Hinkal

Hinkal provides privacy infrastructure for stablecoin payments and on-chain financial operations, enabling users and businesses to transact without publicly exposing sensitive financial information such as balances, transaction amounts, and counterparties. The protocol uses zero-knowledge proofs to preserve transaction privacy while maintaining verifiable on-chain execution. This bounty program covers the core protocol smart contracts and the zero-knowledge circuits that gate fund movement. We are looking for critical vulnerabilities that could result in loss of user funds, unauthorized minting/withdrawal of shielded balances, bypass of proof verification, or breaks in the privacy guarantees the protocol is designed to provide.
