{Hardware} wallets aren’t secure both
Previous to the Pectra replace, the {hardware} pockets was deemed safer. However that's not the case anymore, based on Hacken's on-chain researcher Yehor Rudytsia.
Rudytsia says {hardware} wallets are on the similar danger as sizzling wallets by way of signing malicious messages. “If it's achieved, all of the funds will disappear rapidly,” he mentioned.
