The Ethereum community has proposed the new standard ERC 7265 to address DeFi hacking attacks

ChainCatcher message, Ethereum community members proposed the ERC 7265 new standard, which will enable DeFi protocols to integrate a "circuit breaker," allowing DeFi protocols to add a backstop in their smart contracts to prevent the loss of all tokens in the event of a hack.

The ERC 7265 standard is a proposed standard, and it remains to be seen whether the Ethereum core team will accept and implement it as the final standard. (source link)
