Wormhole token bridge lost $ 321 million. Wormhole Token Bridge is a bridge that allows users to transfer methods between Ethereum Solana and others. The solemn part of this software had a problem that led to 120k wETH being stolen.

Wormhole offered a $ 10 million reward for returning the funds and announcing to members that everything was fine and the money would be returned.It is the second-largest achievement of DeFi (Decentralized Finance, technology that eliminates the control that money has over money) of all time, immediately after the $ 600 million cryptocurrency robbery from Poly Network, and is the biggest attack so far on Solana, a rival to Ethereum that is gaining ground in the non-fungal token (NFT) and decentralized finance ecosystems.Ethereum is the most widely used blockchain network and a major player in the DeFi world, where programmable pieces of code known as smart contracts can replace intermediaries such as banks and lawyers in certain types of business transactions. A more recently introduced competitor, Solana, is becoming more and more popular because it is cheaper and faster to use than Ethereum.

Wormhole platform offCryptocurrency holders often do not operate exclusively within a single blockchain ecosystem, so developers have built bridges to allow users to send cryptocurrencies from one chain to another. Wormhole is a protocol that allows users to move their assets between Solana and Ethereum.Developers representing Wormhole have confirmed the attack on their Twitter account, saying the network is “shut down for maintenance” while analyzing a “potential exploit”. The official website of the protocol is currently offline.An analysis by blockchain cybersecurity firm CertiK shows that the attacker’s profits so far amount to at least $ 251 million worth of Ethereum, nearly $ 47 million in Solana, and over $ 4 million in USDC, a stable coin anchored by the price of the US dollar.
