Institutional Custody Gets Private Stablecoin Transfers
The Vault integrates Hinkal's zero-knowledge privacy protocol for stablecoin custody, removing public-ledger transparency as a barrier for corporate payments and payroll.

The Vault, an institutional custody platform, has integrated Hinkal's privacy protocol to let clients move stablecoins without broadcasting transaction data on public blockchains. The partnership targets a friction that has kept many corporate treasuries and payment firms from running large sums through crypto rails.
Public ledgers record every transfer – wallet addresses, amounts, timestamps – visible to anyone running a node. For institutions handling payroll, supplier payments, or intercompany transfers, that level of transparency clashed with commercial confidentiality. A rival could see exactly when a company pays its vendors and at what scale.
Hinkal uses zero-knowledge proofs to cloak transaction details while still proving the transfer follows the blockchain's rules. The technology wraps a standard send into a privacy pool so only sender and recipient see the specifics. Regulators and auditors get controlled disclosure, not full transparency.
The Vault is not a trading venue. It offers custody for tokenized securities, stablecoins, and digital assets aimed at institutions. By embedding privacy at the custody layer, it removes the need for clients to manage their own privacy setups or shuttle funds to a separate platform for confidential transactions.
