Vitalik Buterin, co-founder of Ethereum, has proposed an innovative approach to enhance both the security and user experience of cryptocurrency transactions through simulated transactions. In a recent post on his social media platform X, he suggested that users should first simulate a transaction before confirming it. This means users would specify their desired action on-chain, view a simulation of how the transaction would proceed, and then decide to either confirm ("OK") or cancel ("Cancel"). Buterin emphasized that security and user experience are inherently linked, as both revolve around ensuring that protocols align with user intent. By implementing an "intent-based" approach, systems can verify actions and prevent unintended outcomes. This concept, according to Buterin, could be applied not only to Ethereum wallets and smart contracts but also to operating systems and hardware. The idea is rooted in the belief that verifying user actions through simulation can reduce errors and malicious activities. For instance, a user might review a simulated transaction to ensure it aligns with their intended purpose before finalizing it. This approach could prevent accidental or intentional misuse of funds or smart contracts by providing an added layer of verification. The significance of this proposal lies in its potential to
