Wormhole Bridge is a cross-chain messaging and token bridge protocol originally developed by Certus One, later owned by Jump Crypto, enabling asset transfers between Solana, Ethereum, and other blockchains. On February 2, 2022, an attacker exploited a signature verification flaw in the Solana-side smart contract to fraudulently mint 120,000 wrapped ETH (wETH) worth approximately $320–326 million without posting collateral, making it the second-largest DeFi exploit in history at the time. Jump Crypto replenished the stolen ETH within 24 hours to prevent ecosystem collapse, and a court-authorized counter-exploit in February 2023 recovered approximately $140 million of the remaining stolen funds.
