Hide the Complexity. Put the Wallet Inside the Product.

Wallets via API,
operations behind it.

Our Technical Approach

Twelve layers under
one wallet API.

Wallet Management Layer
Wallet lifecycle management covering wallet creation, deterministic address generation, hierarchical account structures, wallet segmentation, and configurable provisioning.
Multi-Network Infrastructure
Wallet operations across selected EVM and non-EVM networks, including Bitcoin, Ethereum, and Solana integrations according to project scope.
Transaction Processing Engine
Deposit, withdrawal, internal transfer, transaction building, signing, broadcasting, confirmation tracking, retry, and error-handling workflows.
Policy & Workflow Engine
Configurable transaction limits, approved address lists, approval thresholds, user permissions, and operational restrictions.
Node & Listener Infrastructure
Full-node or managed-node connectivity, RPC and WebSocket listeners, mempool monitoring, address activity tracking, deposit detection, and confirmation workflows.
Security & Key Management
HSM-backed signing, configurable multisignature or MPC workflows, TLS encryption, protected credentials, MFA, and least-privilege access controls.
API & Integration Layer
REST and WebSocket APIs, SDK support, webhook notifications, JWT authentication, role-based authorization, and configurable SSO connectivity.
Monitoring & Logging
Prometheus and Grafana metrics, operational alerts, transaction monitoring, system logs, and administrative audit records.
Data & Reporting Layer
Transaction history, wallet activity records, reconciliation logs, balance data, operational analytics, and configurable reporting datasets.
Admin Dashboard
Web-based management of wallets, networks, balances, transactions, approval workflows, user permissions, alerts, and operational configurations.
DevOps & Infrastructure
Docker and Kubernetes deployments, CI/CD pipelines, Terraform-based Infrastructure as Code, AWS services, and configurable deployment environments.
Optional Integrations
Project-specific connections to external transaction screening and wallet risk systems, accounting platforms, SIEM tools, Redis caching, and third-party services.
