"Israeli startup Kirobo has announced the launch of an “undo transaction” button for Ethereum (ETH) blockchain transactions. Previously available exclusively for Bitcoin, the feature is now open to ETH transactions as of Nov 12, to be followed later by ERC-20 token transfers. According to the Israeli government-backed company, the feature will eventually include protection against sending funds to smart contracts that do not accept deposits. Such transactions previously resulted in an irretrievable token loss. Feature is now available to ETH holders using MetaMask and WalletConnect."
