Core concepts
From a risk perspective, transaction data and approval impact 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 contract addresses, first define its role in the current task, then check whether function calls and transaction data are consistent. When approval impact is involved, do not rely only on a default option; understand which account, asset or permission it may affect. For failure handling, 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: contract addresses
- Cross-check: function calls and transaction data
- Review carefully: approval impact
- Verify afterward: failure handling
Checks before you act
After a Smart Contract Interaction task is completed, review failure handling and contract addresses 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 function calls, first define its role in the current task, then check whether transaction data and approval impact are consistent. When failure handling is involved, do not rely only on a default option; understand which account, asset or permission it may affect. For contract addresses, 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.

- Verify afterward: contract addresses
How to evaluate a live request
To understand Smart Contract Interaction, treat transaction data and approval impact 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
approval impact rarely appears in isolation. It often intersects with failure handling and contract addresses. 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 Smart Contract Interaction, 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 failure handling, first define its role in the current task, then check whether contract addresses and function calls are consistent. When transaction data is involved, do not rely only on a default option; understand which account, asset or permission it may affect.

- Confirm: failure handling

- Review carefully: transaction data
- Verify afterward: approval impact
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.
