Key management designed for staking, protocols, bridges, and other security-critical applications that are simply impossible without advanced Bitcoin and Babylon support.
Advanced Bitcoin transaction signing and self-custodial Babylon staking, secured with policy guardrails and governance controls.
Babylon Bitcoin staking protocol uses CubeSigner’s advanced Bitcoin signing functionality to secure keys underpinning their self-custodial Bitcoin staking protocol. Their keys remain inside secure hardware during signing and are protected by policies and workflows that restrict how and when they can be used. This gives the Babylon Bitcoin staking protocol a strong defense against key compromise and unauthorized activity, even if faced with infrastructure-level attacks.
“We are excited to work with Cubist on making Bitcoin staking safe at the system and operational levels—in particular, on making it possible for honest node operators and Bitcoin holders to stake without worrying about getting slashed due to bugs, mistakes, or network issues.”
Use intuitive APIs that save your sanity and your weekend.
Manage Bitcoin keys with an API that supports key import, key generation, simple transfers, and arbitrary PSBTs for SegWit, Taproot, and Legacy transactions.
Ensure your staking keys can only be used to sign the correct Babylon transactions via policy-protected workflows. Ensure your finality provider doesn't get slashed by using EOTS keys that have built-in anti-slashing policies.
Restrict keys from signing Bitcoin transactions that exceed a maximum value over a time window, or violate other protocol parameters you’ve set.
Ensure only the correct users can withdraw their BTC from your service. CubeSigner locks in withdrawal addresses at deposit time, blocking attackers from redirecting funds later.
Get the security you need, with the flexibility others don’t offer.
