AI has great potential in the Web3 field. AI can be used for security audits of smart contracts, quickly identifying potential vulnerabilities by analyzing large amounts of code data, thereby reducing risks. It can also assist in risk management in decentralized finance (DeFi), providing investors with more accurate risk assessments through data analysis and predictive models. In addition, AI can optimize user experience, for example, by using natural language processing technology to make it easier for users to interact with the blockchain.
