MPCVault has integrated Hinkal into its batch payment workflow. DAOs, funds, market makers, and Web3 enterprises processing $10B+ in weekly transactions through MPCVault can now run treasury operations without publicly exposing payroll structures, vendor relationships, allocation strategies, or internal distribution logic.
‍

How it works in practice:‍

Inside MPCVault’s batch payment dashboard, users can enable confidential transfers via Hinkal. When selected, users:‍

• Connect the same wallet they already use (no new wallet required)
• Choose the payment network (Solana, TRON, Ethereum, and major EVM chains)
• Enter the recipient address (same- or cross-chain)
• Send stablecoins, ETH, or SOL
  ‍

Both sender and recipient remain private. No exposure of balances, revenues, and payment history to counterparties or competitors.
‍

Two optional controls are available:

‍Add Recipient
‍Include multiple recipients within a single transfer flow.

‍Schedule Transfer
‍Define a time window for execution at a randomized moment, reducing time-based analysis.
‍

‍What Appears On-Chain:

• A transfer from the originating address into the Hinkal pool 
• Outgoing transfers from the pool to recipient addresses
  ‍

This removes the direct public link between the treasury and its recipients.
‍

What Happens Under the Hood‍

When a transfer routes through Hinkal, the blockchain verifies it’s valid - but it doesn’t expose internal payment relationships publicly.

Instead of publishing visible sender and recipient links, Hinkal validates the transaction using zero-knowledge proofs. This confirms:

‍

• The sender controls the funds
• The outgoing amount matches the authorized transfer
• No funds are created or double-spent
  
  
  

As a result:

• Recipients receive standard stablecoins or ETH.
• The transaction settles normally on-chain.
• Internal fund distribution is not publicly visible.
  ‍

Compliance and Risk Controls‍

Transactions routed through Hinkal remain subject to compliance monitoring. Hinkal integrates Chainalysis KYT (Know Your Transaction). Transfers are screened using KYT risk assessment tools to support institutional compliance and risk management requirements.

Hinkal also supports selective disclosure via viewing keys. Authorized parties - such as internal compliance teams or auditors - can access transaction details when required. Institutions reduce public exposure while maintaining audit access and ongoing risk oversight aligned with institutional standards.

With Hinkal integrated into MPCVault, confidential treasury payments are embedded directly into institutional operations on public blockchains. Organizations preserve verifiable settlement while removing direct public visibility of internal payment flows - without introducing new wallets, custody changes, or workflow redesign.
