Decentralized exchange (DEX) protocol KyberSwap has offered a 10% reward to the hacker who stole $47 million from the protocol. The reward offer was made in response to a message left on the blockchain by the hacker.
Details of the $4.7 Million Reward Offered to the Hacker
Earlier this week, KyberSwap’s Elastic pools were targeted in a hack attack, resulting in the theft of funds from various blockchains, including Arbitrum, Optimism, Ethereum 
$3,113, Polygon, and Base. Following the attack, the hacker left a message on the blockchain, stating their intention to negotiate the fate of the funds with the team.
In response to the message on the blockchain, KyberSwap has offered a deal to the hacker. The team that responded to the message on the blockchain offered the hacker a 10% reward, approximately $4.7 million, if they return 90% of the stolen funds to a specified wallet address by November 25th at 09:00 AM GMT.
KyberSwap Co-Founder Gives Ultimatum to Hacker
Victor Tran, co-founder of KyberSwap, stated in the message left on the blockchain that the hacker can choose to return the funds as part of the offered reward or continue to remain on the run. He did not rule out the possibility of giving an ultimatum.
The reward offer is part of KyberSwap’s efforts to mitigate the consequences of the attack and restore liquidity providers. Blockchain security company Beosin revealed that the security vulnerability that led to the attack was related to a problem with the tick range limits in KyberSwap’s liquidity pools. The hacker exploited this vulnerability to artificially double the liquidity and then drain it.
Meanwhile, the service token of the protocol, KNC, has been attempting to recover after experiencing a sharp drop following the hacker’s attack. At the time of writing, the altcoin is trading at $0.7287, up 0.43% in the last 24 hours.
