Hyperbridge Launches $50K Bug Bounty Amid Security Review

Hyperbridge, a system enabling blockchains to communicate and transfer assets, has launched a public bug bounty program. The initiative offers rewards of up to $50,000 for critical vulnerabilities in its cross-chain messaging system.

The program follows an April exploit that exposed proof verification risks across Hyperbridge systems. In the incident, an attacker minted approximately 1 billion fake DOT-equivalent tokens on Ethereum through Hyperbridge's cross-chain gateway. The attack gained admin control through a forged cross-chain message and extracted around $237,000 in ether.

The bug bounty program invites independent security researchers to review the protocol codebase and submit reports through the HackenProof platform. Researchers can report logic flaws, access-control issues, reentrancy, cross-chain message spoofing, state manipulation, and any flaw that could affect message or fund integrity.

Rewards start at $200 for low-severity reports and rise to $2,000–$5,000 for medium findings. High-severity bugs can earn $5,000–$15,000, while critical vulnerabilities can receive up to $50,000. The scope covers the full Hyperbridge protocol repository.
