Start with non-negotiable security principles
Security is easier to use when seed phrase and private key are understood in the same operational context. A seed phrase can commonly restore a set of wallet accounts, making it more sensitive than an ordinary login password. If exposed, another party may be able to restore the wallet elsewhere. A private key directly controls the signing authority of an on-chain account. Anyone who obtains it may be able to produce valid signatures for that account. These situations are rarely improved by clicking faster; separate the object, permission, and expected result instead.
Do not treat a familiar interface as proof that a request is trustworthy. Around seed phrase and private key, identify the source of the request, the permission being granted, and whether an on-chain result may follow. imtoken will never ask for a seed phrase, private key, or verification code. Blockchain transactions also generally cannot be unilaterally reversed by a wallet, so review before confirmation matters more than recovery attempts afterward.
Practical checkpoint
- Prefer offline backup, avoid screenshots and messaging apps, and never hand it to someone claiming to be support.
- A private key is not a support credential, reward claim code, or website identity check; stop immediately if one is requested.
- Before any transfer, signature, or approval, confirm that the network, address, and request details match the action you intended.
Recognize common risk scenarios
Security is easier to use when token approval and phishing are understood in the same operational context. A token approval allows a specified contract to use a token within an allowance. It is not a normal login step, and an excessive allowance or incorrect target increases exposure. Phishing uses look-alike domains, copied interfaces, and urgency to persuade users to reveal secrets or authorize unwanted actions. Understanding the boundary is more important than rushing to completion because on-chain actions can create difficult-to-reverse outcomes.

Practical checkpoint
- Verify the spender contract, token, allowance, and necessity, and consider revoking approvals that are no longer needed.
- Avoid entering a signing flow directly from unsolicited messages, ads, or group chats.
- Before any transfer, signature, or approval, confirm that the network, address, and request details match the action you intended.
What to do when something looks wrong
Security is easier to use when device security and sending assets are understood in the same operational context. Wallet safety depends on more than a password; system updates, malware, screen sharing, browser extensions, and local file protection all matter. Sending assets creates a transaction that must be signed and broadcast to a network. An error in the address, network, amount, or fee can change the outcome. Putting these concepts together is more useful than memorizing vocabulary without knowing when a check matters.

Practical checkpoint
- Before important actions, disable unnecessary remote-control or sharing tools and keep the operating system and browser current.
- Review the address, network, amount, asset, and fee one by one, and do not skip checks because of urgency or countdown pressure.
- Before any transfer, signature, or approval, confirm that the network, address, and request details match the action you intended.
Turn security into a repeatable habit
Security is easier to use when seed phrase and private key are understood in the same operational context. A seed phrase can commonly restore a set of wallet accounts, making it more sensitive than an ordinary login password. If exposed, another party may be able to restore the wallet elsewhere. A private key directly controls the signing authority of an on-chain account. Anyone who obtains it may be able to produce valid signatures for that account. In practice, the useful habit is to match what the interface shows against the network, address, and actual request details.

Keep seed phrases and private keys under your own control. Do not send them to anyone. Review the address, network, amount, signature text, and approval scope before confirming. Third-party DApps and smart contracts can introduce independent risk.
