Ethereum Validator Infrastructure & Managed Staking

Attestant provides institutional-grade Ethereum validator infrastructure through managed staking services and enterprise validator technology. Their flagship service enables institutional clients to stake ETH using non-custodial architecture where Attestant manages signing keys for validator operations while clients retain exclusive control of withdrawal keys, ensuring funds remain secure and accessible only to the client.

Managed Staking Services

Attestant operates validators on behalf of institutional investors, family offices, foundations, and asset managers. Their infrastructure features multi-node architecture using the proprietary Vouch validator client, distributed key management via Dirk, geographic redundancy across multiple data centers, and ISO 27001 certified security systems. Clients benefit from enterprise-grade reliability, maximum validator uptime, transparent blockchain-visible performance tracking, and comprehensive monitoring while Attestant handles all technical complexity.

B2B Infrastructure Partnerships

For custodians, exchanges, and financial institutions, Attestant offers white-label validator infrastructure partnerships. Rather than building staking systems from scratch, partners leverage Attestant's battle-tested technology and operational expertise to launch staking services in weeks. This includes 24/7 validator management, protocol upgrade handling, multi-client architecture for network resilience, performance analytics, and compliance frameworks. Partners maintain customer relationships and custody while Attestant provides the technical backbone.

Proprietary Validator Technology

Vouch Multi-Node Validator Client is Attestant's open-source validator client designed for production environments. Unlike single-node clients, Vouch connects to multiple beacon node implementations simultaneously (Lighthouse, Prysm, Teku, Nimbus), making validation decisions based on consensus across data sources. This architecture dramatically improves reliability, protects against client implementation bugs, and enables safe client diversity support. Features include slashing protection, extensive monitoring with Prometheus metrics integration, graceful degradation capabilities, and production-ready design for managing thousands of validators efficiently.

Dirk Distributed Remote Key Manager provides enterprise-grade security for validator signing keys using threshold cryptography. Keys are split into shares distributed across multiple independent servers, requiring a threshold of shares (e.g., 2-of-3 or 3-of-5) for signing operations. This ensures no single server compromise exposes keys while maintaining high availability. Dirk implements wallet encryption, TLS mutual authentication, built-in slashing protection, granular access controls, and comprehensive audit logging. The remote signing architecture allows keys to reside in highly secure environments while validator operations run in separate infrastructure.

Infrastructure Highlights

• Non-custodial security: Clients always control withdrawal keys and funds
• Client diversity: Multi-client support reduces systemic risk
• High availability: Geographic redundancy and fault-tolerant architecture
• Enterprise compliance: ISO 27001 certification and institutional frameworks
• Proven track record: Operating validators since before Ethereum 2.0 beacon chain launch (December 2020)
• Open source contribution: Vouch and Dirk publicly available on GitHub for community review
• Scalability: Infrastructure supports thousands of validators efficiently
• MEV awareness: Advanced monitoring and optimization capabilities

Target Clients

Institutional investors, investment firms, asset managers, family offices, foundations, endowments, cryptocurrency custodians, exchanges, digital asset platforms, wealth management firms, and treasury departments managing digital assets. In the UK, services are directed to investment professionals, high net worth entities, and sophisticated investors as defined under the Financial Services and Markets Act 2000.

Service Integration

Attestant's infrastructure combines Vouch and Dirk to create a highly secure, available staking platform. Vouch handles multi-node validator logic and duty scheduling while Dirk manages keys and provides distributed signing services. Both scale independently based on operational needs, allowing institutional operators to secure keys in locked-down environments while running validator logic in accessible infrastructure. Integration options include white-label deployments, co-branded solutions, API integrations, and custom reporting tailored to partner requirements.
