Core security principles
A useful way to understand this topic is to separate the wallet interface from the rules enforced by the blockchain. The wallet helps users inspect and submit actions, while balances, ordering, and contract execution are recorded by the selected network. The device hosting a wallet shapes the security environment. System updates, screen locks, app sources, remote-control software, and public-network habits all affect exposure. For “Device Security”, a practical first pass is to identify system updates, screen lock, and app sources, then use public Wi-Fi, shared computers, and remote control to understand what the action can change and where its result should appear.
From a user perspective, system updates answers what is being handled, screen lock identifies the participating account or object, and app sources determines which rule set applies. When these do not line up, a screen may still look normal while the user faces missing asset displays, insufficient fees, an incorrect request target, or difficulty locating the relevant on-chain record.
For long-term use, build system updates, app sources, and shared computers into a routine review, and periodically revisit persistent state related to remote control. The purpose of this knowledge is not to add friction; it is to make important confirmation points understandable before an action becomes difficult to reverse.
Third-party DApps, smart contracts, and network services can introduce their own risks. imtoken can present requests and on-chain information, but it cannot guarantee third-party code or unilaterally reverse a transaction that has already been confirmed on a blockchain. Important actions related to Device Security should therefore be based on a clear understanding of the request.
Recognize high-risk situations
Most practical mistakes do not come from the location of a button. They come from mixing up addresses, networks, assets, and permissions. A deliberate review process is more dependable than memorizing one fixed click path. The device hosting a wallet shapes the security environment. System updates, screen locks, app sources, remote-control software, and public-network habits all affect exposure. For “Device Security”, a practical first pass is to identify system updates, screen lock, and app sources, then use public Wi-Fi, shared computers, and remote control to understand what the action can change and where its result should appear.

When these do not line up, a screen may still look normal while the user faces missing asset displays, insufficient fees, an incorrect request target, or difficulty locating the relevant on-chain record.
In a real workflow, review screen lock first, then verify app sources and public Wi-Fi, and finally inspect the status associated with shared computers. Similar names do not prove that networks, assets, or contracts are interchangeable, and a previously successful action does not make a new permission request automatically safe.
Third-party DApps, smart contracts, and network services can introduce their own risks. imtoken can present requests and on-chain information, but it cannot guarantee third-party code or unilaterally reverse a transaction that has already been confirmed on a blockchain. Important actions related to Device Security should therefore be based on a clear understanding of the request.
A step-by-step review
This topic connects directly to everyday wallet activity. Any action involving assets, signatures, or permissions should begin with the request source, continue with the network and target, and end with an understanding of whether the effect can be reversed. The device hosting a wallet shapes the security environment. System updates, screen locks, app sources, remote-control software, and public-network habits all affect exposure. For “Device Security”, a practical first pass is to identify system updates, screen lock, and app sources, then use public Wi-Fi, shared computers, and remote control to understand what the action can change and where its result should appear.
From a user perspective, system updates answers what is being handled, screen lock identifies the participating account or object, and app sources determines which rule set applies. When these do not line up, a screen may still look normal while the user faces missing asset displays, insufficient fees, an incorrect request target, or difficulty locating the relevant on-chain record.
A useful request review asks a sequence of questions: Where did it originate? Which system updates is involved? Which app sources applies? Does it change public Wi-Fi? Where should shared computers be visible afterward? If any answer is unclear, stop before confirming and re-check the context.
Third-party DApps, smart contracts, and network services can introduce their own risks. imtoken can present requests and on-chain information, but it cannot guarantee third-party code or unilaterally reverse a transaction that has already been confirmed on a blockchain. Important actions related to Device Security should therefore be based on a clear understanding of the request.
- Verify system updates
- Confirm app sources
- Locate shared computers
- Never submit a seed phrase, private key, or verification code
What to do when something looks wrong
Blockchain activity can be publicly verifiable without being casually reversible. Pre-action review, understanding the request, and post-action transaction checks should therefore be treated as one continuous habit. The device hosting a wallet shapes the security environment. System updates, screen locks, app sources, remote-control software, and public-network habits all affect exposure. For “Device Security”, a practical first pass is to identify system updates, screen lock, and app sources, then use public Wi-Fi, shared computers, and remote control to understand what the action can change and where its result should appear.

When these do not line up, a screen may still look normal while the user faces missing asset displays, insufficient fees, an incorrect request target, or difficulty locating the relevant on-chain record.
Common mistakes include ignoring app sources, trusting a page name without checking screen lock, treating shared computers as proof of immediate finality, or continuing with remote control on an unfamiliar site. A request being technically clickable does not mean it should be approved; each request needs its own review.

If something looks wrong, preserve information that is safe to share publicly, such as the network name, public address, and shared computers, then use wallet history or an appropriate block explorer to check on-chain state. Do not provide a seed phrase, private key, recovery phrase, or verification code to anyone in order to get help.
