Japanese crypto exchange Liquid said that bitcoin, ether, XRP and TRX coins were stolen in the hack, and it was trying to track down the crypto.
The case puts the spotlight on UK's court system's capability to track cybercriminals. It is also one of the first public ones involving Binance.
Poly Network said it hopes the hacker will contribute to the blockchain sector's development upon accepting the $500,000 reward, Reuters reported.
The tool must maintain a database of crypto wallets and monitor the behavior of market participants.
