Start with clear boundaries
The most important first step in Device Security is understanding which facts come from the wallet interface, which come from the blockchain, and which depend on a third-party service. Treating these as separate layers helps prevent a temporary display state from being mistaken for a final on-chain result.
Prefer information that can be independently checked: the network, destination address, transaction hash, contract address, approval target or validator state. Familiar branding or polished interface language is not a substitute for verification.
For Device Security, keep the network, account, target and outcome as separate checkpoints. If a balance display changes, a transaction is pending or a third-party page behaves unexpectedly, start with public on-chain facts instead of repeating a signature or sending again.
Understand the lifecycle of an action
A practical way to reason about Device Security is to separate an action into preparation, request, wallet confirmation, network processing and final verification. Problems that look similar on screen can originate at very different stages, from a wrong parameter to congestion or a third-party application issue.
Many on-chain actions are difficult or impossible for a wallet to reverse on its own. Reviewing the summary, network and destination before submission is therefore more reliable than looking for a remedy afterward.
Public computers can retain browser data, clipboard contents or malicious extensions, while public Wi-Fi introduces additional uncertainty. Sensitive wallet actions are better performed on a device and network you control.
Remote-control software turns anything visible on your screen into something another party may be able to see. End the session immediately if anyone asks you to reveal a seed phrase, private key or verification code.
For Device Security, keep the network, account, target and outcome as separate checkpoints. If a balance display changes, a transaction is pending or a third-party page behaves unexpectedly, start with public on-chain facts instead of repeating a signature or sending again.
Build security into the workflow
Security should be part of every stage of Device Security, not a warning shown at the end. For any request involving a key, signature, approval or transfer, ask who is making the request, what permission is being requested, what it can affect and whether it can later be revoked.
Seed phrases and private keys remain under the user’s control. imtoken personnel will not ask for them. Never send a seed phrase, private key or verification code to anyone, and be cautious with urgency, remote-control requests or unfamiliar links.

Practical checklist
- Verify the network and destination
- Read the signature or approval target
- Keep non-sensitive data such as transaction hashes
Verify the outcome independently
After a Device Security action, do not rely on a single success message. Check the transaction hash, explorer status, network and destination address. For approvals, also review the approved contract and allowance to confirm that the final permission matches what you intended.
If the outcome is unclear, keep non-sensitive diagnostic information such as the transaction hash, network name and sequence of steps. A seed phrase, private key or verification code is never appropriate troubleshooting material.
