Universal Privacy on Public Chains

Hinkal brings universal privacy to stablecoin payments, settlements, and payouts across Ethereum, Solana, TRON, and major EVM networks.

What it is

Hinkal is a smart contract on the public chains you already use. It lets institutions, payment platforms, applications, and individuals hold private balances controlled by their existing wallet keys - and transact from them without exposing balances, counterparties, or treasury activity.

Why it matters

Public blockchains provide global, neutral settlement, but their default transparency creates material risks: revenue leakage, counterparty mapping, balance surveillance, and operational exposure.

How it works

Hinkal embeds privacy directly into on-chain execution rather than relying on private blockchains, mixers, custodial intermediaries, or application-level obfuscation. It plugs into existing wallets, payment stacks, and workflows with no liquidity migration, preserving composability and public-chain finality.

Every on-chain action - across any supported chain, wallet, or use case - keeps sender, recipient, and amount private. Users retain full control of their assets; transactions execute through private routing and shielded settlement, removing public attribution.

Compliant by design

Privacy is enforced by default. Compliance and auditability are preserved through Chainalysis KYT screening at entry and, when required, selective disclosure via viewing keys and downloadable transaction history.

Hinkal makes privacy the prerequisite for stablecoin payments to scale into institutional and everyday use.
