Yesterday, blockchain platform Poly Network wrote a letter on Twitter, asking the individual to get in touch "to work out a solution".

Poly Network posted on Twitter that it had been sent digital tokens relating to three crypto-currencies, including $3.3m worth of Ethereum, $256m worth of Binance Smart Chain (BSC) and $1m worth of Polygon.

The hacker also took to one of the blockchains to publish a three-page-long Q&A session, where he essentially "interviewed himself", according to Tom Robinson, co-founder of Elliptic, a London-based blockchain analytics and compliance firm.

"I know it hurts when people are attacked, but shouldn't they learn something from those hacks?" he wrote in the notes posted to the blockchain.

The hacker added that it had taken him all night to find a vulnerability to exploit. He said he was worried that Poly Network would patch the security flaw quietly without telling anyone, so he decided to take millions of dollars in crypto-currency tokens to make a point.
