Crypto users would specify the onchain action they want, then click “OK” or “Cancel” after seeing a transaction simulating that action.
Ethereum co-founder Vitalik Buterin has suggested using “transaction simulations” and other similar features to improve the user experience and security of Ethereum wallets and smart contracts.
In a post to X on Sunday, Buterin argued that security and user experience are not separate fields, as both revolve around user intent — ensuring protocols are doing what users intend them to do.
Buterin said an intent-based security approach could involve designing systems that double-check user actions and could apply to Ethereum wallets and smart contracts, as well as more broadly to operating systems and hardware.
