Approval Security

Define the security boundary first

Verification focus

When working with Approval Security, start by keeping approval targets, allowance amounts, and approval duration in the same context. Create a three-stage approval review process—before approval, after approval and during ongoing permission management. A familiar label or icon is not enough on its own; the active network, account, address, contract or transaction record should agree with the action you intend to take. For consequential actions, understanding exactly what is being requested matters more than moving quickly through a confirmation screen.

A practical Approval Security workflow can follow a consistent sequence: confirm the source and destination, review approval duration, then verify unlimited allowances in the correct network context, and finally inspect DApp origin together with the possible on-chain consequence. Only after that review should you sign or submit. Keep non-secret evidence such as a transaction hash or contract address so the result can be checked later.

The central risk around Approval Security is that Long-lived or excessive approvals can expand future exposure, especially if the approved contract or DApp later becomes compromised. If an unexpected network switch, unfamiliar contract, excessive approval, changed address or urgency tactic appears, stop before confirming. Seed phrases, private keys and verification codes are never normal troubleshooting material; imtoken staff will not ask for them and they should not be submitted through websites, chats or remote-control tools.

Recognize the most common threat scenarios

Key observations during the workflow

For “Recognize the most common threat scenarios”, allowance amounts establishes the starting point, approval duration helps explain whether the process is progressing as expected, and unlimited allowances is often the detail that can be cross-checked against wallet history or public on-chain data. If those facts conflict, stop and verify the source again. Transfers, signatures, approvals and cross-layer actions deserve a complete review even when the interface looks familiar.

It also helps to separate interface information from verifiable on-chain facts. unlimited allowances may describe the intent of an action and DApp origin may provide useful status context, but important decisions should still be checked against revoking permissions no longer needed and the relevant network record. Wallet labels, token symbols, DApp copy and promotional language can all be imitated, so familiarity is not proof of authenticity.

• Review approval targets in the correct network context.
• Review allowance amounts in the correct network context.
• Review approval duration in the correct network context.
• Review unlimited allowances in the correct network context.
• Review DApp origin in the correct network context.

What to do after noticing something suspicious

Do not let urgency replace judgment
