Core principles for Device Security
A wallet connects a user to blockchain networks, but it cannot make every risk decision on the user’s behalf. Critical details still need to be reviewed directly. For Device Security, start with system updates and app sources, then place screen locks inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.
Before acting, identify the account in use, the target network, the asset or contract involved and the on-chain action expected to occur. When public Wi-Fi is relevant, review fee source, request details and confirmation state. When working with public computers, prefer verifiable on-chain information over a label shown by one interface.
After the action, keep enough information to check the result again, such as remote control, the network name, destination address or contract address. On-chain transactions generally cannot be reversed by a wallet acting alone. Third-party DApps and smart contracts carry their own risks, and a wallet connection does not make every request trustworthy.
Using system updates as an example, separate what you see into three layers: interface presentation, the wallet request, and the verifiable on-chain result. The interface explains context, the wallet request defines what will be signed or sent, and the chain records what actually happened. If those layers do not agree, stop and verify the network, address, contract or transaction state before continuing.
Risk scenarios involving system updates and app sources
In a multi-chain environment, three recurring questions help: which network am I on, which asset or contract is involved, and what permission am I granting? For Device Security, start with system updates and app sources, then place screen locks inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.

Recognizing problems with screen locks and public Wi-Fi
Interfaces can look similar while pointing to different networks, contracts and account permissions. Visual similarity is never enough to establish that two actions are equivalent. For Device Security, start with system updates and app sources, then place screen locks inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.

Response steps and checks for public computers and remote control
Understanding this topic starts with the relationship between the account, the selected network and the permission being requested, not with memorizing where a button sits. For Device Security, start with system updates and app sources, then place screen locks inside the actual workflow. This makes the principles portable across different interfaces instead of tying understanding to one screen layout.

Security reminder
Keep your seed phrase and private key under your own control. imtoken personnel will never ask for them or for verification codes. Check the address, network and amount before transferring, and review each DApp signature or approval independently.
