Conor Grogan, director of Coinbase, tweeted that he dumped a live Ethereum contract into GPT-4, and GPT-4 instantly found security holes and even showed how to exploit them for attacks. Conor Grogan said that the contract was indeed hacked in 2018 through the vulnerability pointed out by ChatGPT. In addition, he said that he also tried Euler's smart contract, but it could not be processed by ChatGPT-4 because the contract was too long. AI will eventually make smart contracts safer and easier to build, according to Conor Grogan.
