Critical Vulnerability on Polkadot Parachains Discovered, $200 Million at Risk

A security researcher discovered a potential vulnerability that could have resulted in the theft of up to $200 million from three Ethereum-compatible parachains on the Polkadot network: Moonbeam, Astar Network and Acala. The vulnerability was found in June in Frontier, a software used for “wrapping” native tokens on the three blockchain projects on the Polkadot network.
