Blockchain security firm CertiK has received a generous $500,000 bounty from Sui, marking a significant milestone in the realm of blockchain security. The reward recognizes CertiK’s pivotal role in uncovering a critical vulnerability dubbed “HamsterWheel.”

The discovery of this vulnerability underscores the importance of proactive cybersecurity efforts and the need to safeguard the resilience of blockchain ecosystems. The “HamsterWheel” vulnerability posed a serious threat to the Sui blockchain network, as it had the potential to bring about a complete shutdown by obstructing the processing of new transactions.

This unique attack leveraged a small payload of around 100 bytes to induce an infinite loop in the validator node. Even after a system reboot, the attack had the capacity to cause persistent damage, underscoring the urgency of addressing the issue promptly.


Sui, a Layer 1 blockchain network built on Move, has been steadily gaining traction since its launch in May. The platform has cultivated numerous partnerships, including its recent integration with OKX Web3 Wallet, as it focuses on incentivizing developers to build on its network. With a robust user base, Sui boasts 871,630 active addresses and over 2 million NFTs minted across 963 collections.

CertiK’s expertise and unwavering commitment to blockchain security played a critical role in identifying and mitigating the “HamsterWheel” vulnerability. Their employment of cutting-edge AI technology and dedication to staying ahead of security developments have solidified their standing as a trusted leader in the industry.

The collaboration between Sui and CertiK serves as a testament to the significance of robust security measures and proactive threat identification within the blockchain space. Sui’s decision to reward CertiK with a substantial bounty underscores the platform’s unwavering dedication to upholding a secure and resilient blockchain network.
