#Poly Network urges users to withdraw after exploit affects 57 crypto assets.

Following a July 2 attack on the cross-chain bridge platform Poly Network, which allowed a #hacker to create billions of tokens out of thin air for profit, more information is becoming available.

After hackers were able to modify a smart contract function on the cross-chain bridge protocol, Poly Network acknowledged it was the latest #DeFi exploit victim in a tweet on July 2 and announced it would temporarily cease services.

The researchers revealed the vulnerability targeted 57 cryptocurrency assets across 10 blockchains in the most recent version, including #Ethereum , BNB Chain, Polygon, #Avalanche , Heco, OKx, and other platforms like Metis.
