Hinkal Bug Bounty
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.

Zynk Protocol
Zynk is a just-in-time liquidity and settlement infrastructure layer for cross-border payment companies. Payment companies often need to pre-fund transactions to provide fast settlements — this ties up capital, slows growth, and makes treasury operations unnecessarily complex. Zynk removes that bottleneck by providing liquidity on a transaction-by-transaction basis, allowing companies to settle faster without locking up idle capital.
