CZ: Self-Custody Wallet Vulnerability Fixes Cannot Protect Previously Created Wallets

According to Odaily, in response to the persistent attacks on Coldcard wallets, Binance co-founder CZ reposted on X stating that for self-custody wallets, developers fixing vulnerabilities cannot resolve the risks associated with previously generated wallets, and developers are unable to directly contact users of air-gapped devices.CZ stated that users' wallets may still be exposed to attack risks before any action is taken. He emphasized that he still supports the self-custody model, but self-custody means users need to bear more security responsibilities.
