, payment services, internal applications, and external screening tools through APIs and webhooks.
Auditability and Operational Visibility
Track approvals, transfers, sweeps, access events, configuration changes, and reconciliation records through centralized monitoring and audit trails.
End-to-End Technical Delivery
Cover architecture design, security configuration, integration, testing, deployment, documentation, training, and agreed technical support within one delivery scope.
Your environment,
your delivery terms.
- 01
Deployment Model
Deploy the custody infrastructure in a dedicated environment aligned with the institution’s security policies, network architecture, operational controls, and hosting requirements.
- 02
Delivery & Service Model
Choose an end-to-end implementation, joint delivery with internal teams, or ongoing technical support covering integration, testing, documentation, training, and operational continuity.
- 03
Commercial Model
Define the commercial scope according to required custody modules, supported networks, integrations, implementation services, and ongoing support requirements.
