Key management choices determine what protocols can guarantee.

Rethink key management as protocol logic: It defines who holds power, how change happens, and what’s protected over time. What a protocol can do depends on what its keys can do.

Challenges

Key management isn’t just infrastructure—it’s protocol design.

How you manage your keys shapes who controls your protocol, how securely your logic executes, and whether your chain can keep up under pressure. CubeSigner makes key management a first-class part of protocol architecture—where policies enforce decentralized governance and high-performance signing delivers consistent uptime.

Solutions

This is how design meets execution.

Turn protocol rules into system behavior.

Out-of-the-box consortium signing

Easily deploy a trust-minimized key setup where no single party (or validator) controls the protocol, with built-in support for multi-party governance and timelocks to minimize counterparty risk.

Policy-protected workflows

Lock down core workflows like deposits, withdrawals, and anti-slashing with TEE-backed execution using hardware-enshrined smart contracts.

High-performance signing

Keep your protocol fast, responsive, and resilient. CubeSigner makes sure transaction signing is never the bottleneck—because if your validators can't sign (on time), your chain's liveness is at risk.

A Case Study on Protocols & Governance

Quorum Signing: A Real-World Use Case

Yala Protocol solves Bitcoin's smart contract limitations by implementing a bridge powered by CubeSigner, ensuring deposited Bitcoin can only be used as designated collateral or returned to its rightful depositor. This architecture—enabled by Hardware-enshrined Smart Contracts—brings DeFi functionality to Yala's Bitcoin-based lending protocol through distributed key management backed by hardware security, access control policies, and decentralized control.

Case Study

"Our implementation of CubeSigner for the Bitcoin bridge represents the critical security foundation of the entire Yala Protocol ecosystem. By securing this entry point with hardware-level protections, we've created a trustless environment where Bitcoin holders can confidently participate in DeFi without sacrificing the security guarantees they expect."

Vicky Fu • Co-Founder & CTO of Yala

Benefits

Make sure your protocol stands up to the real world.

Treat key management as your control layer for change, risk, and growth.

Protect core operations

Enforce non-custodial control and decentralized governance by locking down key usage, protocol operations, and upgrades with multi-party approvals and custom policy logic, on any chain.

Prevent unauthorized upgrades

Ensure that only the correct code reaches your production system by securing upgrade keys with policies (e.g., requiring smart contract code to be signed by your CI pipeline).

Extend seamlessly

Build multi-chain applications and effectively extend the functionality of existing protocols—without the complexity of protocol upgrades (e.g., add support for smart contracts to Bitcoin, delegate staking to Ethereum, etc.).

Make governance part of your architecture.
