Verify the application source
Verify the application source — practical checks
A useful way to approach this topic is to separate what the interface displays from what the blockchain actually records. Web3 & DApps is best understood through the specific decisions a user makes, not just through interface labels. Follow the complete flow from connection to account requests, signatures, approvals and disconnection.
For practical review, split the request into five layers: network, address or contract, asset or permission, network fee, and resulting transaction state. The network tells you where execution occurs; the address or contract identifies the target; the asset or permission defines the scope; gas reflects network execution cost; and the transaction hash provides a durable reference for verification. If an application shows only vague language such as “continue”, “verify” or “claim”, use the wallet confirmation screen to inspect what is actually being requested.
Keep seed phrases and private keys under your own control. imtoken personnel will not request a seed phrase, private key or verification code. Before transferring, signing or approving, check the network, destination or contract and the exact action. Confirmed blockchain transactions are generally not reversible by a wallet provider, and third-party DApps and smart contracts can introduce independent risks.
That habit makes it easier to reason from verifiable on-chain evidence even when an interface changes.
Connection is not blanket permission
Connection is not blanket permission — practical checks
Most mistakes in this area come from missing context rather than from a single button press. A practical check for this topic is: verify the application source; then consider connection is not blanket permission before moving to the next action.

If a critical field cannot be verified, stopping and checking independently is safer than completing the action under time pressure.
Different kinds of signatures
Different kinds of signatures — practical checks
Start with the user decision: identify the network, counterparty or contract, requested permission and expected result before confirming. On-chain activity is contextual. Network, address, contract, amount, permissions and transaction status can each change the meaning of what the wallet is showing.

There is no benefit in rushing an unfamiliar signing request; understanding the request should come before confirmation.
Manage connections and approvals afterward
Manage connections and approvals afterward — practical checks
A repeatable verification habit is more durable than memorizing one interface because networks and applications can change over time. Connecting a wallet is not permission to approve every subsequent request. Check the requesting domain, network, contract or spender, requested allowance and the exact action before signing.

The goal is to be able to explain which network is involved, who or what the request targets, what permission is being granted and what on-chain outcome may follow.
Safety and risk reminder
Keep seed phrases and private keys private. Third-party DApps, smart contracts and services can carry independent risks. Blockchain transactions are generally not reversible by a wallet provider after confirmation.
