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.

Hyperbridge Protocol
Hyperbridge is a secure system that allows different blockchains to communicate with each other. This communication facilitates the transfer of assets on the blockchain. Unlike older methods that relied on groups of people (multisig committees) to approve transactions, Hyperbridge uses a more robust approach. It leverages the collective agreement of the entire network (consensus) and verifiable proofs (state proofs) to ensure that all communication is fully secure, just as if it were happening on a single blockchain. This decentralized method removes the main point of weakness that has led to billions of dollars in losses in the past. Hyperbridge is the first of its kind in the world.
