Hinkal
Hinkal
Hinkal is a non-custodial on-chain privacy protocol that enables confidential transactions on public blockchains through shielded addresses, zkSNARKs and a shielded pool, with relayers using trusted execution environments. It obscures sender, recipient and amounts while keeping settlement verifiable on networks like Ethereum, Solana, Tron and Polygon, and requires KYC(B) attestations for access as a compliant answer to the Tornado Cash model. It offers a confidential-payments SDK for wallets, exchanges and institutions and is a B2B solution, not an end-user product.

FAQ
Does Hinkal custody user funds?
No. It is a non-custodial protocol: assets remain under the user's control through the shielded pool and zero-knowledge proofs.
Is Hinkal anonymous like traditional mixers?
No. Hinkal requires KYC(B) attestations for access, positioning itself as a compliant alternative to mixers rather than a full-anonymity tool.
