Analysis of the WormHole Exploit
On Feb 2, 2022 an exploit of the Solana-Ethereum bridge was revealed. In this article, we will review how the hack occurred, and how it could have been prevented. The Wormhole works similar to basic bridge principles, whereby assets are sent to a vault contract on the source blockchain, locked in that vault, and a watcher on the second blockchain mints the same form and value of that asset on the second blockchain. A good summary of how bridges can be found in an earlier publication I shared here and here.
