HanChain & PayKhan is a dual-token DeFi platform designed to bridge blockchain with real-world commerce and entertainment. Its dual-structure model consists of HAN, a collateral token, and PKN, a stablecoin issued through HAN staking, to ensure transactional stability. Integrated with the PayKhan Wallet, HAN enables online and offline payments, including access to K-pop streaming and content from KHAN’s entertainment ecosystem. PKN powers electronic financial services via PayKhan Cash, bringing blockchain utility to everyday consumer experiences.
Program Overview Hanchain operates a bug bounty program to ensure the continued security and resilience of its decentralized infrastructure. This program invites ethical hackers and security researchers to responsibly disclose vulnerabilities that could impact the platform’s smart contracts or user-facing systems, contributing to the long-term safety and trust of the Hanchain ecosystem.
Reward Structure All submissions are evaluated using a 4-tier severity model, with reward amounts based on the criticality of the vulnerability and the type of asset impacted. Higher-severity vulnerabilities, especially those with real financial or operational risk, are prioritized for higher rewards. Final reward amounts are determined by internal review and severity classification.
Submission Requirements To be eligible for a reward, all bug reports must include a functional proof of concept (PoC) and detailed, reproducible steps that demonstrate the impact of the vulnerability on an in-scope asset. Submissions consisting only of written statements or theoretical analysis without working code will not be considered.
Payouts Rewards are denominated in USD and paid out in HAN, Hanchain’s native token. Bounties are issued directly by the Hanchain team upon successful validation and KYC completion.
