Unbound’s Digital Asset and Blockchain
Security Platform

The only FIPS 140 L2 certified Multi-Party-computation (MPC) security platform for digital assets.

Secure Like It’s Cold. Transact Like It’s Hot. With Unbound’s Crypto Asset
Security Platform (CASP) you can define multi-party risk-based approval policies that
adhere to local regulations, can integrate HSMs and offline signers into one
MPC based platform.

The Institutional
Standard for Digital
Asset Security

A FIPS 140 L2 certified software solution that eliminates this single point of failure of public-key cryptography by giving you a secure, distributed way to sign transactions while managing all your digital assets. With Unbound CASP, institutional investors don’t have to choose between regulatory adherence, peace of mind, and asset productivity.

How can CASP help?

Connected and Disconnected Wallets in One Platform
One comprehensive system that safeguards digital assets in both ‘cold’ and ‘hot’ vaults, while using MPC-based workflows and approval policies to secure the transfers between the two types of vaults.
Cryptographically Validated, Risk Based Policies
CASP supports any approval-policy structuring and any (unlimited) number of cryptographically validated signers . That’s true multi-party computation.
Validated by Enterprise Grade, Risk Averse Customers
Deployed by enterprise grade, risk averse institutions, that are taking CASP through extensive vulnerabilities testing and periodic pen testing.

Key Features

CASP Deployment


• Keys exist as shares – no single point of failure
• Key material is never exposed
• Enforce multi-party quorum approval for transactions
• Breach = compromising multiple parties simultaneously

• Keys exist as shares – no single point of failure
• Hot, warm and cold vaults in one environment
• HSM as an integral part of the architecture
Cold signers as part of the architecture.

• Keys exist as shares – no single point of failure
• Key material is never exposed
• Each vault can have different ‘Risk Based Policies’
• Each policy can have multiple signers and will be activated according to the risk level.
• Risk level is set by the combination of the asset type, the amount, the day in the week and the time of day.
