Institutional Finance

Private Treasury Management

Organizations can manage treasury operations without exposing holdings:

Benefits:

• Hide treasury size from competitors
• Prevent front-running on large transactions
• Maintain audit trail via view keys

Confidential Payroll

Process salary payments without revealing individual compensation:

Traditional	With Orbinum
All salaries visible on-chain	Only total payroll amount visible
Employee addresses linked to amounts	Employees receive via private notes
Easy to analyze compensation structure	Privacy preserved, audit possible

---

Enterprise Operations

B2B Settlements

Execute inter-company payments without revealing business relationships:

• Shield incoming payments from customers
• Transfer internally between departments
• Unshield for vendor payments
• Full audit trail available to authorized parties

Supply Chain Privacy

Track goods through supply chain while protecting commercial relationships:

• Suppliers shield product commitments
• Transfers between intermediaries remain private
• End recipient verifies provenance via ZK proof

---

Individual Privacy

Personal Asset Management

Individuals can manage digital assets with bank-grade privacy:

• Shield tokens to hide balance from public view
• Transfer between personal accounts privately
• Unshield only when needed for public transactions

Compliance-Ready Privacy

Unlike fully anonymous systems, Orbinum supports regulatory compliance:

User generates View Key → Shares with auditor → Auditor verifies transactions
                                              → User privacy preserved from public

Technical Integration

EVM Compatibility

Deploy standard Solidity contracts that interact with the shielded pool:

// Interact with Orbinum privacy features from Solidity
interface IShieldedPool {
    function shield(uint256 amount, bytes32 commitment) external;
    function unshield(bytes calldata proof, bytes32 nullifier) external;
}

SDK Integration

Use the Orbinum SDK for privacy operations:

import { OrbinumClient, NoteBuilder, generateTransferProof } from '@orbinum/sdk';

// Connect
const client = await OrbinumClient.connect({
  substrateWs: 'wss://rpc-1.testnet.orbinum.io',
});

// Build a note locally (commitment + nullifier + encrypted memo)
const note = await NoteBuilder.build({
  value: 100n,
  assetId: 0n,
  ownerPk,
  blinding,
  spendingKey,
});

// Generate the ZK proof for a private transfer
const proof = await generateTransferProof(/* inputs, merkle proofs, outputs */);

See SDK & Developer Tools for the full client, note, and vault surface.
