Verify, don’t trust. The iOS version of the OKX Wallet was found to have a remote code execution vulnerability by the security company CertiK at the end of 2023. As a seasoned user who has lost assets in both MetaMask and OKX Wallet, I sincerely advise everyone to keep the majority of their assets on top-tier CEXs. Don’t blindly trust those decentralized fundamentalist theories. Self-custody is an unbearable burden for ordinary people, as most lack the ability to manage wallet security.
