ENTERPRISE-GRADE SECURITY
Our Key Management & Security Capabilities
Secure your validator infrastructure with institutional-grade key management, multi-layered security protocols, and 24/7 monitoring designed for high-value staking operations.
01
Hardware Security Module (HSM) Integration
Private keys are generated, stored, and signed within FIPS 140-2 Level 3 certified HSMs. Keys never leave the secure hardware boundary, eliminating single points of failure and protecting against remote extraction.

02
Multi-Party Computation (MPC) & Threshold Signing
Implement distributed key generation and signing using MPC protocols. Eliminate single points of compromise by requiring a threshold of signatures from geographically separated nodes for any validator action.

Expert Answers for Technical Leaders
Validator Key Security: Frequently Asked Questions
Get clear, technical answers to the most common questions CTOs and founders ask about securing validator keys and managing staking infrastructure.
We implement a defense-in-depth strategy combining air-gapped key generation, multi-party computation (MPC) for signing, and hardware security modules (HSMs). Our process is based on the NIST Cybersecurity Framework and tailored for Proof-of-Stake consensus. We never store a single, complete private key in one location, eliminating single points of failure. All key ceremonies are conducted using audited, open-source tooling like ethdo and staking-deposit-cli in secure, isolated environments.
