The Vault and Hinkal Bring Confidential Transactions to Institutional Custody
The partnership, announced at a joint networking event in Limassol, integrates Hinkal’s on-chain privacy layer directly into The Vault’s institutional custody platform.
The Vault and Hinkal announced a strategic integration that brings native transaction privacy to institutional digital asset custody. The announcement was made at a joint networking event co-hosted by the two companies in Limassol, Cyprus.
On public blockchains, every balance and every transfer is visible by default. For treasury teams, market makers, and custody clients, this creates a material operational risk: exposed positions, counterparties relationships, and transaction flows susceptible to front-running. The Vault and Hinkal are addressing this directly.
Through the integration, The Vault is embedding Hinkal’s privacy infrastructure (a smart contract on public chains that enables businesses to hold confidential balances controlled through their existing wallet keys) directly into its custody platform. Clients will be able to deposit, send, and withdraw stablecoins with complete privacy, without leaving the custody environment they already use.
The integration delivers two core capabilities:
- Confidential Wallets: deposit, send, and withdraw stablecoins with complete privacy inside the custody surface clients already use.
- Private Settlement: send and receive with counterparties without broadcasting transaction amounts to the public ledger.

Privacy is not a feature you bolt on. It’s infrastructure. Our clients operate at a scale where on-chain transparency is a competitive liability. Integrating Hinkal’s privacy layer means The Vault can now offer confidential transactions as a native product capability, not a workaround.
Our goal has always been to make on-chain privacy feel native to the products institutions already use. Hinkal now powers confidential stablecoin transactions inside The Vault’s custody platform, allowing clients to access privacy without changing their existing workflows and compliance controls. That is what turns privacy from a separate tool into a native institutional functionality.
The Vault serves institutional clients across six segments, including corporate treasuries, financial institutions, professional asset managers, family offices, and payment providers. The Hinkal integration is part of the platform’s broader product roadmap to deliver institutional-grade privacy, compliance, and custody under a single regulated framework.
