HOW IT WORKS

Three steps to secure custody

From deposit to redemption, every step is verified on-chain with zero-knowledge proofs and real-time IoT auditing.

1
Deposit
Physical gold delivered to OZ Vault or digital assets transferred on-chain. Verified, weighed, and registered on ProbeChain.
2
Verify
ProScan IoT sensors continuously audit physical assets. ZK-Rollup Truth Layer generates cryptographic proof of reserves, verifiable by anyone.
3
Redeem
Redeem OZ tokens for physical gold coins at any time. Sovereign settlement: 1oz gold coins delivered globally, or swap on-chain instantly.
SECURITY

Fortified at every layer

Post-quantum cryptography, multi-signature governance, cold storage architecture, and continuous real-time auditing protect your assets against current and future threats.

🔐
Post-Quantum Cryptography
ProbeChain implements lattice-based cryptographic primitives, ensuring custody records and asset proofs remain secure against quantum computing attacks.
🔑
Multi-Signature Governance
All custody operations require multi-signature approval across independent key holders distributed in separate jurisdictions. No single point of compromise.
🧊
Cold Storage Architecture
Digital asset keys secured in air-gapped, hardware-encrypted cold storage. Physical gold in bank-grade vaults with biometric and multi-factor access controls.
📡
ProScan IoT Audit
Real-time IoT sensors monitor physical vault conditions 24/7. ZK-Rollup Truth Layer generates tamper-proof audit trails, verifiable by any third party on-chain.
🛡
ZK-Rollup Truth Layer
Zero-knowledge proofs verify reserves without exposing sensitive custody details. Cryptographic guarantees that assets exist, without revealing where or how they are stored.
