Universal Privacy on Public Chains

What is Hinkal

Hinkal is a universal confidential settlement and transaction infrastructure for public blockchains, built for Ethereum, Solana, and major EVM networks. It enables institutions, payment platforms, and applications to operate on public chains without exposing balances, transaction history, counterparties, or settlement flows.

Public blockchains provide global, neutral settlement — but their default transparency creates material risks for enterprises: revenue leakage, counterparty mapping, balance surveillance, and operational exposure. Hinkal addresses this by delivering universal protocol-level confidentiality on existing public rails, without requiring private blockchains, custodial intermediaries, or liquidity migration.

Unlike privacy-specific chains, mixers, or application-level obfuscation, Hinkal is designed as neutral, universal middleware that plugs into existing wallets, payment stacks, and institutional workflows while preserving public-chain finality and composability.

Hinkal operates as a non-custodial system. Users retain full control over their assets while executing transactions through confidential routing and shielded settlement mechanisms that remove public attribution.
