Vitalik Buterin floats TX 'simulations' to enhance crypto security

Crypto users would specify what onchain action they want and then click “OK” or “Cancel” after seeing a transaction simulation of 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.

Buterin said an intent security approach could involve designing systems that double-check user actions, and could apply to Ethereum wallets and smart contracts, but also apply more broadly, such as operating systems and hardware.
