imtoken will never ask for your seed phrase, private key or verification code. Always review the address, network and request details before transferring, signing or approving.

Approval Security

Approval risk is often not about someone logging into a wallet; it comes from permissions previously granted to contracts. Understanding spenders and allowances helps manage exposure.

Approvals and connections are different actions

Approvals and connections are different actions is a distinct part of understanding Approval Security.

Within Approval Security, approvals and connections are different actions should not be treated as an isolated concept. Real actions often involve an account, a selected network, on-chain state and an explicit user decision. A reliable approach is to define the task first and then review every input that can change the outcome. A familiar interface or a sense of urgency is not a reason to approve a request you cannot explain.

When reviewing approvals and connections are different actions, prefer information that can be independently checked. Network names, addresses, contract identifiers, transaction hashes and block-explorer records are usually more useful than screenshots or messages from third parties. A wallet can surface these details, but users still need to distinguish between being connected, signing a message, granting an approval and seeing a confirmed transaction.

A practical routine is to divide the process into before, during and after. Before the action, verify the source and environment. During confirmation, read the network, address, amount, permissions or contract target. Afterward, verify the result on-chain. This makes it easier to diagnose pending transactions, display issues or DApp state mismatches without guessing.

Practical check

  • Confirm that the action matches the goal of Approvals and connections are different actions
  • Never provide a seed phrase, private key or verification code to anyone
  • Stop when a signature, approval or address change cannot be explained

Seed phrases and private keys remain under the user’s control; official staff will not ask for them. On-chain transactions usually cannot be reversed by a wallet alone, and third-party DApps and smart contracts may carry risk.
