What Is Polareum KMS?

Polareum’s Key Management Service (KMS) is a secure, scalable, and API-driven solution designed for the unique demands of blockchain systems. Whether you’re managing a handful of wallets or orchestrating millions of transactions, our KMS keeps your private keys protected while ensuring seamless signing, rotation, and access control.

Why It Matters

In blockchain, your key is your identity. One misplaced or mishandled key can result in irreversible loss. That’s why we built our KMS from the ground up with zero-compromise security and automation in mind.
From individuals needing safe storage to enterprise-grade applications requiring multi-user access and audit trails, Polareum KMS gives you the control and confidence you need.
