Zubra operates node infrastructure for networks on dedicated private hardware. RPC and archive endpoints for applications, and validator operations. Seven years of operational history, your stable infrastructure partner.
Discuss Your Infrastructure →Zubra's origins are in blockchain. We built our server infrastructure specifically to meet the operational requirements of proof-of-stake networks.
This distinction matters: our monitoring, hardware configurations, network topology, and incident response procedures are all designed around blockchain workloads from the ground up.
Seven years of continuous operation across multiple market cycles and network upgrades has produced a validated set of practices: HSM-backed key management, distributed sentinel node topologies, testnet-first deployment, and defined playbooks for every foreseeable failure scenario.
Our clients are protocols, foundations, institutional stakers, and asset managers who require non-custodial infrastructure managed to institutional standards.
High-availability JSON-RPC and WebSocket endpoints on dedicated hardware. No rate limiting, consistent response times, suited for dApp frontends, wallets, and high-frequency query workloads.
Full historical state access across major networks. Purpose-built for indexers, block explorers, analytics pipelines, and applications requiring complete on-chain data from genesis.
Continuous maintenance: client upgrades, chain forks, configuration tuning, and performance optimisation. All upgrades staged on testnet before mainnet execution.
End-to-end deployment: hardware provisioning, network hardening, client installation, key generation, and testnet validation before mainnet. Standardised runbook for every launch.
HSM-backed signing with support for Web3Signer and Horcrux. Non-custodial by design, clients retain full ownership of all validator keys throughout the engagement.
Protocol-specific observability with 24/7 on-call response. MEV-Boost relay integration for Ethereum. Governance participation and on-chain voting on behalf of delegators.
