The Vault is integrating Hinkal to bring confidential stablecoin payments and private settlement directly into its institutional custody platform.
The integration was announced at a joint networking event co-hosted by The Vault and Hinkal in Limassol, Cyprus, and marks an important step in bringing transaction privacy into the custody layer itself.
The Vault is an institutional infrastructure platform for digital assets, supporting clients across secure custody, treasury operations, and structured investments. With Hinkal, The Vault is adding private stablecoin functionality to its environment.
Clients will be able to deposit, send, withdraw, and settle stablecoins privately, without exposing balances, counterparties, or payment amounts on-chain.
The integration brings two core capabilities to The Vault.
Confidential Wallets let clients hold and move stablecoins privately inside The Vault.
Balances and transfers stay confidential on-chain, while control remains with the wallet keys clients already use. The key that controls the public balance also controls the confidential one, so privacy is added without changing the custody model.
Clients can deposit, send, and withdraw stablecoins privately from within the same platform experience.
Private Settlement lets counterparties settle stablecoin payments without publishing the amount to a public ledger.
A transaction that would normally expose the payment amount, timing, and counterparty relationship can instead settle confidentially between the parties involved.
For institutions, that matters. Public blockchains make every transfer visible by default. At scale, that visibility can reveal positions, counterparties, settlement timing, treasury movements, and commercial relationships.
The Vault’s integration with Hinkal brings privacy to those flows without asking clients to leave the custody platform.

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.
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.
The integration is enabled through Hinkal’s SDK, which connects The Vault’s product to Hinkal’s privacy infrastructure.
That means privacy is added at the infrastructure layer, not as a separate application, wallet, or workflow.
There is no privacy system for The Vault to build from scratch. No new custody model to introduce. No separate tool for clients to manage.
Hinkal SDK gives platforms a way to add private stablecoin payments into existing custody, treasury, payout, and settlement products without changing how users operate inside the products.
Institutional privacy is selective disclosure.
The goal is not to hide activity from regulators or auditors. It is to prevent sensitive financial activity from being exposed to the entire market by default.
With Hinkal, transaction activity can remain confidential from competitors, unrelated counterparties, and public observers, while still being disclosable to the parties entitled to see it.
Viewing keys allow clients to grant access to specific activity when required, including to auditors, regulators, or approved counterparties.
For stablecoin settlement to become institutional infrastructure, that distinction matters.
Stablecoins are becoming a core settlement layer for digital asset markets, treasury operations, and institutional payments.
But public settlement creates a problem for institutions.
Every payment leaves behind a visible record. Every wallet balance can be monitored. Every counterparty relationship can be mapped. Every treasury movement can become market intelligence.
Custody platforms are where institutions already manage assets, permissions, approvals, reporting, and compliance. That makes custody the natural place for stablecoin privacy to live.
The Vault’s integration with Hinkal brings confidential payments into that custody environment directly.
Through API and SDK infrastructure, Hinkal brings confidential stablecoin payments into existing custody, treasury, payout, wallet, and settlement products. Privacy is added at the infrastructure layer, while the user experience stays inside the platform clients would usually operate on.
Businesses can hold confidential balances and transact privately across supported networks, while keeping control through existing wallet keys and preserving selective disclosure for compliance.
That means platforms can add privacy without building the cryptography themselves, without changing their custody model, and without forcing users into a new operating flow.
Hinkal has processed over $500M in private volume and supports use cases across wallets, custody platforms, payroll companies, neobanks, exchanges, OTC desks, payment platforms, and merchants.
For institutions, privacy only works if adoption is seamless, integrated into the flows enterprises use.
