Ledger, Trezor, MetaMask, WalletConnect and the Ethereum Foundation want to close one of the most dangerous breaches in crypto: blind signing. Behind this cold term lies a simple gesture. The user validates a transaction without clearly understanding what it will trigger. The issue became impossible to ignore after the Bybit hack. In February 2025, the exchange acknowledged that an attacker had taken control of an Ether wallet and transferred about 1.5 billion dollars worth of assets to an unknown address. Reuters had then reported that only the Ether cold wallet was affected, according to Bybit CEO Ben Zhou.
