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:

// Precompiled contract at 0x0000000000000000000000000000000000000801
interface IShieldedPool {
    /// @dev Payable — the deposited amount travels in msg.value, not in an argument.
    function shield(
        uint32 assetId,
        bytes32 commitment,
        bytes calldata encryptedMemo
    ) external payable;

    function unshield(
        bytes calldata proof,
        bytes32 root,
        bytes32 nullifier,
        uint32 assetId,
        uint256 amount,
        bytes32 recipient,
        uint256 fee,
        bytes32 changeCommitment,
        bytes calldata changeEncryptedMemo,
        uint32 circuitVersion
    ) external;
}

Withdrawing carries the proof and every public signal it commits to, so the signature is long by design. The full interface also covers private transfers and the relayer calls.

Building a payment flow

Your dapp reads the chain and composes the payment; an Orbinum wallet holds the keys and performs the spend. You never handle a spending key.

import {
  OrbinumClient,
  sealPaymentSlip,
  encodePaymentSlip,
} from '@orbinum/protocol';

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

// Seal a slip toward the recipient's viewing public key, then hand it to a wallet.
const envelope = sealPaymentSlip(recipientIvkPacked, {
  commitmentHex,
  encryptedMemo,
});

const wire = encodePaymentSlip(envelope); // 'orbslip1:…'

See Building on Orbinum for the public client, payment slips, and address helpers, and the wallet SDK for the custody side of the boundary.
