Manage validator keys with policy-driven workflows, built-in anti-slashing, and secure hardware protection at rest and during signing. Available for Ethereum, Babylon, Avalanche, and Cosmos staking.
Safe staking requires more than just slashing protection—it demands reliable automation, strict access controls, and resilient infrastructure. Unlike traditional remote signers, CubeSigner keeps validator keys locked inside secure hardware even during signing, never exposing them (to attackers!) in memory. Policy-protected key management workflows safeguard staked funds from deposit to withdrawal, defending against compromise even in the face of software vulnerabilities or system failures.
Lock down validators with technology, not playbooks.
Ankr enlisted Cubist to secure staked funds against insider threats and validator compromises. Using CubeSigner, they locked down Ethereum staking, validator signing, and withdrawals—ensuring capital is secure before staking, transactions can’t be altered by attackers, validators can’t sign slashable messages, and withdrawals can’t be redirected to malicious addresses. Even if an attacker breaches Ankr’s system, staked funds will stay within their protocol.
“Cubist’s professionalism and attention to detail at every turn place them among the best of companies that we’ve worked with. They are uniquely qualified to secure Ankr’s most critical workflows. We believe Cubist’s involvement makes Ankr one of the most secure choices for Ethereum staking.”
Simplify operations, save infrastructure costs, and close security gaps with policy-driven automation.
