Narval provides a policy-based connectivity and orchestration layer that enables applications to seamlessly integrate with any institutional custodian. Our platform combines enterprise-grade security with developer-friendly APIs to solve the challenges of multi-custody integration and management.
Our infrastructure leverages both MPC and TEE technologies to ensure the highest level of security for sensitive API credentials via flexible policy controls. Through a single unified API, applications can implement sophisticated authorization policies and quickly integrate with major institutional custodians without managing multiple complex integrations or handling sensitive credentials directly.
The platform features policy-based access control, secure credential management through AWS Nitro Enclaves, MPC-based authorization decisions, and end-to-end request integrity verification. We support comprehensive custody operations including transfer initiation, and approval workflows across multiple custodians.
Developers can deploy Narval either through our managed cloud service running entirely in secure enclaves or self-host it in their preferred environment - saving months of integration time. Our open-core approach ensures transparency while providing enterprise features for institutional requirements.
Choose Narval as your trusted partner to accelerate custodian integration, enhance security controls, and simplify custody operations across your application stack. Our platform is backed by leading US and European VCs and is trusted by institutional clients globally.
