Start with the core concept: permission scope

Security is an ongoing practice built from backups, careful review, rejecting suspicious requests and managing permissions over time.

Approvals should be managed like ongoing permissions, especially unlimited allowances, unfamiliar contracts and permissions that are no longer needed.

Understanding permission scope is less about memorizing a definition and more about knowing where it appears in a real workflow, which details deserve attention, and what can go wrong when the wrong network or request is accepted. imtoken frames the topic around practical decisions: confirm the account and network first, read the request carefully, and only then decide whether to continue.

In a multi-chain environment, permission scope often appears together with addresses, gas, transaction status and contract information. Similar-looking addresses do not make different networks interchangeable, and assets with the same symbol may come from different contracts. Cross-check the network, contract address, recipient and transaction details instead of relying on a ticker or a visual label alone.

Before proceeding, be clear about what you are connecting, signing, approving or sending. A wallet can display the request it receives, but it cannot independently guarantee that a third-party DApp, contract or service is trustworthy. Requests with an unclear origin, unusually broad permissions, unexpected amounts or unexplained actions should be rejected until the source can be verified.

A simple checklist for permission scope turns a complex flow into a few details that can be verified independently. If a request cannot be explained, there is no need to continue simply to finish the process. Re-checking the network, source and contract details before acting is usually more effective than trying to resolve an avoidable on-chain mistake later.

Practical checks

  • Confirm the network, account or source associated with permission scope
  • Never share a seed phrase, private key or verification code
  • Read the full request before approving an asset or permission change

What to verify before acting: unlimited approvals

How to make practical decisions: contract verification

Common mistakes and risk signals: revoking approvals

Security is an ongoing practice built from backups, careful review, rejecting suspicious requests and managing permissions over time.

Understanding revoking approvals is less about memorizing a definition and more about knowing where it appears in a real workflow, which details deserve attention, and what can go wrong when the wrong network or request is accepted. imtoken frames the topic around practical decisions: confirm the account and network first, read the request carefully, and only then decide whether to continue.

Review and ongoing management: incident response

Security is an ongoing practice built from backups, careful review, rejecting suspicious requests and managing permissions over time.

Similar-looking addresses do not make different networks interchangeable, and assets with the same symbol may come from different contracts.

A wallet can display the request it receives, but it cannot independently guarantee that a third-party DApp, contract or service is trustworthy. Requests with an unclear origin, unusually broad permissions, unexpected amounts or unexplained actions should be rejected until the source can be verified.

Good practice continues after the action is complete. Use the transaction hash to review on-chain status, confirm the expected network and recipient, and check whether an approval or DApp session remains active. Removing permissions that are no longer needed reduces unnecessary exposure and makes future reviews easier.
