Secured Digital Assets

100%

Audit Trail Coverage

Single Points of Failure

The Enterprise Digital Asset Challenge

Traditional blockchain security fails enterprises because development teams and end users work in isolated systems without unified control.

👥

Team Isolation

Developers build secure smart contracts, but teams cannot collaborate on asset management.

🏢

CFO Control

CFOs need enterprise controls, but developers work with individual wallet addresses.

📊

Compliance Gaps

Compliance requires audit trails, but blockchain transactions are scattered across multiple systems.

🔐

Single Points of Failure

Crypto wallets are isolated single-user tools without team collaboration capabilities.

Three-Address Protocol Security

Revolutionary security architecture that provides multiple independent layers for complete asset protection.

Defense-in-Depth Architecture

Owner Address (EOA)

Primary wallet control - first layer of security with direct asset ownership.

ChainGuard 2FA Signer

Off-chain mobile 2FA with on-chain validation - airgapped security layer.

Guardian Attestation (Optional)

Server-side enterprise oversight for high-value operations and compliance.
