Hyperbridge has launched a public bug bounty program following a recent bridge exploit that exposed weaknesses in its cross-chain verification system. The program is now live on HackenProof and offers rewards of up to $50,000 for critical security vulnerabilities.<\/p>\n\n\n\n
The initiative invites independent security researchers to review Hyperbridge\u2019s protocol codebase and report vulnerabilities that could impact message validation, asset transfers, or fund safety.<\/p>\n\n\n\n
According to the HackenProof listing, Hyperbridge is designed to help blockchains communicate and transfer assets using consensus and state proofs instead of traditional bridge systems that rely on multisig validator committees.<\/p>\n\n\n\n
The reward structure depends on the severity of the issue discovered. Low-severity findings can earn around $200, while medium-level vulnerabilities may receive between $2,000 and $5,000. High-severity bugs qualify for rewards ranging from $5,000 to $15,000, while critical vulnerabilities can receive payouts of up to $50,000.<\/p>\n\n\n\n
The program covers the full Hyperbridge protocol repository. Researchers are encouraged to identify issues such as logic flaws, access-control weaknesses, reentrancy vulnerabilities, cross-chain message spoofing, and state manipulation attacks.<\/p>\n\n\n\n
The bug bounty launch comes shortly after a major exploit in April. During that incident, an attacker reportedly minted nearly 1 billion fake DOT-equivalent tokens on Ethereum through Hyperbridge\u2019s cross-chain gateway.<\/p>\n\n\n\n
Investigators said the attacker gained administrative control through a forged cross-chain message and later extracted roughly $237,000 worth of Ether. Although the exploit affected the bridged representation of DOT, Polkadot\u2019s native network itself was not compromised.<\/p>\n\n\n\n
The incident highlighted a broader problem facing cross-chain bridge infrastructure. Weak proof verification and forged message attacks continue to be among the most common vulnerabilities in blockchain bridge systems.<\/p>\n\n\n\n
Hyperbridge also outlined strict testing rules for participants. Researchers must conduct testing only on local forks, while attacks against live infrastructure, social engineering attempts, third-party exploits, spam, and denial-of-service testing remain prohibited.<\/p>\n\n\n\n
The platform additionally requires proof-of-concept submissions for reported vulnerabilities and prohibits public disclosure without approval from the team.<\/p>\n\n\n\n
Bridge security remains a major issue as blockchain interoperability expands. Hyperbridge previously appeared in crypto industry discussions after Enjin Blockchain used the protocol on testnet in 2025 for cross-chain stablecoin transfers involving USDC and USDT between Ethereum and BNB Chain.<\/p>\n\n\n\n
As cross-chain activity grows, the new bug bounty program represents Hyperbridge\u2019s latest effort to strengthen protocol security and reduce the risk of future exploits.<\/p>\n\n\n\n
