The individual also posted several pages of notes to the blockchain, disclosing why they hacked the firm and the offers Poly Network made to them.

In a twist that's worrying some cyber-security experts, the hacker claims the firm offered to pay $500,000 if they returned the stolen assets, as well as a promise of immunity from prosecution.

By Thursday evening, Poly Network posted an update that most of the remaining assets in the hacker's possession had been transferred to a digital wallet controlled by both the hacker and the company.

"The hacker still holds $33.4m of stolen Tether [tokens] - because it has been frozen by Tether themselves," Tom Robinson, co-founder of Elliptic, a London-based blockchain analytics and compliance firm, told the BBC.

He added that it could be seen on the blockchain that "a few thousand dollars' worth of various other tokens" were being held onto by the hacker.
