# Whitepaper (Preface)

**Hinkal brings universal privacy to stablecoin payments, settlements, and payouts across Ethereum, Solana, TRON, and major EVM** [**networks**](/hinkal/ecosystem/supported-chains.md)**.**

**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.**
