On August 10, unknown persons hacked the Poly Network inter-network protocol and stole $611 million in various cryptocurrencies. The project team called on the exchanges to block the stolen funds.

“We regret to inform you that the Poly Network has been attacked on the Ethereum, Binance Smart Chain and Polygon networks. We urge the miners of the affected blockchains and crypto exchanges to blacklist tokens coming from the above addresses,” the project team wrote.

According to preliminary estimates, the attackers stole $273 million in the Ethereum network, $253 million in the Binance Smart Chain network and $85 million in the USDC in the Polygon network. Funds in the tokens WBTC, WETH, RenBTC, DAI, UNI, SHIB, FEI and others were affected. The hack was the largest in the history of the DeFi segment.

After the theft, Tether blacklisted USDT on Ethereum, which was stolen during the attack, for about $33 million.

“We are aware of the Poly Network exploit. Although no one controls BSC (or ETH), we coordinate with our security partners to actively help. We do not give guarantees, but we will do everything in our power,” CZ said.
