Core concepts
From a risk perspective, contract addresses and long-lived approvals deserve an independent review. Once a transaction is confirmed on-chain, a wallet normally cannot reverse it unilaterally. DApps and smart contracts can also introduce permission and contract risks, so every signature, approval and transfer should be understood before it is accepted.
For approval targets, first define its role in the current task, then check whether allowance amounts and contract addresses are consistent. When long-lived approvals is involved, do not rely only on a default option; understand which account, asset or permission it may affect. For revoking approvals, use on-chain records and the actual status as the source of truth. imtoken will not ask users to enter a seed phrase, private key or wallet recovery phrase on a web page, and it will not require remote control of a device for sensitive wallet actions.
- Confirm: approval targets
- Cross-check: allowance amounts and contract addresses
- Review carefully: long-lived approvals
- Verify afterward: revoking approvals
Checks before you act
After a Token Approvals task is completed, review revoking approvals and approval targets to make sure the outcome matches the intent. Long-lived approvals and persistent connections should be revisited periodically. Good wallet hygiene is a repeated process of checking critical details and retaining traceable on-chain information, not a one-time setting.
For allowance amounts, first define its role in the current task, then check whether contract addresses and long-lived approvals are consistent. When revoking approvals is involved, do not rely only on a default option; understand which account, asset or permission it may affect. For approval targets, use on-chain records and the actual status as the source of truth. imtoken will not ask users to enter a seed phrase, private key or wallet recovery phrase on a web page, and it will not require remote control of a device for sensitive wallet actions.
- Confirm: allowance amounts

- Verify afterward: approval targets
How to evaluate a live request
To understand Token Approvals, treat contract addresses and long-lived approvals as parts of the same on-chain workflow. The interface is only the entry point; the selected network, current chain state and permission scope determine what actually happens. Confirm the destination, source and network before continuing so the meaning of the request stays clear.

Risks and boundaries
long-lived approvals rarely appears in isolation. It often intersects with revoking approvals and approval targets. A useful pattern is to separate each action into four checks: identify the object, verify the network, review permissions, and confirm the result. If one of those checks cannot be completed, stop and verify rather than relying on an unfamiliar site or remote instructions.

How to verify the outcome
When using imtoken for Token Approvals, prioritize information that can be independently verified, such as addresses, network names, contract addresses, transaction hashes and block-explorer records. Visual design, urgency messages or claims from an unknown support account are not substitutes for verifiable on-chain details.
For revoking approvals, first define its role in the current task, then check whether approval targets and allowance amounts are consistent. When contract addresses is involved, do not rely only on a default option; understand which account, asset or permission it may affect. For long-lived approvals, use on-chain records and the actual status as the source of truth. imtoken will not ask users to enter a seed phrase, private key or wallet recovery phrase on a web page, and it will not require remote control of a device for sensitive wallet actions.
- Confirm: revoking approvals
- Cross-check: approval targets and allowance amounts
- Review carefully: contract addresses
- Verify afterward: long-lived approvals
Practical checklist
- Never share your seed phrase, private key or verification code.
- Verify the address, network and amount before sending.
- Review each DApp signature and token approval independently.
- Use transaction hashes and block explorers to verify on-chain status.
- Revoke approvals and disconnect sessions that are no longer needed.
